Testing the current and energy sensors
To test the current sensors and energy transducers, press the "START" button.
A lit-up LED confirms the proper operation of the corresponding sensor/converter. If an LED flashes, the corresponding
sensor/converter is not present, not properly connected is defective.
Testing the tripping function
To test the tripping function, press one of the buttons "L", "S", "I", "N" or "G".
Long-time delayed tripping Test
The long-time delayed short-circuit tripping function and the trip unit circuitry can be tested using the test device.
1
Charge the circuit breaker
2
Close the circuit breaker
3
Press the [L] button
The circuit breaker will trip after the set long-time delay time, plus approx. 2 seconds processing time, has elapsed. If the test device has
completed a test without faults, the "ETU STATUS" LED will light up continuously green. If a fault is detected, the LED will flash. The type of
flashing indicates what type of fault is present (fault codes are listed on page 9-104).
Short-time delayed tripping Test
The short-time delayed short-circuit tripping function and the trip unit circuitry can be tested using the test device.
1
Charge the circuit breaker
2
Close the circuit breaker
3
Press the [S] button
The circuit breaker will trip after the set short-time delay time, plus approx. 2 seconds processing time, has elapsed. If the test device has
completed a test without faults, the "ETU STATUS" LED will light up continuously green. If a fault is detected, the LED will flash. The type of
flashing indicates what type of fault is present (fault codes are listed on page 9-104).
Instantaneous tripping test
The instantaneous tripping function and the trip unit circuitry can be tested using the test device.
1
Charge the circuit breaker
2
Close the circuit breaker
3
Press the [I] button
The circuit breaker will trip after approx. 2 seconds processing time. If the test device has completed a test without faults, the "ETU STATUS"
LED will light up continuously green. If a fault is detected, the LED will flash. The type of flashing indicates what type of fault is present (fault
codes are listed on page 9-104).
