POWER FACTOR Meter M104R (4, Figure 5-2). POWER FACTOR meter M104R indicates the power factor of the
load on generator G1. Inspect for cleanliness, broken Indicators, and signs of damage. Check for secure
attachment to panel and for chipped, cracked, or loose cover glass.
e.
AC KILOWATTS Meter M107R (5. Figure 5-2). AC KILOWATTS meter M107R indicates the power output of the
generator set. Inspect for cleanliness, broken indicators, and signs of damage. Check for secure attachment to
panel and for chipped, cracked, or loose cover glass.
f.
SYNCHROSCOPE Meter M106R (6. Figure 5-2). SYNCHROSCOPE M106R indicates the phase relationship
between the bus and a generator to be paralleled. Inspect for cleanliness, broken indicators, and signs of damage.
Check for secure attachment to panel and for chipped, cracked, or loose cover glass.
g.
BREAKER CONTROL Switch S4R (7. Figure 5-2). BREAKER CONTROL switch S4R is used to open or close load
circuit breaker CB101. Inspect for cleanliness and signs of damage. Check security of panel mounting and wiring
connections. Check handle operation in CLOSE position and in the TRIP position. Spring-loaded handle should
return to vertical position after each command operation with handle index on the target window. Target window
should show red when last command operation was CLOSE and green when last command operation was TRIP.
Check for proper PULL TO LOCK operation for handle In TRIP position. Handle should remain locked until pushed
for release and then should spring back to normal vertical position.
h.
AMMETER Switch S114R (8. Figure 5-2). AMMETER switch S114R is a six-section rotary tap-switch contact
design. An integral detent assembly provides positive click stops at operational switch positions. The switch is used
in conjunction with AC AMPERES meter M102R to select any of three phases for a current draw indication. Inspect
for cleanliness and damage. Check security of mounting to panel, wiring connections, and switch knob. Check for
satisfactory operation of click stops in all five positions.
i.
GEN/BUS VOLTMETER Switch S112R (9, Figure 5-2). The GEN/BUS VOLTMETER switch S112R is a two-
section, rotary tap-switch contact design. An integral detent assembly provides click stops at all eight positions.
This switch is used in conjunction with AC KILOVOLTS meter M101 R to select any one of the three generator.
phases at either the generator or at the bus to check for voltage levels. Inspect for cleanliness and damage to knob
Check security of knob on shaft. Rotate full range in both directions while observing that travel is smooth and
uninterrupted and no evidence of bent shaft is noted. Check rear of panel for security of mounting and wiring
connections.
j.
VOLT ADJ Rheostat R101R (11, Figure 5-2). VOLT ADJ rheostat R101R is used to manually adjust voltage output
of generator G1. Inspect for cleanliness and damage to knob. Check security of knob on shaft. Rotate full range in
both directions while observing that travel is smooth and uninterrupted and no evidence of bent shaft is noted.
Check rear of panel for security of mounting and wiring connections.
k.
PARALLEL SWITCH S6R (12, Figure 5-2). PARALLEL SWITCH S6R is a two-section, or deck, rotary switch with
handle spring return to vertical position following a command operation. The switch is used to select either single or
parallel generator set operation. Inspect for cleanliness and damage. Check security of mounting to panel, wiring
connections, and switch knob. heck for proper operation in both PARALLEL and SINGLE positions. Spring action
should return knob to normal (vertical) position.
I.
FREQ ADJ Rheostat R102R (13, Figure 5-2). FREQ ADJ rheostat R102R is used to manually adjust the frequency
of the output of generator G1. Inspect for cleanliness and damage to knob. Check security of knob on shaft.
Rotate full range In both directions while observing that travel is smooth and uninterrupted and no evidence of bent
shaft is noted. Check rear of panel for security of mounting and wiring connections.
m.
OPEN Indicator DS33R and CLOSED Indicator DS34R (14, Figure 5-2). These indicators light to provide a visual
display of the BREAKER CONTROL switch position. Inspect that lenses are secure and not cracked and
lampholders are secure in panel. Check wiring security at rear of panel.
n.
SYNCHRONIZ1ING LIGHTS DS11OR and DS111 R and Resistors R11OR and R111R (18 and 49. Figure 5-2).
These lights indicate the phase relationship of the bus and generator set to be paralleled Inspect that lenses are
secure and not cracked and lamp holders are secure in panel. Check wiring security at rear of panel. Check
dropping resistors R110R and R111R mounted at back of panel on either side of the synchronizing lights for secure
mounting and electrical connections.
