1495 CB1 CS2 AngHigh+
Line/Bus1 phase angle in range: +Angle 1-2 to
+180deg (anticlockwise from Vbus)
P544 and P546 only
1496 CB1 CS2 AngHigh-
Line/Bus1 phase angle in range: -Angle 1-2 to
-180deg (clockwise from Vbus)
P544 and P546 only
1497 Lead AR 1P PSL
If setting "Lead AR Mode" = Opto, then if input
DDB "LARSP" is high, the leader CB is
enabled for single phase autoreclose, if
"LARSP" is low, the leader CB is NOT enabled
for single phase autoreclose.
P544 and P546 only
1498 Lead AR 3P PSL
If setting "Lead AR Mode" = Opto, then if input
DDB "LAR3P" is high, the leader CB is
enabled for three phase autoreclose, if
"LAR3P" is low, the leader CB is NOT enabled
for three phase autoreclose.
P544 and P546 only
