Operating instructions

With the factory default setting, the mechanical BDI is always connected and ac-
tive on a DFA 127. If an additional electronic BDE-D is connected, the operating
mode will be set at the highest priority by a defined priority structure in the BDE.
The priority and the code shown in the following table apply to the operating
mode, whereby BDE2 (S2) and BDE1 (S1) represent the two STG input terminals
(à J7/1 + J7/2, Print BDE-M) for the mechanical BDE:
(L = interruption or 0V, H = +24V)

The BDE-D indicates the current operating mode.
If an operating mode that has no current priority is set on the BDE-D, status mes-
sage 62 is displayed.

(software reset). The LED lights up permanently after the reset.
