Powering the relay up
Thanks to the external battery KITCOM the powering and adjusting process of the relay is very
easy and it allows the user to test the relay.
The power comes from two AA batteries (IEC LR06) of 1.5 Volts placed at the bottom of the
kitcom. The equipment has a small Dc/Dc power supply that raises the voltage till the required 5
volts to operate the equipment and that is plugged into the front RS232 communications port
(KITCOM).
The relay is totally maintenance free. This is, there is no need of batteries to log events and
fault reports and there is no need of batteries to maintain date and time.
Besides, the possibility of using external battery power, together with the possibility of activating
the trip contact from the test menu, allows the trip circuit to be tested before the distribution
center is powered up.
The SIL-A is designed to be powered with an auxiliary voltage of 24-230Vac/dc.
The tolerance for the voltage is -20%/+10%. Outside of this range is possible for the relay to
work but is not guaranteed.
Once the relay is powered through the Kitcom, it should be checked:
•

Directly, complete model
on top line and phases/neutral
current measurement on bottom
line are displayed.
Once “C” key is
pressed the name of phase and
neutral
currents
(instead
the
complete model) is displayed on
the top of LCD Standby screen.
