Steps
ALARM / CAUSE
CORRECTIVE ACTION
P206 CHECK CONDENSER FAN CIRCUIT
TRIGGER-ON: Normal amps for the CDCON contactor coil are 0.05 to 2.0 Amps (12 VDC). The
circuit tests outside this range.
UNIT CONTROL: Engine and standby operation: Pretrip will fail and display "PRE-TRIP FAIL AND
COMPLETED".
RESET CONDITION: Auto Reset if Pretrip is started again, or alarm may be manually reset via key-
pad 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, clear the
alarm(s).
See Note 1
Page 7-1.
Operate the unit through the appropriate modes to see if any active alarm occurs.
Continue with the steps below as necessary.
1
Check CDCON
a. Inspect CDCON contactor coil and
wire connections.
No damage to coil.
No damaged or corroded pins.
b. Check contactor coil resistance.
Refer to Section 2.12.
2
Check CDCON Amp Draw
a. Check CDCON contactor coil amp
draw.
Use Component Test Mode (Section 5.1.2) to test.
Refer to Section 2.12 for amp values. View current
draw in Data List.
3
Check CDCON Wiring
a. Inspect harness & control box
connector pins & terminals. (See
wiring schematic Section 10.)
See Note 2 & Note 5 on Page 7.2
.
No physical damage to harness.
No damaged or corroded pins.
P207 CHK COMPRESSOR CONTACT CIRC
TRIGGER-ON: Normal amps for the CCONR and CCON relay coils are 0.0 to 1.0 Amps (12 VDC).
The circuit tests outside this range.
UNIT CONTROL: Engine and standby operation: Pretrip will fail and display "PRE-TRIP FAIL AND
COMPLETED".
RESET CONDITION: Auto Reset if Pretrip is started again, or alarm may be manually reset viakey-
pad 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, clear the
alarm(s).
See Note 1
Page 7-1.
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 CCONR and CCON con-
tactor coils and wire connections.
No damage to coil.
No damaged or corroded pins.
b. Check contactor coil resistance
Refer to Section 2.12.
2
Check CCONR Amp Draw
a. Check CCONR and CCON contac-
tor coil amp draw.
Use Component Test Mode (Section 5.1.2) to test.
Refer to Section 2.12 for amp values. View current
draw in Data List. FET 2 On.
b. Listen for CCON to pull in.
If CCON contactor pulls in, CCONR and CCON are
OK.
If CCON contactor does not pull in, check for voltage at
CCON coil. 12 VDC indicates defective CCON coil. No
voltage - check CCONR.
3
Check CCONR Wiring
a. Inspect harness & control box
connector pins & terminals. (See
wiring schematic Section 10.)
See Note 2 & Note 5 on Page 7.2
.
No physical damage to harness.
No damaged or corroded pins.
