•
UNIT CONTROL: Engine and standby operation: alarm only
•
UNIT CONTROL: Engine and standby operation: alarm only.
•
RESET CONDITION: Auto Reset or alarm may be manually reset via keypad or by turning the unit off,
then back on again.

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 2HTCON1
a. Inspect heater contactor 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 2HTCON1 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 HTCON1 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
