2. Operating modes

The unit has the following operating modes:
Run mode (normal operating mode), display mode (indication of para-
meters and the set parameter values), programming mode (setting of
the parameter values).
Run mode:
When the supply voltage has been applied, the unit is in the Run
mode. It monitors and switches the transistor output according to the
set parameters. The value of the analog output depends on the
system pressure.
The LED display indicates the current system pressure, the red LED
indicates the switching state of the output.

Display mode:

When the "Mode/Enter" button is pressed for a short time, the unit
passes to the Display mode. Internally it remains in the operating
mode. Irrespective of this the set parameter values can be read:
• When the "Mode/Enter" button is pressed for a short time, the
parameters are scrolled.
• When the "Set" button is pressed for a short time, the correspon-
ding parameter value is displayed for approx. 5s; then the unit
returns to the Run mode.

Programming mode:

The unit passes to the programming mode when after the selection of
a parameter value (Display mode) the "Set" button is pressed until the
display of the parameter value is changed. Internally the unit remains
in the operating mode. It continues its monitoring function with the
existing parameters until the change has been terminated.
You can change the parameter value by pressing the "Set" button and
confirm it by pressing the "Mode/Enter" button. The unit returns to
the Run mode when no button has been pressed for 5s.
