Connecting external push-buttons UP, STOP, DOWN
For the use from outside of the DC 3 an external switch (e.g. key-switch) can be connec-
ted. The push buttons UP and DOWN must have closing function. As the STOP function is
connected in the safety circle, it has to be connected as an opener. In case two 2x push-
buttons are connected, STOP inside and STOP outside must be switched in serial mode.
