Connecting the device without running time
detection
• Connect the bus line to the bus terminal (Fig. 3).
• Connect the mains voltage supply (Fig. 3).
Observe the admissible load rating (Technical data).

• Connect the drives (Fig. 4).

Connecting the device with automatic running
time detection
If programmed and connected accordingly, the shut-
ter actuator detects the running time of the individual
blinds/shutters and stores them. The actuator mea-
sures the voltage against the connected N terminal at
the drives and can thus recognize the limit positions.
In operation, the shutter actuator can adapt itself to
changes in the running times of the blinds/shutters
that are due, for instance, to ageing of the motors.
Information for qualified electricians
The running time detection function is activated in the
software.
The blinds/shutters are not blocked.
• Connect the bus line to the bus terminal (Fig. 3).
• Connect the mains voltage supply (Fig. 3).
CAUTION
When the N conductor is connected and when
the concerned output is energized without inter-
ruption for a prolonged time due to retriggering,
the device may heat up excessively.
Risk of irreparable damage to the device.
Do not connect the N conductors.

The automatic running time detection can-
not be used for 110 V AC drives, for DC
drives, for drives with electronic limit
switches and for drives connected to the
outputs via isolating relays.
Only for 230 AC drives with mechanical
limit switches.
i
Connect only one drive to an output.
