Procedure
Depending on how long the "TEST/RESET/RESET MODE" button is pushed, a specific test
is started:
Actuation time for
starting the test
Explanation
< 2 s
LED-Test
All four LEDs are activated.
1)
2 s ... 5 s
Current measuring test
Current measuring is tested in all 3 phases.
> > 5 s
Motor protection test disconnection
The entire control chain is tested, including the switching elements and the fault signaling output.
If the device responds as standard, an overload trip takes place. This can be reset immediately
without a cooling time by pressing the "TEST/RESET/RESET MODE" pushbutton again.
1)
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.
