6.4 Deaerating the pump
1. Read section
6.1 Preparing the pump for startup
.
2. Open the deaeration valve by approximately half
a turn.
3. Press the [100%] key and hold it down until liquid
flows out of the deaeration hose continuously
and without any bubbles.
4. Close the deaeration valve.
6.5 Calibrating the pump
The pump is calibrated in the factory for media with a
viscosity similar to water at maximum pump
backpressure. See section
.
If the pump is operated with a backpressure that
deviates or if dosing a medium whose viscosity
deviates, the pump must be calibrated.
For pumps with FCM control variant, it is not
necessary to calibrate the pump if there is deviating
or fluctuating backpressure as long as the
"
AutoFlowAdapt
" function has been enabled. See
section
.
Requirements
•
The hydraulics and electrics of the pump are
connected. See section
•
The pump is integrated into the dosing process
under operating conditions.
•
The dosing head and inlet line are filled with
dosing medium.
•
The pump has been deaerated.
WARNING
Pressurised dosing medium
Death or serious personal injury
- Do not open the deaeration valve by
more than one full turn.
Press the [100%] key and simultaneously
turn the click wheel clockwise to increase
the duration of the process to up to 300
seconds. After setting the seconds, do not
press the key any longer.
During calibration the pump performs 100
strokes/minute as a standard. If the
SlowMode
function is activated, the
number of strokes/minute is 60 at 50 %
and 30 at 25 %.
