x series with advance micro - Sunbelt Transport Refrigeration

2.2 GENERAL DESCRIPTIONThe refrigeration units described in this manual areone-piece, self-contained, fully charged, pre-wired,refrigeration/heating nosemount diesel powered unitsfor use on insulated trailers or rail cars to maintain cargotemperatures within very close limits.Automatic evaporator coil defrosting is initiated by eithersensing the air pressure drop across the coil with a differentialair switch or with the defrost timer in the microprocessor.The control box includes manual switches, microprocessor,fuses, and associated wiring. The unit can beequipped with an optional remote light bar which mountsseparately on the front roadside corner of the refrigeratedcompartment.The temperature controller is a solid state microprocessor(Refer to Section 2.5). Once the microprocessoris set at the desired temperature, the unit will operateautomatically to maintain the desired temperature withinvery close limits. The control system automatically selectshigh and low speed cooling or high and low speedheating as necessary to maintain the desired temperaturewithin the refrigerated compartment.The auto Start--Stop operation provides automatic cyclingof the diesel engine, which in turn offers an energyefficient alternative to continuous operation of the enginewith control of temperature by alternate cooling andheating of the supply air (evaporator outlet air). The autoStart--Stop feature is standard equipment.62-106832--2
