Before the next starting sequence, the oil pressure ischecked to determine if the engine is running and thealternator auxiliary has failed. For the second and thirdstart attempts the glow time is increased by 5 secondsover the glow time of the first attempt listed below. Thecontrol allows three consecutive start attempts beforethe starting is locked out and the start failure alarm isactivated.REPEAT “A”+ 5 SecondsGLOW15 SecondsSTOPREPEAT “A”+ 5 SecondsGLOW15 SecondsSTOPMAXIMUM10 SecondsChecked at2 SecondsCRANKVARIABLE0to30SECONDSGLOWGLOWTHIRDATTEMPTSECONDATTEMPTFIRSTATTEMPT “A”Figure 1-20.

The glow timecan be manually overridden through the functionparameters. If the coolant temperature sensor isdefective the control assume a temperature of less than32_F (0_C) for the glow timing.g. Minimum On TimeThe engine is allowed to turn off only after a minimum of4 or 7 minutes of run time with software revision less than3.11. With software revision 3.11 or higher the on-time is4minutes.After the minimum on-time, the unit will go to fullyloaded for setpoints greater than 10_F ( --- 12_C) and highspeed loaded for setpoints of 10_F ( --- 12_C) or less.The unit will not cycle off if the engine coolanttemperature is less than 122_F (50_C) or the battery isnot good. If the unit can not cycle off, it will operatenormally in continuous mode. If all temperature probesfail and the setpoint is 10_F ( --- 12_C) or less, the unit willnot shut down.The unit will shut down when the box temperature iswithin ¦0.5_F(¦0.3_C) of setpoint for setpoints in thePerishable range or +0.5_F (+0.3)abovesetpointforsetpoints in the Frozen range.h. Minimum Off-TimeKeypad provision is provided to select the minimumoff-time of 10, 20, 30, 45 or 90 minutes.After the minimum off-time, the unit will restart fortemperatures beyond ¦3.6_F (¦2.0_C) of setpoint forthe Perishable range or above +3.6_F (+2.0_C) ofsetpoint for the Frozen range.The minimum off-time is overridden if the temperatureis more than ¦11_F (¦6_C) from setpoint.i. Battery VoltageProvisions are made to sense when the battery is good. Agood battery is defined as having 13.4v at 75_F. Thiscondition is used to allow shut- off of the diesel engine.1-27 62-02461
1.1.1 HEAT/COOL MODEIf the battery voltage falls below 10v during glow cycle, thestarter will not engage and the start sequence willcontinue, this is considered a failed start. The startsequence will be repeated until the unit starts or threeconsecutive start attempts have failed.MessageDisplayLOWBATTAL4HI BATTAL5Table 1-8.

Oil Pressure SignalWhen the oil pressure switch is closed it shows that theengine is running and prevents engagement of the startermotor when operating in the auto mode.k. Maximum Off-TimeProvision for a keypad selectable feature is providedwhich will cause the engine to be started 30 minutes afterthe engine has stopped regardless of the boxtemperature.1.10.12 Remote Monitoring - DataTrak (Optional)The microprocessor controller is equipped with a RS232communication port. This port can be used tocommunicate unit operating data to a mobile satellitetransmitter. This information will then be relayed back tothe office via a modem to a computer.There are presently three (3) protocols supported. Theprotocol for the QualComm transmitter, the protocol forthe HUGHES transmitter, and Carrier CommunicationProtocol. The microprocessor will power up and transmita HUGHES protocol packet and continue to transmit apacket every hour. The microprocessor will transmit inthe Carrier, QualComm protocol if a data packet isrequested.1.11 SWITCHES AND CONTROLS1.11.1 IntroductionComponents required for monitoring and controlling thediesel engine --- refrigeration system are located in thecontrol box door and relay module. The watertemperature sensor is located on top of the engine.1.11.2 Control Box Door and Relay Module(See Figure 1-10 and Figure 1-11)a. Gauges1. Ammeter Gauge (A)The d-cammeter indicates the rate of charge or dischargeof the battery charging system (including batteries),battery charging alternator and the voltage regulator.b. Switches1. Run-Stop Switch (RS)When placed in the RUN position, this switch providespower to the microprocessor. The microprocessorperforms a self-test (all segments of display areilluminated). Then Set Point and Box Temperature aredisplayed.To stop the unit or remove power from themicroprocessor, move the run-stop switch to the STOPposition.2. Manual Glow/Crank Switch (MGC)The manual glow/crank switch when held in the GLOWposition, energizes (approximately 7.5 amps per plug at12 vdc) the glow plugs in the engine to pre-heat thecombustion chamber. The CRANK position of the switchis used to manually engage the engine starter.3. Selector Switch (SSW) ---Model NDMThis switch is used to select mode of operation, eitherengine drive or standby electric motor drive. When thisswitch is placed in standby position, the electric motorwill not start until the oil pressure safety switch (OP)opens.1.11.3 Location of Engine Safety Devicesa. Oil Pressure Safety Switch (OP)This switch, set to open below 15 ¦ 3 psig (1.0 ¦ 0.2kg/cm@), will automatically stop the engine upon loss ofoil pressure. See Figure 1-6 for location.b. Water Temperature Sensor (WTS)This sensor senses engine water temperature. Themicroprocessor will stop the unit when this temperatureexceeds 230_F (110_C). If ambient temperature sensor(ATS) is at 120_F (49_C) or higher, the WTS limits areincreased to 230 to 240_F for 5 minutes or immediatelyover 240_F (116_C). The sensor is located near thethermostat housing in the cylinder head.1.12 ULTRAFRESH 2 TEMPERATURE CONTROLUltraFresh 2 temperature control algorithm is a methodof producing a reduced capacity state between heat andcool modes. This is done by combining a null pulse witheither heat or cool. The capacity in this band can vary byadjusting the duty cycle of the null portion of operation.During this null operation heat and cool valves areopened simultaneously to reduce heating or coolingcapacity.UltraFresh 2 temperature control uses both supply andreturn air sensors to achieve control. If both probes arepresent and neither is defective or out of range theselected probe is the active probe. The controlling probe62-024611-28
