Operating Instructions
Dupline Shutter Control Unit DRO 1U
7. General Information
The DRO 1U shutter control unit is a component of the Dupline installation system and
permits the control of shutter motors or drives of blinds or skylights. The contacts for Up
and Down movement are locked electronically and mechanically in the unit as well as by
the system software.
In addition, the DRO 1U is equipped with three inputs to which any electrically isolated
control contacts can be connected in order that their signals can be transmitted to the
Dupline net. As it is supplied by mains voltage, it can be fitted in a convenient local po-
sition, e.g. in switch socket boxes or shutter housings.
The green LED on the front indicates the proper functioning of the Dupline bus.
CAUTION!
For the control of motors it is absolutely necessary to use the ProLine
object „Roller blind“, since otherwise the required reverse delays cannot
be kept. This may lead to damages at the relay contacts and the motors
connected to them.
In addition, a permant supply of the device with voltage is necessary to
ensure proper functionality.
8. Coding
With the DHK 1 hand encoder each channel can be assigned any address between A1
and P8 via the flat-plug connector on the front of the DRO 1U. The allocation of the chan-
nels is as follows:
Functions which are not required should remain uncoded. Encoding the DRO 1U requi-
res neither a supply voltage nor the Dupline signal. Although the coding is permanently
retained, it may always be overwritten.
Addresses should be assigned in such a way that the Up and Down functions of the relay
receive
adjoining
addresses. You should always start with an uneven address figure.
Example:
The preferred switching direction in the event of a bus fault (“UP” = 1 or “DOWN” = 0)
