Trip Log - Danfoss MCD3000 Series Manual

Trip Log

When the MCD3000 enters a trip state, the cause of
the trip is recorded in a trip log. The trip log records
the cause of the last eight trip events. Each trip event
is numbered. The most recent event is numbered 1,
while the oldest is numbered 8.
ATTENTION
Control voltage must be present to enable the
MCD3000 to record the cause of a trip event.
Therefore, trips caused by, or involving a loss of
control supply voltage may not be recorded.
