5.9.4 RTD 11
PATH: SETPOINTS ZV S8 RTD TEMPERATURE ZV 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.
