Additional button No. 1
This button is built-in as standard and is located above the enabling button in the front area.
Its optimized ergonomic shape, as well as the tactile button beneath it, ensures it can be
operated easily and safely. This is usually done using the index finger.
Note on actuation!
The button must be actuated by pressing it down vertically, to an angle of between 0° and 15°. If the angle is
exceeded when actuating the switch, there is a possibility that the switch contact may be damaged, and the
switching cycles specified in the technical data will not be achieved.
Additional buttons No. 3 and No. 4
These buttons are installed on the grey housing. They can be controlled in a user-defined
way via the AS-i Bus.
Additional labelling of the buttons is an option for custom configurations.
