NOTE
If the REVERSE POWER indicator on the FAULT INDICATOR PANEL of
either generator set lights, and the AC circuit interrupter relay opens, open the
load contactor at load and resynchronize the generator sets (Repeat the
necessary steps d through j above).
Compare AC AMPERES meter (9) readings of both generator sets. If readings are not within 10
percent, notify next higher level of maintenance.
Compare PERCENT POWER meter (10) readings of both generator sets. If readings are not
within 10 percent, notify next higher level of maintenance.
Close control panel access cover (7) and secure with clamping
Perform the PMCS listed as DURING in table 2-2.

f.
If necessary to move a generator set which has been operating in parallel
with another generator set, shut down remaining generator set connected to
the load, prior to removing load and ground cables. Failure to observe this
warning can result in injury or death by electrocution.
CAUTION
Prior to removal of generator set from parallel operation, make sure load
does not exceed full load rating of generator set remaining on line. Failure
to observe this caution can result in damage to generator set.
At the control panel of the generator set that is to be taken off line, position AC CIRCUIT INTER-
RUPTER switch (13) in the OPEN position until indicator (14) goes out.
Set UNIT-PARALLEL switch (16) to UNIT.
On the switch box place the ON LINE switch (3 or 6) for the operating generator set in the OFF
position. (At switch box, ON and ON LINE lights for the generator shut down should be off).
Rotate MASTER switch to OFF position.
At the control panel of the operating generator set, place the UNIT-PARALLEL switch at UNIT.
Perform the PMCS listed as AFTER in Table 2-2 for the generator set that was shut down.
2-5.3.4 Load Transfer Procedures (Sets connected for parallel operation).
a.
One generator set (generator set 1) should already be on line and supplying power to the load,

For the generator set not running (generator set 2), perform the PMCS listed as BEFORE in
table 2-2.
