FIGURE 39 - MOTOR DETAILS SCREEN

OVERVIEW
This screen displays information pertinent to the Mo-
tor Monitoring feature. The feature consists of motor
winding temperature, motor bearing temperature, mo-
tor bearing vibration and motor cooling coil leak detec-
tion. 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 Tempera-
ture Warning/Safety Shutdown thresholds and bearing
High Temperature and High Vibration Warning/Safety
Shutdowns. Also, individual winding temperature sen-
sors can be disabled on this screen.
