General Description
Thermo King generator sets (clip-on, under-mount and flexi mount) are self-contained fully-automatic, diesel powered units. The generator sets supply 230 or 460 Vac electrical power for container refrigeration units. Enclosed within the unit frame are the engine, dual voltage alternator, generator battery compartment, battery charging regulator and control panel.
- Caution
- Risk of Injury
- DO NOT attempt to operate or maintain the generator until you have completely familiarized yourself with the equipment.
This unit uses an engine called TK486VGE1 (EPA Tier IV and 2016/1628 EU regulation (or NRMM Stage V) compliant). This is a 4-cylinder, water cooled, direct injection diesel engine. An ECU (Engine Control Unit) monitors and controls engine operation. The unit controller indirectly monitors and controls the engine through the ECU.
Each unit features a welded, heavy-gauge steel frame with special sea-going finish; non-corrosive fittings, all stainless steel external hardware, brazed aluminum radiator, and poly-vinyl coating on the engine and generator.
Fuel tanks are provided as an integral part of each unit except SGFM flexi mount models. Fuel capacities are: 454 liter (120 gal.) on SGCO clip-on models; 303 liter (80 gal.), 189 liter (50 gal.) or 114 liter (30 gal.) on SGUM under mount models.
The alternator is a brushless, rotating field ac generator. A rectified exciter armature output provides dc power for the field. The exciter field obtains its power from the full wave rectified output of the main generator. The alternator supplies 230 or 460 Vac, 3 phase, 4 wire, 60 Hz power at 1800 RPM.
This equipment develops normal output voltages (below 600 volts) whenever the engine is running. All output voltages normally reach 460 volts. Under malfunction conditions, 575 volts may be produced. Any electric potential more than 50 volts is hazardous. Exercise caution and discretion in the operation and maintenance of the equipment.
