CHECK HIGH TEMP THERMOSTAT
•
TRIGGER–ON: With RS in ON position and EVHTS circuit is open.
•
UNIT CONTROL: Alarm AND no heat allowed for any compartment
•
UNIT CONTROL: Alarm AND no heat allowed for any compartment.
•
RESET CONDITION: Auto Reset when temperature is okay for 15 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.
Check High Temperature Thermostat
a. Inspect high temperature thermostat
and connector
No damage to switch
No damage or corrosion in connector
2.
Check High Temperature Contact
a. Contact must be closed when
temperature is normal
Unplug EVHTS and check for continuity
Check for power on SPK5.
Check for power at 4MP4

CHECK STANDBY CONTACTOR
•
TRIGGER–ON: Standby motor contactor relay (PSCONR) current is higher than 2.0 Amps.
•
UNIT CONTROL: Engine and standby operation: alarm only
•
UNIT CONTROL: Engine and standby operation: alarm only.
•
RESET CONDITION: Auto Reset when the PSCONR Coil current (amp) draw is normal, 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 PSCONR
a. Inspect standby contactor relay coil
and terminals
No damage to coil
No damaged or corroded pins
b. Check contactor coil resistance
Cannot be opened (infinite ohms); Shorted (Zero Ohms)
or shorted to ground
c. Check amp draw of coil.
Refer to Section 2.14. Use ammeter.
2.
Check PSCONR Current Draw
a. Use Component Test Mode (Refer to
Section 5.2.5.2.2) to test actual current
draw of the circuit.
Refer to Section 2.14 for normal current values.
View current draw in Data List.
3.
Check PSCONR Wiring
a. Inspect harness & control box
connector pins & terminals (See
wiring schematic)
See Notes 2 & 6
No physical damage to harness.
No damaged or corroded pins
