Glass sensor
Glass sensor 1 – 4gang
Order no.: 168xx, 169xx
Operation and assembly instructions
1 Safety instructions
Installation and assembly of electrical devices may only be carried out by an electrician.
The glass sensor is not suitable for direct switching of mains voltage or low voltage.
Failure to observe these instructions may lead to damage to the device, fire, or other
hazards.
These instructions are an integral component of the product, and must be retained by the
end user.

3 Function
The glass sensor is intended for connection to systems for controlling building installations.
The glass sensor controls lighting, shutters, etc. when the sensor surfaces are touched.
The functions which are available depend on the system that is connected. We strongly
recommend coordination between the user and the installer with regard to the function
assignments.
Integrated into the glass sensor are white LEDs and one blue LED for status indication.
The LEDs can be operated with their factory setting or controlled via the connected system, if
this is allowed by the system.
The glass sensor must be connected to an adapter using the supplied ribbon cable.
The adapter can be used to connect interfaces to the systems KNX/EIB or radio bus, or supply
voltage from 8 to 30 V=. Other systems, such as relay circuits, can also be connected using an
adapter within the limits of the technical specifications.
4 Operation
The operation of functions must be set individually for each glass sensor depending on the
system. Two operating modes are typical:
Single-surface operation:
Switching lighting, etc. on/off and dimming it brighter/darker is carried out in toggle mode, i. e.
alternately by repeated touching of the sensor surface.
Two-surface operation:
Two opposite sensor surfaces form a functional pair. For example, touching the left-hand
surface switches/dims lighting on/makes it brighter, touching the right-hand surface switches it
off/ makes it darker.

Glass sensor
Operating the glass sensor
Touch a sensor surface (Figure 1, 1).
The underlying function is executed.
The actuation pulse is active for as long as the surface is touched. Depending on the
function, short and long touches can trigger different actions, e. g. switching/dimming.
5 Information for electricians
5.1Assembly and electrical connections
CAUTION!
Risk of destruction of the sensor or the connected system.
Fault voltages may occur when working under voltage.
Isolate from voltage before connecting the installation environment.
Mounting requirements
An adapter is required in order to connect the glass sensor to the building installations.
The choice of adapter depends on the specific interface and the connected installation system.
For instructions on connecting the adapter to the installation environment, please consult the
operating and assembly instructions for the adapter.
The user must provide a supply voltage of from 8 to 30 V= for the glass sensor.

Figure 3
Berker recommends mounting the glass sensor on a special wall box (Figure 3, 10). This wall
box 2gang for glass sensors provides enough room to house the adapter and the necessary
interfaces. The glass sensor is fastened to the wall box using a locking device. With deep-set
wall boxes, surface adjustment of up to 20 mm is possible by adjusting the retaining pins
(Figure 3, 12) on the setscrews (Figure 3, 11).
For mounting on smooth surfaces, adhesive points are included with the glass sensor; these
can be used for additional fastening of the glass plate after it is aligned.

Glass sensor
Mounting on 1gang flush-mounted boxes is possible. This involves more installation work,
because less installation space is available. In addition, the glass sensor must be fastened to
the wall using the supplied adapter ring.
The adapter ring (Figure 3, 9) must be used:
–for additional anti-dismantling protection
–for visual reasons, so that the distance from the wall will create a shadow gap
–for mounting on 1gang flush-mounted boxes
Setting the operating mode of the LEDs using jumpers
Factory setting of the blue LED:
Permanent indication of readiness for operation
The blue LED is lit when operating voltage is connected.
Factory setting of the white LEDs:
Indication of actuation
The corresponding LED is lit as long as a touch on the sensor surface is detected.
The LEDs can be controlled via the connected system. The white LEDs can be set e. g. as
status LEDs that indicate the operating state of the respective connected loads.
The blue LED can be parameterised as an orientation light that is lit at night, or as an operation
LED that is not lit at night so as not to be annoying.

Figure 4
To activate the LEDs via the connected system, the corresponding jumper (Figure 4) on the
back of the glass sensor must be adjusted.
J1 = Jumper 1 (Figure 4, 5) for operating mode of the blue LED
J2 = Jumper 2 (Figure 4, 6) for operating mode of the white LEDs
S
W
Figure 5
Move the corresponding jumper from the factory setting (Figure 5, W) to system control
(Figure 5, S).
If the jumpers for the LEDs are not in the factory setting position and there is no activation
via the connected system, then the LEDs remain unlit.
Preparing the glass sensor for mounting on a smooth surface
The adhesive points prevent the glass sensor from shifting on smooth surfaces.
Clean the attachment locations for the adhesive points on the back of the glass sensor
(Figure 2, 8).
Peel the adhesive points off of their backing and apply them to the four attachment points.
Clean the mounting surface.

Before completing mounting, align the glass sensor and press on the areas over the
adhesive points to fix it in place.
Connecting the glass sensor and mounting it on a wall box
The necessary adapter must be connected to a supply voltage and an interface. The wall box
2gang for the glass sensor is mounted at the installation location.

If necessary, measure the required surface adjustment (Figure 6, x). Screw the retaining
pins (Figure 6, 12) on the setscrews (Figure 6, 11) out by the surface adjustment x so that
they have a distance of 15 mm + x from the socket for the setscrews.
Set the surface adjustment precisely so that after mounting the glass sensor is firmly in
contact with the wall.
Connect the glass sensor to the adapter being used by means of the supplied ribbon cable.
Do this by inserting the plugs into the slots provided for that purpose in the glass sensor
(Figure 2, 4) and the adapter.

Glass sensor does not respond to operator control
Cause 1: The connection from the glass sensor to the adapter is faulty.
Check that the ribbon cable is properly seated and correct if necessary.
Cause 2: The glass sensor has no voltage supply.
Check the voltage supply and re-establish if necessary.
Cause 3: The polarity of the voltage supply connection is reversed.
Switch polarity of the voltage supply.
Cause 4: Condensation moisture on the surface of the glass sensor due to a temperature
difference from the ambient temperature.
