input/output status. When pressed for more than ten seconds, a
ten second phase-reversal simulation is carried out.
[Cut-out] B2 (fig. 4)
This button is used to set the pressure limit for stopping the
pump. It is enabled with a DIP switch. See section
5.1 Settings
via DIP switches
.
It is also used when setting the controller. See
5.2 Settings via
display
.
[Cut-in] B3 (fig. 4)
This button is used to set the pressure limit for starting the pump.
It is enabled with a DIP switch. See section
5.1 Settings via DIP
switches
.
It is also used when setting the controller. See
5.2 Settings via
display
.
[Print] B4 (fig. 4)
If the controller is equipped with an optional printer, this button is
used to print a resume of events of the last 15 days and pressure
data of the last seven days.
