  • Page 9: Safety Summary

    SECTION 1 SAFETY SUMMARY GENERAL SAFETY NOTICES Installation and servicing of Genset equipment can be hazardous due to system belts, radiator fan, and electrical components. Only trained and qualified service personnel should install, repair, or service Genset equipment. When working on Genset equipment, observe all potential Danger, Warning and Caution hazards, including those shown below and on hazard labels attached to the unit.

  • Page 10: Specific Hazard Statements

    SPECIFIC HAZARD STATEMENTS The statements that follow are applicable to the generator set and appear elsewhere in this manual. These recom- mended precautions must be understood and applied during operation and maintenance of the equipment covered herein. WARNING Beware of moving poly V-belt, belt driven components and hot exhaust components. WARNING Under no circumstances should ether or any other unauthorized starting aids be used in con- junction with the air intake heater.
  • Page 11 CAUTION Use only ethylene glycol, anti-freeze (with inhibitors) in system. Use of glycol by itself will dam- age the cooling system. CAUTION Never open the radiator cap when the coolant is hot. CAUTION Always cover the engine inlet tube while the air cleaner is being serviced. CAUTION Do not underfill or overfill the oil bath cups.

  • Page 13: Description

    SECTION 2 DESCRIPTION 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 Figure 2.6) consists of a diesel engine direct-connected to an alternating current generator and mounted in a structural steel frame.

  • Page 27: Safety Devices

    SAFETY DEVICES Safety devices, such as circuit breakers, fuses, and safety switches protect system components from damage. The AC generator, solid state battery charger, fuel heater, high water temperature, safety relay, total time meter and intake heater are protected by circuit breakers. If a safety device opens and there is an interruption of electrical current, the electronic governor module will be de-energized, which will also de-energize the fuel solenoid, interrupt the fuel flow to the engine and stop the engine.

    d. With the intake heater switch held in the PREHEAT position, place the ignition switch in the START position. e. After the engine has started, continue to hold the intake heater switch in the PREHEAT position until the engine develops sufficient oil pressure to close the oil pressure safety switch (approximately 5 seconds). When released, the intake heater switch will automatically return to the OFF position and the heater will remain energized for 3 minutes.
  • Page 35 2. Units with Auto Start, Low Coolant Sensor: When the ignition switch (IGN) is placed in the RUN position, 12-volt DC power is applied to the low coolant sensor (LCS), if applicable, and the auto restart module simultaneously. If the coolant level is below the sen- sor, all the indicator lights on the auto restart module will blink once and the LCS will open the contacts on the low coolant relay, de-energizing the unit’s 12-volt DC circuitry.
