Alarm
Steps
NO.
P206 CHECK CONDENSER FAN CIRCUIT
•
TRIGGER–ON : Normal draw for the CDCON contactor coil is 0.05 to 2.0 Amps (12 VDC). The cir-
cuit tests outside this range.
•
UNIT CONTROL:
•
RESET CONDITION: Auto Reset if Pretrip is started again, 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, clear the
alarm(s). (See Note 1 page 7−2.) 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.
b. Check contactor coil resistance.
2 Check CDCON Amp Draw
Check CDCON contactor coil amp
draw.
3 Check CDCON Wiring
Inspect harness & control box con-
nector pins & terminals. (See wiring
schematic Section 10.)
P207 CHECK COMPRESSOR CONTACT CIRC
•
TRIGGER–ON: Normal draw for the CCONR and CCON relay coils is 0.0 to 1.0 Amps (12 VDC).
The circuit tests outside this range.
•
UNIT CONTROL:
•
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 7−2.) 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
contactor
connections.
b. Check contactor coil resistance
2 Check CCONR Amp Draw
a. Check CCONR and CCON contac-
tor coil amp draw.
b. Listen for CCON to pull in.
3 Check CCONR Wiring
Inspect harness & control box con-
nector pins & terminals. (See wiring
schematic Section 10.)
Alarm/Cause
Engine and Standby Operation: Pretrip will fail and display

Corrective Action
No damage to coil.
No damage, moisture, or corrosion in connections.
Refer to Section 2.12.
Use Component Test Mode (Section 5.2.2) to test.
Refer to Section 2.12 for amp values. View current
draw in Data List.
No physical damage to harness.
No damage, moisture, or corrosion in connectors.
No damage to coil.
No damage, moisture, or corrosion in connections.
Refer to Section 2.12.
Use Component Test Mode (Section 5.2.2) to test.
Refer to Section 2.12 for correct electrical values.
View current draw in Data List. FET 2 On.
If CCON contactor pulls in, CCONR and CCON are
OK.
If CCON contactor does not pull in, check for 12 VDC
at CCON coil. 12 VDC indicates defective CCON
coil. No voltage - check CCONR.
No physical damage to harness.
No damage, moisture, or corrosion in connectors.
