Motor details screen
Figure 47: Motor details screen
This screen displays information pertinent to the Motor Monitoring feature. The feature consists
of motor winding temperature, motor bearing temperature, motor bearing vibration and motor
cooling coil leak detection. Setpoints on this screen allow any combination of these items to be
enabled or disabled based on the equipment applied. The motor could be equipped with different
types of sensors for this monitoring. Either RTD's or Transmitters could be applied for winding and
bearing temperature monitoring. Motor cooling coil leak detection could be done with either an
optical or float sensor. Setpoints on this screen allow for the enabling of the actual sensor type
applied.
Vibration baseline data can be entered manually or by running an auto baseline routine that plots a
baseline over a 1 hour period while the chiller is running.
This screen also serves as a gateway to a subscreen that allows programming of the winding
High Temperature Warning/Safety Shutdown thresholds and bearing High Temperature and High
Vibration Warning/Safety Shutdowns. Also, individual winding temperature sensors can be disabled
on this screen.
