Generator Set Control Panel for Switchgear Conversion Caterpillar

The control board provides one spare fault input (connector contact 12). Optional factory devices or a device that is provided by the customer can be connected to the spare fault input. The response of the control board to a spare fault is selectable. The fault may be either an alarm fault or a shutdown fault. For a spare fault that is a shutdown fault, the inclusion of the fault protection timer is selectable. When there is a battery negative signal ("B-") at the spare fault input, the control board responds in the preselected manner. The following options are available: alarm versus shutdown and "FPT" versus no "FPT". On the front panel, the spare fault indicator is amber for an alarm fault or red for a shutdown fault. For more information, see Systems Operation, "Fault Management".

Some of the optional factory devices that can be connected to the spare fault input are listed below.

• Engine Coolant Loss Sensor
