When the supply voltage has been applied, the unit is in the Run
mode. It monitors and switches the transistor outputs according to the

passes to the Display mode. Internally it remains in the operating
mode. Irrespective of this the set parameter values can be read:
• The parameter names are scrolled with each pressing of the
"Mode/Enter" button.
• 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

existing parameters until the change has been terminated.
You can change the parameter value by pressing the "Set" button and
