ARMY TM 9-6115-464-34 AIR FORCE 35C2-3-445-2 NAVY NAVFAC P-8-624-34 Section Vlll. MAINTENANCE OF GENERATOR SET CONTROLS 3-58. GENERAL. This section contains maintenance instructions for the generator set controls. The control cubicle assembly and sensing monitors contain the controls, instruments and indicators for controlling and monitoring the operation of the generator set. Precise models of the generator set incorporate a governor control unit which signals the actuator unit to change the fuel injection pump governor setting which controls engine speed and, thus, generator frequency. This function is assumed by the manual speed control on utility models. The interconnecting wiring harnesses provide electrical connection between major assemblies and the control cubicle and fault locating indicator. 3-59. CONTROL CUBICLE ASSEMBLY. a. Frequency Meter and Transducer. (1) (2) (3) (4) (5) (6) (7) (8) Refer to the Operator and Unit Maintenance Manual and remove, clean, and inspect frequency meter and transducer. Install frequency meter and transducer in a test setup as shown in figure 3-54. NOTE Test frequency meter must have an accuracy of 0.05 percent. Activate sinusoidal source and adjust its output as indicated by the test frequency meter to the lowest frequency indication on the frequency meter being tested (388 Hz for a 400 Hz frequency meter and 48 Hz for a 50/60 Hz frequency meter). Rotate adjusting screw of frequency meter being tested until its indication exactly matches that of the test frequency meter. If the frequency meter being tested cannot be properly adjusted, replace it and the frequency transducer. When frequency meter being tested has been properly adjusted, slowly increase the sinusoidal source frequency to the highest value of the frequency meter being tested (412 Hz for a 400 Hz frequency meter and 62 Hz for a 50/60 Hz frequency meter). If at any point the indication of the frequency meter being tested varies more than 0.25 percent from that of the test frequency meter, replace both transducer and frequency meter being tested. Refer to the Operator and Unit Maintenance Manual and install frequency meter and transducer. b. Kilowatt Meter and Thermal Converter. (1) Refer to the Operator and Unit Maintenance Manual and remove, clean, and inspect kilowatt meter and thermal converter. (2) Test ac kilowatt meter and converter as follows: (a) Connect a calibrated kilowatt meter and a suitable variable load to the generator set load terminal board. (b) Refer to the Operator and Unit Maintenance Manual and start the generator set. 3-130
