Description
Correct network parameters,
the relay is on
Countdown to switch-on or
switch-off of the relay
(depending on the current
state of the output)
Asymmetry or exceeding of the
voltage threshold. Relay switched
off (voltage value of any of the
phases below 150 V or above
280 V or asymmetry above the
set value)
Incorrect phase sequence.
(The system detected an incorrect
phase rotation sequence
on the input terminals)
