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 temper-
ature. 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.
