Check for secure attachment topanel and for chipped, cracked, or loose cover glass.f.SYNCHROSCOPEMeterM106R(6.Figure5-2).SYNCHROSCOPE M106R indicates the phase relationshipbetween 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.BREAKERCONTROLSwitchS4R(7.Figure5-2).BREAKER CONTROL switch S4R is used to open or close loadcircuit breaker CB101. Inspect for cleanliness and signs of damage. Check security of panel mounting and wiringconnections. Check handle operation in CLOSE position and in the TRIP position. Spring-loaded handle shouldreturn to vertical position after each command operation with handle index on the target window. Target windowshould 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 pushedfor release and then should spring back to normal vertical position.h.AMMETERSwitchS114R(8.Figure5-2).AMMETER switch S114R is a six-section rotary tap-switch contactdesign. An integral detent assembly provides positive click stops at operational switch positions. The switch is usedin conjunction with AC AMPERES meter M102R to select any of three phases for a current draw indication. Inspectfor cleanliness and damage. Check security of mounting to panel, wiring connections, and switch knob. Check forsatisfactory operation of click stops in all five positions.i.GEN/BUSVOLTMETERSwitchS112R(9,Figure5-2).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 knobCheck security of knob on shaft. Rotate full range in both directions while observing that travel is smooth anduninterrupted and no evidence of bent shaft is noted. Check rear of panel for security of mounting and wiringconnections.j.VOLTADJRheostatR101R(11,Figure5-2).VOLT ADJ rheostat R101R is used to manually adjust voltage outputof generator G1. Inspect for cleanliness and damage to knob. Check security of knob on shaft. Rotate full range inboth 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.PARALLELSWITCHS6R(12,Figure5-2).PARALLEL SWITCH S6R is a two-section, or deck, rotary switch withhandle spring return to vertical position following a command operation. The switch is used to select either single orparallel generator set operation. Inspect for cleanliness and damage. Check security of mounting to panel, wiringconnections, and switch knob. heck for proper operation in both PARALLEL and SINGLE positions. Spring actionshould return knob to normal (vertical) position.I.FREQADJRheostatR102R(13,Figure5-2).FREQ ADJ rheostat R102R is used to manually adjust the frequencyof 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 bentshaft is noted. Check rear of panel for security of mounting and wiring connections.m.OPENIndicatorDS33RandCLOSEDIndicatorDS34R(14,Figure5-2).These indicators light to provide a visualdisplay of the BREAKER CONTROL switch position. Inspect that lenses are secure and not cracked andlampholders are secure in panel. Check wiring security at rear of panel.n.SYNCHRONIZ1INGLIGHTSDS11ORandDS111RandResistorsR11ORandR111R(18and49.Figure5-2).These lights indicate the phase relationship of the bus and generator set to be paralleled Inspect that lenses aresecure and not cracked and lamp holders are secure in panel. Check wiring security at rear of panel. Checkdropping resistors R110R and R111R mounted at back of panel on either side of the synchronizing lights for securemounting and electrical connections.5-10
