RTDs 7 through 10 default to Bearing RTD type. There are individual alarm and trip configurations for each RTD. This
allows one of the RTDs to be turned off if it malfunctions. The alarm level and the trip level are normally set slightly above
the normal running temperature, but below the bearing temperature rating. 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. Each RTD name may be
changed if desired.
