12. Calibration of the stroke frequency adjustment
The maximum performance of the pump was calibrated by the manufacturer under standard conditions.
In operation the performance may differ according to the surroundings and the medium. The operator may
therefore adapt the performance of the pump to the actual flow rate.
12.1 Calibration procedure
1. After installation and start-up of the pump, take the suction line out of the dosing container and put it
into a priming aid containing the same medium.
2. In order to ventilate the dosing pump and the line, operate the dosing pump until no bubbles are left in
the lines. Then switch off the dosing pump.
3. Fill up the priming aid again and mark the fluid level.
4. Turn the stroke frequency dial to the right (< 0%).
5. Adjust the required flow rate as follows:
5.1 Switch on the dosing pump and after 1 s turn the dial within 5 s right to the left (> 100%).
5.2 Within 5 s turn it to the right (< 0%).
5.3 Within 5 s adjust it to the required flow rate (Target %).
(If one of the steps takes longer than 5 s, no calibration takes place and the dosing pump starts). The
required flow rate can be calculated via the maximum performance of the dosing pump. Example:
15 l/h = max. performance of the dosing pump, 9 l/h = required performace--> 9/15 = 60%.
6. The dosing pump will start operating for 60 s and will then stop automatically. Then switch off the dos-
ing pump.
7. Fill up the quantity that was conveyed from the priming aid with a measuring glass to the marked fluid
level.
8. The quantity in ml or cm³ filled up from the measuring glass corresponds with the dosing quantity. The
actual flow rate of the maximum performance in % can now be calculated. This means: actual flow rate
[%] = quantity taken out * 6 / max. performance of the dosing pump.
(Example: 15 l/h = max. performance of the dosing pump, 180 ml = quantity taken out in 60 s -->
actual flow rate = 180 * 6 / 15 = 72 %)
7. Put the suction line back into the container.
8. Turn the stroke frequency dial to the right (< 0%).
9. Switch on the dosing pump and after 1 s turn the dial within 5 s right to the left (> 100%).
10. Within 5 s turn it to the right (< 0%).
11. Adjust it within 5 s to the calculated, actual flow rate (ACTUAL %).
12. The pump will calibrate automatically to the new value.
12.2 Deleting the calibration
-
Turn the stroke frequency dial to the right (< 0%) while the dosing pump is switched off.
-
Switch on, after 1 second turn the stroke frequency dial within 5 s to the left (> 100%). Within 5 s turn
it to the right (< 0%) and then turn it to the left (> 100%).
After switching on/off the dosing pump once, it is back in delivery status.
