7.7 Digital mains breaker control

The unit will normally execute the automatic mains failure sequence based on the settings adjusted in the
system setup. Besides these settings it is possible to configure a digital input that can be used to control the
mains return sequence. This input is the "Mains Okay" input. The purpose of this function is to let an external
device or an operator control the mains return sequence. The external device can e.g. be a PLC.
The flowchart below shows that if the input is configured, it needs to be activated (by a pulse) in order to ini-
tiate the mains return sequence. The load will continue on generator supply if the input is not activated.
