P00209 CHECK STANDBY CONT CIRCUIT
• ACTIVATION: Normal amps for the PSCON or PSCON2 contactor coils 0.0 to 1.0 Amps (12 VDC). The
circuit(s) test outside this range. (During this test either PSCON or PSCON2 will be tested depending on
the phase reversal module.)
• UNIT CONTROL: Engine and Electric Operation: Pretrip will fail and display “PRETRIP FAIL AND COM-
PLETED”.
• 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). (Refer to Note 1 in Notes Section, page 7-2.) Operate the unit through the appropriate modes to see if
any active alarm occurs. Continue with the steps below as necessary.
NOTE: IF PRETRIP IS DONE IN STANDBY MODE, THIS PRETRIP ALARM WILL GENERATE MANY
OTHER PRETRIP ALARMS. THEREFORE, IT SHOULD BE ADDRESSED FIRST.
CORRECTIVE ACTIONS:
1. Check PSCON and PSCON2
a. Inspect PSCON and PSCON2 contactor coils and wire connections. Verify there is no damage to
coils, and no damage, moisture, or corrosion in connections.
b. Check contactor coil resistance. Refer to Section 2.11 for resistance values.
2. Check PSCON and PSCON2 Amp Draw
a. Check PSCON and PSCON2 contactor coils amp draw. Use Component Test Mode (Section
5.2.4) to test. Refer to Section 2.11 for amp values. View current draw in Component Test Mode
screen.
b. Listen for PSCON or PSCON2 to pull in.
WARNING
!
Caution and good electrical practices must be used when working around and with high
voltage circuits.
If PSCON or PSCON2 contactor pulls in, PSCON / PSCON2 are OK. If PSCON or PSCON2 contac-
tor does not pull in, check for 12 VDC across the coil. If 12 VDC across A−1 & A−2, check wiring from
A−1 to B−1, if wiring is OK, replace contactor. No voltage - check F9.
3. Check PSCON, and PSCON2 Wiring
Inspect harness & control box connector pins & terminals. (See wiring schematic Section 10.3) Ver-
ify there is no physical damage to harness, and no damage, moisture, or corrosion in connectors.
