Product Usage Instructions

Safety Instructions

To avoid potential damage, please follow these instructions:

Electrical devices should only be mounted and connected to electrically skilled individuals.
During installation and cable routing, comply with regulations and standards for SELV circuits to prevent electric shock.
Ensure sufficient insulation between the mains voltage and the bus during installation. Maintain a minimum distance of at least 4 mm between bus conductors and mains voltage cores.
Do not connect any external voltage to the inputs during installation to prevent damage to the device and loss of SELV potential on the bus line.
This manual is an integral part of the product and must remain with the customer.

System information

This device is a product of the KNX system and complies with the KNX directives. Detailed technical knowledge obtained in KNX training courses is a prerequisite to proper understanding.
The function of this device depends upon the software. Detailed information on load-able software and attainable functionality as well as the software itself can be obtained from the manufacturer´s product database.
The device can be updated. Firmware can be easily updated with the Jung ETS Ser-vice App (additional software).
The device is KNX Data Secure capable. KNX Data Secure offers protection against manipulation in building automation and can be configured in the ETS project. Detailed technical knowledge is required. A device certificate, which is attached to the device, is required for safe commissioning. During mounting, the device certificate must be removed from the device and stored securely.
Planning, installation, and commissioning of the device are carried out with the aid of the ETS, version 5.7.7 and higher or 6.1.0.

Intended use

Outputs for polling of conventional, potential-free contacts in KNX systems and for sending telegrams to the KNX bus for reporting of states, meter levels, operation of loads, etc.
Outputs for activation of LEDs
Mounting in appliance box with dimensions according to DIN 49073 in combination with a suitable cover
When mounting behind switch inserts and push-button inserts, use an appliance box with sufficient installation depth

Product characteristics

Depending on the variant, two, four, or eight independent channels, which work as inputs or as outputs, depending on the ETS configuration
Common reference potential for all channels
Disabling of individual channels
Supply via the KNX bus, no additional supply voltage is necessary

Outputs

Connection of LEDs, e.g. LED lamp, 5 V DC, 2.2 mA
Short-circuit-resistant, overload-protected, and reverse-polarity protected
Switching outputs in parallel is possible, for loads with higher energy consumption

Inputs

Connection of potential-free contacts such as push-buttons, switches, or Reed contacts
Polling with an impulse current avoids contact fouling (image of an oxide layer) at the connected contacts
Operating functions: switching, dimming, controlling Venetian blinds, moods, or room temperature
Value transmitter for dimming, color temperature, RGBW, temperature, and brightness values
Transmission of the current input state after bus voltage failure
Connection of door or window contacts for the evaluation of the status of open closed, tilted, and grip position
Connection of Motion detector mini basic, leakage, condensation, and temperature sensors (see accessories)
Pulse counter with main counter and intermediate counter
Combination of adjacent input channels for the connection of push-button, door contact, and window contact
Logic functions

Mounting and electrical connection

Mount device
In secure operation (preconditions):

Secure commissioning is activated in the ETS.
Device certificate entered/scanned or added to the ETS project. A high-resolution camera should be used to scan the QR code.
Document all passwords and keep them safe.
- In secure operation: the device certificate must be removed from the device and stored securely.
- Mounting in a suitable appliance box. Observe cable routing and spacing

Bus connection

Connect the bus with a KNX device connection terminal to the KNX connection (1)(see figure 1).

Connection cables

Installation instructions

To avoid interference from EMC radiation, the cables of the inputs should not run parallel to cables carrying mains voltage or to load cables.
The voltage potentials of the connecting cables for the inputs and outputs are not galvanically isolated from the bus voltage.
The connecting cables lengthen the bus cable. The specification for the bus cable length (max. 1000 m) must be observed.
Do not connect the com connections of multiple push-button interfaces.
Use channels 1 and 2 for NTC temperature sensors (see chapter “Accessories” }
No series resistance is required for the connection of LEDs.

For the extension of the enclosed cable set (see figure 2), observe the maximum cable length (see chapter “Technical data” } Page 10). The following applies: the com cable for each cable set may not have a total length beyond 30 m in length.

Push-button interface

DANGER

The danger of electrical shock when mains voltage 230 V or other external voltages are connected!
Electric shocks can be fatal.
The device may be destroyed.
Only connect potential-free push-buttons, switches or contacts

Connect push-buttons, switches, contacts, LED or NTC to enclosed connecting cables (4) according to the connection examples; (see figure 3) to (see figure 7). The connection examples show the use of inputs and outputs.

To increase the output current, outputs can also be switched parallel to each other with the same parameterization; in the example here, (see figure 7) K1-K3 are switched in parallel.

Commissioning

Programming the physical address and application program

Switch on the bus voltage.
Press the programming button (2).
The programming LED (3) lights up.
Program the physical address with the ETS. The programming LED goes out.
Program the application program with the ETS.

Safe-state mode and master reset

Safe-state mode
The safe-state mode stops the execution of the loaded application program.

INFO: Only the system software of the device is still functional. ETS diagnosis functions and programming of the device are possible.

Activating safe-state mode

Switch off the bus voltage or remove the KNX device connection terminal.
Wait approx. 10 seconds.
Press and hold down the programming button.
Switch on the bus voltage or attach the KNX device connection terminal.
Wait until the programming LED flashes slowly.
Release the programming button.
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 as usual. If the programming mode is active, the programming LED stops flashing.

Deactivating safe-state mode
Switch off bus voltage (wait approx. 10 seconds) or carry out ETS programming.

Master reset

The master reset restores the basic device settings (physical address 15.15.255, 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.
