Description

Since the limit switch will be
monitored generally only
through the safety circuit
(normally no additional
separate contacts) the cause
of failure can also be at a
different contact within the
primary safety circuit.
Safety circuit inspection limit
switch open.
Error message from the drive
during a trip. At the same time,
the safety circuit was opened.
Since the drive usually also
detects an opened safety
circuit (drop off running
contactors), it is not sure if the
actual cause of the error is in
the drive or the safety circuit.
Safety light curtain is
interrupted during a trip.
According to EN81-20 it is
allowed to bypass safety circuit
of doors by a switch for service

This switch must be monitored
by one or more feedback
inputs.
The error occurs if not all
monitoring inputs have the
same state.
Safety gear triggered (safety
gear contact opened)
Safety circuit shaft doors still
