TROUBLESHOOTING
Safety Circuit Faults
Error Descripon Cause
F�364
Safety edge tesng failed. ‒ Safety edge was not acvated as expected when
requesng a test.
‒ The me between request for tesng and actual
tesng not synchronized.
F.365
Redundancy error with
interrupon.
‒ One of the processing channels for interrupon
detecon does not react idencally with the
second channel.
‒ Controller board defecve.
‒ Dynamic opcal system safety edge connected
but not set in Parameter P�460.
F�366
Too high a pulse frequency
for opcal safety edge.
‒ Defecve opcal safety edge.
‒ Defecve input for internal safety edge.
F�369
Internal safety edge
incorrectly parameterized.
An internal safety edge is connected but deacvated.
F�371
Number of edge trips for
external safety edge has
reached set limit.
Parameterized, maximum number of safety edge trips
during a gate cycle was exceeded.
F�372
Redundancy error with
short circuit.
‒ One of the processing channels for short circuit
detecon does not react idencally with the
second channel.
‒ Controller board defecve.
F�373
Fault in the safety edge
(message comes from
module).
‒ Cable break to safety edge, no edge connected,
edge terminaon resistor incorrect or defecve.
‒ Jumper for terminaon resistor in wrong posion.
‒ Safety edge processing selected with Parameter
P�470, but module not plugged in or wrong
module.
F�374
Safety bar tesng failed. ‒ Pre-limit switch for safety edge incorrectly set or
defecve.
‒ Processing module defecve.
‒ Safety edge defecve.
F�379
Safety edge detecon
defecve (coding pin or
parameter seng).
‒ No module plugged in but was reported as present
by a parameter.
‒ The controller was started up with a dierent
module than the one currently plugged in.
