Safety notes
Safety extra low voltage 24 V DC!
Do not connect directly to the mains supply!
- Connection has to be carried out only by an
authorized electrical specialist
- Danger of violent pressure in handaccessible area
- Keep away People from the operating area of the
drive
- Keep away children from the control
- Observe pressure load diagram of the chain!
- Use only in dry rooms
- Only for inside mounting.
Use rain detector with danger of rain
(e.g. at domelights or roof windows)
- This product may not be operated without the
covering stoppers, which are delivered with
bracket sets
- Just use unchanged original D+H parts
- Observe mounting instructions of bracket set!
Observe enclosed r
ed safety slip!
Observe maximum pressure load of the chain!
Maximum pressure load of the chain is not
automatically identical with maximum pressure force
of the drive!

Performance features
- Micro processor controlled synchro electronics
BSY + for a precise synchronous run of up to
8 drives
- Individually programmable (via software SCS)
- SHEV-high speed function (fast-running
feature in OPEN-direction)
- Protection system for the main closing edge
- Power supply and BSY+ signal can be looped
through: with KA 34-BSY+ for max. 3 drives, with
KA 54-BSY+ for max. 2 drives
- Power supply is possible from both sides
- Locking relief after closing
Drive unit with 2,5 m silicone cable. Dependent on
the type of window, different bracket sets are
available separately.
Extent of supply
A synchronous group (KA-BSY+) can contain up to 8
drives, which communicate via bus. Each drive has
its own address, configurable with SCS.
The drive with the highest adress in a synchronous
group is the main drive. The main drive controls
the other drives, the sub drives. Differences in
forces between the drives of a group are balanced
by means of intelligent force and position control.
In the event that a drive malfunctions, all the drives
are automatically cut off.

Closing edge protection
In the "CLOSE" direction the drive has an active
protection for the main closing edge. If there is an
overload in the closing range 3 and 2, the drive runs
"OPEN" for 10 seconds, then "CLOSE" again. If after
three attempts closing is not possible, the drive
remains in this position.
In addition, the drive is equipped with passive
protection. The closing speed in closing range 2 and
1 is reduced to 5 mm/s.
Significantly greater forces can be
exerted at the secondary closing
edges. Danger of crushing hands and
fingers!
