SECTION 2 - OPTIVIEW OPERATION
Pressure
This display indicates the pressure in the purge tank.
Exhaust Count
Exhaust count is only displayed after an initial 60-min-
ute bypass occurs at chiller start-up. Displays the num-
ber of purge exhausts that have occurred within the last
0 to 60 minutes, as displayed in the exhaust window.
When the purge unit reaches the excess purge threshold
or the chiller shuts down, the count display is frozen.
The count will be reset when the chiller starts again.
Exhaust Window
Displayed as 0 to 60 minutes. After a 60 minute by-
pass at chiller start, the exhaust window times from 0
to 60 minutes. During this period, purge exhausts are
counted and the exhaust count displayed is that which
has occurred in the last number of minutes displayed in
the exhaust window. After the exhaust window reaches
60, the purge exhausts that occurred in the oldest min-
ute are discarded from the exhaust count and exhausts
from the most recent minute are shifted in, providing a
rolling count of purge exhausts that occurred in the last
60 minutes. The count remains at 60 until the chiller is
restarted, whereupon the count is reset to 0.
