If SYNCHRONIZING LIGHTS are going on and off alternately, generator sets are
out of phase. Stop one generator set. Start, and if still out of phase, notify
higher level of maintenance.
Adjust frequency of first, operating, generator set to proper value.
Adjust frequency of second, incoming, generator set until SYNCHRONIZING LIGHTS go
on and off slowly at 2-3 second intervals.
Do not set circuit breaker of second, incoming, generator set to ON position
while SYNCHRONIZING LIGHTS are on. Failure to observe this caution could
result in damage to one or both generator sets.
Observe SYNCHRONIZING LIGHTS on incoming generator set. At the instant both lights
are out, set circuit breaker to ON position. The two power plant power units are now
operating in parallel.
Readjust VOLTAGE ADJUST rheostats on both power plant generator sets until both AC
AMMETERS indicate zero.
Readjust FREQUENCY ADJUST rheostats on both power plant generator sets until both
PERCENT POWER kilowatt meters indicate zero.
When load is applied to power plant in step (m), the difference in the kilowatt
load between generator sets must not exceed 10%. The difference between
current on any phase must not exceed 10%. If necessary, adjust R28 and/or
R29 respectively, to correct a kilowatt load or current imbalance.
Set both switches on switch box to ON position.
Before removing either power unit from parallel operation, make certain the
load applied to the power plant through the switch box does not exceed rating of
remaining power unit.
To remove either power unit from parallel operation, set generator set circuit breaker to
