Procedure
1. Power the protection release with the Vaux auxiliary power
supply.
2. Power the Ekip Com Actuator contacts.
3. Load the springs.
4. Select "close CB" from the Ekip Touch menu
Result: The circuit-breaker closes correctly; the signals are
normal.
NOTE! The test can be performed if the protection
release and the coils are energized.
1. Open the circuit-breaker
2. Keep the opening push-button pressed
3. Turn the key and remove it
4. Attempt the circuit-breaker closing operation.
Result: Both manual and electrical closing are prevented.
1. Connect the auxiliary contacts to appropriate signalling
circuits or to the multimeter.
2. perform some closing and opening operations on the
circuit-breaker.
Result: signalling occurs normally.
1. Connect the auxiliary contacts to appropriate signalling
circuits.
2. next bring the circuit-breaker to the connected, isolated for
test and disconnected position.
Result: the signals due to the relative operations are normal.
1. Perform operating tests.
Result: the locks function correctly.
1. Perform operating tests.
Result: the locks function correctly.
1. Perform a few racking-in and racking-out operations.
Result: in the rack-in operation the circuit-breaker is
connected correctly. There is no particular resistance during
the first turns of the handle.
Verify the installation The value of the power supply auxiliary
voltage of the auxiliary accessories must be between 85% and
110% of the rated voltage for the auxiliary accessories.
1. Power the protection release
Result: Verify that Power LED is lit up on each accessory
present.
Make sure that the Local Bus communication line is activated
on the protection release.
1. In the case of Neutral external sensors, single-pole or
differential, to set the model and protection parameters
appropriately.
Result: No alarm present on the protection release.
WARNING! During this phase the circuit-breaker
must be open and withdrawn (if withdrawable).
