4.6 "OFA" over-feed protection
F
To cancel this protection and start your pH Perfect, press the "CAL/Enter" button (possible on the
2 steps of the OFA alarm).
The default dosage on the pH Perfect is acid
(injection of pH minus) (E).
To change it when in the "Settings" menu, enable the option list by
pressing the "CAL/Enter" button
(a small arrow appears on the right of the screen and the type of
dosage flashes). Then select the dosage using the "p" and "q"
navigation buttons.
Accept the choice by pressing the "CAL/Enter" button.
Your pH Perfect is equipped with protection to prevent over-feeding
in the event there is a problem with the pH sensor, for example. The
purpose of this protection, called "OFA" (Over Feed Alarm), is to pause
the appliance if it has not reached the set point at the end of the time;
set by default at 4 hours (F).
The "OFA" over-feed protection functions in 2 steps:
#1: "OFA alarm" flashes on the LCD screen after 70% of the OFA
programmed time has been used without reaching the set point.
However, the appliance continues running.
#2: "Stop OFA" is displayed on the LCD screen after reaching 100%
of the OFA programmed time
(4 hours in the original setting). The appliance is then safe.
