Resetting the short circuit trip
Short-circuit hazard!
If you restart the compact starter after an overload trip and the cause of the short circuit has
not been eliminated, a new short-circuit trip will occur. A short circuit can cause burns and
plant damage.
Eliminate the cause of the short circuit before you restart the compact starter after a short-
circuit trip.
To reset a short circuit trip, turn the actuator to the
Function test
To test the short-circuit protection function, press the "TEST I>>" button ("Short-circuit
protection" test button). This can be done when the compact starter is de-energized.
After the "short-circuit protection" test button has been pressed, the breaker latching
mechanism trips and the actuator of the compact starter changes to the TRIPPED position.
The "Fault" signaling contact (terminals 77/78) opens.
The test can be terminated by turning the actuator first to the
READY position.
