Log 4 - Pumpout time first 3 hours after last chiller shutdown (Hrs & Min.)
Indicates pumpout activity during the first three hour period after the last chiller shutdown.
Sometimes not all of the air that has leaked into the ch iller can be completely purged while the
chiller is operating. The only way to purge this air is to operate the purge while the chiller is
off. This is an automatic function of the purge when operating in the “ADAPTIVE” mode. Any
time the chiller stops, the purge automatically starts and runs for three hours. (The actual
period may be longer than three hours, because of the drain back equalization periods (see
page 44), but the purge time will be three hours). Typically this is sufficient time to remove
any residual air left over from the previous chiller run cycle. It is important to be able to
distinguish this purge activity from other purge activity resulting from air infiltration occurring
as a result of the chiller being off. This additional informatio n will aid the chiller operator in
diagnosing leaks.
NOTE: When in the “Adaptive" mode, anytime the chiller shuts down the purge automatically
starts and runs for 3 hours. When the purge is operating in the 3 -hour period following
chiller shutdown, it may go into several drain back equalization cycles. This is normal.
The purge is programmed to anticipate drainage imbalance conditions due to purge
tank pressure gradients that can develop when the chiller is not running (see Drain
Back Equalization Cycle on page 44 for further explanation). Even though there may
be drainage delays during this period, the total purge run time will be three hours.
Therefore, due to the drain back equalization cycle you may see purge activity longer
than 3 hours after a chiller shuts down.
Log 5 - Last 30-Day Chiller Run Time
(daily average)
(in hours)
Indicates daily average chiller run time based on last 30 -day sliding window.
Log 6 - Total Purge Condensing Unit Run Time (in hours)
Indicates total purge condensing unit run time from installation to date
(This historical log is
not re-settable).
Log 7 - Total Cumulative Pumpout Time
(in hours and minutes)
Indicates total purge pumpout time from installation to date
(This historical log is not re-
settable).
Log 8 - 30-Day Average Pumpout Time per day (Hrs & Min.)
Indicates average purge pumpout time per 24 hour period over last 30 -days
Log 9 - Number of Adaptive or Auto run cycles “Chiller ON”
(
maximum 8 cycles per day)
Indicates the number of current minimum “ON” purging cycles the purge will run per day
(while the chiller is running) in the “ADAPTIVE” or “AUTO” mode.
