Check GENCOIL Coil
engine
Description
Generator contactor circuit is shorted or open; engine operation shuts down with alarm, or electric operation alarms only.
Activation Conditions
Generator contactor (GENCON) circuit is shorted or open.
Unit Behavior
Engine Operation: Engine and unit shutdown and alarm. Electric Operation: Alarm only.
Reset Conditions
Auto Reset or alarm may be manually reset via keypad or by turning the unit off, then back on again.
Corrective Actions
1. Check GENCON a. Inspect contactor coil and connector. Verify there is no damage to coil, and no damage or corrosion to connector. b. Check contactor coil resistance. Refer to Section 2.11 for contactor coil resistance values. Cannot be opened (infinite ohms), shorted (Zero Ohms) or shorted to ground. 2. Check GENCON Using Component Test Mode a. Use Component Test mode to energize GENCON. (Refer to Section 5.2.4) Verify Current Draw on Component Test mode Screen. Refer to Section 2.11 for correct electrical values. b. Check coil voltage between A1 and A2. Verify 12 VDC between A1 and A2. c. Check resistance at contacts. Verify contacts are closed at L1-T1, L2-T2, L3-T3. 3. Check GENCON Wiring a. Inspect harness and control box connector pins and terminals. CCB-24 to GENCON-A1, GENCON-A2 to ground. (See wiring schematic Section 10.2.) Verify there is no physical damage to harness, and no damage, moisture, or corrosion in connectors. b. Check PSCON1 and PSCON2 for loose wires or open contact. Verify there is no physical damage to harness, and no damage, moisture, or corrosion in connectors.
