[ Ссылка ] - Product manager Helge Hornis shows you how to replace a failed KE4 compact safety controller on an AS-Interface Safety at Work network. The procedure is very simple, and doesn't require any special tools. Simply remove all the terminals from the failed safety controller, then remove its memory card. Insert the memory card into the replacement unit. Next, remove the failed unit from the DIN rail, and replace with the new unit. Insert all the terminal connections, and the memory card will be read in the new safety controller.
