Emergency unlocking

7.1

Electrical emergency unlocking

Due to a short-term interruption of the opera-
ting voltage, the locking bolt automatically
moves into the "OPEN" position. This can be
achieved e.g. by linking a key-button in the
+U_b (red) line.
7.2 Mechanical emergency
unlocking
The emergency open axis is accessible on
both sides of the blocking element so that the
locking bolt can be moved into the "OPEN"
position using a screwdriver for slotted
screws.
Due to the low transmission, a high number
of revolutions is required.
If the operating voltage is still available for
the blocking element, the bolt is moved into
the position "OPEN" after a few revolutions of
the motor-powered emergency opening axis.
