DDB no. English text Source Description
1410 Follower AR 3P Auto-reclose
If setting "Foll AR Mode" = Opto, then if input
DDB "FAR3P" is high, the follower CB is
enabled for three phase autoreclose, if
"FAR3P" is low, the follower CB is NOT
enabled for three phase autoreclose.
P544 and P546 only
1411 CB2 AR 3p InProg Auto-reclose
Autoreclose in progress CB2
P544 and P546 only
1412 En CB2 Independ Auto-reclose
DDB mapped in PSL from opto or comms
input. A signal from an autoreclose scheme
on an adjacent circuit having shared control of
CB2, to allow the "Independent Follower time"
to start. (see description for DDB "CB2 Indep
Init A" or "CB2 Indep Init B" or "CB2 Indep Init
C" ).

Not used
1417 Ext Rst CB2 AROK PSL
DDB mapped in PSL from opto or comms
input. This input DDB is used when required
to reset any CB2 Successful Autoreclose"
signal.
P544 and P546 only
1418 Ext Rst CB2Shots PSL
DDB mapped in PSL from opto or comms
input. This input DDB is used when required
to reset the CB2 cumulative "Shots" counters.

1419 Rst CB2 CloseDly PSL
DDB mapped in PSL. Reset Manual CB2
Close Timer Delay (stop & reset Manual Close
Delay time for closing CB2).
P544 and P546 only
1420 Inhibit AR PSL
DDB mapped in PSL from opto or comms
input. External signal to inhibit autoreclose.
P544 and P546 only
1421 Block CB2 AR PSL
DDB mapped in PSL from opto or comms
input. External signal to force CB2
autoreclose to lockout.

1422 Rst CB2 Lockout PSL
DDB mapped in PSL from opto or comms
input. Reset Lockout Opto Input to reset CB2
Lockout state
P544 and P546 only
1423 MCB/VTS CS2 PSL
DDB mapped in PSL from opto input (Bus2 VT
secondary MCB tripped or VT fail detected by
external VTS scheme), or signal from host
relay VTS scheme
