#11
469 MOTOR MANAGEMENT RELAY – INSTRUCTION MANUAL
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.
