4. Easy commissioning
1.
With the equipment isolated from the supply check tightness of all connections, earth bonding, fuses, free
movement of contactors.
2.
Check that the requirements for the cable cross section and the fuses are respected with regard to the
total bank power.
3.
Check that the C.T. is properly located on line L1 i.e. the only line where the PF Controller voltage is not
taken (The PF Controller should be connected between L2 and L3).
4.
Remove the C.T. short circuit by opening or removing the bridge of the C.T. wire connector (inside the
bank).
Note: The APC is normally equipped with an RVC controller. To carry on with this commissioning,
follow the points below. If your APC is equipped with an optional RVT, refer to RVT instruction
manual and don’t follow the points below.
5.
Switch the voltage on.
After a power outage, the reset delay time is 40 seconds. During this delay time, the disconnection
indication blinks and the alarm contact remains closed.
Check that all the fans are in good working order.
If it’s not working properly, refer to the Chapter 5. Troubleshooting.
6.

“ ” starts flashing. Phase, C/k and Delay parameters are automatically set. Note that the delay value
remains unchanged if it is set above or equal to 40 sec. before commissioning.
If an error is detected, the AUTO SET procedure is stopped and an error message is displayed.
In this case, refer to the RVC Installation and operating instructions, § Error messages for a complete
