9.10.7 Calibrating the sensor after the sensor has
been replaced
Once a sensor has been replaced, the new sensor
must be calibrated to the ambient pressure.
Prepare the pump for the calibration:
1. Before screwing in the sensor, check that no
dosing liquid is left in the place where the
pressure sensor will be screwed in!
2. Screw in the new sensor with the correctly fitting
O-ring.
3. Screw the sensor plug into socket 2.
4. Unscrew the suction valve.
Note
If the cable is broken, the dosing
controller and pressure
control/pressure display functions are
not active. When the "Menu/Info"
button is pressed twice to display the
chamber pressure, only "— — —" is
displayed.
Note
If the sensor fault cannot be corrected
immediately and if the pump is to
continue to run without a sensor,
switch off the dosing controller
(flow:OFF) and pressure control
function (P:OFF).
