Required only for optional Var/PF control. Var/PF is active with
52b open. Var/PF is inactive with 52b closed.
Parallel control and droop active with S2 open, inactive with S2
closed.
S1 (SPDT, spring-return to center-off position) adjusts DECS-100
setpoint.
Normally-open output contact closes for customer alarm or trip.
Analog input voltage between +/- 3 Vdc provides adjustment of
voltage setpoint.
Exter
nal fuses should be Bussman type KTK-10 or equivalent.
Sensing potential transformer is required if line voltage exceeds
660 Vac.
3-phase PMG is shown. For 1-phase PMG, omit B-phase
connection.
Optional voltage matching control input. Voltage matching is
active with S3 closed, inactive with S3 open.
Item not supplied by Basler Electric.
When generator rotation is ACB, the connections shown for CTB
s
hould be reversed.
