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. P.OF (pH Overfeed Timer) When Off is selected, the pH feed output will remain activated as long as a pH feed condition is indicated. When any other selection is made, an overfeed limit timer is enabled on the pH feed output. After the pH feed output has been turned on for a period of time greater than this limit, the pH channel is turned off and placed into an overfeed alarm condition which must be manually reset. If pH Proportional Feed: On has been selected, the pH feed output must be on continuously for the overfeed time limit, rather than in the part of the proportional feed cycle in which the pH feed output is on for only a portion of the 60 second proportional feed cycle. After the pH feed channel is placed into the overfeed alarm condition, the pH channel is turned off and the pH Feed Mode indicator flashes rapidly to indicate the alarm. Press the pH Feed Mode button to return the pH channel to the off, manual or automatic feed mode. This will reset the pH overfeed alarm and restart the overfeed timer. The pH overfeed alarm will also be reset if the controller is powered off and then back on. The pH overfeed timer is disabled when the pH Feed Mode button is used to place the pH channel in the manual feed state. OFF: Off - the pH feed output will remain on for an unlimited amount of time. 15: 15 Minutes. 30: 30 Minutes. 60: 60 Minutes (1 Hour). 120: 120 Minutes (2 Hours). 180: 180 Minutes (3 Hours). 240: 240 Minutes (4 Hours) - default P.AL (pH Low Alarm Limit) Sets the low alarm point for the pH channel. When the measured pH value is less 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 nonalarm range. 7.0: Use the UP and DOWN buttons to select a value between 6.0 and 9.0 pH. The value must be less than the pH alarm high value. The default value is 7.0 pH. dEo (Demonstration Mode) Places the controller in Demo Mode for showroom display, presentations, etc. bPr (Audible Alarm) The Beeper setting allows the audible alarm to be enabled (default) or disabled.
