OVERVIEW
This screen displays information pertinent to the Motor
Temperature Monitoring feature. The feature consists
of motor winding temperature and motor housing tem-
perature. Also, individual winding temperature sensors
can be disabled on this screen.
DISPLAY ONLY
Motor Run (LED)
Illuminates when the OptiView™ control center is
commanding the motor to run.
%Input Full Load Amps

MOTOR DETAILS SCREEN
VGD Position
Displays the present variable geometry diffuser posi-
tion as a value between 0% (closed) and 100% (full
open).
Motor Temperatures
Displays the enabled motor winding temperatures for
phase A, B and C. Individual temperatures can be dis-
abled using the TEMPERATURE DISABLE Setpoint.
The software prevents more than 2 of the 3 sensors at
either end of the motor to be disabled. When an in-
dividual temperature is disabled, the temperature data
box does not appear. Any input that registers as open
will display the minimum temperature 32°F.
Average Winding Temperature
This value is calculated as the average of all enabled
and valid motor winding temperatures. Any winding
temperature that registers as open, out of range or dis-
abled is not used in the calculation. A maximum of 6
temperatures is used to calculate the average.
