The optional Motor Monitoring feature allows moni-
toring of the compressor motor windings temperatures,
bearing temperatures, bearing vibration and motor
cooling coil leak detection. Any combination of wind-
ing, bearing and leak monitoring can be selected based
on the requirements of the job. Therefore, not all sen-
sors may be present in all applications. Setpoints on
the MOTOR DETAILS Screen allow any combination
of these items to be enabled or disabled based on the
actual equipment applied.

The motor could be equipped with different types of
sensors for this monitoring. Either RTD's or thermistors
could be applied for winding and bearing temperature
monitoring. Motor cooling coil leak detection could be
performed with either an optical sensor or float sensor.
Setpoints on the MOTOR DETAILS Screen allow for
the selection of the actual sensor type applied.
The hardware involved in this feature consists of motor
temperature sensors, vibration sensors, a cooling coil
leak detection sensor and a Motor Monitoring Board
(See Figure 98 on page 257).
