Function
Clocking for contactor coil
Voltage monitoring
Signal delay
Thermistor evaluation
Reversal interlock
Control state monitoring
Fault detection
The errors at the right cause the output drivers
to switch off and lead to an fault message
(0 signal on X1 pin 14)
Storing of fault message
RESET
Faults in the thermistor circuit require a RESET
Notes Note the following:
• On the board there are voltage-sensitive components. This requires ESD measures while installing the
• The connection of a thermistor circuit is mandatory.
• Only thermistor circuits with reliable isolation from the main circuit may be used.
• For the auxiliary voltage supply (AUX PWR) a PELV power supply unit must be used.

– Switch-on pulse 200 ms
– Followed by clocking with 500 Hz and approx. 40 % ON period
– Function enabled for U
– Function disabled for U
– 200 ms signal delay before fault message
– 40 ms signal delay before RESET accepted
– 200 ms dead interval for reversing function
– Open circuit detection (R >3710)
– Short-circuit detection (R <10 )
– Overtemperature tripping (contactor release: R >3710 )
– Reset accepted (R <1535 )
– Electrical via NC contact on opposing contactor and electronic interlock
– Feedback for contactor position via positively driven NC contact
– Contactor does not pick up (NC contact does not open)
– Contactor does not drop out (NC contact remains open)
– Clockwise and counter-clockwise rotation triggered simultaneously
– Auxiliary voltage missing or voltage too low
– Thermistor open circuit
– Thermistor short circuit
– Thermistor triggering
– The fault message remains until the cause of the fault has been eliminated.
– Faults in the thermistor circuit additionally require a RESET.
– Electrical RESET (signal change 0-1-0 on X1 pin 4; the1 signal must be at least 40 ms
long)
– Power-On-RESET (interrupt U
board.
