Operating instructions
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 chapter 11.1.1 „Venting the dosing
pump“ on page 40).

11.2 Operating modes
The MEMDOS SMART LK dosing pump offers the following operating
modes:
Manual operation
- Manual setting of the delivery capacity,
Pulse input
- Controlling the stroke frequency and number of
strokes in dependence on the number of pulses and the pulse
spacing,
11.2.1 Manual mode
CAUTION
Danger of automatic start up!
If the dosing pump is in manual mode with a specifi ed stroke
frequency, 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.
