Frequently Asked Questions - 75144830 HAGER

How do I operate the Hager 75144830 Touch/Glass sensor?

Briefly press a sensor button to execute the programmed function. The length of touch may trigger different actions (e.g., short for switching, long for dimming). Two operating modes are possible: single button (alternating functions) or two-button (pair of buttons for opposite actions).

How do I clean the sensor safely?

First, activate the cleaning function via an external telegram to block the device for 60 seconds (status LEDs flash). Then clean with a lightly moistened, lint-free cloth and possibly a mild glass cleaner. Avoid sharp objects and abrasive cleaners.

What are the mounting requirements for the Touch sensor?

The Touch sensor requires a double flush-mounted appliance box (single boxes not allowed). Screw the mounting frame to the box using the enclosed screws, align the marking TOP, connect the KNX bus, attach the device until it locks, and tighten the retaining screw with a Pozi-Drive size 0.

How do I mount the Glass sensor on a smooth surface?

Clean the adhesion points on the back of the sensor and the substrate. Stick the supplied adhesive dots to the four points, remove the protective film, align the sensor, and press firmly on the adhesive dots. For electrical connection, use a double installation socket (accessory).

How do I dismantle the Glass sensor?

If a retaining screw is present, slacken it with a Pozi-Drive size 0. Insert the enclosed dismantling tool into the center of the glass sensor and pull it evenly out of the anchoring (friction springs or mounting frame). Then disconnect the cables.

What should I do if the glass sensor does not lock in place?

The retaining pegs on the threaded pins may be adjusted incorrectly. Remeasure the surface compensation and adjust the retaining pegs so they are at a distance of 15 mm + x (without mounting frame) or 20 mm + x (with mounting frame) from the socket.

Why does my sensor not react to touch?

Check the connection to the KNX bus voltage for correct polarity and continuity. Ensure the bus power supply is active and the device is properly addressed. If the problem persists, reload the application software via ETS.

How do I commission the device?

After connecting and powering, press the programming button (rear side). The programming LED lights red. Assign a physical address via ETS3.0d or later, then load the application software. Write the physical address on the device label.

What accessories are available for this sensor?

Available accessories include: Wall box 2gang (Order No. 1871) and Floor temperature sensor/remote sensor (Order No. 161). These allow expanded mounting and additional temperature sensing.

What safety precautions must be observed during installation?

Only skilled electricians should install the device. Disconnect the power supply before working and cover live parts. Do not use sharp or pointed objects on the touch surface, and avoid acids or organic solvents for cleaning. Ensure compliance with KNX directives.

3 Function

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.

Planning, installation and commissioning of the device are carried out with the aid of KNX-certified software. Full functionality with KNX commissioning software version ETS3.0d onwards.

An updated version of the product database, technical descriptions and conversion programs and other auxiliary programs are available on our Internet website.

Intended use

• Operation of loads, e.g. light on/off, dimming, blinds up/down, brightness values, temperatures, calling up and saving light scenes, etc.
• Touch sensor: Installation in double flush-mounted appliance box according to DIN 49073
• Glass sensor: Installation in double installation socket for glass sensor (see chapter 6.3. Accessories)

Product characteristics

• The pushbutton functions switching, dimming, controlling blinds, value transmitter, calling up moods, etc.
• Operation through touching the sensor buttons
• LED to display status or actuation
• Integrated room temperature sensor for operation as controller extension
• Integrated bus coupling unit

4 Operation

The operation of functions or electrical consumers can be set individual for each device. Two operating modes are used:

- Single button operation: Switching on or off or dimming brighter/darker, e.g. of lighting, takes place alternately when the same sensor button is pressed repeatedly.

- Two button operation: Two sensor buttons next to each other form a function pair. Pressing the left button, for example, switches or dims lighting on or brighter, pressing the right one switches it off or makes it darker.

Operating a function or load

Consumers such as lighting, blinds, etc. are operated using the sensor buttons (2) and such operation depends on the programming of the device.

■ Press a sensor button.
The stored function is executed.

The actuation pulse is relative to the length of touch. Depending on the function, short and long actuations may trigger different actions, e.g. switching/dimming.

Cleaning the device

The device can be blocked for 60 s to prevent unintentional actions from being executed when the glass is being cleaned.

■ Recalling cleaning function by external telegram, e.g. from central
All the functions on the device are blocked for 60 s.
All the status LEDs of the sensor buttons flash.

i Cleaning with a lightly moistened, lint-free cloth, possibly with a mild glass cleaner. Do not use sharp objects or abrasive cleaning agents, e.g. scouring powder.

5 Information for electrically skilled persons

DANGER!

Electrical shock on contact with live parts in the installation environment.

Electrical shocks can be fatal.

Before working on the device, disconnect the power supply and cover up live parts in the working environment.

(7) Fibre-optic cable for operation LED
(8) Programming LED
(9) Programming button

The device is installed by screwing the mounting frame to the appliance box or to the wall. Increased dismantling protection is achieved by securing the device on the bottom of the mounting frame using a retaining screw.

Use double flush-mounted box. Mounting on single flush-mounted boxes or surface-mounted boxes is not possible.

• Align the mounting frame (10) and screw it to the appliance box or the wall (Figure 3). Observe marking TOP = TOP. Use the enclosed set of screws.
  ■ Connect the KNX bus voltage to the terminal (6).
  ■ Optional: Connect the external temperature sensor to the terminal (5).

Programming button and LED are accessible only from the back of the device. If possible, load the physical address into the device before the final installation.

■ Attach the device onto the mounting frame until it locks in place.
- Tighten the retaining screw (11) on the bottom of the mounting frame. Use a Pozi-Drive screwdriver, size 0.

(12) Adhesion points for adhesive dots
(13) Retaining peg

The adhesive dots prevent the glass sensor from slipping when mounted on smooth surfaces.

■ Free the adhesion points for the adhesive dots on the rear side of the glass sensor (12) from impurities.
■ Remove the adhesive dots from the carrier film and stick them to the four adhesion points.
■ Free the substrate of impurities.
■ Before mounting the glass sensor, remove the protective film from the adhesive dots.

Before completing mounting, align the glass sensor and press it in the area of the adhesive dots, in order to fix it in place.

Mounting and connecting the Glass sensor

Use the double installation socket (accessory). Mounting on single concealed sockets is not possible.

Optional: For increased dismantling protection or to increase the shadow gap to the wall, use the enclosed mounting frame (10). For this, lock the mounting frame onto the device from behind. Observe marking TOP=TOP.

Bus voltage is available at the installation location.

If necessary, measure the surface compensation. With deeper installation sockets, adjusting the retaining pegs (14) on the threaded pins (15) allows a surface compensation of up to 20 mm. Unscrew the retaining pegs (14) by the surface compensation x, so that they are at a distance of 15 mm + x from the socket for the threaded pins.

When the mounting frame is used, the distance for the surface compensation is 20 mm + x from the socket for the threaded pins.
