4.5. " OFA " over - feed protection
Your pH Perfect is equipped with protection to prevent over-feeding with
corrective solution in the event of a problem on 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 240 minutes. Figure
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 (240 minutes in the original setting). The appliance
is then safe.
• To cancel this protection and start your pH Perfect, press the "CAL/Enter"
button (possible on the 2 steps of the OFA alarm).
Note: Make sure that the pH sensor is in good condition. If necessary, clean
and/or recalibrate it.
• The over-feed protection is set by default for a maximum time of 240 minutes.
It is possible to adjust it from "OFF" (disabled) to "240" by intervals of
1 minute.
A fairly high setting is strongly recommended to avoid any inopportune
Note:
and/or unjustified start.
• To regulate the OFA when in the "Settings" menu, enable the option list by
pressing the "CAL/Enter" button (the value in minutes flashes). Then select
the value chosen using the "up" and "down" navigation buttons.
The adjustment is made by intervals of 1 minute.
Accept the choice by pressing the "CAL/Enter" button.
Special functions of the OFA
To prevent "false" alarms just after installing a pH Perfect (if the pH is poorly
balanced), the OFA may be temporarily disabled for 24 or 48 hours:
> Press "up" & "down" & "CAL": OFA disabled for 24 hours (automatically
re-enabled).
> Press "up" & "down" & "SET": OFA disabled for 48 hours (automatically
re-enabled).
