4.9.3 RTDS 7 TO 10
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, high 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.
