Relay output "K1" for fault reporting (factory function), max. contact load AC 250 V 2 A
- During operation the relay is energised, i.e. the connections "11" and "14" are bridged
- In case of a fault, the relay is de-energised, i.e. the connections "11" and "12" are bridged
- In case of a shutdown using the enable (D1 = Digital In 1) the relay remains energised
