Steps
ALARM / CAUSE
CORRECTIVE ACTION
91
CHECK HEATER CONTACTOR 1
•
TRIGGER–ON: Heater Contactor 1 Relay (HTCON1R) coil current is more 5 Amps
•
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.
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 HTCON1R
a. Inspect heater 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 HTCON1R 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 HTCON1R 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

1.
Check HTCON2R
a. Inspect heater contactor coil and
terminals
No damage to coil
No damaged or corroded pins
b. Check contactor coil resistance
