• For KNX PL-Link wiring (topology, allowed cables and cable length), see the
Desigo TRA installation guide, CM111043.
• Use the correct cables for the KNX PL-Link bus
• Do not interchange the wires of the KNX PL-Link cable.
– The red terminal is for KNX PL-Link +
– The gray terminal is for KNX PL-Link –
• Observe all local installation regulations.
• Use the earthing plate (quick slide connector) to connect an earthing cable in the
conduit box (in case a switch or a mains plug is in the same conduit box).
• The unit is not protected against accidental connection to AC 230 V.
• The installing tube must be sealed or cold or hot air may enter the conduit box
and cause faulty temperature readings by the internal sensor.
The room automation station must be running and an application must be loaded.
The application is not loaded on the room operator unit, but the room automation
station.
Download of the application is done using the SSA-DNT (Pack & Go) or the ABT.
For this purpose (or for service), connect the ABT to the room automation station
(USB or Ethernet).
All commissioning work is done via the PXC3... room automation station, using the
SSA-DNT or the ABT.
The ABT is never connected directly to a room operator unit.
When more than one QXM3.P36... room operator unit is on the same trunk of
the KNX PL-Link bus, manually commission is done as follows:
1. Connect the SSA-DNT or the ABT to the room automation station and
activate the online commissioning function.
2. Load the web page "KNX PL-Link identification".
Activate the identification function.
The room automation station now waits for a signal from the room operator
unit.
3. On the room operator unit, simultaneously press the upper left and bottom
right button for at least 5 seconds.
4. The page "System info" is displayed.
Go to the network function page (last line)
5. Press "Prog. Mode" (first line).
The display below "Prog. Mode" changes to "Enabled".
The tool identifies the current room operator unit that is operated and
assigns it.
After the device is commissioned, programming mode is automatically reset to
"disabled". Note: Programming mode also resets to "disabled" each time the
device restarts.
