On earthed actuators, the actuator's 0 V connection must be connected to 0 V of the pe-

riphery supply (external supply voltage).

Reason: The switch (0 V periphery supply) in the PSSu E F BSW module is bridged when

the actuator's earthed 0 V connection is connected to 0 V on the connected periphery sup-

ply. In this case, the PSSu E F BSW registers a short circuit between 0 V of the external

supply voltage and 0 V of the connected periphery supply.

Error reaction: The PSSu will not start and all affected I/O-Groups (SafetyBUS p) remain in

a STOP condition.
