Enables the type of temperature sensing device being used to sense
motor winding temperature. When set to any setting other than Disabled,
the respective temperatures are enabled and displayed. The HIGH
WINDING TEMPERATURE fault and warning occur when the programmed
thresholds for those conditions are reached. The settings are:
• Disabled: Disables the Winding Temperature feature. No winding
temperatures are displayed and the heading, text and data boxes
do not appear. The High Winding Temperature Fault and Warning
will not occur. This setting is used when the motor is not equipped
with winding temperature sensors or if is desired to disable the
feature for service reasons. This is the default setting. The winding
JCI Service
displays can be individually disabled using the Temperature Disable
Setpoint (Admin access level) on the Motor Setpoints screen.
• RTD: Enables and displays the 6 (2 per phase) motor winding
temperatures, as reported by the winding RTDs, by the motor
monitoring board serial communications.
Transmitter: Enables and displays the 3 motor winding
•
temperatures, as reported by the winding transmitters by the motor
monitoring board serial communications.
• VSD transmitter: Enables and displays the 3 motor winding

the respective temperatures are enabled and displayed. The HIGH
BEARING TEMPERATURE fault and warning occur when the programmed
thresholds for those conditions are reached. The settings are:
• Disabled: Disables the Bearing Temperature feature. No bearing
temperatures are displayed and the heading, text and data boxes
do not appear. The High Bearing Temperature Fault and Warning
JCI Service
will not occur. This setting is when if the motor is not equipped with

for service reasons. This is the default setting.
• RTD: Enables and displays the 2 motor bearing temperatures, as
reported by the bearing RTDs, via the motor monitoring board
serial communications.
• VSD transmitter: Enables and displays the 2 motor bearing
temperatures, as reported by the bearing transmitters via the VSD
logic board serial communications.
