ARMY TM 9-6115-60412 NAVY NAVFAC P-8-633-12 (c) Lower frequency of incoming set using Its FREQ ADJ rheostat R102R SYNCHROSCOPE M106R pointer should slowly rotate In the clockwise (fast) direction but still pass through the 12 o'clock position when the SYNCHRONIZING LIGHTS DS110R and DS111R are dark. (d) Monitor Incoming generator and bus voltages using GEN/BUS VOLTMETER selector switch S112R and AC KILOVOLTS meter M101R on the Incoming sets RCM. Adjust VOLT ADJ rheostat R101R on the RCM and continue adjusting until GEN and BUS voltages are equal. With GEN and BUS voltages equal, SYNCHROSCOPE M106R pointer should stop at 12 o'clock position and SYNCHRONIZING LIGHTS DS110R and DS111R should go dark. (e) With GEN and BUS voltage equal, close incoming set load circuit breaker CB101 using BREAKER CONTROL switch S4R on its RCM. When breaker is closed, and sets are in parallels, SYNCHROSCOPE pointer should remain at the 12 o'clock position (in sync). (f) Replace SYNCHROSCOPE M106R if it falls operational test as described above. (2) Replace. (a) Shut down generator set or set LOCAL REMOTE SW S2 In the generator set control room to LOCAL to deenergize the RCM. (b) Open the RCM panel by unlocking three oval studs across the top of the panel. (c) Tag and disconnect wires from SYNCHROSCOPE meter M106R (6) Figure 5-2) terminals. (d) See Figure 5-2 Remove nuts and lockwashers from SYNCHROSCOPE meter M106R (6) mounting studs and remove meter. (e) Remove nuts and lockwashers from mounting studs of replacement SYNCHROSCOPE M106R (6), if installed. (f) Install replacement SYNCHROSCOPE meter M106R (6) and secure with nuts and lockwashers. (g) Connect wires to M103R terminals as tagged. Remove and discard tags. (h) Close RCM panel and secure by locking three oval studs across the top of the panel. g. BREAKER CONTROL Switch S4R (7. Figure 5-2). The BREAKER CONTROL switch S4R (7) is a three-section (or deck) rotary, dual contact design. The BREAKER CONTROL switch S4R is used to open or close load circuit breaker CB101. (1) Test. (a) Shut down the generator set. See Figure 2-23. (b) Open the RCM panel by unlocking three oval studs across the top of the panel. (c) Tag and disconnect wires from BREAKER CONTROL switch S4R terminals. NOTE Switch wiring position numbers are translated as follows: the first digit defines the section, or deck, In relation to the handle end; the second digit is a specific terminal on that deck. For example. position 23 is located on the second deck, the contact is terminal number three. (d) Set a multimeter test to RX1 scale and test for contact continuity in the switch positions specified. Meter should Indicate 0 ohms at the points marked In Figure 4-67. (e) Multimeter should indicate infinite ohms at all open contacts in Figure 4-67. NOTE An integral spring return mechanism returns the handle to the normal-vertical position except in the pull-to-lock position. Slip contacts are incorporated to maintain contact closure in the last commanded position. These slip contacts are also used for the OPEN indicator light DS33 and the CLOSED indicator light DS34. 5-17
