Section I. DESCRIPTION AND USE OF OPERATORS
CONTROLS AND INDICATORS
2-1. OPERATORS CONTROLS AND INDICATORS.
Prior to placing the generator set into operation, personnel must be familiar with the location and function
of all switches, controls, and indicators. Controls and indicators required for generator set operation are
described below and identified in Figure 2-1. Refer to the generator set electrical schematic, Figure FO-1, for
HOURS Meter (M3)
Indicates hours of generator set operation.
FUEL LEVEL Meter (M5)
Indicates amount of fuel remaining in the
generator set fuel tank.
VOLTAGE Meter (M1)
Indicates generator set output voltage.
LOAD Meter (M2)
Indicates generator load in kilowatts.
DC CIRCUIT BREAKER (CB1)
Trips to stop generator set operation in case of
electrical surge in DC control system. Push to
Fault Indication Module (A2)
Contains lights that indicate generator set
operating conditions. Includes the following
ENGINE HIGH TEMP fault (red)
LOW OIL PRESSURE fault (red)
NO FUEL fault (red)
OVERVOLTAGE fault (red)
OVERLOAD SHORT CIRCUIT fault (red)
BATTLE SHORT ON operation (yellow)
Dual purpose FAULT RESET / PUSH TEST
switch allows operator to test indicator lights
before operation, and reset fault isolation
module after fault has been remedied.
BATTLE SHORT Switch (S7)
Two-position switch that allows generator set
operation under certain fault conditions.
ON position bypasses all faults except short
circuit conditions. BATTLE SHORT
indicator on fault indicator module A2
(see item 6) will light when switch is in
OFF position returns generator set to normal
operating mode, allowing faults to halt
generator set operation.
Convenience Receptacle (J1) (60Hz only)
Single phase duplex receptacle which allows
120VAC appliance or tool connection.
GROUND FAULT CIRCUIT
INTERRUPTER (GFCI) (CB3) (60Hz only)
Provides automatic circuit interruption and
circuit protection for the convenience
SLAVE RECEPTACLE (SR1)
Allows for 24VDC auxiliary power connec-
tion for starting generator set. NATO style.
Generator set ground terminal.
L1, L2, N Terminals
Generator set alternating current (L1, L2) and
neutral (N) terminals.
