Mounting information
- The drive set is fully configured ex factory.The
drives must be reconfigured using the software
SCS in the event of changes to the ex-factory
configuration (e.g. when removing a drive from
existing set or integrating a new drive).
- Mount the drives whilst under zero stress. With
that, an even load distribution is provided by all
the drive chains.
- At vertical active pulling application (e.g. for a
skylight) the forces must be rearranged by
software SCS.
- If after mounting, the distance X is greater than 23
mm, null balance with software SCS is neccesary.
Closure Ranges will shift in relation to new zero
point.
≥ 23 mm ?
Troubleshooting
Visual inspection:
Only one main drive is allowed. The main always
has the highest addressing of all the drives; this
can be found on the type plate of the drive. Subs
are numbered downwards from the main, so that in
a group of two drives, for example, the main is no.
2 (M2) with a sub no. 1 (S1) drive. Please note that
this only applies in the ex-factory configuration. As
soon as the drives are re-addressed with SCS, the
ex-factory addressing no longer applies.
Wiring:
Is the drive or drive group wired properly?
See connection plans.
Diagnostics with SCS software:
The SCS software and a BSY+ interface is
required for further troubleshooting or
configuration.

Functional description
ACB interface
ACB is used for secure communication between
the drive and compatible D+H control systems. It
enables activation, diagnostics and configuration
with perfect position, directly from the control
panel. In this process, all status messages, such
as the OPEN and CLOSED signals, opening
stroke and drive errors, are transmitted to the
control panel.
The ACB bus is based on an open Modbus RTU
protocol via which the actuator can be directly
controlled and queried. Modbus addressing,
assignment and naming of the drives can be done
directly via the ACB bus lines using the SCS
software.
Further information can be found in the D+H ACB
Planning Manual.
BSY+ synchronised electronics:
A synchronous group 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.
X
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.
