Rtd S 7 To 10 - GE 469 Instruction Manual

5.9.3 RTDs 7 to 10
#7
5–72
MESSAGE
RTDs 1 through 6 default to "Stator" 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 is normally set slightly above the normal running temperature. The high
alarm is usually set as a warning of a trip or to initiate an orderly shutdown before tripping
occurs. The trip level is normally set at the insulation 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.
