The following procedures for checking the accessories are to be performed before they are
put into service:

to
be checked
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 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.
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.
