•
TRIGGER–ON: The Remote Fan (3rd compartment) input is outside limits AND not cranking the engine
and RS is on.
•
UNIT CONTROL: Engine and standby: Compartment 3 shutdown only
•
RESET CONDITION: Auto Reset or alarm may be manually reset via keypad or by turning the unit off,

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 Compartment 3 Evaporator Motor Contactor
a. Inspect the three contacts behind the
top cover
If the contactor buttons are blue due to chattering caused
by a defective IP, replace the contactor.
b. Check tightness of the contactor wire
connections
Tighten with screwdriver and check for discoloration of
wires.
2.
Check Motor Operation
a. Turn the unit ON
Check current on each phase (must be less than shown
on Section 2.13).
Check voltage on each phase (must be at least 440VAC).
3.
Check Compartment 3 Evaporator Motor
a. Disconnect power plug at motor
Test IP circuit for continuity using ohmmeter
If open, remove and replace motor
If closed, then an intermittent IP circuit is suspect. Check
phase to phase and phase to ground for short or open
circuits See Section 2.13.
If motor tests good, check the DC IP circuit to
microprocessor.
4.
Perform Pre--trip Check
a. Run pre--trip & check for alarms
Any active alarms must be corrected and cleared before
proceeding.
