Central fault message

Floating contact:
■ Closed: Fault
■ Open: No fault
■ Not suitable for safety LV.
Connection values (contact loads):
■ Voltage: 230 V~
■ Max. switching current: 4(2) A

On-site connection, see separate "connec-
tion and wiring diagram" sheet 21.

Note
■ No parameters need to be set.
■ The contact issues a short pulse when

the power supply is switched on. Ob-
serve the pulse when processing the
message via communication tools.
