(a) (b) (c) (d) ARMY   TM   9-6115-464-34 AIR  FORCE  TO  35C2-3-445-2 NAVY  NAVFAC  P-8-624-34 With chassis cover (4, figure 3-130) removed, connect positive lead of voltmeter to heat sink where CR1-CR3 are mounted. Connect negative lead to heat sink where CR4-CR6 are mounted. (See item 17, figure 3–130). Apply 12 Vac (any frequency between 50 and 400 Hz) to pins A and B of connector J13. Voltmeter connected across heat sinks should indicate 9.3 Vdc. Remove 12 Vac from pins A and B and connect to E and F, then to J and K. In each case, voltmeter should indicate 9.3 Vdc. (4)   If the requirements of any test are not met, check components using figure 3-131 or 3-132 and table 3-8 as a guide to locate the malfunction. Correct before installing the static exciter and voltage regulator  assembly. g. Installation. (1) Position static exciter and voltage regulator to install Iockwasher (2, figure 3-130) and screws (1). (2)  Connect  electrical  connectors  to  static  exicter  and  voltage  regulator. 3-93. RELAY TABLE COMPONENTS ADJUSTMENTS. a. General. After maintenance has been performed on any of the relay table components, the appropriate adjustments shall be performed. b. Voltage Adjustment. (1)  Position voltage adjustment rheostat R2 on generator set control cubicle to the approximate midpoint. (2)  Refer to the Operator and Unit Maintenance Manual and start the generator set. (3)  Adjust voltage rheostat R2 to obtain generator assembly rated voltage at generator set load terminal board. c. Paralleling Adjustments. (1) (2) (3) (4) (5) (6) (7) Refer to the Operator and Unit Maintenance Manual and connect a rated load to the generator set load terminal board. Start the generator set and operate at full rated load. Install the shorting plug in the paralleling receptacle. Place the operations switch on the generator set control cubicle in the PARALLEL position. Adjust reactive current adjust potentiometer R29 of the special relay assembly to provide a special droop of 3 percent. Adjust the load sharing adjust rheostat (R28) of the precise relay assembly until 4 to 6 VDC appear across pins A and B of the paralleling receptacle. Insure that the positive lead of the meter is connected to pin A. Repeat same procedure for all other generator sets to be paralleled. Voltage readings must be identical on all generator sets to be paralleled to insure load sharing. Failure to make this adjustment will result in load rejection and/or safety system shutdown. NOTE Step (6) pertains to precise generator sets only. Refer to the Operator and Unit Maintenance Manual and shut down the generator set. 3-277
