Calibration
The MX…461…P magnetic valves are factory-calibrated at 0% and 100% stroke. When
commissioning the valves (especially under extreme usage conditions) there may still
be some leakage via control path A → AB with a 0% stroke control signal (0 Vdc, 4 mA
or 2 Vdc). In this case, the valve can be recalibrated as follows (see Figure 8):
• Use a pin or paper clip to push the button in opening (A) in the terminal housing.
• During calibration, the LED light (B) in the electronics module will flash green for
approximately 10 seconds. The valve will be briefly closed and fully opened.
Application Example
CAUTION:
This valve is suitable for straight-through normally closed or three-way
applications only and should only be installed in a mixing arrangement.
A Mixing circuit
B Mixing circuit with bypass (underfloor heating)
C Injection circuit
D Diverting circuit
E Injection circuit with straight-through valve
