HIGH COOLANT TEMPERATURE
•
TRIGGER–ON: If system in engine mode: For ambient temperatures below 120
°
F (48.9
°
C) Engine
coolant temperature is above 230
°
F (110
°
C), or Ambient temperatures above 120
°
F (48.9
°
C), engine
coolant temp is over 241
°
F (116
°
C), or Engine coolant temperature is between 230
°
F and 241
°
F
(110
°
C and 116
°
C) for more than 5 minutes
(110
°
C and 116
°
C) for more than 5 minutes.
•
UNIT CONTROL: Engine operation: Engine and unit shutdown and alarm. Standby operation: This alarm
will not activate in standby operation.
•
RESET CONDITION: Auto Reset after 15 minutes if the engine coolant temp falls below 212
°
F (100
°
C),
or alarm may be manually reset via keypad or by turning the unit off, then back on again.
NOTE: Follow the steps below until a problem is found. Once a repair or correction has been made, the active alarm
should clear itself (see reset condition above). Operate the unit through the appropriate modes to see if any active
alarm occurs. Continue with the steps below as necessary.
1.
Check Coolant Level
a. Check coolant level in overflow bottle Level must be in the Normal range.
b. Check coolant level in radiator
Do not remove the cap from a hot
radiator; if the cap must be removed,
do so very slowly in order to release
the pressure without spray.
Level must be at the top of the radiator fill tube.
c. Inspect connecting tube between
overflow bottle and radiator
Connections must be airtight. No leakage or holes in tube.
2.
Check For Bad Eng Coolant Sensor Alarm
a. Check for Alarm 129
Alarm conditions must be corrected and the alarm cleared
to continue
3.
Check Freeze Point Of Coolant
a. Use Coolant Tester to check
concentration of anti-freeze mixture.
Must be between 40% to 60% Ethylene Glycol to water
mixture.
4.
Check Airflow Through Radiator / Condenser Coil
a. Inspect condenser/ radiator fins
Fins must be straight. 90% or more of the coil surface
must be undamaged. No “dead” air spaces. Condenser /
Radiator coil must be clean.
b. Check condenser fan rotation /
operation
Fans should operate correctly. Air should be directed in
through the grill, and into the engine compartment.
5.
Check Water Pump Belt
a. Check engine water pump belt.
No Glazing, no cracking, no slipping
6.
Check Engine Cooling System
a. Compare actual engine temperature to
the microprocessor reading
Temperature must be within
±
20
°
F (
±
11.1
°
C).
b. Test operation of engine coolant
thermostat
Must operate correctly
c. Check water pump operation
No seepage at weep hole. Bearings tight and quiet.
Impeller firmly attached to shaft.
d. Check water pump bypass hose to
thermostat
housing
for
internal
blockage
Must be clear and open
