AL0: Low Oil Pressure Alarm
The low oil pressure alarm is displayed with the des-
cription ENG OIL or AL0. This alarm is generated if the
control senses low oil pressure under the proper condi-
tions. The fault light (FL) is turned on. Engine will shut
down.
AL1: High Coolant Temperature Alarm
The high coolant temperaturealarm is displayedwith
the description ENG HOT or AL1. This alarm is genera-
ted if the controlsenses a high coolant temperature. The
fault light (FL) is turned on and theengine will shutdown.
See Section 2.2.1.
AL2: High Pressure Alarm
The high pressure alarm is displayed with the des-
cription HI PRESS or AL2. This alarm is generated if the
highpressure switch opens. Thefault light (FL) is turned
on and the engine will shut down. See Section 2.4c.
AL3: Start Failure Alarm
The start failure alarm is displayed with the descrip-
tion STARTFAIL or AL3. This alarm is generated if the
engine fails to start. The fault light (FL) is turned on.
If function MAN OP (manual start mode) is selected
the start failure alarmwill be generated if the engine fails
to start in 5 minutes.
AL4: Low Battery Voltage Alarm
The low battery voltage alarm is displayed with the
description LOW BATT or AL4. This alarm is generated
if the battery voltage falls below 10 vdc. The fault light
(FL) is turned on.
AL5: High Battery Voltage Alarm
The high battery voltage alarm is displayed with the
description HI BATT or AL5. This alarm is generated if
the battery voltage is above 17 vdc. The fault light (FL)
is turned on and the engine will shut down.
AL6: Defrost Override Alarm
The defrost override alarm is displayed with the des-
cription DEFR FAIL or AL6. If after 45 minutes of defrost,
the unit is still in defrost mode, the unit displays AL6 and
switches to defrost overide mode. The fault light (FL) is
turned on.
AL7: Alternator Auxiliary Alarm
The alternator auxiliary alarm is displayed with the
description ALT AUX or AL7. This alarm is generated if
the alternator auxiliary signal is not present with the
engine running. (See Section 2.8.12). The fault light
(FL) is turned on.
AL8: Starter Motor Alarm
The starter motor alarm is displayedwith thedescrip-
tion STARTER or AL8. This alarm is generated if the
starter motorinput signal is not present with starter sole-
noid energized. The fault light (FL) is turned on.
AL9: Compartment 1 Return Air Sensor Alarm
The Compartment 1 return air sensor alarm is dis-
played with the description 1RA SENSOR or AL9. This
alarm is generated if the return air sensor is open or
shorted. The fault light (FL) is turned on because there
is no controlling probe.
AL10: Compartment 2 Return Air Sensor Alarm
The Compartment 2 return air sensor alarm is dis-
played with the description 2RA SENSOR or AL10. This
alarm is generated if the return air sensor is open or
shorted. The fault light (FL) is turned on because there
is no controlling probe.
AL11: Coolant Temperature Sensor Alarm
The coolant temperature sensor alarm is displayed
with the description WT SENSOR or AL11. This alarm
is generated if the coolant temperature sensor is open
or shorted.
AL12: Compressor Discharge Temperature Alarm
The compressor discharge temperaturealarm is dis-
played with the description HIGH CDT or AL12. This
alarm is generated if the temperature is sensed above
154
_
C (310
_
F) for three minutes. If the discharge tem-
perature exceeds 177
_
C (350
_
F), the three minute
timer is overridden and the unit shut down immediately.
The fault light (FL) is turned on.
AL13: Compressor Discharge Temperature
Sensor Alarm
The compressor discharge temperature sensor
alarm is displayed with the description CD SENSOR or
AL13. This alarm is generated if the sensor is open or
shorted.
AL14: Standby Motor Overload Alarm
The standby motor overload alarm is displayed with
the description SBY MOTOR or AL14. This alarm is
generated when the MOL input is sensed open with the
Run Relay energized in electric mode (Diesel/Electric
Relay energized).
AL15: Fuse Alarm
The fuse alarm is displayed with the description
FUSE BAD or AL15. This alarm is generated when the
FUSE input is sensed low. The fault light (FL) is turned
on.
