Important:

Coil terminations should be suppressed with a surge protection device. Preferably a varistor (e.g. S10K30,

B72210S0300K101 or equivalent) should be installed in parallel, see “Cautions and warnings”. If an alternative

coil suppression device is used, the clamping voltage must not be smaller than 50 V.

Auxiliary contacts NC and COM are normally closed.

When the contacts are open and the coil voltage is “0 V”, the part is stuck.

Auxiliary contact

Example circuit to realize stuck detection:

The LED will be ON when the contactor is OFF.

In case the contactor is stuck, the Aux COM and Aux NC contacts will remain open, hence the circuit

is open, and the LED will be off, indicating the malfunction.
