2-4 Operation
TP-5631 7/96
Switches and Controls
Alarm Horn.
Horn sounds if any fault or anticipatory
condition exists. Place the generator set master switch
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 normal position
after fault shutdown is corrected to avoid reactivating
alarm horn. See Controller Resetting Procedure later in
this section.
Generator Master Switch(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.
Switch tests the controller indicator lamps.
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 lead and voltage is measured between the lower
two leads. AC ammeter and voltmeter do no register
with switch in the OFF position.
Voltage Adjustment Potentiometer.
Fine adjustment
(
±
5%) for generator output voltage.

Diagrams, Voltage Reconnection.
Fuses and Terminal Strip
Fuses.
Fuses are located on controller circuit board.
D
3-amp Remote Annunciator (F1).
Fuse
protects remote 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).
Connect generator set accessories such as emergency
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
terminal strip. Figure 2-2 shows the location of the TB1
terminal strip on the controller circuit board. Refer to
appropriate wiring diagrams for additional information
on connecting accessories to the TB1 terminal strip.
