11.1.3 Calibrating the dosing pump
In dependence on the dosing medium you are using and the existing
delivery pressure, you must match the theoretical delivery capacity with
that which is actually measured. You use the
Calibration
function to
do this.
Precondition for action:
The plant sections on the discharge side of the dosing pump have
been installed correctly and are ready for operation.
Perform the following working steps:
1.
Fill the metering container with the dosing medium.
2.
Hold the end of the dosing pump's suction line in the metering
container.
3.
Vent the dosing pump, (see „Venting the dosing pump“ on page 40).
4.
Press

.
5.
Use the
or
key to choose the
Calibration
menu item and
press
OK
.
The dosing pump displays menu 5
Calibration.

6.
Use the
+
and
-
keys to set the percentage value of the delivery
capacity with which you want to carry out calibration. Setting range
10 % - 100 %.
7.
Press
Start
.
The dosing pump starts delivery and displays the number of
executed strokes.
8.
Press
Finish
as soon as you have achieved a measurable value
in the metering container.
The dosing pump stops and displays the theoretical value of the
delivery rate in ml.

9.
Read off the actual delivery rate from the metering container and
use the
+
and
-
keys to correct the displayed delivery capacity.
Adjustment range: -50 % - +50 %.
10.
Press
OK
.
The dosing pump is calibrated.

matically calculates the resulting delivery capacity and displays it.
2.
Use the
+
and
-
keys to set the desired stroke freqency.
Dosing pump has started.

CAUTION
Danger of automatic start up!
If the dosing pump is in manual mode with a specified stroke fre-
quency, it retains the stroke frequency even after you disconnect if
from the mains and then reconnect it. This means that dosing
medium can escape. Depending on the type and hazardousness of
the dosing medium, this can result in injury.
Stop the dosing pump before disconnecting it from the mains
supply.
Ensure that the dosing pump has been installed correctly before
connecting it to the mains supply.
