→ Interlock (two single-leaf swing
doors)
From software version 1.41, the DFA 127 allows the operation
of two single-leaf swing doors in interlock function with only
one BDE-D / BDI. One door can be opened only with AKI and
SSK when the other door is closed. An “OPEN” command is
saved by the closed door.
▪ The operating mode ‘Continuously open’ only opens
the appropriate door. For a complete opening of the
interlock area, e.g. to transport bulky goods, both
doors must be set to ‘Continuously open’.
▪ In manual mode, the door must be completely closed
again by hand. Only then the opposite door can open.
Consequently, this operating mode is not normally
recommended.
▪ All the usual DFA safety functions are also enabled in
‘Interlock’ mode.
▪ The use of direction-detecting trigger sensors is rec-
ommended to avoid needless opening movements.
