2.5. Roller blind control
2.5.1. Decentralized roller blind up-down function
• Function: Up-Down control of roller blind motors
• Application: Control of motors for roller blinds, sun blinds and roof windows through
Dupline modules G 3430 4249.
• Run time and Switch time individually adjustable
• Tilted blinds for sun blinds and priority control for example for wind sensor.
Description
The decentralized roller blind up-down control makes it possible to run Dupline roller blind control modules for
roller blind and sun blind motors. By organizing the up- and down-channels, the Mastergenerator ensures
undisturbed operation by preventing both directions from being activated at the same time and ensuring that
the delay time is observed.
The up-channel generally overrides the down-channel, ie if both are activated at the same time, the
Mastergenerator will execute the up-command.
Address configuration
The roller blind control can only be configured for an uneven channel number. This means that the up-channel
must have an uneven address number assigned to it and the down-channel must have an even address
number assigned to it. This reflects the address coding of the roller blind modules. Here the up-channel must
also have an uneven output assigned to it, while the down-channel must have an even output channel
addressed to it.
Note: When, in spite of correct address configuration, the motor runs in the opposite direction, the
corresponding connecting cables of the motor are reversed. In this case, correct connection must be ensured
- the channels must under no circumstances be reversed.
Operation
The up- and down-buttons configured for the addresses of the roller blind control allow very simple operation:
• By pressing the direction key once, the motor runs to the end position or for the duration of the roll time.
• By pressing the same direction key once more, the motor stops.
• By pressing in the opposite direction, the motor stops shortly and runs in the opposite direction until it
reaches end position or for the duration of the roll time.
When the option “Tilted blinds” is selected, the following options are available:
• If the direction key is pressed for less than three seconds, the motor stops when the key is no longer
pressed.
• If the direction key is pressed for more than three seconds, the motor runs to the end position or for the
duration of the run time. Here it is also possible to stop the motor by pressing the key once more or let it
run in the opposite direction by pressing the other direction key.
The Tilted blinds function makes it possible to activate the sun blinds shortly, so that instead of causing up- or
down-movement it changes the position of the tilting blinds.
Automating the roller blind control
Surely, many methods of automatic operation of roller blinds exist. Not only wind- and rain sensors, but also
light sensors and clock timers increase comfort through automatic functions.
Such functions should - if not configured as priority address - usually be made by means of Logic setup, where
primarily edge triggering is to be used which prevents continuous signals and allows permanent
operator control. Further details can be found in the chapter on Logic Setup.
Connection of several motors
Simultaneous activation of several motors can be achieved by:
1. connecting all motors to separate outputs and
2. assigning the same address to all up-channels as well as all down-channels.
We strongly advise against connecting two or more motors in parallel to one output channel.
The flexible way of controlling several motors centrally or group-wise is to use the Roller blind master
function. Further details are found in chapter 2.5.2.
