This signal provides the status of input voltage of
ARPS
.
Normal status: Input voltage of
ARPS
is correct (>190 VAC).
Status = OFF: There is a power supply failure detected by
ARPS
.
Failure means that input voltage is
<190 VAC
for more than
20 ms
.
In that case,
24V1
output is maintained for
~100 ms
,
13V
output is maintained for ~
300 ms
, there is no
voltage backup on
24V2
and
24V3
outputs.
