Start-up and Shutdown
•
Pumpout Chiller Off—7 Days. Indicates the
percentage of the total purge pump-out time during the
past seven days that occurred when the chiller was not
operating. You can use it to help determine if a leak is
present on the high side or the low side of the chiller.
•
Pumpout—Life. Indicates the total purge pump-out
time that has accumulated over the life of the purge.
•
Purge Rfgt Cprsr Suction Temp. Indicates the purge
refrigerant compressor suction temperature. It is useful
for diagnosing purge system problems.
•
Purge Liquid Temp. Indicates the temperature sensed
by the controller and used to inhibit purge operation.
102
The purge liquid temperature sensor, when the chiller is
operating, is the chiller saturated condenser
temperature sensor; when the chiller is Off, it is the
chiller saturated evaporator temperature sensor. If this
temperature is below the Pumpout Inhibit Temperature
that is defined in the Settings menu, pump-out is not
allowed. This value is used to prevent inefficient
operation of the purge under certain conditions.
•
Carbon Tank Temp. Indicates the carbon bed
temperature and is useful for monitoring regeneration
and for diagnosing regeneration system problems.
