RTD Location Settings
Table 4.23 RTD L ocation Settings
The relay 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.
