1.2. Safety considerations Before starting any service work that requires disconnection

or removal of any valve part, all services should be made safe by lowering to the ground or adding necessary supports . Failure to do so could result in injury .

Before commencing, ensure that the individual performing the service has proper training and tools for servicing a CMA valve .

If the block is mounted below the tank, service oil may leak when the Pilot Valve is removed . Place a vacuum on the tank line to prevent losing too much oil .

The following pictures orient the reader to the various components of a typical CMA valve assembly . A CMA90 3 section CMA block with Manual Overrides and an Inlet manual override is shown in the following picture .

2.3. Assembly overview


The work section is comprised of two independent spools that act as a pair working to control double acting services, or alternatively as single spools controlling a single acting service (2 single axis services can be controlled from any work section) . Demands to each work section are transmitted over a CAN Bus and power is provided to each work section via a single daisy chain cable arrangement . Each work section has a single pilot valve comprised of on-board electronics, embedded sensors, and two independent 3 position 4 way pilot spools driven by a low power embedded micro controller . The independent pilot spools control the mainstage spools . Control of each work section is done locally by leveraging the on-board electronics and sensors . Each mainstage spool has its own position sensor enabling closed loop position control of the mainstage spool . Further, a pressure sensor is located in each work port, pressure line,

load sense line and tank line . With the up and downstream pressure information known at any time, flow delivered to the service can be controlled by moving the spools to create the appropriate orifice area for the desired flow rate .

Supply pressure is controlled by the Inlet section . Typically, the Inlet receives desired supply pressure from each of the work sections and then controls to the maximum of these demands .

While the above descriptions are the typical methods of control, it should be noted, that other control methods are available and may have been implemented by the application development team . Contact this team for more details on how specifically CMA is being commanded for the machine .

2.5. Manual override operation

Caution should be taken when using manual overrides . Make sure that all personnel are in safe locations and aware that the machine will be moved . Use small movements of the override lever to avoid rapid movement of the machine .

If a work section is not functioning properly, electrical power is lost or hydraulic power is lost, the optional manual override lever on a Work Section can be used to move a service . Note that the valve needs to be ordered with the manual override option; it cannot be added after the fact .

While a work section is comprised of two independent spools that act as a pair working to control double acting services, there is only one work section manual override lever . This lever moves both spools when it is actuated . Without hydraulic power in the supply line, the work section manual override can only allow a service to move under its own weight . Note that the machine’s application cannot be sending commands to CMA (even 0 flow commands) while manual overrides are being used or else the valve will oppose the manual operation .

Inlet manual override. Rotate knob clockwise to raise supply pressure

To power a service, the Inlet needs to be commanded to supply high enough pressure to move the service against its weight . If the Inlet is not functioning or electrical power is lost, an optional manual override on the Inlet’s CV can be used to force the supply line to maximum pressure by rotating the manual override knob clockwise . Again, the Inlet must have been ordered with the manual override ahead of time .

User CAN Connection

User CAN, or UCAN, is the machine’s CAN network that communicates with the VSM .

If the VSM is at the end of the UCAN network, a 120 ohm termination resistor built into the VSM can be used to terminate the UCAN with the installation of a wire jumper, as shown in the left figure below .

If the VSM is in the middle of the bus, no UCAN termination is necessary . The UCAN lines to the VSM must be a stub off of the main CAN harness, as shown in the right figure below .

Interconnect CAN, or ICAN, is the CAN network between the VSM and VSE’s .

120 ohm termination resistors in the VSM and VSE’s circuits can be connected with the installation of wire jumpers each device . Two sets of ICAN pins are available in a VSM or VSE to allow daisy chaining ICAN if a VSM/VSE is in the middle of the CMA system . If no VSE’s exist in a system, it is still necessary to install a jumper to activate one 120 ohm termination resistor on the ICAN bus .

6. Hardware service procedures6.1. Pilot valve replacement procedure

Note 1: Spool replacement requires return to factory .

Note 2: When replacing a pilot valve, it is critical to insert the valves using the supplied guide pins in order to avoid damage to internal components .

Before starting any service work that requires disconnection or removal of any valve part, insure all potential/stored energy sources are at a `zero' state . This would include that the engine/prime mover not be running, the vehicle be on level ground and any implements, scoops, buckets, etc . be lowered to the ground or properly mechanically locked in place . Failure to do so could result in injury or death .

Before commencing, ensure that the individual performing the service has the appropriate user credentials to request an Airbleed and Train of the Pilot Valve being replaced .

If the block is mounted below the tank, service oil may leak when the Pilot Valve is removed .

General information:The pilot valve contains no serviceable items and should be replaced as a unit . It is imperative that only a new or factory-re-conditioned pilot valve is used .

The procedure for replacing a Work Section Pilot Valve (PV) and an Inlet Pilot Valve (CV) is the same .

All pilot valves are mechanically the same . The only consideration when selecting a new pilot valve is the software installed on it . They are not matched to a specific section location . Similarly, an inlet pilot valve can be used on any Inlet section .

Tools and supplies required:

• Spare PV or CV

• Pro-FX Configure 2 .0 and supported CAN card

• 4 mm allen wrench or hex socket

• Torque wrench (Sized for approximately 9 Nm [80 in-lb])

• PV/CV replacement guide pins: 9901134-000

• Eaton PV Seal kit: See seal kit section for part number

• Eaton CV Seal kit: See seal kit section for part number

• PV to PV cable: 6034030-001 (optional)

• VSM to CV cable: 6034031-001 (optional)

Replacement procedure:

1. Export a backup of the CMA system. Reference section 9.4 for the necessary steps.

2. If the software version of the replacement valve does not match the software version of the original valve and the VSM has software version 4.8 or newer, open Pro-FX Configure 2.0, connect to the valve, enter Configuration mode, navigate to the VSM's Replacement tab, and set the replacement flag to manual valve replacements. Save to device.If the software version of the original valve has a major version of 3 (such as 3.8), it must be replaced with a new valve that has a software major version of 3.

3. Ensure that the prime mover and hydraulic pump are both deactivated and all potential/stored energy sources be at a `zero' state. Failure to do so could result in injury or death.

4. Disconnect electrical power to the valve.


5. Disconnect the electrical cables or Terminator from the Pilot Valve being replaced by pressing down on the release tab while pulling back on the cable assembly.

6. Remove two bolts from diagonal corners using 4 mm hex key.


7. Insert two guide rods into the open holes and thread until snug.

8. Loosen bolts to maintain valve in a level position until loose and then remove the two remaining bolts. Depending upon the spool type, there may be springs

compressed by the Pilot Valve lifting it off the face of the valve bank..


9. Remove the valve by lifting it straight up. Care should be taken as the valve has up to two position sensor bodies that fit over the LVDT cores in the main-stage spools.

Damage may occur if the valve is twisted or tipped during removal.

10. Remove and discard O-rings. Make sure to check the bottom of the pilot valve as O-rings may stick to surface.

11. Install seven (7) new o-rings to the main valve face ensuring that they remain in position.


12. Verify LVDT cores were not damaged during removal of the pilot valve. The magnetic strip should be affixed to

the LVDT core. If it has been damaged, refer to section 6.10 on replacing an LVDT core.

Magnetic strip

LVDT core

13. Install the new pilot valve ensuring O-rings remain in place and verifying position sensors pass over LVDT cores in the spools without making contact as the valve

is lowered. The valve should be installed such that the cable assemblies are connected on the same side as the adjacent valves.


14. Place two bolts into diagonal free holes and take turns threading both bolts so that they pull down the Pilot

Valve while maintaining level. Snug bolts until o-rings are compressed.

15. Remove guide pins, install remaining bolts, and thread until O-rings are compressed.

16. Following a crisscross pattern, torque each bolt to 9 ± .5 Nm [80 ± 5 in-lb].

17. Reconnect cables and/or terminator ; take care not to damage the orange perimeter seal. NOTE: The Deutsch DT-style connector is only intended for ~3 insertion cycles. If doubtful about the integrity of the seal, replace the cable assembly completely using the Eaton replacement parts listed in the spare parts lists in section 3.1


18. Ensure that cable retention tab is UP and locked.

19. Reconnect electrical power.

20. Reference the below flow chart for next required steps.

Not locked

Locked


21. Open Pro-FX Configure 2.0

22. Select the appropriate communication protocol of the CMA valve that will be serviced (J1939 or CANOpen) (1). Press “Next” (2) to continue.

23. Either type in the CAN address or ID of the CMA (1a). Or if the address/id isn’t known, press “Scan” (1b). If a CMA valve is found on the network, its address/id will be populated in the ID/ADDRESS field. Note that if there are multiple CMA valves on the network, the CMA with the lowest address/id will be found. Press “Next” (2) to continue.

24. If the replacement is properly identified, a pop-up similar to the following will appear over the Detected Components screen. If you have done a hardware replacement, have a CMA valve with software version 4.8 or later installed, have set the VSM to require user input for valve replacements, and are not seeing this screen as expected, please contact Eaton for support.


25. Select PV/CV Replacement from the dropdown for what type of replacement it was. The following list provides more details on the various options.

a. When to select it: This option should be selected if the user has performed a PV or CV replacement.

b. What it does: This option maintains the PV/CV-specific factory calibration parameters but copies over the work

section/inlet specific factory calibration parameters. It then also copies over the machine-specific parameters. If the new section is used to control the same service as the replaced section and the replaced section was tuned properly, no additional tuning would be necessary.

26. Press “Replace” to begin the replacement mechanism within the valve.

27. During the replacement, the busy indicator will be displayed.

28. Three results are possible from a replacement:

a. Replacement completed successfully. Pro-FX Configure 2.0 will continue on to the next screen.

b. The new valve’s software version is incompatible with the rest of the valves; press ok. Next, reference section 9.8 for more details on how to upgrade software on the valve through Pro-FX Configure. Once the software is updated, cycle power to CMA and recomplete this procedure.

c. Replacement was unsuccessful due either to timing out or a failure in the valve’s process. Close Pro-FX Configure 2.0. Cycle power to CMA and retry this procedure.

29. Reconnect hydraulic power.

30. Request airbleed for all replaced pilot valves. If block is not mounted on the machine with the pilot valves on the top, the pilot line through the block may have drained out. If this is the case, request airbleed all of the work sections and the Inlet, if applicable. Reference section 9.6 for more details on how to initiate airbleeding through Pro-FX Configure.

31. Request training for all replaced pilot valves. Reference section 9.7 for more details on how to initiate training through Pro-FX Configure.


6.2. Work section replacement procedure

Note 1: Main stage spool replacement requires return to factory .


Before commencing, ensure that the individual performing the service has the appropriate user credentials to request an Airbleed, Train and send a Replacement message (if applicable) of the Work Section being replaced .

• Only CMA200 has a fixed displacement option .

• These steps can be completed in reverse to convert from fixed displacement Inlet to variable displacement Inlet .


• DPS: 302AA00067A


• Parameter file from Eaton to convert CV type from VD to FD

• 1 ¼” wrench or hex socket

• Torque wrench (Sized for approximately 178-185 Nm [1575-1637 in-lb]


1. Loosen DPS plug from Inlet.


2. Remove DPS plug from inlet.

3. Note the different between the DPS plug on the left and the DPS valve on the right.


4. Install the DPS valve into the Inlet. Torque to 178-185 N.m

5. The LS port can now be capped.

6. In Pro-FX Configure 2.0, import the parameter file from Eaton to change the CV’s device type from VD to FD.


6.9. Installing manual override handle procedure



• CMA must be ordered with Manual Overrides as the necessary hardware has to be installed into the spools at the plant .

• However, the handles can be removed or installed as desired .

• Additionally, this procedure can be used to move the override handle to point to the other side if so desired .


• Manual override handle, pin, and clips (Provided with valve when shipped from plant)


1. Orient the lever over the hinge and spools.


3. Slide lever over to align hole in hinge and the lever.

2. Set lever on pins.


4. Slide pin into hole in hinge.

5. Slide clip into the other side of the pin to lock pin in place.


6.10. LVDT Core replacement procedure

Note 1: Spool replacement requires return to factory .

Note 2: When replacing a pilot valve, it is critical to insert the valves using the supplied guide pins in order to avoid damage to internal components .


Before commencing, ensure that the individual performing the service has the appropriate login credentials within ProFX Configure to request an Airbleed and Train of the Pilot Valve being replaced .


Caution should be taken when spool is removed to not damage finished surface .

Removing a spool opens up the spool bore to contamination . Use caution to prevent contamination from entering valve .


The LVDT core is the only part of the LVDT that is serviceable in the field . If replacing the LVDT core does not resolve the position sensing issue, the Pilot Valve will need to be replaced .

If multiple spools are removed to replace LVDT cores, make sure to keep track of which spool came from which bore . They must each be put back in the same bore .



• 4 mm allen wrench or hex socket


• PV/CV replacement guide pins: 9901134-000

• Eaton PV Seal kit: See seal kit section for part number

• Eaton CV Seal kit: See seal kit section for part number

• PV to PV cable: 6034030-001 (optional)

• VSM to CV cable: 6034031-001 (optional)

• LVDT Core: 2000-023-00E

• LVDT Installation tool



2. Ensure that the Prime Mover and hydraulic pump are both OFF.


4. Disconnect the electrical cables or Terminator from the Pilot Valve being replaced by pressing down on the release tab while pulling back on the cable assembly.


5. Remove two bolts from diagonal corners using 4 mm hex key.

6. Insert two guide rods into the open holes and thread until snug.


7. Loosen bolts to maintain valve in a level position until loose and then remove the two remaining bolts. Depending upon the spool type, there may be springs compressed by the Pilot Valve lifting it off the face of the valve bank.

8. Remove the valve by lifting it straight up. Care should be taken as the valve has up to two position sensor bodies that fit over the LVDT cores in the main-stage spools. Damage may occur if the valve is twisted or tipped during removal.


9. Remove and discard O-rings. Make sure to check the bottom of the pilot valve as sometimes O-rings stick to that surface.

10. Remove the spool that has the damaged LVDT core from its bore.

Without manual override on work section: The spool should easily be removed from the bore. If not, contamination may have jammed between the spool and bore. Forcing the spool out may damage the spool or bore and would then require a full work section replacement.

With manual override on work section: Removal of the main stage spool with a manual override requires additional steps. If possible without damaging the LVDT core, attempt to remove the LVDT core with the spool left in place. If the LVDT core cannot be removed with the spool in place, the manual override will have to be removed. To do so, follow the steps in section 6.9 to remove the override handle. Then unscrew the manual override plug. Note that to fully disengage the plug from the spool, the plug has to be shifted to the side before pulling it out of the spool, as shown below. The main stage spool can then be removed from the top.

If multiple spools are removed to replace LVDT cores, make sure to keep track of which spool came from which bore. They must each be put back in the same bore.

11. If the magnetic strip has completely separated from LVDT core, remove magnetic strip from spool cavity where the LVDT core resides. If it is not in the spool, it may be in the half of the LVDT installed on the Pilot Valve.

12. Insert the LVDT Installation tool in the cavity with the LVDT core. Rotate tool until it engages with the LVDT core.


13. Using the LVDT Installation Tool, unscrew LVDT core from spool assembly. Do not grip the spool surface with something that will damage its finish.

14. Dispose of old LVDT core.

15. Place new LVDT core in the LVDT Installation Tool.

16. Apply Loctite® Threadlocker Blue 243® to first thread of new LVDT core.

17. Screw new LVDT core into spool and torque to 1.0-1.2 Nm. Make sure when gripping the finished spool surface

not to damage its finish.

18. Install seven (7) new o-rings to the main valve face ensuring that they remain in position.


19. Install the new pilot valve ensuring O-rings remain in place and verifying position sensors pass over LVDT cores in the spools without making contact as the valve is lowered. The valve should be installed such that the cable assemblies are connected on the same side as the adjacent valves.

20. Place two bolts into diagonal free holes and take turns threading both bolts so that they pull down the pilot valve while maintaining level. Snug bolts until O-rings are compressed.


21. Remove guide pins, install remaining bolts, and thread until O-rings are compressed.

22. Following a crisscross pattern, torque each bolt to 9 ± .5 Nm [80 ± 5 in-lb].

27. Request airbleed for all replaced Pilot Valves. If block is not mounted on the machine with the pilot valves on the top, the pilot line through the block may have drained out. If this is the case, request Airbleed all of the Work

Sections and the Inlet, if applicable. Reference the Pro-FX Configure service routines for more details on how initiate airbleeding through that tool.

28. Request rraining for all pilot valves that have replaced LVDT Cores. Reference the Pro-FX Configure service routines for more details on how initiate training through that tool.


6.11. Measure pilot pressure

Note 1: Opening the pilot line will drain the pilot pressure and re-center the pilot valves . All main stage spools will return to their idle position .

Note 2: When opening the pilot line, air can be introduced . Make sure that a method for commanding the pilot valves to airbleed is available to complete after this procedure is performed .


Before commencing, ensure that the individual performing the service has the appropriate login credentials within ProFX Configure to request an Airbleed and Train of the Pilot Valve being replaced .


Caution should be taken when spool is removed to not damage finished surface .


There is no internal pressure sensor for measuring the pilot pressure . A port is available on each CMA block for measuring the pilot pressure line with an external sensor .


• Pro-FX Configure 2 .0 and supported CAN card, or another method for commanding Airbleeding

• 3/16” (for SAE -4 plug) or 6mm (for BSPP G1/4”) allen wrench or hex socket


• Pressure sensor

• For CMA90 or a CMA200 with extension inlet: SAE-4 ORB fitting and additional fittings to mate to pressure sensor

Fault number Fault type Fault Description Suggested actions

103 Critical The valve lost time synchronization with the VSC (i.e. no resynchronization twice in a row)

This fault often occurs when the valve is reset; the PV/CVs lose synchronization with the VSM during the reset process.

Nothing, this fault can be ignored

104 Warning an expected CAN-D msg was not received

Typically due to a fault in the internal CAN bus wiring, although a failed PV could also cause this fault.

Check cable connections between valves and between blocks. Make sure jumpers are properly installed to activate terminating resistors in multi-block systems.

105 Error an expected CAN-D msg was not received twice in a row

Typically due to a fault in the internal CAN bus wiring, although a failed PV could also cause this fault.

Check cable connections between valves and between blocks. Make sure jumpers are properly installed to activate terminating resistors in multi-block systems.

106 Error CRC failed on CRC-protected data stored in EEPROM

There is a mismatch between the data stored on the PV and the back-up data on the VSM. The most common causes of this are:1: A parameter was written to the valve, but a Write Finalize command was not issued.2: Software has been upgraded to a version with a new OD

With the exception of a small number of live updatable OD entries (i.e. Flowshare Method, Stimulus 1 &2), all parameter writes should be Finalized (see Applicatio Developer's Guide). Software updates that require an OD change should be done using a recommended upgrade tool or with assistance from Eaton.

200 Error during start-up the CV was not detected

The system must have a CV to operate, without it, the PVs will stay in a Safe State.

Check wiring and make sure the block containing the CV is connected to the VSM.

201 Information during start-up the CV with the known serial number was not detected

The expected CV serial number was not found during the daisy chaining procedure

If a CV has not been replaced, then check cabling along the entire internal CAN bus. If a CV was replaced, initiate the valve replacement procedure if the valve is configured for manual valve replacement (otherwise, the replacement will happen automatically - see Application Developer's Guide or User's Manual)

202 Information during start-up a PV was not detected An expected PV serial number was not found during the daisy chaining procedure

If a PV has not been replaced, then check cabling along the entire internal CAN bus. If a PV was replaced, initiate the valve replacement procedure if the valve is configured for manual valve replacement (otherwise, the replacement will happen automatically - see Application Developer's Guide or User's Manual)

210 Error Detected configuration is different than stored one

There is a mismatch between the number of valves that the VSM has stored in its Device List, and the valves found during the scanning process that occurs on start-up. This can happen when a block is added or removed, or if the valve-valve wiring is interrupted.

If valves were intentionally added or removed from the system, the valve can be told to clear its Device List and write a new one. This can be done using a service tool such as ProFx Configure 2.0. TAKE CARE that when the Device List is updated, the parameter back-up that is stored on the VSM for the PV/CVs will get over-written. If there is a valve that is not communicating or that has just been replaced, the back-up data will be lost if the Device List is updated before the valve replacement procedure has taken place.

211 Error A data-section on the valve/VSC and its backup are corrupted

This is similar to fault 106, and they often happen together. The Suggested Actions are the same.

214 Error at least one valve is not compatible with the SW-version of the VSC

In order to operate, all of the valves in the system must have the same Major software version. If there is a discrepancy in the major versions, this error will be thrown. Valves with different minor versions can operate together in the same system.

Update the software on the valves so that all valves in the sysetm have the same major SW version.

215 Error at least one valve is not compatible with the OD-version of the VSC

All valves in the system must also have the same OD version to operate. If not, the software should be updated so that this is the case.

Update the software on the valves so that all valves in the sysetm have the same major SW version.

7. Error codes and recommended actions



216 Error daisy chaining proccess failed because of defect, wrong or unexistend cabling

On start-up, the VSM does a Daisy Chaining procedure to identify the serial numbers and configuration of the devices conencted to it. This error is reported if there is a problem in this procedure.

Typically, daisy chaining errors are due to wiring issues, either in the valve-valve wires or in the Interconnect CAN wires between VSM/VSE modules. Make sure all cables are properly seated, there are no short/open pins in the cables, and the CAN lines are properly terminated.

217 Information serial number(s) within VSC NV and Valve DB has been updated because daisy chaining scanned serial number(s) are differ to stored ones in valve DB

This is an informational message to inform you that the valve replacement procedure was completed.

Nothing

218 Information valve ID(s) on valve have been updated because daisy chaining scanned valve ID(s)

This is an informational message to inform you that the valve replacement procedure was completed.

Nothing

219 Information scanned block IDs different to stored ones in valve DB, i.e. Layout Error-> Limp mode not possible

There is a mismatch between the Block IDs stored on the VSM and the ones found during the scanning process that happens on start-up. This is similar to error 210.

The Block IDs are writable parameters, so if a parameter was written to a Block ID entry inadvertently, it can be written back to the correct value. If valves were intenionally added or removed from the system, the valve can be told to clear its Device List and write a new one. This can be done using a service tool such as ProFx Configure 2.0. TAKE CARE that when the Device List is updated, the parameter back-up that is stored on the VSM for the PV/CVs will get over-written. If there is a valve that is not communicating or that has just been replaced, the back-up data will be lost.

220 Error during daisy chaining an error was detected

On start-up, the VSM does a Daisy Chaining procedure to identify the serial numbers and configuration of the devices conencted to it. This error is reported if there is a problem in this procedure.

Typically, daisy chaining errors are due to wiring issues, either in the valve-valve wires or in the Interconnect CAN wires between VSM/VSE modules. Make sure all cables are properly seated, there are no short/open pins in the cables, and the CAN lines are properly terminated.

221 Warning airbleeding was not successful The most common reason for airbleeding to fail is a problem with receiving the Airbleeding Continue command from the application. Airbleeding can also fail if there is another fault present in the system that puts the valve into a safe state (note, not all faults do this).

Check the Airbleeding continue message to make sure it is being sent correctly and frequently enough. High bus traffic could also prevent this message from being received. Check for any other faults reported by the system.

222 Warning training was not successful Training can fail for a number of reasons. One possible cause is that the Training Continue message is not sent correctly or frequently enough. Other training failures can occur if the mainstage spools cannot move (stuck or insufficient pilot pressure), or if there is a problem with the position sensor. The valve may give a warning as to why the training failed, which can help diagnose the problem. Training should also be conducted with an oil temperature above 20C.

Make sure that the Training Continue message is being sent properly and frequently enough. Ensure that there is sufficient pump pressure. If the oil temperature is below 20C, try to warm the block by operating the pump or other services. Many training faults can be bypassed using the Fault Mask parameters, but take note that this can cause the valve to behave incorrectly. This step can be taken to get the valve into an operational state so that further debugging can occur.

223 Warning a training request was received, but denied, as CV is not trained

Since the CV maintains a constant pressure while the PVs are training, it must be trained before the PVs are trained. If this is not done, this error will occur.

Train the CV

225 Error Daisy Chaining failed, because of Timeout Error, i.e. no valve is responding within daisy chaining timeout boundary

The daisy chaining procedure, which scans the system on startup to learn the devices that are connected, did not find any valves. This is likely due to an issue on the valve-valve wiring or the wiring of the internal CAN bus between VSM/VSE blocks.

Check to make sure all wiring is properly connected and the internal CAN bus is properly terminated.



229 Error old known valve layout is not scannable, e.g. some valves are missing or a daisy chain wire is broken

The daisy chaining procedure, which scans the system on startup to learn the devices that are connected, did not find all of the valves it was expecting to find. This is likely due to an issue on the valve-valve wiring or the wiring of the internal CAN bus between VSM/VSE blocks. If a block is disconnected from the system, this can also occur.

Check to make sure all wiring is properly connected and the internal CAN bus is properly terminated.

300-305 Error Sensor Faults These faults are reported if a sensor (positon, pressure, temperature) is giving an invalid signal. Typically, the valve will go into a safe state if one of these faults is detected, but the Limp Mode feature will allow the valve to remain in operation for many operating modes.

Enable Limp Mode if possible. Replace the PV/CV when possible.

307 Error 32V supply sensor reported an out of range value (<32V_min, 32V_max)

The 32 volts that is supposed to be supplied by the VSM/VSE is not received by the PV/CV. This can occur if too many coils (i.e. >14) are simultaneously driven with a full current command (i.e. 100%).

Do not drive multiple coils at 100% PWM, +/-50% is more than sufficient to move the valve to either endstop. If the problem occurs when many coils are not being driven by a high command, check the input voltage at the VSM/VSE. If that is sufficient, the VSM/VSE may need to be replaced.

308 Error temperature sensor (pressure sensor 1) malfunction detected

The voltage reading on the temperature sensor is out of range

Replace the PV/CV

400 Error short circuit on H-bridge One of the coils in the pilot valve is shorted and drawing too much current.

Replace the PV/CV

401 Error short of voice coil to chassis There may be a short in the voicecoil wire.

Replace the PV/CV

500, 501 Warning Negative pressure reading on port 1 or 2 (warning)

A small negative pressure reading was observed on one of the sensors. This can be triggered by noise and minor temperature variation on the sensor. For small values, this is typically not a problem, but if the value becomes more negative over time, it could be a faulty sensor.

Usually nothing, but can replace the PV/CV if desired

502, 503 Error Negative pressure reading on port 1 or 2 (error)

For larger negative values, the fault will be reported as an error. In this case, the sensor or the calibration is more likely to have a problem.

Replace the PV/CV

504 Warning Oil temperature is too low for training Training requires a temperature of about 20 C (varies slightly with Oil Type)

Try to warm the block up be moving other sections or airbleeding for a while. If that is not possible, this fault can be bypassed using the Fault Mask parameter (see the User's Manual), but NOTE: training with oil below 20 C can lead to instability in the position controller once the oil warms up. If the valve is trained cold, it MUST be re-trained with warm oil.

505-514 Warning PV Training faults These faults indicate that a prameter found during training was out of the expected range.

Try training again. If the fault occurs repeatedly, the PV may need to be replaced.

515, 516 Error Position control fault on port 1 or 2 The mainstage spool did not get close to its demanded position within a specified time window. This can happen if there is insufficient pilot pressure, the control is unstable, or if a spool (pilot or mainstage) is stuck.

Make sure there is enough pressure to move the spools. Check the position vs. the position demand (monitor the debug channels) to see if the spool is unstable (if so, try airbleeding), if the spool is stuck mid-stroke (likely mainstage contamination), or if it is stuck in the center or endstops (possible pilot contamination or electrical problem). If stuck, try to clean/unstick by moving the spool back and forth (try using PWM control).



517, 518 Error Uncontrolled position fault on port 1 or 2

The spool has not returned close to its trained spring neutral position within a specified time window. This can happen if a spool (pilot or mainstage) is stuck, or if the trained null position is incorrect.

Try moving the spool with PWM commands to see if it is stuck or freely moving to both endstops as expected. If moving as expected, try to re-train the valve.

519 Error CV Training failed to acheive a desired pressure in a certain amount of time

During CV training, the spool sweeps through its travel and records the pressure. It needs to reach 90% of the configured maximum pressure before it can complete, so if there is an external pressure limiter (i.e. a relief valve or pressure compensator), training will time-out.

Make sure here are no mechanical pressure limiters st below the configured maximum pressure.

521 Error The spool doesn't appear to be moving during airbleed

The CV spool is not moving during airbleeding.

Make sure there is sufficient pressure to move the spools (supply should be at least 10 bar). If there is sufficient pressure, the spool (mainstage or pilot) may be stuck. Check to see if the mainstage is moving at all, or if it is stationary. If it moves, there may be contamination limiting the stroke of the mainstage spool. If it doesn't move at all, the spool may be fully stuck, or the CV pilot might need to be replaced.

522 Error Pressure controller exceeded an error threshold for a specified amount of time

The Inlet controller was not able to achieve its desired pressure within a specified time window. This can happen if there is a problem with the pump or supply pressure hose. It could also happen if there is a problem with the CV position controller (although this should send a separate fault), if the pressure is limited by a relief/pressure compensator, or if the CV training was not done.

If the pressure control tracking is causing problems, check to make sure the pump and supply/loadsense hoses are correctly connected. If the controller seems unstable, try airbleeding the CV or adjusting the Loadsense hose volume parameter. Try re-training the CV. Note this will be reported if a pressure is commanded from the pump, but it is not spinning.

523 Error Pump margin compared to trained margin differed by a specified percentage

The measured pump margin between supply and loadsense does not match the margin that was recoreded during training.

Check to make sure the pump/hoses are working correctly. If other services are connected to the loadsense line, make sure there is a shuttle-check to isolate them. Try re-training the CV if the Inlet pressure control is causing problems in the system. Note, this fault may be triggered if a pressure is commanded from the pump when it is not spinning.

524-526 Error CV Training faults These faults indicate that a prameter found during training was out of the expected range.

Try training again. If the fault occurs repeatedly, the CV may need to be replaced.

527 Error position control fault (CV) Same as 515/516 for the PV Same as 515/516 for the PV

528, 529 Error pressure control fault WP1 or 2 The pressure controller on the PV did not achieve its desired pressure within a specified time window.

Make sure the hose is properly connected and that the requested pressure is achieveable (i.e. not limited by reliefs). Check to see if the spool is tracking its demand. Make sure the hose volume parameter is close to the actual hose volume.

530, 531 Error Spool Stroke out of range This is a PV training fault, when the detected stroke is either smaller or larger than expected.

Make sure there is at least 10 bar supplied to the valve supply port. If there is sufficent pressure, a spool may be blocked (try airbleeding), or the PV may need to be replaced.

532 Warning Inlet pressure too low to safely control the valve

There is an optional fault that can send a warning if the supply pressure is below a speficied threshold. The pressure setting for this faults is adjusted through the Min Inlet Pressure setting on the PV. If the supply is lower than this setting, the control will be disabled.

This check can be bypassed by setting this parameter to be 0.

533, 534 Error Training exceeded the timeout limit Training is taking longer than expected.

The most likely cause is that small oscillations are causing the PV to not settle sufficiently. Try airbleeding the valve several times. There is also a parameter in the Training section of the OD that specifies the settling tolerance during training (Training Position Theshold Fail) which can be increased.



535 Error Valve failed to find an edge while replacement training was running

This only applies to Pressure or Tank Biased spools. During training, the valve monitors the pressure to detect the edge of the deadband. This fault indicates that an edge wasn't found.

Try training again, ideally with cool oil (but still above 20C). Make sure there is no leakage in the system connected to the valve. If the problem persists, try training with the workports capped.

537, 538, 539 Error Negative pressure reading on supply/loadsense/tank (error)

This is the same as 502, 503 on the PV This is the same as 502, 503 on the PV

540, 541, 542 Warning Negative pressure reading on supply/loadsense/tank (warning)

This is the same as 500, 501 on the PV This is the same as 500, 501 on the PV

543 Error The Fault Handler has gone to a Safe State

The fault handler, which controls the operation of the Limp Modes has set the valve into a safe state. This can happen if multiple sensor faults are detected, or if a single sensor fault is detected but the Limp mode is disabled.

Check to see if there are multiple sensor faults. Also, check the Logged Fault parameter in the Limp Modes section of the PV, if it is not 0-5, then the valve has saved an unknown or multiple fault condition. Try setting it to 0 to see if the detected fault condition is gone. If there are multiple faults, replace the PV.

544 Error Fault Handler is waiting for a Write Finalize command before entering Fail Operational Mode

The valve has detected a sensor fault and is able to enter the Limp Mode, but it is configured to wait for a Write Finalize from the user before doing so.

Send a Write Finalize command or change the Limp Mode Configuration to not require a Write Finalize before entering Limp Modes.

545 Warning Fault Handler has entered Fail Operational Mode

Notification that the valve has entered a Limp Mode

If there is a sensor fault, eventually, the PV should be replaced. However, it should be able to run in Limp Mode. Nothing needs to be done in reaction to this message.

546 Warning Fault Handler has exited Fail Operation Mode and has returned to Normal Operation

Notification that the valve has exited Limp Mode and returned to normal operation

Nothing

547, 548, 549, 550, 551

Error Repeat of the sensor faults (similar to 300-305), reported by the fault handler

Decide whether to remain in Limp Modes, or replace the PV

552 Error Fault Handler is reporting multiple sensor faults

Multiple sensor faults detected, the valve cannot enter Limp Mode

Replace the PV

554 Warning Fault Handler is reporting that it is in Fail Operational Mode but the fault condition is gone

The fault condition is gone, but, due to the Limp Mode Configuration setting, the valve is not allowed to exit the Limp Mode

Write a 0 to the Logged Fault parameter, which saves faults over valve resets, or change the Limp Mode settings to allow automatic exitting of the Limp Mode.

555, 556 Warning WP is in a Pressure limiting state and its consumed flow has dropped below a threshold

This is a stall-detection feature that can be enabled to notify the application that the valve has essentially stopped flowing.

Nothing

557, 558 Warning Consumed Flow on WP has risen above a stall threshold

This message indicates that a previously detected stall condition has dissipated.

Nothing

559 Error Mismatch between input and output flows detected. Possible burst hose.

This is a featuer that can be enabled to detect a significant mismatch in the meter-in and meter-out flows, indicating a possible burst hose.

Check all hoses for leaks.

602 Information A write request was attempted to a (still) protected value

Most Object Dictionary parameters have some level of Write Protection applied to them. Before writing to a protected parameter, the proper Key must be written to the Write Protection index on the VSM.

Write the proper Write Protection key. This key is not saved across resets, so it must be re-sent after every power cycle.

605 Error An invalid Baudrate index was selected

CANOpen only - the parameter setting for the Baudrate is incorrect.

Enter a proper value

606 Error An invalid Node ID index was selected CANOpen only - the parameter setting for the Node ID is incorrect.

Enter a proper value


Problem Possible cause(s) Possible cause(s)

Valve does not respond to demands

1) Anti saturation algorithm is turned on and there is no available flow message

1). Disable anti saturation algorithm or send available flow message

2) CAN Identifier is not correct for the VSM you are trying to communicate with

2). Use ProFx Configure to determine what the VSM address is. If there are multiple VSM’s, the VSM can be identified by the ECU instance number in the name field (refer to J1939 for more details)

3) There are critical errors 3). If there are critical errors, attempt a valve reset (soft or hard). If the errors persist, contact your local Eaton representative.

4) A valve has been replaced and the air bleed and training routine have not been completed

4). Request air bleed through ProFx Configure or implement in the user application. Once the air bleed has been completed successfully, request the valve train. Refer to the Valve Replacement section of this guide for more details.

5) A valve has incorrect firmware version (does not match the other nodes on the system)

5). If a pilot valve replacement is necessary, the pilot valve major version needs to be the same as the major version of the rest of the nodes on the system. The same is true for the object dictionary version. When ordering replacements, please verify what version of software is required.

6) Message transmission rate is slower than the timeout set in the VSM

6). Increase the transmission rate frequency in the application. If appropriate, the mode demand timeout can also be increased on the VSM.

7) Supply voltage is above or below the 9 to 32 volt range 7). The supply voltage can be monitored through a monitor request to the VSM (section index 509). Refer to the Application Developers Guide for more details.

8) Supply pressure is too low to safely control the valve. 8) Supply pressure can be monitored through Pro-FX. Also, a warning message will be sent over the User CAN. This check can be disabled (see section on Minimum Inlet Pressure). However, some pilot pressure is required to move the spools.

9) Incorrect cable assembly 9). Refer to the Technical Catalog for proper wiring of the CMA system.

10) Invalid control mode sent to the valve 10). Refer to the Application Developers Guide and associated tools. The Traffic Monitor in ProFx can be used to debug communication to the valve.

11). There is no pilot pressure or pilot pressure is too low 11). Monitor the supply pressure observed by the Inlet controller. Check system hydraulics.

12). The user CAN bus or the interconnect CAN is not properly terminated.

12). Refer to the Technical Manual. Also make sure the CAN D bus has a terminator fitted.

When multi-servicing, the largest load stops moving

1) The valve is saturating because no anti saturation scheme has been set

1). Select the appropriate anti saturation scheme (ratio, uniform, or cascade).

2) An anti-saturation scheme has been chosen but the available flow message is incorrect

2). The available flow can be monitored through a monitor request to the VSM (section index 60).

3) The transient flow consumption is too high on a particular service 3). Reduce the available flow by adjusting the gain or offset on the VSM. The user could also implement ramps on the demand to limit the rate of change on the flow demand.

The service does not reach the full commanded velocity

1)The flow limit in the valve is too low 1). Increase the flow maximum setting on the valve. Check to make sure the valve is getting the demand as the user expects (make sure to check

2) The valve is entering pressure control 2). Check to make sure the pressure limit is set to what is required by the application

3) The system is entering an anti-saturation scheme 3). Change the anti-saturation scheme to give priority to this service (if that is what is desired)

When using UFC, the meter out pressure drop gets very large

1) The UFC gain on that respective work port is too low 1). Increase the UFC gain

When using UFC and the load passes through the over center condition, the cylinder velocity does not remain constant

1) The UFC gains are too large so that when you transition from a meter in control to a meter out control situation the flow demand is changed

1). Lower the UFC gains and monitor the port pressures throughout the actuator movement. Adjust the UFC gains to achieve desired metering profile.

8. Troubleshooting guide


Problem Possible cause(s) Possible cause(s)

When using IFC, the valve chatters when transitioning from overrunning to passive or vice versa

1).There is instability caused by having too low of a margin pressure 1). Increase the margin pressure

2). The passive and overrunning margin values are too close to each other.

2). Increase the hyteresis loop width on the overrunning and passive margins

3). The IFC pressure controller gains are tuned too high. 3). Detune the IFC pressure controller gains (lower the gains).

When applying small flow demands, the valve moves in and out of its center position causing a jerky feel to the service

1). The flow demand gain is too high from the application. 1). Change the application flow demand gain so that the first 10% of the demand has a very low gain

2). There is no hysteresis applied to the flow demand input device. 2). It is a good idea to apply some demand hysteresis so that the operator can achieve very fine metering

3). Position control on the valve is not working correctly 3). Use the debug channels to see if the valve position is tracking its demand to diagnose a position control problem. Attempt to ‘train’ the position controller for that particular service. Refer to the valve replacement portion of this guide for more detail on training. If this does not improve position control, the pilot valve may need to be replaced. Contact your Eaton representative.

When applying a large flow demand, the service initially starts to move but then stops for a brief period of time, and then motion continues

1). The system could be momentarily saturating. 1). Rate limit the flow demand from the application

2). Supply pressure may not be able to build fast enough or hold margin

2). Tune up the Inlet pressure controller. Refer to the appropriate sections of this document for tuning.

There is too long of a delay from when the demand is given from the application to when the service begins to move

1). The Inlet controller has poor pressure response. 1). Training can be attempted on the Inlet. Refer to the valve replacement section of this manual.

2). The margin pressure across that service is too low. 2). Increase the PV margin. Check to make sure that the CV is achieving the margin as requested from that particular section. This can be doneby monitoring the supply pressure demand (refer to the Application Developers Guide).

As the service is moving through an over center condition, there is a momentary slowdown in actuator speed.

1). One side of the service was oil starved and when the load transitions to the opposite load case the valve has to ‘fill’ that port.

1). The overrunning and passive margins are not set correctly. The load is transitioning to a passive state too late. Increase the passive margin. Be sure the overrunning margin is above the passive margin. If using IFC, make sure the IFC controller is keeping up and maintaining the requested port pressure.

CV will not train

1). The maximum supply pressure setting is above the achievable limit on the pump (comp pressure)

1). Lower the maximum supply pressure setting in the Inlet controller object dictionary.

2). There is no pilot pressure or pilot pressure is too low 2). Monitor the supply pressure and check to make sure the system has at least 15 bar supply. If not, check the pump or the hydraulic configuration.

3.) The valve is not allowed enough time to profile the spool flow/pressure characteristics

3) Increase the timeout value stored in Object Dictionary ID 929 (J1939), found under ‘VD Fault Parameters’

Pilot Valve will not train

1). Train request or train continue message was not received or not received before the valve timeout.

1). If the train request is from PRO FX Configure, avoid moving windows around that could disrupt the train continue message from being sent.

2). If the valve finds a fault during training, it will display a message over the User CAN.

2). Depending on the fault found, it may be over ridden using the fault masks (described in further detail below). If it is a fault that cannot be over ridden, a new pilot may be necessary. Note that training is not allowed unless the measured temperature is over 20C.

The service oscillates when in motion. 1). There is an interaction with load, valve, and/or pump

1). Try adjusting the Flow Demand Shaping parameters to avoid exciting resonant modes. Reduce the Q Demand Shaper gain to move the bandwidth slower than service resonant modes

2). Adjust the Pressure Damped Flow Control gains and/or the workport volume setting

3). Reduce the responsiveness of the pump to rising or falling (or both) pressure demands using the Rate of Change Limits.

4). Make sure the Line Loss Pressure Compensation gains are not too high.


9. Configure 2.0 Routines


Before commencing, ensure that the individual performing the service has the appropriate user credentials to request an Airbleed and Train of the Pilot Valve being replaced .



• Personal Computer with minimum requirements of operating system of Windows 7, 8, or 8 .1; 1Ghz processor; 512 GB of RAM; 4 .6 GB of disk space; screen resolution of 1366x768

• Pro-FX Configure 2 .0

• Supported CAN card (Softing USB, Softing CANPro USB, Kvaser CAN card)

• A cable for connecting the computer with Pro-FX Configure to the CMA valve (either through the machine's CAN network or directly to CMA)


4. Select the appropriate communication protocol of the CMA valve that will be serviced (J1939 or CANOpen) (1). Press “Next” (2) to continue.


9.1 Connect to CMA Procedure


• These steps must be done before the majority of the subse-quent routines in this section .

Procedure:

1. Connect the computer with Pro-FX Configure 2.0 to CMA either through the machine’s CAN network or directly

2. Turn on electrical power to CMA

3. Double click on the Pro-FX Configure 2.0 icon to launch the program. Note that the program has to be launched from this icon and not from the application in the Start Menu.


6. The Detected Components screen will display the various valves that make up the connected CMA valve. If the valves displayed do not match the actual valves connected (for example, CMA has 4 sections but only 3 are displayed), diagnostics will have to be performed to determine the problem. Proceed to troubleshooting section. If valves displayed match the valves connected, then press Next (1) to proceed.

7. Pro-FX Configure is now connected to CMA. Proceed with Service routines as necessary.


2. Scroll Down to “J1939 Preferred Address” (1). Change the value to the desired address then press “Save to Device” (2).

9.2 Change Default J1939 Address

3. Close and reopen Pro-FX Configure 2.0 to connect to the new CMA valve’s address.


• The steps in “Connect to CMA” must be completed before starting this routine .

Procedure:

1. Navigate to the VSM’s Communication tab (1).


9.3 Change Default CANOpen NodeID

2. Change the value of “Node ID” (1) to the desired Node ID then press “Save to Device” (2).

3. Close and reopen Pro-FX Configure 2.0 to connect to the new CMA valve’s Node ID.



Procedure:

1. Navigate to the VSM’s Communication tab (1).


2. On the menu, go to “File” and click “Save Parameters From All Devices To File..."

9.4 Export Backup of CMA



• It is good practice to export a backup of the CMA valve to be serviced prior to beginning any service routines .

• Export takes a backup of all parameters from all valves on the connected CMA .

Procedure:

1. Press the menu button (1) to expand the menu.


4. The busy indicator will be visible while the export is in process. This may take several minutes (approximately 20 seconds + 20 seconds for every work service in the

system).

3. Navigate to where the file should be saved and enter a file name. Press “Save”.


5. After the export is complete, a popup box will be displayed to notify the user.


9.5 Import Backup of CMA



• Load Application Parameters To All Devices From File will import all non-calibration parameters for all valves available in the backup file to CMA .

• Load Application and Calibration Parameters To All Devices From File will import all parameters (even calibration) for all valves available in the backup file to CMA . Import Advanced should only be performed by trained individuals or as recom-mended by Eaton engineering .

• Both loading options check to make sure the OD version of the backup file match the connected CMA valve prior to completing the import .

• Procedure:

1. Press the menu button (1) to expand the menu.


2. There are two ways to import and it is very important to pick the correct one:

a. Load Application Parameters To All Devices From File: To be used when only machine-specific parameters (such as cylinder areas, max pressures/flows, etc.) are to be imported from the backup file. This feature will not import valve-specific calibration data which was calibrated in the factory. For example: if the tuned parameters (cylinder areas, max pressure, max flow, etc.) from one machine are to be copied to another machine, Import would be used so that the calibration parameters from the first machine’s CMA valve are not copied to the second CMA

valve.

b. Load Application and Calibration Parameters To All Devices From File: To be used when all the parameters (even valve-specific factory calibration data) are to be imported from the backup file. For example: if the calibra-tion parameters have been corrupted due to an improp-erly performed PV replacement, Import Advanced would allow for a previously taken backup of this CMA valve to correct the corrupted parameters. This feature should only be used by a trained technician or someone under the guidance of Eaton engineering.

3. Select the backup file to be imported. Press “Open”.


5. Press “Save to Device” (1) to save the imported parame-ters to CMA.

4. After the import is completed, a pop up box will notify the user that the data have been loaded into ProFX Configure® and are ready to be saved to the CMA valve

system. NOTE: the data must be saved to the device before closing Pro-FX Configure or navigating to another section of CMA.


9.6 Airbleeding



• During airbleeding of work sections, CMA will control the supply pressure to 30bar .

• During airbleeding of the inlet, supply pressure will oscillate between tank and full system pressure .

• The prime mover must be “On” and supplying hydraulic power .

• Airbleeding moves the pilot spools back and forth in order to remove air from the pilot cavities .

• When the pilot spools are cycled, the main stage spools also cycle from fully open to supply to fully open to tank simulta-neously (i .e . both open to Pressure, then both open to Tank) at approximately 5 Hz . As a result, the work port will oscillate between tank and 30 bar pressure .

• Airbleeding typically lasts about 3 minutes .

• If a PV or CV has been replaced, CMA will require airbleeding prior to operation .

• If the inlet (CV) and a work section (PV) both are requiring airbleeding, the inlet (CV) must be airbled before the work section (PV) is airbled .

• Multiple work sections can be airbled at the same time .

• The user can also request airbleeding at any time .

Procedure:

1. Press the “Airbleed” button (1) to expand the airbleeding menu.


2. If CMA is requiring a valve be airbled, it will be checked. If the user would like to also airbleed another valve, it can also be checked. Press “Airbleed” to airbleed the checked

valves.

3. Ensure that the machine is in a safe state for the work ports to be opened to tank and 30bar pressure. Press “Continue” to proceed to airbleed.


4. While airbleeding is in process, the busy indicator will be displayed. Note that if a work section is being airbled, the main inlet will also so as in process because it will be controlling supply pressure to 30bar. If airbleeding needs to be discontinued, the “Stop Operation” button can be

pressed.

5. After airbleeding is completed, the status will show as either Finished Successfully or Finished Unsuccessfully.


9.7 Training



• During work section training, CMA will control the supply pressure to 30bar .

• During inlet training, CMA will ramp supply pressure from tank to full system pressure

• The prime mover must be “On” and supplying hydraulic power .

• Training moves the pilot and main stage spools back and forth sequentially (Spool A first, then Spool B) through the complete stroke to learn characteristic information .

• When the main stage spools are cycled from fully open to supply to fully open to tank, the work port will be opened to tank and 30 bar pressure . As the spools are trained sequen-tially, while spool A is moving between end-stop to end-stop, spool B will remain the spring-biased condition and vice-versa .

• Training typically lasts about 2 minutes .

• If a PV or CV has been replaced, CMA will require training prior to operation .

• If the inlet and a work section both are requiring training, the inlet must be trained before the work section is trained .

• Before training the inlet, the inlet’s Maximum Pressure must be set to an achievable pressure (usually a bit lower than the inlet or system relief) . The inlet LS volume must also be set for Variable Displacement pumps

• Multiple work sections can be trained at the same time .

• The user can also request training at any time .

• If any of the work-section spools are spring-biased to Supply and the downstream service can consume enough flow to saturate the pump, steps must be taken to prevent this (such as installing a shut-off valve and plugging the work-port .


2. If CMA is requiring a valve be trained, it will be checked. If the user would also like to train another valve, it can

also be checked. Press “Train” to train the checked valves.

• Procedure:

1. Press the “Train” button (1) to expand the airbleeding menu.


3. Ensure that the machine is in a safe state for the work ports to be opened to tank and 30bar pressure. Press

“Continue” to proceed to training.

4. While training is in process, the busy indicator will be displayed. Note that if a work section is being trained, the inlet will also be shown as being in process because it’s

being used to control supply pressure to 30bar. If training needs to be discontinued, the “Stop Operation” button can be pressed.


5. After training is completed, the status will show as either Finished Successfully or Finished Unsuccessfully.



Before starting an update, make sure that no other devices on the machine are sending commands to CMA .


• The desired software may have to be downloaded from PowerSource .

• Pro-FX Configure 2 .0 will take care of moving parameters to their new locations, if necessary .

• The general process Pro-FX Configure 2 .0 will complete includes: backing up the valve, flashing new software, loading all the new parameters with default values, and moving parameters from their old location to their new locations .

Procedure:

1a. To update the firmware of all the work sections, inlet, and VSM, in the menu at the top right, click Update Firmware (1a).

1b. To update the firmware of an individual device, navigate to that device's Info tab and click Update Firmware of This Device (1b).

9.8 Software Upgrade


2. Select the update file for the software to be loaded to the valve. Then press continue.

3. During the update process, a progress bar will display the current progress. Additionally each step in the process will be checked off as it is completed.

4. After completion, the user is given an option to save the backup file taken with the old software version to a permanent location. Select the desired option and press close. The update process is now complete.

5. If the update process was interrupted, restart the update process. Pro-FX Configure 2.0 will identify that a previous update process was not completed and ask if it should be continued.


9.9 Monitor Valve Data Using Data Plot


• The following procedure is only available for users with Configuration access . Dataplotting is not available for Service only users .


Procedure:

1. Open the DataPlot window (1).


2. Press the Configuration button (1) to select the signals to data plot.

3. Select the signals that are desired to data plot. Note that the units for the signal can be changed, if applicable.


4. Press OK to go back to the data plot window.

5. Each signal will have its own y-axis on the data plot window.

6. Press the “play” button (1) to start collecting data and the “pause” (2) button to pause the collection of data. If the user presses “play” again, data collection will resume in the existing trace. If the user presses “clear” (3) then presses play, the screen will be cleared and a new trace will begin.


7. The scroll bar at the bottom (1) will display a small view of the first signal collected. It also shows the data that is currently viewable within the two squares (2). This can be used to move quickly to a point in time where a specific event occurred in the first data trace. The squares can be spread apart or pulled together to zoom out or in.

8. The y-axes will automatically scale to the data that is being collected. However, they can be scaled by clicking at either end of the axis and dragging up or down to zoom as desired. The y-axes can be reset to the collected data by pressing “reset y” (1).


9. When paused, specific values of the data can be viewed by turning inspection on (1) and hovering over a data trace.

10. If the user would like to inspect data without pausing data collection, “follow” (1) can be turned off and the viewer will stop following the newly collected data. Inspection can then be turned on and data can be inspected. After inspection is completed, following can be turned back on to start viewing the newest data.


11. Data can be exported to a .csv file by pressing “export” (1).


12. If not controlling CMA with Pro-FX Configure 2.0, the controls pane can be minimized by pressing the “<” (1). It can then again be maximized by pressing “>” (2).
