Dosing performance
The Dosing performance menu serves for adjusting (reducing) the dosing
performance.
The dosing volume to be provided must be determined by means of the
commonly used calculation methods. The dosing performance must be set
according to the determined dosing volume under consideration of personal
experience.
The picture shows the standard value with installed dosing pumps.
If external (less efficient) dosing devices are activated, it may be necessary to
deactivate the mutual locking.
The locking may only be deactivated if the dosing points lead directly into the
basin piping!
The picture below shows the Dosing performance menu when the control type 2-
point or time control was selected for the disinfectant dosing.
In this case, it is only possible to adjust the dosing performance of the pH
regulation pump. The disinfection volume is exclusively controlled via the
Disinfection settings menu. The connected dosing device may provide a setting
option for this.
Cycle time
The shortest cycle time is 30 seconds; i.e., every 30 seconds the dosing is activated for a varying length of time, depending on the
deviation from the set point.
It is divided into a maximum of 8 seconds dosing time for the pH regulation, followed by a pause of 3.5 seconds and then a
maximum dosing time of 15 seconds for the disinfection dosing, followed again by a pause of 3.5 seconds.
An extension of the cycle time extends the second pause time, thus reducing the maximum available dosing performance.
Example 1
Example 2
Example 1 shows the cycle time with 30
seconds = maximum dosing performance.
At standard SR10
-
pH regulation approx. 0.7 l/h
-
Disinfection approx. 1.2 l/h
Example 2 shows a cycle time of 60 seconds.
The extension of the pause time reduces the maximum available dosing
performance to 50%.
At standard SR10
-
pH regulation approx. 0.35 l/h
-
Disinfection approx. 0.6l/h
The IQntrol DOS MODBUS device series is delivered with a maximum dosing performance. Please determine the maximum available
dosing performance by means of the commonly used calculation methods in accordance with the applicable national standards.
(e.g., DIN HB = 2 g/m³ or FB = 10 g/m³ filtrate). Reduce the maximum dosing performance according to the determined values.
Due to the lower frequency, these stipulated dosing volumes are usually not needed in the private sector.
ATTENTION!
If the dosing performance is not reduced in the event of low requirements (indoor pool, low basin content), this can
lead to undesirable overdosing in case of unfavourable basin flow.
