ARMY TM 9-6115-60412 NAVY NAVFAC P-8-633-12 (d) Install replacement AMMETER switch S114 (8) by positioning the switch sections at the rear of panel and assemble the mounting plate from the front. Secure the entire assembly with three mounting screws. (e) Replace handle In the normal dial-vertical position and secure with its attaching screw. (f) Connect wires and remove and discard tags. (g) Close RCM panel and secure by locking three oval studs across the top of the panel. i. GEN/BUS VOLTMETER Switch S112R (9, Figure 5-2). GEN/BUS VOLTMETER switch S112R (9) is a two- section, rotary tap-switch contact design. An integral detent assembly provides positive click stops at all eight positions. This switch is used with AC KILOVOLTS meter to select any one of the three phases at either the generator or at the bus to check for voltage levels. (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. 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 terminal is number 3. (c) Tag and disconnect wiring to GEN/BUS VOLTMETER switch S112R contacts. (d) Set a multimeter to RX1 scale and, test for contact continuity in the switch positions specified in Figure 4-70. Meter should indicate 0 ohms at all points marked in the chart. (e) Multimeter should indicate infinite ohms at all blank places in the chart. (f) Replace GEN/BUS VOLTMETER switch S112R. If it falls testing as described above. (g) Connect wires to GEN/BUS VOLTMETER switch S112R as tagged. Remove and discard tags. (2) Replace. (a) Tag and disconnect wiring from GEN/BUS VOLTMETER switch (9) contacts. (b) Remove screw In center of switch S112R handle and slide handle off shaft. (c) Remove three screws from face of switch mounting plate on front of panel. Switch S112R sections may be removed from rear of panel as an assembly. (d) Install replacement GEN/BUS VOLTMETER switch S112R (9) by positioning switch section at rear of panel and assemble the mounting plate from the front. Secure the entire assembly with the three mounting screws. (e) Reinstall switch handle in the OFF position, ensuring that shaft is In the OFF condition. Secure handle with attaching screw. (f) Connect wires as tagged Remove and discard tags. (g) Close remote control panel and secure by locking the three oval studs at the top of the panel. j. VOLT ADJ Rheostat R101R (11, Figure 5-2). The VOLT ADJ rheostat R101R is used to manually adjust voltage output of generator G1. (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) Remove wire from terminal 3 of VOLT ADJ rheostat R101R (11). (d) Rotate knob fully counterclockwise. 5-19
