DIESEL GENERATOR SETS
3.1 Dole Fleet Overview
Diesel generator sets used in the Dole fleet are provided by several different manufacturers
including Carrier Transicold, Taylor Power Company and Thermo King. These under-
mounted diesel-driven generators are similar in operation and design and provide a constant
electrical power supply for the container’s refrigeration unit. They are powered by a four-
cylinder, in-line diesel engine which drives a 15 kw, A/C generator. The generator produces
a constant 460 vac, 3 phase, 60 hertz electrical source. They are equipped with a 12 volt D/C
battery charging alternator system which maintains battery amperage for engine start, glow
plug operation, and other accessory operation.
System components are protected from damage caused by unsafe operating conditions
through the use of automatic shut down safety devices. These shut down devices are
automatically activated under the following conditions: low engine oil pressure, high engine
coolant temperature and excessive current draw.
It is the driver’s responsibility to ensure that the diesel generator set is operated correctly and
that daily operator maintenance is properly performed. This section of the manual deals with
diesel generator pre-trip procedures, operation instructions, daily maintenance and
troubleshooting.
3.2 Pre-Trip Inspection Procedures
The following pre-trip procedures are common to all makes of diesel driven generator sets
found in the Dole fleet. The below listed items are to be checked PRIOR to starting the unit.
a) Check for leaks: determine the cause of any leak from the lubrication, fuel or cooling
systems. Have repairs made as appropriate.
b) Check engine oil
c) Check engine coolant level at coolant expansion tank.
d) Check diesel fuel supply.
e) Check engine V-belt for wear and proper tension.
f) Check for loose electrical connections.
g) Check for any physical damage to the unit.
3.3 Starting the Diesel Generator Set
Instrumentation and controls vary slightly between the various generator models used by
Dole, however starting procedures are essentially the same. The following steps are to be
followed in starting the under-mounted diesel generator set:
