RESET CONDITION: Auto Reset 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 Suction Temp Sensor
a. Inspect Suction Temp Sensor &
connector
No damage to sensor
No damage, moisture, or corrosion in connector
b. Check
Suction
Temp
Sensor

2.
Check Suction Temp Sensor Wiring
a. Inspect harness & control box
connector pins & terminals (See
wiring schematic)
No physical damage to harness.
No damaged or corroded pins
128 LOW A/C AMPS
•
TRIGGER–ON: If the compressor is on and AC Current Sensor 1 or 2 is less than 5 amps for 10 seconds
OR If the difference between AC Current 1 and AC Current 2 is greater than 10 amps for 10 seconds

•
UNIT CONTROL: Engine and standby operation: alarm only.
•
RESET CONDITION: Change unit to standby operation when AC Current Sensor 1 and 2 is greater than
7 amps for 5 minutes AND difference between AC Current 1 and AC Current 2 is less than 7 amps for
5 minutes 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.
Perform Pre--trip Check
a. Run pre--trip & check for alarms
Any active alarms must be corrected and cleared before
proceeding.
2.
Check Current Draw
a. Use a clamp around A/C ammeter to
check amps at power wires
Must be
1.0 Amp of reading in Data List.
b. Check A/C amps with compressor
running
Must be greater than 5 Amps.
c. Compare A/C Amp readings between
L1--L2--L3
Maximum allowable difference is 10 Amps.
