2.3.5 Engine Screw Threads
All threads used on the engine are metric except for the oil drain plug, which is American Standard Pipe Thread (NPT).
2.4 ALTERNATING CURRENT GENERATOR
The generator is directly bolted to the engine and supplies nominal 50/60Hz power depending on the load requirement.
2.5 BATTERY CHARGING SYSTEM
The solid state battery charger (see Figure 2.2 ) is located in front of the battery. The battery charger is powered by
the generator, and this input is protected by fuses located in the receptacle box. The battery charger produces a
tapered charge (40 amps maximum) and is designed not to overcharge the battery.
CAUTION
!
Observe proper polarity when installing the battery or connecting a battery charger. The nega-
tive battery terminal must be grounded. Reverse polarity may damage the charging system.
When charging the battery in unit, isolate the battery by disconnecting the negative battery ter-
minal first, then the positive. Once the battery has been charged, connect the positive battery
terminal first, then the negative.
2.6 VOLTAGE CONTROLLER
Voltage Controller maintains ISO voltage via two-speed and dual winding control. It is used to regulate voltage in
order to keep the generator output within ISO limits:
50Hz - 1500 RPM, 360 - 460 VAC
60Hz - 1800 RPM, 400 - 500 VAC
2.7 OPERATING CONTROLS & INSTRUMENTS
2.7.1 Introduction
Components required for monitoring and controlling the Genset unit are located in the control box, on the control
panel and on the receptacle box.
2.7.2 Control Panel and Related Components
1. Gauges and Senders
a. Oil Pressure Gauge (see Figure 2.10 )
The purpose of this gauge is to observe normal operating engine oil pressure. Normal oil pressure is 35
to 60 psig (3.3 to 5.2 kg/cm2).
b. Oil Pressure Sender (see Figure 2.9 )
This device senses engine lube oil pressure and transmits a signal to the oil pressure gauge. The oil
pressure sender is located on the oil filter housing.
