2-4 Operation TP-5631 7/96
Switches and Controls
Alarm Horn. Horn sounds if any fault or anticipatory
conditionexists. Placethe generatorset masterswitch
in the AUTO position before silencing alarm horn. See
Controller Resetting Procedure later in this section.
Alarm Silence. Switch disconnects alarm during
service (place the generator set master switch in the
AUTO position before silencing alarm horn). Restore
alarm horn switches at all locations (controller, remote
annunciator, and audio/visual alarm) to normalposition
after fault shutdown is corrected to avoid reactivating
alarmhorn. SeeControllerResettingProcedurelaterin
this section.
GeneratorMasterSwitch(RUN/OFF-RESET/AUTO).
Switch functions as controller reset and generator set
operation switch. Refer to Starting, Stopping, and
Controller Resetting Procedure later in this section.
Lamp Test. Switchtests thecontrollerindicatorlamps.
Selector Switch. Switch selects generator output
circuits to measure. When switched to a position with
three circuit lead labels, amperage is measured on the
upper leadand voltageis measured between the lower
two leads. AC ammeter and voltmeter do no register
with switch in the OFF position.
Voltage Adjustment Potentiometer. Fineadjustment
(±5%) for generator output voltage. See Wiring
Diagrams, Voltage Reconnection.
Fuses and Terminal Strip
Fuses. Fuses are located on controller circuit board.
D 3-amp Remote Annunciator (F1). Fuse
protectsremote annunciator circuit, A/V alarm,
and isolated alarm kit (if equipped).
D 3-amp Controller. Fuse protects controller
circuit board, speed sensor, and lamp circuit
board.
D 15-amp Engine and Accessory. Fuse
protects engine/starting circuitry and
accessories.
Controller TB1 Terminal Strip (on Circuit Board).
Connectgeneratorset accessories suchasemergency
stop switch, remote start stop/switch, audio/visual
alarms, etc., to the TB1 terminal strip. Make crank
mode selection (cyclic or continuous) on the TB1
terminalstrip. Figure 2-2shows thelocationof theTB1
terminal strip on the controller circuit board. Refer to
appropriate wiring diagrams for additional information
on connecting accessories to the TB1 terminal strip.
