VALVE GP-RELIEF 1398475 - Caterpillar

Outputs
The discrete I/O module has eight "Form C" relay outputs. Each output can be configured to signal one of many possible events. Each output can be configured for either general events or for specific events. The Cat ET Service Tool (CST) is used in order to configure the discrete I/O module outputs.For general events, each output activates whenever any "Alarm Condition", "Shutdown Condition", or any combination of the two conditions exist.For specific events, each output activates whenever the diagnostic message contains the SPN and Failure Mode Identifier (FMI) combination that matches the SPN and FMI combination that is programmed for that particular output.The FMI defines the nature of the event, such as above range or below range. The FMI includes events such as high or low alarms, shutdowns, or condition exists.The output configuration parameters are shown in table 3.
