Once the input is set with an SPN and FMI, check the "Event Response Configuration". Not all SPN and FMI combinations are valid. Table 3 indicates which FMIs are valid for which SPNs. If a combination other than one indicated with a "Y" in the table above is configured, the event will not trigger any response by the OCP. The OCP may not give the option of an invalid FMI for a given SPN. In Cat ET, there is no restriction on the SPN/FMI combination. An invalid combination in Cat ET will result in an "Out of Range" error.
