Kohler 20-3250 kW manual General Troubleshooting

Section 4 General Troubleshooting

This section contains generator set troubleshooting, diagnostic, and repair information.

Note: The controller clock must be set each time the engine battery(ies) are disconnected. The controller clock determines exercise run time and event records. See Menu 6—Time and Date, for setup.

Use the following charts to diagnose and correct common problems. First check for simple causes such as a dead engine starting battery or an open circuit breaker. The charts include a list of common problems, possible causes of the problem, recommended corrective actions, and references to detailed information or repair procedures.

Maintain a record of repairs and adjustments performed on the equipment. If the procedures in this manual do not explain how to correct the problem, contact an authorized distributor/dealer. Use the record to help describe the problem and repairs or adjustments made to the equipment.

Battle Switch/Fault Shutdown Override Switch. The battle switch function forces the system to ignore normal fault shutdowns such as low oil pressure and high engine temperature. The battle switch does not override the emergency stop and overspeed shutdown. When the battle switch function is enabled, the generator set continues to run regardless of shutdown signals where potential engine/alternator damage can occur.

When this input is enabled, the yellow warning lamp illuminates and stored warning/shutdown events that are ignored continue to log in Menu 5—Event History.

See Section 2.8.9, Menu 9—Input Setup, for information on how to enable the battle switch feature.

Cooldown Temperature Override Function. This function provides the ability to bypass the generator set cooldown temperature shutdown and force the unit to wait for the engine cooldown time delay.

See Section 2.8.8, Menu 8—Time Delays, for information on how to enable the cooldown temperature override feature.
