PR 0.3 Effective 8/99
Setpoint P2L1 above. There are six specifically-labeled stator RTD inputs on the URTD module
whose readings can trigger this particular type of trip. See 9.1.8 for setting advice.
CAUTION
If WD T is set to OFF, the thermal-model protection reverts to the non-RTD algorithm even if a
URTD is connected.
5.2.3 Setpoint P2L3, Winding Temp Alarm (WD A) —
Specifies the motor stator winding
temperature limit above which any winding RTD will produce an alarm output from the relay.
This alarm can also be set to OFF. Alarm temperature values are in degrees C or F depending
on Setpoint P2L1 above. There are six specifically-labeled stator RTD inputs on the URTD
module whose readings can trigger this particular type of alarm.
5.2.4 Setpoint P2L4, Motor Bearing Trip (MB T) —
Specifies the motor bearing temperature
limit above which either of the two motor bearing RTDs will cause the relay to trip the motor.
This trip can also be set to OFF. Trip temperature values are in degrees C or F depending on
Setpoint P2L1 above. There are two specifically-labeled motor bearing RTD inputs on the URTD
module whose readings can trigger this particular type of trip.
5.2.5 Setpoint P2L5, Motor Bearing Alarm (MB A) —
Specifies the motor bearing temperature
limit above which either of the two motor bearing RTDs will produce an alarm output from the
relay. This alarm can also be set to OFF. Alarm temperature values are in degrees C or F
depending on Setpoint P2L1 above. There are two specifically-labeled motor bearing RTD
inputs on the URTD module whose readings can trigger this particular type of alarm.
5.2.6 Setpoint P2L6, Load Bearing Trip (LB T) —
Specifies the load bearing temperature limit
above which either of the two load bearing RTDs will cause the relay to trip the motor. This trip
can also be set to OFF. Trip temperature values are in degrees C or F depending on Setpoint
P2L1 above. There are two specifically-labeled load bearing RTD inputs on the URTD module
whose readings can trigger this particular type of trip.
5.2.7
Setpoint P2L7, Load Bearing Alarm (LB A) —
Specifies the load bearing temperature
limit above which either of the two load bearing RTDs will produce an alarm output from the
relay. This alarm can also be set to OFF. Alarm temperature values are in degrees C or F
depending on Setpoint P2L1 above. There are two specifically-labeled load bearing RTD inputs
on the URTD module whose readings can trigger this particular type of alarm.
5.2.8 Setpoint P2L8, Auxiliary RTD Temp Trip (AX T) —
Specifies the auxiliary RTD
temperature limit above which the relay will trip the motor. This trip can also be set to OFF. Trip
temperature values are in degrees C or F depending on Setpoint P2L1 above. There is one
specifically-labeled auxiliary RTD input on the URTD module whose readings can trigger this
particular type of trip.
5.2.9
Setpoint P2L9, Auxiliary RTD Temp Alarm (AX A) —
Specifies the auxiliary RTD
temperature limit above which the relay will produce an alarm output. This alarm can also be set
to OFF. Alarm temperature values are in degrees C or F depending on Setpoint P2L1 above.
