4-3. OPERATION
NOTE
Perform only those steps that are applicable to your BE3-25A as
indicated by parenthesis.
NOTE
If the governor and the voltage regulator are not properly adjusted
(refer to the individual governor and voltage regulator manuals),
the BE3-25A may not be able to drive the governor or voltage
regulator enough to allow synchronization.
a. Initial Set-Up.
(1)
(All Models.) Set the front panel TEST/OPERATE switch to the TEST position.
(2)
(All Summing Point Models.) If the internal reset feature is desired, connect the exter-
nal jumper (if not already installed) across terminals R1 and R2. If the reset function
is to controlled externally, remove the jumper and connect the external control con-
tacts (a switch or 52a contacts) across the terminals.
(3)
(All Models.) To enable the 0.75 second delay between synchronization and breaker
closure, connect an external jumper (if not already installed) across terminals D1 and
D2. To provide instantaneous time between synchronization and breaker closure,
remove any jumper connected across these terminals.
(4)
(Option D Only.) To enable the dead bus option, connect an external jumper (if not
already installed) across terminals DB1 and DB2. To disable this option, remove any
jumper connected across these terminals.
(5)
(Option 1 Only.) Refer to Figures 4-13 through 4-17 as appropriate, and either re-
move or install the Regulator Polarity Jumper at terminals VR3 and VR3 as directed
therein.
