Possible problems and their remedy
9.1
The pH FUN reports an alarm
In the event of an alarm, the display of the pH FUN starts to blink and a signal tone is emitted in short intervals
(provided the acoustic alarm is activated). Acknowledge the alarm by pressing any key. The blinking of the display and
the signal tone are then ended.
Cause
Remedy
The pH FUN reports
"No flow"
The pool circulation is not running.
In this case, the "No flow" display is normal.
It disappears as soon as the pool circulation is switched
on again.
The pH FUN reports
"No flow" despite
running pool
circulation
The measurement water circuit or the
float of the flow sensor in the
measurement cell is blocked.
Check the measurement water circuit and the float and
remedy the blockage if necessary.
The pH FUN reports
"Upper alarm"
(for dosing of pH-Minus)
The measured pH value of the pool
water is too high.
After a new or partial filing, the pH value of the pool water
can lie above the upper alarm limit. The pH FUN
automatically lowers the pH value in this case by addition
of pH-Minus and in this way approaches the setpoint.
The pH FUN reports
"Lower alarm"
(for dosing of pH-Minus)
The measured pH value of the pool
water is too low.
An overdosing of pH-Minus may
possibly have occurred.
Reduce the value of the "Min.dos.rate" parameter (see
4.3.3 Setting options in the menu) in 3% steps to reduce
the dosing rate to the proximity of the setpoint.
Additionally, you can change the "Dose amount"
parameter from "normal" to "low" or from "high" to
"normal" in order to generally decrease the dose amount.
The pH FUN reports
"Upper alarm"
(for dosing of pH-Plus)
The measured pH value of the pool
water is too high.
An overdosing of pH-Plus may
possibly have occurred.
Reduce the value of the "Min.dos.rate" parameter (see
4.3.3 Setting options in the menu) in 3% steps to reduce
the dosing rate to the proximity of the setpoint.
Additionally, you can change the "Dose amount"
parameter from "normal" to "low" or from "high" to
"normal" in order to generally decrease the dose amount.
The pH FUN reports
"Lower alarm"
(for dosing of pH-Plus)
The measured pH value of the pool
water is too low.
After a new or partial filing, the pH value of the pool water
can lie below the lower alarm limit. The pH FUN
automatically approaches the pH value to the setpoint by
the addition of pH-Plus.
The pH FUN reports
"Level alarm"
The pH-Minus (or pH-Plus) canister is
empty.
Replace the empty canister with a new one.
The pH FUN reports
"Dosing alarm"
The pH FUN does not achieve the
desired pH setpoint in the water
despite the dosing of pH-Minus (or
pH-Plus).
Acknowledge the dosing alarm by pressing any button.
The pH FUN resumes with the dosing and thus adjusts
the pH value in the water to the setpoint again.
The pH FUN continues
to report a "Dosing
alarm"
Despite the dosing of pH-Minus (or
pH-Plus), the pH FUN is again not
able to bring the pH value of the pool
water close to the desired setpoint.
The dosing rate may possibly not be sufficient enough
to achieve sufficient proximity to the setpoint. In this
case, increase the dosing rate as follows:
•
Increase the value of the "Min.dos.rate"
parameter (see 4.3.3 Setting options in the menu) in 3%
steps to increase the dosing rate specifically near the
proximity of the setpoint.
•
Change the "Dose amount" parameter from
"normal" to "high" or from "low" to "normal" in order to
generally increase the dose amount.
You can also increase the dosing alarm response time.
To do this, double the set value of the "Dosing alarm"
parameter, e.g. from 60 min to 120 min.
