Kohler 24RCL manual Faults, 2.6.1Warnings, 2.6.2Shutdowns, 2.6.3ATS Communication Errors

2.6 Faults

Selected fault conditions are shown in Figure 2-5. Fault conditions are classified as warnings or shutdowns. If a fault occurs that is not listed in the table, contact an authorized distributor/dealer for service.

Note: All ECM faults are grouped under one listing in Figure 2-5.

If a programmable interface module (PIM) is connected to the generator set controller, additional faults can be activated by customer-supplied equipment. See TT-1584, Installation Instructions for the Programmable Interface Module, for available inputs and outputs.

2.6.1Warnings

The controller displays a fault message but the generator set does not shut down on a warning. The controller resets automatically after a warning condition is corrected.

2.6.2Shutdowns

Under a fault shutdown condition, the generator set shuts down automatically and the controller displays a fault message. The OFF LED flashes. See Figure 2-5.

Shutdown switches (such as the low coolant level switch or high engine temperature switch) on the generator set will automatically reset when the problem is corrected. However, the fault condition at the controller does not clear until the controller is reset.

The generator set cannot be restarted until the fault condition is corrected and the controller is reset. See Section 2.6.4 to reset the controller after a fault shutdown.

2.6.3ATS Communication Errors

When a Model RXT transfer switch is used, an ATS fault indicates that the connection to the interface board on the transfer switch has been lost. Check the connection to the ATS interface board.

2.6.4Resetting the Controller after a Fault Shutdown

Always identify and correct the cause of a fault shutdown before resetting the controller. Check the fault message displayed on the controller and refer to Figure 2-5 to identify and correct the fault condition before proceeding. Contact an authorized distributor/dealer for service, if necessary.

Press the OFF button to reset the controller, or follow the procedure below. See Figure 2-4.
