CHECK START UP BUZZER
•
TRIGGER–ON: The Buzzer circuit is shorted. (The Buzzer output from the micro is negative, so the
circuit will not be shorted to ground, but is shorted either within the Buzzer itself, or to a
positive wire
positive wire.
•
UNIT CONTROL: Engine and standby operation: alarm only.
•
RESET CONDITION: Auto Reset when Buzzer 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 Buzzer
a. Inspect Buzzer & wire connections
No damage to buzzer
No damaged or corroded pins
b. Check resistance of buzzer
Refer to Section 2.14
2.
Check Buzzer 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
3.
Check Buzzer 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.

CHECK COMP CONTACTOR 1
•
TRIGGER–ON: Compressor motor contactor relay (CCONR) coil current is excessive.
•
UNIT CONTROL: Engine and standby operation: alarm only
•

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 CCONR
a. Inspect compressor 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 CCONR 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
3.
Check CCONR Current Draw
a. Use Component Test Mode (Refer to
Section 5.2.5.2.2) to test actual current
draw of the circuit.
