4.9.4 RTD 11
RTD 11 defaults to Other RTD type. The Other selection allows the RTD to be used to monitor any temperature that might
be required, either for a process or additional bearings or other. There are individual alarm and trip configurations for this
RTD. Trip voting has been added for extra reliability in the event of RTD malfunction. If enabled, a second RTD must also
exceed the trip temperature of the RTD being checked before a trip will be issued. If the RTD is chosen to vote with itself,
the voting feature is disabled. The RTD name may be changed if desired.
