Alarms and safety functions
The wide range of safety functions and alarm mechanisms of the pH FUN ensure that possible problems are reliably
detected and signalled early on.
8.1
The alarm view of the pH FUN
As soon as the pH FUN has detected a possible problem, it signals this in the following way:
•
The pH FUN automatically switches to the alarm view (see also 8.4), where possible problems and alarms are
displayed. The entire display blinks additionally.
•
Acoustic alarm, provided it is switched on in the menu (see 4.3.3 Setting options in the menu).
In the normal view, the pH FUN signals pending alarms by blinking of the current pH value display. Using the
buttons, you can switch back and forth between the normal view and the alarm view.
8.2
Acknowledging alarms
Press any key to acknowledge the displayed alarms. This will stop the blinking of the display and the acoustic alarm
(if activated).
8.3
Blocking dosing
For safety reasons, the pH FUN blocks the dosing of pH-Minus (or pH-Plus) for the following events:
•
Missing measurement water flow through the measurement cell
•
During the power-on delay
•
During a level alarm
•
During a dosing alarm
Only when the reason for the blocking is no longer present will the pH FUN again enable the dosing.
When dosing is blocked, the pH FUN always shows a dosing rate of 0% in the normal view.
8.4
Possible displays in the alarm view
The following displays can appear in the alarm view:
Display
Explanation
No alarms
There are no alarms pending and the flow signal is present.
No flow
No measurement water flow through the measurement cell (missing flow signal).
Delay Xmin
A power-on delay is running after the switching on of the pH FUN or after an interruption of the
measurement water flow. The pH FUN shows the remaining time of the power -on delay in
minutes.
Upper alarm
Upper threshold alarm. The current pH measured value lies above the upper alarm limit.
Lower alarm
Lower threshold alarm. The current pH measured value lies below the lower alarm limit.
Level alarm
The pH-Minus (or pH-Plus) canister is empty and must be replaced.
Dosing alarm
The pH FUN has detected a dosing alarm since sufficient approaching of the pH value to the
desired setpoint was reached.
Flow monitoring
A measurement and regulation of the pH value is only possible if the pool circulation is running and pool water is
continually flowing through the measurement water circuit. A flow sensor is installed in the measurement cell of the
pH FUN for this reason.
