4.4.1. Guardian calibration procedure
For calibration of Guardian you should perform the following steps:
1. Remove the M5 plug and connect an external pressure gauge to port described as
“Set point O/P”.
2. Turn the set point adjustment screw counter-clockwise until it turns freely.
3. Plug all other open ports (except reset) and turn the air supply on.
4. Adjust the set point adjustment screw clockwise until the pressure gauge indicates 0.5
bar below the required set point (i.e. 3.0 bar switching = 2.5 bar set).
5. Turn off the air supply.
6. Remove the pressure gauge, and re-install the M5 plug.
7. The calibration is now complete and the system is ready for use.
4.5. Ball lifters – TL…
This option is a great way to empty the pump of liquid if
there is no possibility of pump disconnection from the
installation. With this easy solution you can simply raise
the ball from the valve seat and allow the liquid to flow out
of the pump.
