WARNING
Beware of moving V---belts and belt driven
components.
This manual contains Operating Data, Electrical
Information, and Service Instructions for the diesel
generator sets shown on table 1---1. (See curb side of unit
for serial/model number plate.)
Separately bound manuals covering the CT4---114
diesel engine for the diesel---driven generator sets are
also supplied, see chart below.

Workshop Manual
The diesel---driven generator sets are intended for
front mounting upon a refrigeration unit. They provide a
constant electrical power supply for the operation of an
all---electric refrigeration unit.
Located inside the frame are the diesel engine, A---C
generator (main alternator), control and monitoring
cabinet, starting battery, 12 vdc battery charging alterna-
tor, regulator and other necessary accessory components
for proper unit operation.
For power, the Carrier Transicold Model CT4---114,
vertical in---line, four cylinder diesel engine is used. The
engine is equipped with glow plugs (used as a starting
aid), “spin---on” lube and fuel oil filters for easier filter
changes.
Electrical power is generated by a Lima 15 KW,
brushless, single bearing A---C generator. The generator
is coupled directly to the engine flywheel. The generator
provides a constant 460 vac, 3 phase, 60 hertz electrical
supply.
The 12 vdc battery charging alternator, water pump
and the radiator cooling fan are belt---driven from the
engine crankshaft sheave.
1.2 SAFETY DEVICES
System components are protected from damage
caused by unsafe operating conditions by automatically
shutting down the diesel engine when such conditions
occur. This is accomplished by the safety devices
HWT,
CB---2
or
OP
. These safety devices monitor system
operating conditions and open a set of electrical contacts
when an unsafe condition occurs. Opening one or more
of these safety switch contacts will de---energize the run
control relay. This, in turn, opens a set of
RCR
contacts to
de---energize the fuel solenoid.
De---energizing fuel solenoid releases the stop---run
lever to the
STOP
position, shutting off the fuel supply to
the engine; thus stopping the engine.
The
A---C
generator and the glow plug circuit are
protected by circuit breakers (listed below) but will not
shut down the engine if an overload occurs.
The 12 vdc battery charging alternator, water pump
and the radiator cooling fan are belt---driven from the
engine crankshaft sheave.
