RTD Location Settings
The monitor allows you to define the location of each monitored RTD
independently using the RTD Location settings.
Define the RTD Location settings using the following suggestions:
If an RTD is not connected to an input or has failed in place and will
not be replaced, set RTD Location for that input equal to NONE.
For RTDs embedded in motor stator windings, set RTD Location
equal to WDG.
For inputs connected to RTDs measuring bearing race temperature,
set RTD Location equal to BRG.
For the input connected to an RTD measuring ambient motor cooling
air temperature, set RTD Location equal to AMB. Only one ambient
temperature RTD is allowed.
For inputs connected to monitor temperatures of other apparatus, set
RTD Location equal to OTH.
If OTH is selected for the RTD Location, the SEL-701-1 Monitor allows you to
enter a 10-character description for the RTD. This description will be used when the
