Procedure
be checked
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.
Gearmotor 2. Perform some closing and opening operations.
Result: The gearmotor reloads the springs after every closing
operation.
1. Power the under-voltage coil at the relevant rated voltage and
perform the closing 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 closing operation on the circuit-breaker.
Under-voltage coil
Result: The circuit-breaker closes; the signal changes over.
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.
1. Close the circuit-breaker.
2. Power the opening coil at the relevant rated voltage.
Opening coil
Result: The circuit-breaker opens correctly; the signals are normal.
1. Open the circuit-breaker.
2. Load the springs manually or electrically.
Closing coil
3. Power the closing coil at its rated voltage.
Result: The circuit-breaker closes correctly; the signals are normal.
1. Power the protection release with the Vaux auxiliary power supply.
2. Power the Ekip Com Actuator contacts.
3. Close the circuit-breaker
Opening coil
4. Select "open CB" from the Ekip Touch menu
with Ekip Com
Result: The circuit-breaker opens correctly; the signals are normal.
Actuator
are energized.
