Adjusting The Dosing Controllers - Grundfos Oxiperm OCD-164 Montage- Und Betriebsanleitung

Dosing pumps for the systems OCD-164-220 to
OCD-164-2000
1. Calibration is made using calibration cylinders.
2. Fill both calibration cylinders with water up to a certain mark.
3. Place the suction lines into the calibration cylinders.
4. Use a stopwatch to determine the time required to dose a
particular quantity of liquid.
5. Remove the suction lines from the calibration cylinders, read
off the new value, and calculate the dosing performance.
6. If the calibrated dosing volume deviates from the setpoint
(table), the dosing rate is corrected with the stroke adjustment
button (on the dosing pump) and checked once again.
Consumption of components, see table in section
2.1.1 Performance and consumption
7. If a pump deviation occurs, use the stroke adjustment button
to re-adjust it and re-calibrate it.
If several calibration attempts are made, ensure that the suction
lines do not become filled with air. If necessary, deaerate the
pump again.

Pos. Description
1 Clamping nut
2 Adjusting screw
3 Sensor
The dosing controllers are correctly set, if the LEDs on the
controller flowchart flash regularly, see section
display elements, items 1 and 4.
If the LEDs are off, the dosing controllers are set too high. If the
LEDs flash very rapidly (or light up permanently), the dosing
controllers are set too low.
Adjustment
1. Loosen the clamping nut (1).
2. Readjust the sensor using the adjusting screw (2).
3. If the LED is off, the sensor is set too high.
4. Adjust the sensor from above to the correct working point,
until the LED flashes regularly.
5. Adjust the sensor about approx. 1 mm lower with the
adjustment screw (2).
6. Fix the sensor using the clamping nut (1).
