ment and evaluation functions and provides output signals according
to the set parameters.

Display mode
Indication of parameters and the set parameter values
When the "Mode/Enter" button is pressed briefly, the unit passes to
the Display mode which allows parameter values to be read. The inter-
nal sensing, processing and output functions of the unit continue as if
in Run mode.
• The parameter names are scrolled with each pressing of the
"Mode/Enter" button.
• When the "Set" button is pressed briefly, the corresponding para-
meter value is displayed for 15 s. After another 15 s the unit returns
to the Run mode.
Programming mode
Setting of the parameter values
While viewing a parameter value pressing the "Set" button for more
than 5 s causes the unit to enter the programming mode. You can
alter the parameter value by pressing the "Set" button and confirm
the new value by pressing the "Mode/Enter" button. The internal
sensing, processing and output functions of the unit continue as if in
Run mode with the original parameter values unless a new value is
confirmed. The unit returns to the Run mode when no button has
been pressed for 15 s.
