The programming unit connector socket with its key-
operated switch are built in the front of the WS 400-50
operator panel. On delivery, the connector socket is
protected by a plastic cap.
The key can only be removed when the contact is open.
The programming unit connector socket and the key-
operated switch are looped through 1:1 to the back of the
operator panel to allow the connection of a PLC, for
example.
