Forced
operation
Trip and control (annunciator) contacts can be forced to operate.
Operation
indication
Operation indicator LED comes on when the relay element operates.
LED indication: A-Phase, B-Phase, C-Phase, Zero-sequence, Instantaneous overcurrent element.
Display
RUN LED (green)
Indicate the result of automatic self-diagnosis. This LED is turned
on for normal and turned off for abnormal.
ALARM LED (red)
Indicate the result of automatic self-diagnosis. This LED is turned
off for normal and turned on for abnormal.
Self-diagnosis
(ALARM)
An electronic circuit and a built-in power supply are always supervised, and it outputs to the
RUN/ALARM LED and an ALARM contact.
