SAFETYYour Carrier Transicold refrigeration unit has been designed withthe safety of the operator in mind. During all pre-trip inspections,daily inspections, and problem troubleshooting, you may beexposed to moving parts; please stay clear of all moving parts whenthe unit is in operation and when the Start/Run-Off Switch is in theSTART/RUN position.AUTO-STARTYour refrigeration unit is equipped with Auto-Start in both Start/Stopand Continuous Run modes. The unit may start at any time, abuzzer will sound for 5 seconds before the unit is started. Whenperforming any check of the refrigeration unit (e.g., checking thebelts, checking the oil), make certain that the Start/Run-Off Switchis in the OFF position.ENGINE COOLANTThe engine is equipped with a pressurized cooling system. Undernormal operating conditions, the coolant in the engine and radiatoris under high pressure and is very hot. Contact with hot coolant cancause severe burns. Do not remove the cap from a hot radiator; ifthe cap must be removed, do so very slowly in order to release thepressure without spray.REFRIGERANTSThe refrigerant contained in the refrigeration system of your unitcan cause frostbite, severe burns, or blindness when in directcontact with the skin or eyes. For this reason, and because oflegislation regarding the handling of refrigerants during systemservice, we recommend that, whenever your unit requires serviceof the refrigeration system, you contact your nearest CarrierTransicold authorized repair facility for service.BATTERYThis unit is equipped with a lead-acid type battery. The batterynormally vents small amounts of flammable hydrogen gas. Do notsmoke when checking the battery. A battery explosion can causeserious physical harm and/or blindness.162--10601

UNIT IDENTIFICATIONEach unit is identified by a decal attached to the frame of the unit.This decal is on the roadside vertical frame post behind theroadside side door. This decal identifies the complete modelnumber of the unit, the serial number, the refrigerant charge andquantity, and the date the unit was placed in service.If a problem occurs, please refer to the information on this decal,and make a note of the model and serial number before calling forassistance. This information will be needed when you contact atechnician or Carrier Transicold Service Engineer so that they mayproperly assist you.62--106012

The microprocessor controller will run a self test. All of the modelights will light, all of the segments on the display will be turned on.The display will then show the setpoint temperature on the left andthe box temperature of the trailer on the right. The last character(after the degree symbol) shows the temperature units as F(Fahrenheit) or C (Celsius).If the unit is in Auto Start/Stop mode or Continuous Run/AutoOperation mode, the glow plugs will energize, the buzzer willsound, and the diesel engine will start.If the unit is set for Continuous Run/Manual Operation mode, theunit must be started manually.WARNINGUnder no circumstances should ether or any otherstarting aids be used to start engine.The microprocessor controller monitors box temperature, batteryvoltage, and engine coolant temperature. Once the setpoint isreached the controller will shut off the diesel engine to conservefuel. The controller will not shut off the engine if the battery voltageis not sufficient to restart it.The controller will restart the engine if any of the following criteriahave been met:SBox temperature has changed by 11 F ( 6.1 C)for setpointsin the perishable range and 11 F ( 6.1 C) for setpoints in thefrozen range DURING minimum off time.SBox temperature has moved away from setpoint by 3.6 F(2.0 C) AFTER minimum off time for setpoints in the perishablerange or 3.6 F (2.0 C) for setpoints in the frozen range.SThe battery voltage drops below 11 Vdc (12.2 Vdc for units withEEPROM Rev 3.25 and higher -- Refer to Page 21 for unit data).SThe engine coolant temperature drops below 34 F (1 C).562--10601

The PRETRIP mode is for checking unit operation and evaluatingoperation of all modes. The unit will cycle thru all modes ofoperation at 30 second intervals. When Pretrip is complete, Pretripmode is terminated and the unit returns to normal operation.The final PRETRIP mode is Defrost. When Defrost ends,PRETRIP will be complete.This is not a self-diagnosing pretrip test. No specific pretrip alarmswill be generated. Pretrip must be monitored by the user to verifythat the unit operates through all cycles.See Page 28 for more information on Pretrip.962--10601

Setpoints of -22 F to 89 F (-30 C to 32 C) may be entered viathe keypad. The controller always retains the last entered setpointin memory. If no setpoint is in memory (i.e. on initial startup), thecontroller will lock out the run relay and flash “SP” on the left handdisplay until a valid setpoint is entered. The setpoint may bechanged up or down in 1 increments by pressing and releasingeither the UP ARROW or DOWN ARROW key.You can not change setpoint when unit is in Pretrip or when viewingUnit Data or Functional Parameters.Pressing the ENTER key will cause the new displayed setpointvalue to become active. If the display is flashing and the new valueis not entered, after 5 seconds of no keyboard activity, the displaywill flash for 5 seconds and then revert back to the last setpoint.All other keys are active at this time and may be pushed while thedisplay is flashing.1162--10601

START-STOP .0 34.5 FSETPOINTSTANDBYPOWER ONBOX RETRIPCHECKAUTO S/SCONTINUOUSMANUALDEFROSTOFFSTANDBYENGINE1. Press the AUTO S/S-CONTINUOUStoggle key until START-STOP isdisplayed. Unit is now in AutomaticStart/Stop mode.Automatic start/stop is provided to permit starting/restarting of thediesel-driven compressor as required. This gives themicroprocessor automatic control of starting and stopping thediesel engine. The main function of automatic start-stop is to turnoff the refrigeration system near the setpoint to provide a fuelefficient temperature control system and then restart the enginewhen needed. Start-Stop operation is normally used for frozenloads. Refer to RECOMMENDED TRANSPORT TEMPERATURES (See Page32).62--1060112

The unit will remain in low speed after engine start-up - 5 minutesfor XT products, 10 minutes for all others. If the unit fails to start,shuts down on a safety, or fails to run for the minimum run time,three consecutive times, the fault light is on.Low speed Start--up for low coolant temperatures is available onConfiguration 7 for all units except those with EEPROM REV 3.23and 3.24 -- Refer to Page 21 for unit data.The microprocessor controller monitors box temperature, batteryvoltage, and engine coolant temperature.Whenever the unit starts in Start--Stop, it will run until:SIt has run for the predetermined minimum run time.SThe engine coolant temperature is above 122 F (50 C)SThe box temperature is at setpoint.The controller will not shut off the engine if the battery voltage is notsufficient to restart it. Battery voltage above approximately 13.4volts is required for shutdown. This varies depending on ambient.Look at battery voltage in data list to find out whether shutdownvoltage has been reached. If there is a “ ” in front of the number,the voltage is enough to shutdown and restart. If only the numberappears, the voltage is still too low for shutdown.The controller will restart the engine if any of the following criteriahave been met:SBox temperature has changed by 11 F ( 6.1 C)for setpointsin the perishable range and 11 F ( 6.1 C) for setpoints in thefrozen range DURING minimum off time.SBox temperature has moved away from setpoint by 3.6 F(2.0 C) AFTER minimum off time for setpoints in the perishablerange or 0.5 F (0.3 C) for setpoints in the frozen range.SThe battery voltage drops below 11 Vdc (12.2 Vdc for units withEEPROM Rev 3.25 and higher -- Refer to Page 21 for unit data).SThe engine coolant temperature drops below 34 F (1 C).1362--10601
