CV - 110 / 116 Description


1 DescriptionThe vibration monitoring system VIBROCONTROL 1000 series C,comprising the electronic system and the vibration velocity transducer VS - ...

is used for measuring and monitoring absolute bearing vibrations.The vibration transducer converts the vibrations occuring at the be-aring housing into electric signals. These electric signals are supp-lied to the measuring and monitoring electronics.The electronic system can either generate the effective value of vibration velocity (veff) or the peak value of vibration displacement (sp)comparing either of these values with 2 preset limit values. If theselimit values are exceeded the respective alarm relays are tripped.Via the potential-free relay contacts warnings (pre-alarm) or thedisconnection of the machine (master alarm) can be triggered.

The instruments types CV-110 and CV-116 only differ in thepower supply voltage.CV-110 requires a power supply voltage of 230 V AC,CV-116 requires a power supply voltage of 24 V DC.

3 Commissioning

Adhere to attached safety instructions !

3.1 InstallationRemove housing cover and fix the base part by using 4 Phillipshead screws M6.Any installation position is accepted!Replace unused conduit threads replaced by sealed metallic pegsto ensure type protection IP 65 and EMC.

Figure 4 Dimensions

Commissioning CV - 110 / 116


3.2 Connections for instrument type CV-110Removal of the housing enables access to the connectionterminals.

Figure 5 Connection terminal diagram(The relay contacts are shown in de-energized condition)



3.3 Connections for instrument type CV-116Removal of the housing enables access to the connectionterminals.

Figure 6 Connection terminal diagram(The relay contacts are shown in de-energized condition)



Note:This chapter describes the connectiion terminals of CV-110 andCV-116. Possibly necessary changes of the device setting aredescribed in the Service chapter.

Protective conductorThe protective conductor PE of the mains supply cable must beconnected to earthing point 1 inside the housing (cf. fig. 7). Use theforked terminal which is already fixed at earthing point 1.

EMCThe external grounding screw (cf. fig. 7) must be grounded with theshortest possible length of cable having a minimum crosssctionalarea of at least 2,5 mm2.

Figure 7 Position of the grounding points (arrows)



ScreeningAll cables connected to the electronic system must be screened!

There are two different cases: The screen of the transducer cable must be passed through

the PG-screwed connection and is to connect with earthingpoint 1.Use the forked terminal which is already fixed atearthing point.

The screens of all the other cables must be connected with thecorresponding PG-screwed connection (cf. fig 8).

Figure 8 Connecting the cable screen to the conduit thread



3.4 Alarm relayIf the limit values are exceeded the corresponding alarm relaysrespond time-delayed, via the potential-free change-over contactsby means of which a warning signal or the disconnection of themachine can be triggered.

3.4.1 What you should know about alarm relaysTwo switching variants are possible: Normally de-energized

If the limit values are not exceeded (OK) the coil of the relay isde-energized, however, if the limit values are exceeded (alarm)the coil is current-carrying, the relay is energized.

Normally energizedIf the limit values are not exceeded (OK) the coil of the relay iscurrent-carrying, if the limit values are exceeded (alarm) thecoil is de-energized, the relay is released.

The desired variant is determined by jumpers (cf. 5.1).

Figure 9 Limit value relayThe contacts are shown in dead condition

2 modes of operation are possible: latching non-latching

The adjusted mode of operation is stated on the information sheetinside of the housing.



3.4.2 Reset (acknowledging of relay messages)Latching alarm relays must be reset after an alarm message has been given orswitching on the monitoring electronics

The jumper installed between terminal 14 and 15 causes a"permanent reset".If required, the jumper can be removed and be replaced by anexternal reset pushbutton which bridges the terminals 14 and 15only upon actuation of same (cf. fig.5 and 6).Connect the reset button with screened line only!

3.4.3 Setting limit valuesThe limit values of both alarm relays are determined by means ofthe two potentiometers LIM 1 and LIM 2. The setting is performedin % related to the adjusted full scale value.

Example:Requirement Pre-alarm at 10 mm/s

Main alarm at 14 mm/sSetting Measuring range: 20 mm/s (= 100 %)

Pre-alarm: Potentiometer LIM110 mm/s = 50 %Main alarm: Potentiometer LIM214 mm/s = 70 %

Figure 10 Alarm potentiometer



3.5 OK relay (self-monitoring)By means of an integrated self-monitoring system interruptions inthe transducer system or the signal line as well as the failure ofmains voltage are signalled.The message is effected without response delay via the OK-relay.

The OK-relay is always Normally energized and Non-latching

Upon connection of the measuring and monitoring electronics andafter the elimination of all malfunctions the OK-relay switchesautomatically from "ALARM" to "OK" (reset is not necessary).Limit value messages are not influenced by the self-monitoringunit.

3.6 Readiness for operationIf all connections and adjustments have been carried out properly,the mains voltage can be applied; the OK-relay is energized and isswitched to "OK".For latching alarm relays the external reset pushbutton must beactuated - no alarm signal must be available!

During the accelleration phase the machine might reach vibrationvalues that exceed the limit values (e.g. passing the resonance).To avoid that the machine is disconnected during this phase theshut down system coupled with the monitoring electronics can beblocked until the operational speed is reached.

Upon reaching of the working order: actuate the reset pushbutton reactivate shut-down system

CV - 110 / 116 Explosion protection


4 Explosion protectionBy means of vibration monitoring system VIBROCONTROL 1000,series C, one can also monitor machines in hazardous areas.

The electronics must be installed outside thehazardous area !!!

When installing an explosion-proofed transducer a back-up fuse inthe measuring electronics is mandatory. If - according to the ordercode - the electronic system is designed for the connection of avibration transducer with explosion protection the required fuse willalready be integrated in the factory.Solder fuses F101, F102Explosion protection 2 x 15 mA, qiuck-blow

Figure 11 Position of the fuses F101 and F102

It is within the responsibility of the user to make sure that theinstallation is effected in accordance with the local regulation andthe local acceptance authorities.

For further information please refer to the connecting diagram (fig.5 and 6) and the description of the transducer.

5 Service

Adhere to attached safety instructions!

5.1 Changing settingsDe-energize the electronic system before opening thehousing!

Basic adjustments must not be changed but by authorized servicepersonnel only !!! Unauthorized adjustments are forbidden!The adjustments of the electronic system can be changed bydifferent jumpers, which are accessable after the housing coverhas beeen removed (cf. fig. 12).The following adjustments are possible: Measured variable

Vibration velocity Vibration displacement

Frequency range (with/without linearization) Measuring range Mode of the alarm relays

Normally energized or normally de- energized Latching or non-latching Delay

Analog output current 0 ... 20 mA 4 ... 20 mA

The measuring and monitoring electronics have been set and test-ed according to the details given in your order.The setting data are defined on insert sheet "Ordering code/devicesetting". The insert sheet is contained in the housing.If the device setting is other than standard, you will find the settingdata under the heading of "Factory setting". For your own safetyyou should write down each change of the setting data togetherwith the serial no. in the insert sheet.

5.2 Trouble shootingIf the OK-relay signals a malfunction, proper functioning of themonitoring system cannot be guaranteed any longer.We recommend to perform the following tests:

1. Checking voltage supplyfor instrument type CV-110

Deenergize the instrument! required voltage at the mains terminals? Power supply transformer thermal fuse has opened?

Wait until the power supply transformer has cooled off.If upon retrying to switch the instrument on the fuse againopens, then the instrument should be sent to an authorisedservice centre and checked.

2. Checking voltage supplyfor instrument type CV-110

Deenergize the instrument! required voltage at the mains terminals Power supply fuse F403 ok?

3. Checking the transducer connection are the terminal connections of the signal line ok?

is the terminal protective housing - if existent - installedcorrectly?

cable fracture in the signal line or winding fracture in thetransducer?

The self-monitoring unit only reacts if the signal circuit isinterrupted; by bridging the signal input (terminals 2 and 3) properworking order can be simulatedIf this jumper is positioned e.g. at the terminal protective housing,the source of malfunction can be determined much faster.

The self-monitoring unit does not detect a short-circuit occured inthe transducer/transducer connection.

However, despite the existing vibration level, the following valuescan be measured at the analog outputs:Analog output 0 ... 10 V: 0 V

0 ... 20 mA: 0 mA4 ... 20 mA: 4 mA

If these measures are not suited to eliminate this malfunction, theelectronic system together with the transducer have to be returnedfor repair.Further trouble shooting "on site" can be performed by authorizedservice personnel only.

Advantages and disadvantages of 24 VDC operation with theCV-110 resp. CV-116

24 V DC connection to CV-116

AdvantagesThe instrument has a DC/DC converter. Therefore the potentialfreedom of the power voltage is guaranteed. This makes theanalog outputs also potential free.A further advantage is in the large tolerance range for the 24 Vpower supply (18 36 VDC)In addition, with this connection maintenance of the EMV guidelinesof the manufacturer are also guaranteed

24 V DC connection to CV-110

DisadvantagesUnder certain prerequisites the CV-110 can be operated with 24 VDC. When connecting the 24 V DC the following conditions mustbe met:1. For such a connection the operator must guarantee mainte-

nance of the EMV guidelines2 The inputs and outputs are not potential-free; i.e. the 0 volt

terminal of the analog output is always at the same potentialas the 0 V of the operating power!

3. The tolerance range of the power supply is limited to +24 VDC -20 % +10 %

4. Any disturbance on the 24 V power supply will directly affectthe measurement electronics

Note:The 24 V DC input is protected by a 0,5 A fuse.

3.1 Attaching the sensor

The following applies on principle: Mounting surface flat and clean, i.e. without paint, rust etc Threaded stud perpendicular to mounting surface; the trans-

ducer must be tightened to the mounting surface Secure stud with LOCTITE

(e.g. LOCTITE 243 medium-duty, LOCTITE 270 heavy-duty) Avoid auxiliary fixtures for mounting;if unavoidable, the fixture

should be as rigid as possible For protection against mechanical damage and for increase

EMC safety the connection cable should be laid in flexible steelprotective conduit. Bending radius rmin = 50 mm

Tighten transducer directly to mounting surfaceMax. tightening torque 87 Nm



3.2 Preparing the steel protective conduitAdapt the steel protective conduit to the site conditions by takingthe following steps: If the protective conduit has a braided shield, to ensure a clean

cut through the braided wrap a strip of metallised adhesivetape around the area where the cut is to be made beforestarting the cut.

Cut the protective conduit with a suitable cutting tool, e.g.metal saw, cutting disc.

De-burr the cut end.



3.3 Mounting steel protective hose at VS-068 / 069 / 077

To achleve the optimum shielding performance of AC-331according VDE 0245 and DIN 47250 part 4, the protectiveconduit with connector should be assembled as follows:

Cut protective conduit to appropriate length (see 3.2). Disassemble connector and slide pressure screw (long

version) over the conduit. Slide sealing ring over the conduit with tapered edge facing the

pressure screw. Uncover the outer jacket of the conduit with care leaving a

section as long as 1.5 x the width of the brass-thrust collar. Cut copper shield with scissors flush with the conduit. Slide brass-thrust collar (with taper side as shown) over the

conduit as illustrated above. Screw brass ferrule into the conduit until it stops. Assemble the rest of the individual components and tighten so

that the O-ring is not movable. For liquid-tight installations install the additional O-ring at the

connector thread side.



3.4 Fixing steel protective conduit at VS-079

Cut protective conduit to appropriate length (see 3.2) Slide the union nut and sealing ring on steel protective hose

behind the cutting point Screw the inner tube onto the steel protective conduit Slide steel protective hose slide over transducer cable and fix

protective hose joint to the transducer and the steel protectivehose
