1.3 Netvar Relay Module Front Panel View
Netvar Modular SVC Relay can be used without a screen due to its modular structure.
Therefore, it has many LEDs that can provide information to the user.
1) ENERGY LED: This is the LED that lights up when the device is energized. If it does not
light up, there is a problem in the supply part of the device.
2) ALARM LED: It is the LED that informs the user about the situation or problems that
occur in the system.
3) COMMUNICATION (COM) LED: It is the LED that gives communication information.
It indicates communication with the screen.
4) RUN LED: It is the LED that indicates the operation of the device. It lights up when the
device is running.
5) INDUCTIVE LED: If the total flowing reactive energy is above the specified inductive
limit, this blue LED lights up.
6) NORMAL LED: The green colored normal LED lights up if the total reactive energy
flowing from all phases is less than the End/Cap limits set in the relay.
7) CAPACITIVE LED: This red LED lights up if the total flowing reactive energy is above
the capacitive limit.
8) VOLTAGE LEDS: These are the voltage LEDs of three phases. The green color of these
LEDs informs the user that there is voltage in all 3 phases. Flashing or not lighting
indicates that there is a problem with the voltages.
