JUNG 42911 ST Universal Push Button Module User Manual

1 Safety instructions

Electrical devices may only be mounted and connected by electrically skilled persons.
Serious injuries, fire or property damage possible. Please read and follow manual fully.
Use only the enclosed plastic screws for fastening to the supporting frame! Otherwise safe operation cannot be ensured. Electrostatic discharges can cause defects in the device.
This manual is an integral part of the product, and must remain with the customer.

2 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 loadable 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 Service 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 specialist 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.

The device is planned, installed and commissioned with ETS version 5.7.7 and higher or 6.0.5.

5 Operation

Operating a function or load
Depending on the programming, an operating area can have up to three functions assigned to it upper/left, lower/right, entire surface. Operation depends on the specific function.

￭ Switch: Short press on button.
￭ Dim: Long press on button. The dimming process ends when the button is released.
￭ Move shading: Long press on button.
￭ Stop or adjust shading: Short press on button.
￭ Open scene: Short press on button.
￭ Save scene: Long press on button.
￭ Set value, e.g. brightness or temperature setpoint: Short press on button.

6 Information for electrically skilled persons

6.1 Mounting and electrical connection

⚠ DANGER!
Electric shock when live parts are touched. Electric shocks can be fatal. Cover up live parts in the installation environment.

Snapping on the adapter frame With the adapter frame (3) in the correct orientation, snap it from the front onto the push-button sensor module (4) (see figure 1). Note the marking TOP.
Mounting and connecting the device

Supporting frame
Design frame
Adapter frame
Push-button sensor module
Fastening screws
Buttons
KNX device connection terminal
Box screws

Supporting frame side A for A design ranges, CD design ranges and FD design. Supporting frame side B for LS design ranges.

When the push-button sensor extension module is used (see figure 2): preferably mounted vertically. Use large supporting frame (14). When mounting on only one appliance box, countersink the lower screws into the wall, e.g. with a ø 6 x10 mm hole. Use supporting frame as template.

⚠ DANGER!
When mounting with 230 V devices under a common cover, e.g. socket outlets, there is a danger of electrical shocks in the event of a fault! Electric shocks can be fatal. Do not install any 230 V devices in combination with a push-button sensor extension module under a common cover!

￭ Mount supporting frame (1) or (14) in the correct position onto an appliance box. Note marking TOP ; marking A or B in front. Use only the enclosed box screws (8).
￭ Push frame (2) onto supporting frame.
￭ Mount the push-button sensor extension module (15) preferably below. Route connecting cable (16) between supporting frame and intermediate web.
￭ Push-button sensor extension module: Insert connecting cable (16) in the correct orientation into slot (17) in the push-button module. Do not crimp the connecting cable (see figure 2).
￭ Connect the push-button sensor module (4) to the KNX with the KNX device connection terminal (7) and push onto the supporting frame.
￭ Fix the push-button sensor module(s) to supporting frame using the supplied plastic screws (5). Tighten the plastic screws only lightly.
￭ Before mounting the buttons (6), program the physical address into the device.
The device should be used in an air-tight appliance box. Drafts cause incorrect temperature values to be measured.

6.2 Commissioning

Preconditions in secure operation
– 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.

Programming the physical address and application program
Project design and commissioning with ETS version 5.7.7 and higher or 6.0.5. The device is connected and ready for operation. The buttons are not mounted yet. If the device contains no or an incorrect application program, the blue operation LED flashes slowly.

Activating programming mode

￭ Press the push-button at the top left (9) and keep it pressed. Then press pushbutton at the lower right (10, 11 or 12): The operation LED (13) flashes quickly.
￭ Programming the physical address.
The operation LED (13) returns to its previous state – off, on, or flashing slowly.
￭ Programming the application program.
The operation LED flashes slowly (approx. 0.75 Hz) while the application program is programmed.

6.2.1 Safe-state mode

The safe-state mode stops the execution of the loaded application program.
If the device does not work properly – for instance as a result of errors in the project design or during commissioning – the execution of the loaded application program can be halted by activating the safe-state mode. The device remains passive in safe state mode, since the application program is not being executed (state of execution: terminated).
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.
￭ Press and hold the button at the bottom left and the button at the bottom right (see figure 3), depending on the device version (1 … 4-gang).
￭ Switch on the bus voltage.
The safe-state mode is activated. The operation LED flashes slowly (approx. 1 Hz).

Do not release the buttons until the operation LED flashes.
Deactivating safe-state mode
Switch off the voltage or carry out ETS programming.

6.2.2 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.
If the device – for instance as a result of errors in the project design or during commissioning – does not work properly, the loaded application program can be deleted from the device by performing a master reset. The master reset resets the device to delivery state. Afterwards, the device can be put into operation again by programming the physical address and application program.

Performing a master reset
Precondition: The safe-state mode is activated.
￭ Press and hold the button at the top left and the button at the bottom right (see figure 3) for more than five seconds until the operation LED flashes quickly (approx. 4 Hz), depending on the device version (1 … 4-gang).
￭ Release the buttons.
The device performs a master reset.
The device restarts. The operation LED flashes slowly.

Resetting the device to its default settings
Devices can be reset to factory settings with the 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 devices to lose their physical address and configuration.

7 Mounting operating areas, mounting buttons

The buttons are available as a complete set of buttons (see figure 4). Individual buttons or the complete set of buttons can be replaced by buttons with icons.
The physical address is loaded into the device. Place the buttons on the device in the correct orientation and snap in with a short push. Note the marking TOP.
