The code display is CD17. The data will bedisplayed with one decimal place and the proper unitdesignator, Degree C or Degree F (i.e. 3RA85.0F).Maintenance Hour Meter 1The maintenance hour meter 1 setting is displayed withthe description MHR1 or CD18. The maintenance hourmeter is compared to one of the hour meters (diesel,standby, or switch on) determined by its mode. If the hourmeter is greater than the maintenance hour meter analarm will be generated.Maintenance Hour Meter 2The maintenance hour meter 2 setting is displayed withthe description MHR2 on the left side or CD19. Themaintenance hour meter is compared to one of the hourmeters (diesel, standby, or switch on) determined by itsmode. If the hour meter is greater than the maintenancehour meter an alarm will be generated.Switch On Hour MeterThenumberofswitchonhoursisdisplayedwiththedescription SON or CD20 (i.e. SON 2347H or CD202347H). The display range is 0 to 99999.1-23 62-02461
1.1.1 HEAT/COOL MODE1.10.7ALARM DISPLAYThe fault light (FL) is turned on only for alarms thatspecify it. The default display will be overridden if a alarmis generated. When an alarm is generated, the display willalternate the default display (setpoint/air temperature)and the active alarm(s). Each item will be displayed for 3to 10 seconds, and will continue to scroll through the list.See section 1.10.5 for the procedure on resetting alarms.Table 1-7.

This alarm is generated ifthe control senses low oil pressure under the properconditions. The fault light (FL) is turned on. Engine willshut down.High Coolant Temperature AlarmThe high coolant temperature alarm is displayed with thedescription ENG HOT or AL1. This alarm is generated ifthe control senses a high coolant temperature 230 to240_F (110 to 116_C) for 5 minutes or immediately ifover 240_F (116_C). The fault light (FL) is turned on andengine will shut down.High Pressure AlarmThe high pressure alarm is displayed with the descriptionHI PRESS or AL2. This alarm is generated if the highpressure switch opens. The fault light (FL) is turned onand engine will shut down.Start Failure AlarmThe start failure alarm is displayed with the descriptionSTARTFAIL or AL3. This alarm is generated if theengine fails to start. The fault light (FL) is turned on.If function MAN OP (manual start mode) is selected thestart failure alarm will be generated if the engine fails tostart in 5 minutes.Low Battery Voltage AlarmThe low battery voltage alarm is displayed with thedescription LOW BATT or AL4. This alarm is generatedif the battery voltage falls below 10 vdc. The fault light(FL) is turned on and engine will shut down.High Battery Voltage AlarmThe high battery voltage alarm is displayed with thedescription HI BATT or AL5. This alarm is generated ifthe battery voltage is above 17 vdc. The fault light (FL) isturned on and engine will shut down.Defrost Override AlarmThe defrost override alarm is displayed with thedescription DEFR FAIL or AL6. This alarm is generatedif the unit is in a defrost override mode (See Section1.10.10).Alternator Auxiliary AlarmThe alternator auxiliary alarm is displayed with thedescription ALT AUX or AL7. This alarm is generated ifthe alternator auxiliary signal is not present with theengine running. (See Section 1.10.11) The fault light (FL)is turned on.Starter Motor AlarmThe starter motor alarm is displayed with the descriptionSTARTER or AL8. This alarm is generated if the startermotor input signal is not present with starter solenoidenergized. The fault light (FL) is turned on.ReturnAirSensorAlarmThe return air sensor alarm is displayed with thedescription RA SENSOR or AL9. This alarm isgenerated if the return air sensor is open or shorted. Thefault light (FL) is turned on if the unit shuts down becausethere is no controlling probe.Supply Air Sensor AlarmThe supply air sensor alarm is displayed with thedescription SA SENSOR or AL10. This alarm isgenerated if the supply air sensor is open or shorted. Thisalarm will be disabled if the REM PROBE is selected inthe controlling probe functional parameter.62-024611-24
