2.2 Changing the factory settings
To change the factory settings, proceed as follows:
D Loosen the four screws at the back of the housing.
D Carefully extract the back panel of the housing backward, with themotherboard attached, until the jumper arrangement is accessible. You canplace a screwdriver between the connection board and the housing andlever out the back panel.
D By following the diagram, change whichever setting is relevant to you withthe aid of the jumpers.
2.2.1 Setting the analogue output signalTo make the analogue output signal setting (voltage or current), use jumpersST11. Choose between 20 mA or 4 ... 20 mA in the control dialogue.
2.2.2 Choosing the operating mode for synchronization
To synchronize several devices, set one device as the Master. All the otherdevices should then set to Slave. To make the Master and Slaveselections, use jumpers ST13, ST14 and ST15.
2.2.3 Replacing the fusesTo replace the fuse, remove the back panel of the housing as described. Thefuse (230 V/100 mA; 115 V/200 mA) will then be accessible on themotherboard (see Fig. 2.1).

Fig. 3.6: Output assignments
The control inputs and outputs are available at the terminal strip socket(9pin) and are potentialseparated by optical couplers.* The control outputs and inputs must be supplied with an external voltage
(ground and 24 V).
NOTEWhen the mains voltage is disconnected or fails and when the mainsfuse blows, all the control outputs are set to 0 V (Vext.).
3.5 Synchronization
If several devices are used right next to one another or if their cables run par-allel, the devices should be synchronized. To achieve this, one device is set toMaster and all the others (max. seven) to Slave. The setup with jumpers onthe amplifier motherboard is described in Chapter 2.1. As well as these set-tings, the devices must be linked together for synchronization.

3.6 Setting the reading angle of the display
Depending on the mounting position, it may be possible to adjust the readingangle. A potentiometer is used for this limited adjustment. The potentiometeris located behind the keyboard under the display. To set a new viewing angle,proceed as follows:
D Remove the plastic frame of the display from the housing.
D Carefully lever out the keyboard (e.g. with the aid of a screwdriver).
D Use a screwdriver to turn the potentiometer and set the optimum readingangle.
D Put back the keyboard. Make sure that the plug is correctly threaded at thebottom edge of the keyboard. Quickly test the keyboard by pressing a key.If it functions correctly, you can continue.
D Insert and tighten the fastening screws.
D Push the plastic frame back on the housing.
3.7 Connecting the serial interface
PK232-interface:
On the back of the device, there is anRS232 or RS485 serialinterface for connecting a computer or a terminal. ThePK485-interface is brought out at sockets Bu2 and Bu3.
When connecting a printer, a simple line printer needing nomore than 4 seconds to print a line is sufficient. The printouthas 12 columns. This corresponds to a line length of 132characters. Select the measured values to be printed asdescribed in Chapter 4.4.11.
When connecting a computer, it is possible to enter into dialogue with theMVD2555. You can use control commands to make all the device settings andquery the measured values. An overview of the interface commands has beencompiled in another part of the Operating Manual Operating the MVD2555by computer .

4 Setting up and operation
4.1 Commissioning and factory settings
Some of the steps you need to take to commission your measurement chain(panelframe amplifier and transducer) are listed below, so that you can carryout an initial function test of all components. The description basically coversadapting the MVD2555 to the transducer type to be used. We also warn aboutcertain errors which can typically occur during commissioning.
D Follow the steps given in the previous chapter to connect the mains cableand the transducer to the measuring amplifier.
Please observe the safety instructions!
D Turn on the power switch.
D The device runs a function test and is then in measuring mode. Durationof the function test: 1.5 s (if autocalibration is enabled, approx. 2.5 s).During the function test, the warning output stays at 0 V. The factorysettings are active.
D Check the choice of output signal shown on the display. Use to select
the gross signal (no labelling in the display).
NOTEIf the error message CALERR. appears here, this can have the followingcauses:
No sixwire feedback connected
Incorrect transducer/sensor connection
No transducer/sensor connected
Remedy:Switch off the device. Connect the transducer properly. Switch the de-vice back on.

HBMA0104-5.3 en
NOTEIf the error message OVFL B, OVFL N, appears, you must adjust theamplifier for your type of transducer. The steps to take for each amplifierare described below.
D To get from measuring mode to device setup mode, press SET for about2 s. DIALOG will appear in the display.

The current device amplifier settings can be saved power fail safe in eightparameter sets and later queried.When switching from the programming operating mode to measuring mode,you will be asked whether or not the change is to be saved. This is describedin Chapter 4.4.3 .
You can also use remotes (PARACODE1 ... 2, see Chapter 4.5.8 ) toActivate/Load parameter sets.
RECALL: Parameter set 1 (parameter set 1 ... 8) and the factory setting(FACT. SETUP) are loaded
SAVE: Save as parameter set 1 ... 8

EXCITATION:The excitation voltage for the transducer is selected.
Selectable excitation voltages 1 V 2.5 V
INPUT:Depending on which excitation voltage is chosen, the input range(approximate measuring range) can be selected for the transducer type.

AUTOCAL:Depending on the application and on the stability requirement, you can startan autocalibration cycle. This lets you correct zero point and full scale valuedrift and the longterm constancy of the measuring amplifier.Possible settings:
ON Autocalibration switched on
OFF Autocalibration switched off
ONCE Autocalibration is run once, as soon as you confirm it with. Autocalibration stays on/off, depending on the state
previously selected.
CAUTIONIf you need the analogue output signal for continuous monitoring, youmust switch autocalibration off. Reason: during the autocalibration cycle, no measured values arerecorded. This produces a monitoring gap (interval approx. 5 min.,duration approx. 1 s), which is undesirable if not dangerous duringproduction processes.

5 Example
The following example uses a measurement task to show you the functionalityof the device and the required settings.
Problem definition:The forming process in a press is to be monitored in order to obtain uniformproduct quality. The maximum force exerted by the press is to be recorded ineach cycle. To guarantee the production process, this maximum force mustfall between the lower (F1) and upper (F2) force limit.
Solution:The force characteristic measured with an S.G. force transducer (e.g.C9B/10 kN; 1 mV/V) is amplified and evaluated by the MVD2555. The peakvalue store (maximum) is used to record the maximum force and it isevaluated with two limit switches with regard to the lower and upper limits. Anadditional limit switch is provided for overload protection (emergency shutdown) of the machine.A PLC takes over the control of the process. As well as the control commandsfor the press, it gives the MVD2555 a start signal to begin the pressing cycleand once the process has finished, logically links the limit switch outputs tothe Good/Bad evaluation.The start signal from the PLC clears the contents of the peak value storethrough the MVD2555 control input. To prevent unintentional modifications,during measurement, only the Display signal selection button is enabled forthe machine operator on site.The parameter setups are protected against unauthorized modification by apassword.Device control through the remotes (remote control) must be activated.

Limit2 Checks whether the upper force limit has been reached.The input signal is the output of the peak value store(maximum value). If limit LV2 is exceeded, a Low signal isgenerated. A positive switch direction must be set withpositive output logic.
LV3 Checks whether the maximum load limit of the machine isexceeded (emergency shutdown function). The input signalis the gross measured value. If limit LV3 is exceeded, aHigh signal is generated. A positive switch direction mustbe set with positive output logic.
PVS1 Records the maximum peak value of the forcecharacteristic. Must be enabled, the envelope function mustbe deactivated. The input signal is the gross measuredvalue. PVS1 is cleared with remote 1 by switching toinstantaneous value.

CAL.ERR Incorrect transducer/sensorconnection:
No transducer/sensorconnected
