DESCRIPTION
Motor Run (LED)
Illuminates when the OptiView control center is commanding the motor to run.
Motor % Full Load Amps
Displays the input current as a percentage of chiller full load amps.
VSD Output Frequency
Displays the frequency at which the VSD is operating the motor. This value is
returned from the VSD Logic Board.
VGD Position
Displays the present variable geometry diffuser position as a value between 0%
(closed) and 100% (full open).
Motor Temperatures
Displays the enabled motor winding temperatures for phase A, B and C. Individ-
ual temperatures can be disabled 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 individual temperature is disabled, the temperature data
box does not appear. Any input that registers as open will display the minimum
temperature.
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
disabled is not used in the calculation. A maximum of 6 temperatures is used to
calculate the average.
Motor Housing Temperature
Displays the temperature of the motor housing sensed at the thermistor on the
motor externally.
Motor Housing Temperature Setpoint
Displays the target temperature for the motor cooling control. It is equal to enter-
ing condenser water temperature plus the programmable setpoint offset.
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
