ARMY TM 9-6115-60412 NAVY NAVFAC P-8-633-12 o. SYNCHROSCOPE Switch S115R (20, Figure 5-2). The SYNCHROSCOPE switch S115R Is a two-position switch consisting of three decks. This switch "arms" SYNCHRONIZING LIGHTS DS110R and DS111R. Inspect for cleanliness and damage Check security of mounting to panel, wiring connections, and switch knob. Check for proper operation of click stops in both positions. p. PARALLEL Indicator DS35R and SINGLE SET Indicator DS36R (21, Figure 5-2). These indicators light to provide a visual display of the PARALLEL SWITCH position. Inspect that lenses are secure and not cracked and lamp holders are secure in panel Check wiring security at rear of panel. q. MASTER Switch S9R (24, Figure 5-2). MASTER (Start-Stop-Run) switch S9R is a two-pole, spring return, toggle switch which allows the operator to start up, or stop, the generator set from the remote control module. Inspect for cleanliness and signs of damage. Check security of mounting and for satisfactory operation in START, RUN, and STOP positions. r. HIGH COOLANT/LOW OIL PRESSURE/FAULT Lights (25. Figure 5-2). These lights illuminate to indicate that a fault condition has occurred at the generator set. Inspect that lenses are secure and not cracked and that lampholders are secure in panel. Check wiring security at rear of panel. s. TEL JACK J15R (28, Figure 5-2). The TEL JACK allows communications between the remote control module site and the main generator set through the head set. (1) Inspect. Check TEL JACK for security of mounting, cleanliness, and signs of damage. Check wiring security at rear of panel. (2) Replace. (a) Tag and disconnect wiring to TEL JACK (28, Figure 5-2). (b) Remove TEL JACK (28) from rear of panel by removing mounting nut holding jack cover (29) to the front panel. (c) Position TEL JACK (28) from rear of panel and attach jack cover (29) from front and install nut removed in step (b), above. (d) Connect wires and discard tags. t. ANNUNCIATOR TEST. ALARM SILENCE. AND EMERGENCY SHUTDOWN PUSHBUTTON SWITCHES, S15R. S16R, and S7R (30, 31, and 32. Figure 5-2). These switches test the annunciator alarm, silence the horn when the alarm sounds and shut down the generator set. Inspect pushbutton switches for cleanliness and damage. Check security of panel mounting panel and switch wiring connections. NOTE To reset fault alarm, annunciator reset pushbutton S16A In generator set must be actuated. u. Connector Receptacle J26R (36. Figure 5-1). The connector receptacle J26R permits easy connection between the generator set control room and the remote control module by providing a single connector for all the wires contained in the remote control cable. Inspect for cleanliness, security of mounting, wiring security, and damage. Ensure that cap fits over receptacle and that threads are not damaged. v. Wiring Harness (Figure 5-3). Interconnects all RCM contacts and indicators to generator set. Inspect the wiring harness for loose mounting or connections, fraying, damaged insulation, sleeving, or lugs. w. Diode Assembly (DIR-D6R) TB1R. The diode assembly prevents spurious current surges through lamps. Inspect blocking diodes DR1 through DR6 mounted on terminal block TB1R (11, Figure 5-1) inside the RCM chassis. Check diodes for loose connections, signs of overheating, and signs of damage. x. Annunciator Horn LS1 R. The horn provides an audible alarm when fault condition occurs. Inspect annunciator horn LS1R (12, Figure 5-1) inside the chassis for secure mounting, electrical connections, and signs of damage. y. Frequency Transducer A103R (28. Figure 5-1). The frequency transducer provides driving current signals for the frequency meter M103R. Frequency transducer A103R is mounted at the interior lower right chassis of the remote control module. Inspect the transducer for secure mounting, wiring connections, and signs of damage. 5-11
