1.3. 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 USB communications port
(KITCOM).
Once the KITCom is connected, the relay will be switched on and a led on the left of the relay
(led on) will blink indicating the relay is powered on through an external battery (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.
NOTE
: Date and time must be correctly set the first time the relay is operative.
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 transformation center is powered
up. So, the KITCOM is useful for cases like
commissioning operations, discharges and
repairs to the transformation center.
Using battery power does not block the
USB communications port, as it can be
used simultaneously.
Once the relay is powered through the Kitcom, it should be checked:
•
Model

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
