14.1 Motor protection functions (overload protection, thermistor protection)
Test phases
● Phase 1: Hardware test / lamp test (0 to 2 s):
The hardware (e.g. the thermistor electronics) is tested, all LEDs and displays are
activated, including the lamp control. Contactor controls remain unchanged.
● Phase 2: Hardware test results (2 s to 5 s):
If there is a fault, the "HW fault basic unit" fault is triggered.
If there is no fault:
– the "GEN. FAULT" LED flashes if no main current is flowing
– the "GEN. FAULT" LED flickers; if main current is flowing in all three phases
● Phase 3: Relay test (> 5 s):
If testing is carried out with tripping, the contactor controls are deactivated.
The contactor control can only be shut down by means of the "Test 1" function block and in
the "Local 1-3" operating mode, using the "TEST / RESET" button on the basic
device / operator panel.
The following table shows the test phases performed when the "TEST / RESET" button is
pressed for the required length of time:
