4 Description / Intended Use AP - 0 Description / Intended Use The vibration monitoring system VIBROCONTROL 000, series A, comprising the Electronics and non-contact displacement sensors is used for measuring and monitoring the relative shaft vibrations. Axial displacement of a rotor from preset zero position is picked up by noncontact displacement sensors and are converted into electrical signals. The measuring and monitoring electronics form the shaft displacement s (mm) equidistant and with correct sign. AP0AUF (96045) Figure ) Measuring of the relative shaft vibrations The electronics compares either of these values with 4 settable limit values, i.e. two limit values each for negative and positive displacement. If these limit values are exceeded the respective alarm relays are switched. Warnings (pre-alarm) or machine shut-down (main alarm) can be released via the potential-free relay contacts.

12 Commissioning AP Alarm relay Two freely selectable limit values are available for each direction of measurement (positive and negative) LIM - LIM - LIM+ LIM+ 0 Zero position The green LED is lit with 0 position. X If the limit values are exceeded the respective alarm relays respond with time delay. Their potential-free change-over contacts enable release of a warning or shut-down of the monitored machine What you should know about alarm relays Two switching variants are available: Normally de-energized The relay coil is dead with non-exceeded limit value (OK), it is life when the limit value (alarm) is exceeded - the relay is energized. Normally energized The relay coil is life with non-exceeded limit value (OK), it is dead when the limit value (alarm) is exceeded - the relay is released. Set the desired variant by using soldering jumpers (see connection terminal diagram Figure 4)). AP0E / C / V 05 / 3/03/06 Page / 6

Two modes of operation are possible: latching non-latching The required mode of operation is set by means of jumpers (see connection terminal diagram Figure 4)) Reset (acknowledgement of relay messages) Latching alarm relays must be reset after an alarm message has been given or switching on the monitoring electronics. The jumper between terminals 40 and 4 effects "permanent reset". If required, this jumper may be removed and be replaced by an external reset button that will bridge terminals 40 and 4 only when actuated (see Figure 4)).

15 AP - 0 Commissioning 3.5 OK relay (self-monitoring) Integrated self-monitoring signals short circuit/interruption of input circuit wrong distance of the sensor to the measuring track failure of the supply voltage The message is given without delay via the OK relay. The OK relay is always Normally energized and Non-latching Upon connection of the measuring and monitoring electronics after the elimination of functional errors, the OK relay automatically changes from "Alarm" back to "OK" (Reset is not required). 3.6 Readiness for operation Alarm messages are not influenced by self-monitoring. Energize the voltage supply after having provided for all connections and settings; the OK relay is energized and switched to "OK". With self-latching alarm relays, actuate the external reset button - no alarm must be pending! During acceleration the machine might reach vibration values that exceed the limit values (e.g. passing resonance value). If the alarm delay time is not sufficient to enable a resonance condition to be run through, then the corresponding limit value relays will be activated with consequental machine shut-down. To avoide this condition, the relay activation must be over-riden. Upon reaching working condition: Actuate reset button Reactivate shut-down system Page 4 / 6 AP0E / C / V 05 / 3/03/06

See para The LED V7 is meant to be an adjustment tool for displacement sensors.

23 AP - 0 Service Example: The input resistance has to be checked after a change of the measuring range from -0.5 mm mm. Input resistance 8 mv/µm corresponding to 8 V/mm. A measured displacement of ± 0,5 mm thus corresponds to an input voltage of ± 4 V. Our example shows a symmetrical setting with zero at -0 V DC (standard setting). You require a rise of the output signal at increasing gap width (see para ). Input voltage Analog output Measured displacement - 6 V DC 0 V DC mm -0 V DC + 5 V DC ± 0 mm -4 V DC + 0 V DC mm Rising output signal A voltage deviation at the analog output must be readjusted via potentiometer R8. (See Figure )) Rising of the output signal can optionally be achieved with increasing gap width decreasing gap width Selection is done by inserting/removing a wire jumper between soldering points X6 and X7. Rising output signal with: Open soldered points Jumpered soldered points increasing gap width decreasing gap width The soldered points are to be found on base panel CVC Y 004 (see Figure ). Column width definition Increasing column width: Input voltage U E = - V corresponds to recorder output R A = 0 V Input voltage U E = -8 V corresponds to recorder output R A = 0 V Decreasing column width: Input voltage U E = - V corresponds to recorder output R A = 0 V Input voltage U E = -8 V corresponds to recorder output R A = 0 V Page / 6 AP0E / C / V 05 / 3/03/06
