9.2
The pH FUN does not display the correct pH value
Cause
Remedy
The displayed pH value
on the pH FUN deviates
greatly from the check
measurement using
colour strips or Phenol
Red tablets.
•
The check measurement may
possibly be incorrect.
•
A new pH7 calibration of the pH
FUN may possibly be necessary
or even a replacement of the pH
electrode under certain
circumstances.
•
The pH measurement of the pH
FUN may be skewed due to an
external voltage on the pool water.
•
Repeat the check measurement following the
associated instructions precisely. If ne cessary, use a
different method for the check measurement. We
recommend the use of Phenol Red tablets.
•
Perform a pH7 calibration and observe the sequence
described in Chapter 6 precisely.
•
Check the earthing of the measuremen t water circuit.
You will achieve optimum results through two -sided
earthing both in the measurement water feed as well
as in the measurement water return.
9.3
The pH value in the pool is not correct
If the displayed pH value on the pH FUN deviates greatly from the check measurement using colour strips or Phenol
Red tables, please follow the instructions in Chapter 9.2.
Cause
Remedy
The pH value in the
pool lies above the
setpoint
The pH FUN requires more time to
adapt the pH value of the pool water
to the set setpoint.
Observe whether the pH value gets closer to the
setpoint. If it does not get sufficiently close, the pH FUN
triggers a dosing alarm.
In this case, please observe the appropriate instructions
in Chapter 9.1.
The pH value in the
pool overshoots the set
setpoint
An overdosing of pH-Minus has
occurred. The dosing rate of the pH
FUN is too high for the pool,
particularly in the area of the setpoint.
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
and thus prevent an overdosing.
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.
9.4
The dosing pump is not running
Cause
Remedy
The pH FUN shows a
dosing rate of 0% in the
normal view and the
dosing pump is not
running.
The pH value of the pool water has
the reached the setpoint (or lies
below the setpoint).
In this case, no additional pH -Minus dosing is required.
This is thus correct and the dosing pump does not run.
The pH FUN shows a
dosing rate of 0% in the
normal view and the
dosing pump is not
running. But the
displayed pH value lies
above the setpoint.
The dosing of the pH FUN is
blocked. The following causes are
possible for this:
•
No flow
•
Power-on delay
•
Level alarm
•
Dosing alarm
Switch to the alarm view of the pH FUN to determine the
cause of the blocking.
Please observe the information about the different
alarms in Chapter 9.1 to remedy the blocking.
The pH FUN shows a
dosing rate of 0% in the
normal view
but the dosing pump is
not running.
It is normal that the dosing pump is
switched on and off in intervals.
Depending on the current dosing
rate, it may only run for several
seconds per minute under certain
conditions. (see also Chapter 7.1)
If the dosing pump does not run at all
over multiple minutes, the fuse for the
pump may possibly be defective.
Replace the fuse for the dosing pump and contact
BAYROL service if necessary.
