Product description Electrical connection Mounted into - carrier BGT 596 Ex 33-pole multipoint connector, series F (d, b, z) with coding holes screw terminal, max. for 1.5 mm2 - in housing type 505 Ex CE conformity VEGATOR 537 Ex signal conditioning instruments meet the protective regulations of EMC (89/336/EWG) and NSR (73/23/EWG). Conformity has been judged acc. to the following standards: EMC Emission EN 50 081 - 1: 1993 Susceptibility EN 50 082 - 2: 1995 NSR EN 61 010 - 1: 1993 1.
Mounting 2 Mounting VEGATOR can be either installed with a module into a carrier BGT 596 or a single housing type 505. Mounting single housing Module (33) for VEGATOR 537 Multipoint connector DIN 41 612, series F, 33-pole (d, b, z) with coded pin and material for mounting into carrier BGT 596. You can either screw the socket directly onto the mounting plate or plug it onto the carrying rail (TS 35 x 7.5 acc. to EN 50 022 or TS 32 acc. to EN 50 035). Connect the terminals to the basic board acc.
Mounting Coding Ex version The multipoint connector of the instrument is provided with one or more coding holes to prevent incorrect module insertion. Ex separating chamber An Ex separating chamber must be mounted to the connections of VEGATOR to ensure sufficient "air and creep distances". Feed the cables through the Ex separating chamber and connect them. Fasten the Ex separating chamber with the lower retaining screw. Note the operating instructions of the carrier BGT 596.
Electrical connection 3 Electrical connection Danger Switch off the power supply before starting connection work. Connect mains voltage acc. to the following connection diagram.

Setup Green - operating control lamp (9) - mains voltage On, instrument in operation. Red - signal lamps (5 and 8) - failure of the respective sensor circuit through sensor failure or line defect. - when the fail safe relay deenergises, the red control lamp lights. Yellow - relay control lamp (4 and 7) - the yellow control lamps react according to the adjusted mode (A/B). - the relay control lamps indicate the energised condition of the relay.
Setup Min./Max. mode The min./max. switch (12) is used for linking both sensor inputs to one common min./max. signal. With it, you can create a pump controls system. Switch off on Output relay 2 cannot be used for pump control. It has the following function: Sensor uncovered – relay 2 energised, Sensor covered – relay 2 deenergised. Double point control Measuring system for detection of two levels (alternating function), e.g. pump control.
Setup Test key In systems with two-wire oscillators (VIB E50 Z (Ex), SW E60ZEx, SW E82ZEx) a function test can be carried out. VEGATOR 536 Ex signal conditioning instrument is equipped with an integrated test key. The test key is set lowered into the front plate of the signal conditioning instruments. Press the test key with a suitable object (screwdriver, pen etc.). If VEGASWING is connected to a VEGALOG processing system or a PLC, you have to interrupt the connection cable to the sensor.
Diagnosis 5 Diagnosis 5.1 Recurring test acc. to WHG The implementation of the recurring test acc. to WHG is regulated in the general type approval no. Z-65.11-154, Z-65.11-285 (see item 8 of the certificate). Please give attention to these higher-priority approvals when VEGASWING 81A and 83A are used as part of an overfill protection system acc. to WHG.
Diagnosis a. Current value < 2 mA - Check the voltage supply on the connection cable to the sensor. The voltage should be approx. 17 … 20 V. If you measure a value below 17 V, it indicates a defect in the signal conditioning instrument. In this case, send the instrument for repair to VEGA. - If the red fault signal lamp continues to light, separate the connection cable from the signal conditioning instrument and connect a resistance of 1 kΩ to the sensor inputs of the signal conditioning instrument.
