SI0224 - SOFTWARE ENHANCEMENTS (VER 22) EFFECTIVE APRIL 2010
GENERAL
Beginning April 2010, enhanced software will be sup-
plied in new production YK chillers and replacement
microboard kit (P/N 331-02430-601). This software
is backward compatible to all previous YK chillers
equipped with microboard (P/N 031-02430-000) or
(P/N 031-02430-001). The enhancements are listed be-
low.
The version and program card part number is
C.OPT.01.22.307 (P/N 031-02474-001).
MOTOR MONITORING
This software version supports the optional Motor
Monitoring feature. This feature allows monitoring of
the compressor motor windings temperatures, bearing
temperatures, bearing vibration and motor cooling coil
leak detection. Any combination of winding, bearing
and leak monitoring can be selected based on the re-
quirements of the job. Therefore, not all sensors may
be present in all applications. Setpoints allow any com-
bination 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 RTDs 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 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.
This board resides in an enclosure that is mounted sep-
arately from the OptiView Control Center. The motor
monitoring board communicates with the microboard
COM3 port via RS-485 Modbus serial communica-
tions. Whenever a monitored parameter exceeds a
warning or safety threshold, a warning is displayed
or a safety shutdown is performed as appropriate. The
messages and actions are detailed in
OptiView Control
Panel – Operation (Form 160.54-O1).
The motor monitoring feature must be enabled.
Once enabled, the MOTOR DETAILS and MOTOR
SETPOINTS screens are available, where all informa-
tion pertinent to the feature are displayed.
Refer to
OptiView Control Panel – Operation (Form
160.54-O1)
for display screens and messages. See
SECTION 32 - MOTOR MONITORING on page 257
for a complete explanation of this feature.
