4.16 Configurable LED
The relay has total five LED’s for user defined signaling. The can be configured
with the same signals as the binary output contacts. They can be individually
configured for following different operating modes:
1. Self-reset mode (S): In self-reset mode, the LED follows the behavior of the
triggering signal. The LED remains in active state till trigger persists.
2. Hold mode (H): Once LED is activated, it will remain active even if trigger
signal drops.
LED can be reset by all possible reset input triggers
a local HMI by reset key combination
b Reset binary input
c Reset command from optional communication module via MODBUS
/ IEC.
All five user defined LED’s can be triggered by different protection and control
signals. It is possible to map same signal to trigger more than one binary output.
The signals available for triggering binary outputs are as follows:
 Individual start of protection functions I>, I>>, I>>>, Io> and Io>>
 Individual trip of protection functions I>, I>>, I>>>, Io> and Io>>
 External user defined Signal 1 to Signal 3 available at binary input (configured
via binary input menu)

LED
Default configuration
Ready (Green)
LED indicates that relay has no internal fault and is powered up for desired
functionality. It glows after internal health check after power on and continue
to glow until power goes off or there is internal fault in the relay
Start (Yellow)
Start LED for any protection function start
Trip (RED)
Common trip LED for overcurrent and earth fault trip indication
LED 1 (RED)
User configured:
Default: Trip Ip => Trip overcurrent faults (I>, I>> and I>>>)
LED 2 (RED)
User configured:
Default: Trip Io => Trip earth faults (Io> and Io>>)
LED 3 (RED)
User configured:
Default: TCS Fault => trip circuit has failure
LED 4 (RED)
User configured:
Default: Spare (not configured)
LED 5 (RED)
User configured:
Default: Spare (not configured)
