Troubleshooting Guide
Overview
The PIC has many features to aid the operator and the technician in troubleshooting a
17/19EX machine.
•
By using the LID display, the chiller actual operating conditions can be viewed while
the unit is running.
•
The Control Algorithm Status screens will display various screens of information in
order to diagnose problems with chilled water temperature control, chilled water tem-
perature control overrides, hot gas bypass, surge algorithm status, and time schedule
operation.
•
The Control Test feature allows proper operation and testing of temperature sensors,
pressure transducers, the guide vane actuator, oil pump, water pumps, tower control,
and other on/off outputs while the compressor is stopped. It also has the ability to lock
off the compressor and turn on water pumps for pumpout operation. The display will
show the required temperatures and pressures during these operations.
•
Other Service menu tables can access configured items, such as chilled water resets,
override set points, etc.
•
If an operating fault is detected, an alarm message is generated and displayed on the
LID default screen. A more detailed message — along with a diagnostic message —
also is stored into the Alarm History table.
