CONDENSER MOTOR OVERHEATED
• ACTIVATION: The condenser fan motor Internal Protectors (IP-CDM1) circuit is open,
and
AL00013
(High Discharge Pressure) is not active.
• UNIT CONTROL: Engine Operation: Engine and unit shutdown and alarm.
Electric Operation: Refrigeration system shutdown and alarm with PSCON still ener-
gized.
• RESET CONDITION: Auto Reset when motor overload input is within limits, or change to engine Opera-
tion, 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.
CORRECTIVE ACTIONS:
1.
Check Condenser Fan Blades for Free Operation
Visually inspect condenser fan blades for any foreign material or damage or anything that will prevent
the blade and motor from turning freely Fan blade must be in good condition. No sticks or other mate-
rial obstructing it’s movement No ice build-up preventing blade rotation.
2.
Determine if the IP is open
a. Check for Continuity between 1CCB33 and 1CCB02. It should be 0 Ohms. If condenser fan motor
is extremely warm, allow it to cool off, then recheck IP continuity.
b. If open, continue with step 6 below.
3.
Check Fuses
Check fusesF9, F36, F37 and F38. Verify correct fuse, and check fuse holder for damage, see
. Replace fuse(s) as required. Clear alarms, restart and check for repeat alarm(s).
4.
Check Condenser Fan Motor Contactor
a. Inspect the wire connections to the contactor. (See wiring schematic
.) No signs of
overheating of the contactor. Wiring is routed correctly to the contactor.
b. Check tightness of the contactor wire connections. Tighten with screwdriver and check for discol-
oration of wires.
5.
Perform Pretrip
Clear Active Alarm list, then run Pretrip & check for any new alarms. Any active alarms must be cor-
rected and cleared before proceeding.
6.
Check Condenser Fan Motors
Disconnect power plug at motor. Test IP circuit for continuity using ohmmeter. If IP remains open
after a 30 minute cool down period, and motor feels cool to the touch, remove and replace motor.
Refer to
If closed, then an intermittent IP circuit is suspect. Check phase to phase and phase to ground for
short or open circuits. Refer to
for correct electrical values.
If motor tests good, check the DC IP circuit to microprocessor.
