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.
