DESCRIPTION
2.1 GENERAL SAFETY NOTICES
The Carrier Transicold model 69UG15 under-mounted diesel-driven generator sets provide electrical power for all-
electric refrigeration units.
The generator set (see Figure 2.2 , Figure 2.4 and Figure 2.6 ) consists of a diesel engine direct-connected to an
alternating current generator and mounted in a structural steel frame. The engine is a vertical in-line, four cylinder
diesel manufactured by Kubota, while the generator is a 15 kW, brushless, dual bearing type. Generator sets will
start at 50Hz. Once the unit is running, the voltage controller will read the voltage output of the generator and
adjust accordingly, to keep the voltage within ISO limits. As the Container becomes loaded, voltage drops and cur-
rent increases, the generator set will switch windings or speed based on power demand and ambient conditions.
The unit will typically run at 50Hz and will vary generator output via winding selection. The speed change to 60 Hz
will typically occur when the ambient temperature is high and the unit is heavily loaded.
Electrical controls are mounted in a control box with operating controls and gauges mounted on a control panel,
which also serves as the control box cover. The control panel components are protected by a deflector assembly
and a windowed control box door.
Auxiliary engine equipment consists of the battery, solid state battery charging system, “spin-on” lube oil filter, fuel
filter and other necessary components for proper unit operation. The water pump and the radiator cooling fan are
belt-driven from the engine crankshaft. All references to engine are as viewed from the fly wheel end.
The 69UG15 is available as a standard configuration, with an Auto Restart option or with Auto Restart and Low
Coolant Sensor. The Auto Restart option automatically restarts the unit in the event of a unit shutdown. Auto
Restart also offers built-in indicators that signal low oil pressure, high water temperature, overspeed, and other
overcrank conditions.
Carrier Transicold’s Ecodriven dual speed option provides an energy saving alternative to the practice of continu-
ously running the generator at full speed. This speed reduction results in increased fuel economy, reduced carbon
footprint, and lowers operating costs.
2.2 CONFIGURATION IDENTIFICATION
Generator set identification information is provided on a label located below the left mounting pad to the left of the
access service door (front facing). The label provides the generator set model number, serial number, and parts
identification number (PID). The model number identifies the overall configuration while the PID provides informa-
tion on specific optional equipment and differences in detailed parts.
The model number, serial number and PID number must be included when ordering parts and inquiring about your
unit.
Separately bound manuals covering the diesel engine are also available (see the following chart).
