QMX3... Wall-mounted sensors and room operator units for KNX PL-Link, KNX S-mode and KNX LTE-Mode CM2N1602en_08
Siemens Smart Infrastructure 2020-04-03
Manual commissioning (KNX PL-Link, without display)
The devices are equipped with a programming pin and a red service LED on the
back side (see page 4)
1. Short press the programming pin (<0.5 s).
The device goes into programming mode; the service LED is continuously on.
The tool identifies the current room operator unit that is operated and assigns it.
2. After the device is commissioned, deactivate the programming mode by shortly
pressing the programming pin (<0.5 s). The service LED goes off.
Note: Programming mode resets to “disabled” each time the device restarts.
1. Medium press the programming pin (>2 s and <20 s) to test the KNX PL-Link
connection. After releasing the programming pin, the test of the KNX PL-Link
connection starts; the service LED flashes (1/4 s on, 7/4 s off).
After approx. 10 s, the test result is displayed:
– If the test is positive, the LED goes on continuously.
– If the test fails, it flashes (1 s on, 1 s off).
2. Short press the programming pin (<0.5 s) to stop displaying the result of the
connection test. The service LED goes off.
Long press the programming pin (>20 s). The device is locked and reboots within
10 seconds. The room automation station deletes it from its device list. During this
time, it is safe to remove the device from the network.
Note: there is no LED activity during this operation.
If the bus plug remains connected, the device acts like a newly inserted device
requiring again automated or manual configuration.
This operation resets all user preference data and configuration settings to
factory default.
This operation is irreversible.
