Area of use
Backbone coupler and line coupler
- Backbone coupler (BK): The physical address is the address of a backbone coupler
- X.0.0 and must match the logical topology of the KNX system.
- Connection of a mainline (HL) with a backbone line (BL). Alternatively with or without filter function. The coupler is logically assigned to the subordinate line.
- Observe the instructions in the technical documentation regarding the address.
- Line coupler (LK): The physical address is the address of a line coupler X.Y.0 and must match the logical topology of the KNX system.
- Connection of a line with a mainline (HL). Alternatively with or without filter function.
The coupler is logically assigned to the subordinate line. Observe the instructions in the technical documentation regarding the address.
- BK = Backbone coupler
- LK = Line coupler
- TLN = Bus device
- SV = KNX power supply
- DR = Choke
- Each line segment requires a separate power supply (SV) including a choke (DR).
Segment coupler and amplifier
Segment coupler (SK): The physical address is the address of a normal KNX participant X.Y.Z (Z≠0) and must match the logical topology of the KNX system. Division of a line (max. 256 participants) into independent line segments. Alternatively with or without filter function. The segment coupler is logically assigned to the subordinate line segment. Observe the instructions in the technical documentation regarding the address.
Amplifier (LV): The physical address is the address of a normal KNX participant X.Y.Z (Z≠0) and must match the logical topology of the KNX system. Division of a line (max. 256 participants) into independent line segments. Preparation and repetition of telegrams on a line, no filter function. Observe the instructions in the technical documentation regarding the address.
- SK = Segment coupler
- LV = Amplifier
- TLN = Bus device
- SV = KNX power supply
- DR = Choke
- Each line segment requires a separate power supply (SV) including a choke (DR).
Operation
- Deactivating the physical address filter function
- Press the Pass IA button.
- The status LED Mode briefly lights up red.
- The status LED Run displays the state of the filter functions, (see Figure 1).
- The filter is deactivated until the Pass IA button is pressed again.
- Deactivating the group address filter function
- Press the Pass GA button.
- The status LED Mode briefly lights up red.
- The status LED Run displays the state of the filter functions, (see Figure 1).

- Cover up live parts in the installation environment.
Mounting and Electrical Connection
Secure operation
- Secure commissioning in the ETS is activated.
- Remove the device certificate from the device and store it securely.
- Enter or scan the device certificate and add it to the project. Recommendation:
- Use a high-resolution camera to scan the QR code.
- Document all passwords and keep them safe.
- Mounting and connecting the device
- Observe cable routing and spacing
- Mount the device on the DIN rail.
- Connect bus lines to KNX device connection terminals (see Figure 1) observing the correct polarity.
- Connect the higher-order line to the lower device connection terminal (10).
- Power is supplied to the device via this terminal.
- Connect the subordinate line to the upper device connection terminal (1).
- Attach the cover caps to the KNX connections as protection against hazardous voltages.
- The subordinate line requires a separate power supply.
Commissioning
Programming the physical address and application program with ETS
- Switch on the bus voltage.
- Press the programming button (9) PROG..
- The programming LED (8) lights up.
- Programming the physical address.
- The programming LED goes out.
- Program the application program and filter table.
Safe-state mode and master reset
Activating safe-state mode
- The safe-state mode stops the execution of the loaded application program.
- Only the system software of the device is still functional. ETS diagnosis functions and programming of the device are possible. No telegrams are transmitted.
- Switch off the bus voltage or remove the KNX device connection terminal (10) of the higher-order line.
- Press and hold down the programming button for approx. 15 seconds.
- Switch on the bus voltage or attach the KNX device connection terminal. Release the programming button only after the programming LED starts flashing slowly.
- The safe-state mode is activated.
- By briefly pressing the programming button again, the programming mode can also be switched on and off in the safe-state mode. If the programming mode is active, the programming LED stops flashing.
Deactivating safe-state mode
- Switch off the bus voltage for approx. 15 seconds or trigger a restart via the ETS.
Master reset
The master reset restores the basic device settings (physical address 15.15.0,
firmware remains in place). The device must then be recommissioned with the
ETS. In secure operation: A master reset deactivates device security. The
device can then be recommissioned with the device certificate.
Performing a master reset
- Precondition: The safe-state mode is activated.
- Press and hold down the programming button for > 5 s.
- The programming LED flashes quickly.
- Release the programming button.
- The device performs a master reset, restarts and is ready for operation again after approx. 5 s.
Restoring the device to factory settings
The device can be reset to factory settings with the Jung ETS Service App.
This function uses the firmware contained in the device that was active at the
time of delivery (delivered state). Restoring the factory settings causes the
device to lose its physical address and configuration.
