Exception in the case of 3RM11/3RM13 Failsafe motor starters: in the case of 3RM11/3RM13 Failsafe motor starters,
the LED test is only carried out in the OFF state (without load current). In the ON state (with load current), the LEDs stay
unchanged.
Note
If the 3RM1 motor starter does not respond as in the table above during the function test,
check the connections and the supply to the 3RM1 motor starter. If the fault persists after
correct disconnection, the device must be replaced.
