P.AH (pH Alarm High Limit)
Sets the high alarm point for the pH channel. When the measured pH value is greater than this
limit, the audible alarm will be activated and the pH feed output will be disabled. The alarm will
be cleared and feed will resume automatically when the measured pH value returns to within the
non-alarm range.
8.0: Use the UP and DOWN buttons to select a value between 6.0 and 9.0 pH. The value
must be greater than the pH alarm low value. The default value is 8.0 pH.
O.PF (ORP Proportional Feed)
Selects either fixed setpoint or proportional control.
Off: The ORP feed output is activated based on a simple above or below setpoint decision.
When the measured ORP value is less than or equal to the ORP setpoint, the ORP output feed
is turned on. Otherwise, the ORP feed output is turned off.
On: The ORP feed output is activated based on the difference between the ORP setpoint and
the measured ORP value. As the difference increases, the duration the ORP feed output is
turned on increases to 20, 30, 40, and 50 seconds of the 60 second cycle, and then the ORP
feed output is turned on continuously. This is the default setting.
O.OF (ORP Overfeed Timer)
When Off is selected, the ORP feed output will remain activated as long as an ORP feed condition
is indicated. When any other selection is made, an overfeed limit timer is enabled on the ORP feed
output. After the ORP feed output has been turned on for a period of time greater than this limit,
the ORP channel is turned off and placed into an overfeed alarm condition which must be manually
reset.
If ORP Proportional Feed: On has been selected, the ORP feed output must be on continuously for
the overfeed time limit, rather than in the part of the proportional feed cycle in which the ORP feed
output is on for only a portion of the 60 second proportional feed cycle.
After the ORP feed channel is placed into the overfeed alarm condition, the ORP channel is turned
off and the ORP Feed Mode indicator flashes rapidly to indicate the alarm. Press the ORP Feed
Mode button to return the ORP channel to the off, manual or automatic feed mode. This will reset
the ORP overfeed alarm and restart the overfeed timer. The ORP overfeed alarm will also be reset if
the controller is powered off and then back on.
The ORP overfeed timer is disabled when the ORP Feed Mode button is used to place the ORP
channel in the manual feed state.
Off: The ORP feed output will remain on for an unlimited amount of time.
