CHAPTER 5: SETTINGS<br />
5.9.4 RTD 11<br />
RTDs 7 through 10 default to “Bearing” RTD type. There are individual alarm and trip<br />
configurations for each RTD. This allows one of the RTDs to be turned off if it malfunctions.<br />
The alarm level, high alarm level and the trip level are normally set slightly above the<br />
normal running temperature, but below the bearing temperature rating. Trip voting has<br />
been added for extra reliability in the event of RTD malfunction. If enabled, a second RTD<br />
must also exceed the trip temperature of the RTD being checked before a trip will be<br />
issued. If the RTD is chosen to vote with itself, the voting feature is disabled. Each RTD<br />
name may be changed if desired.<br />

RTD 11 defaults to “Other” RTD type. The Other selection allows the RTD to be used to<br />
monitor any temperature that might be required, either for a process or additional<br />
bearings or other. There are individual alarm, high alarm and trip configurations for this<br />
