Note 2: Applicable for BRAIN/HART communication type. Set the switches as shown in the figure above to set the burn-out direction
and write protection. The Burnout switch is set to the H side for delivery (unless option code /C1 or /C2 is specified in the order),
and the hardware write protection switch is set to E side. The setting of the switches can be confirmed via communication. An
external zero adjustment screw can only be disabled by communication. To disable the screw, set a parameter before activating
the hardware write protect function. See each communication manual.
