Alarm
NO.
Steps Alarm/Cause Corrective Action
P208 CHECK GENERATOR CONT CIRC
• TRIGGER–ON: Normal draw for the GENCONR and GENCON coils is 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
“PRETRIP FAIL AND COMPLETED”.
• 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 GENCONR
a. Inspect GENCONR and GENCON
contactor coils and wire connec-
tions.
No damage to coil.
No damage, moisture, or corrosion in connections.
b. Check contactor coil resistance. Refer to Section 2.12.
2 Check GENCONR and GENCON Amp Draw
a. Check GENCONR and GENCON
contactor coils amp draw.
Use Component Test Mode (Section 5.2.2) to test.
Refer to Section 2.12 for amp values. View current
draw in Data List. FET 3 On.
b. Listen for GENCON to pull in. If GENCON contactor pulls in, GENCONR and
GENCON are OK.
If GENCON contactor does not pull in, check for 12
VDC at GENCON coil. 12 VDC indicates defective
GENCON coil. No voltage - check GENCONR.
3 Check GENCONR Wiring
Inspect harness & control box con-
nector pins & terminals. (See wiring
schematic Section 10.)
No physical damage to harness.
No damage, moisture, or corrosion in connectors.
