start of the circuit only if both actuators signal release state (de-energised state) via
their auxiliary contacts (NC contacts).

Two-channel guard monitoring to ISO 14119 with at least one positively opening
position switch with cross-fault detection. The cross-fault detection function is only
guaranteed if the sensor’s channels switch against different potential as shown be-
low.
Actuator level
Two-channel power level (series circuitry of the actuator contacts). A relay or con-
tactor with positively driven contacts must be used.
Safety categorisation
