Procedure
Gearmotor
1. Power the gearmotor for loading the springs at the relevant rated voltage.
Result: The springs are loaded correctly. The signals are normal. When the
springs are loaded the gearmotor stops.
2. Perform some closing and opening operations.
Result: The gearmotor reloads the springs after every closing operation.
NOTE!
If present, power the under-voltage coil in advance.
Under-voltage coil
1. Power the under-voltage coil at the relevant rated voltage and perform the clos-
ing operation on the circuit-breaker.
Result: The circuit-breaker closes correctly; the signallings are normal.
2. Turn off the voltage supply to the release. The circuit-breaker opens.
3. Power the under-voltage coil at the relevant rated voltage and perform the clos-
ing operation on the circuit-breaker.
Result: The circuit-breaker closes; the signal changes over.
WARNING! If the under-voltage coil has been tripped by a power
failure, the circuit-breaker can be closed only after the coil has been
energized electrically. Make sure that the coil has effectively been
tripped by a power failure. Otherwise, examine the circuit-breaker and
associated device to make sure that they are in a good condition.
Opening coil
1. Close the circuit-breaker.
2. Power the opening coil at the relevant rated voltage.
Result: The circuit-breaker opens correctly; the signals are normal.
Closing coil
1. Open the circuit-breaker.
2. Load the springs manually or electrically.
3. Power the closing coil at its rated voltage.
Result: The circuit-breaker closes correctly; the signals are normal.
Opening coil with Ekip
Com Actuator
1. Power the protection release with the Vaux auxiliary power supply.
2. Power the Ekip Com Actuator contacts.
3. Close the circuit-breaker
4. Select
“open CB”
from the Ekip Touch menu
Result: The circuit-breaker opens correctly; the signals are normal.
NOTE!
The test can be performed if the release and the coils are
energized.
