WRN-99
No release for main contactor
Cause:
The main contactor may not switch on: either the release of the safety circuit is missing, or a shutdown is holding it off.
Measure:
Check the safety circuit and the emergency stop, see
Section 7.3, “Main contactor ON/OFF”
. If a load shedding preceded it,
MSG-60, “Main conductor tripped ‹triggering notification›”
names the reason.
