DANGER
Risk of fatal injury from electrical current
.
All work on the device should only be carried out
by trained and skilled electricians. The country-
specific regulations and the valid KNX guidelines
must be followed.
½CAUTION
The device could become damaged.
- Only operate the device according to the
specifications stated in the Technical data.
- High voltages can cause damage. Never
connect the device to 230 V!
The push-button interface for KNX has two (art. no.
MTN670802) or four (art. no. MTN670804) inputs and
outputs. The inputs can be used to establish binary
statuses (via floating contacts) and the outputs can be
used to activate control lamps (low current LEDs).
For example, by connecting floating push-buttons or
switches to the inputs, you can use the KNX to perform
a range of functions including switching, dimming,
operating blinds and retrieving scenes, etc.
To check statuses, you can connect control lamps (low
current LEDs, e.g. in the switch) to the outputs and
activate them via KNX.
The contact supply voltage (SELV) for the connected
buttons/switches and the control lamps comes from
the push-button interface.
The push-button interface has a bus coupler.

General information
You can use this application to program the push-
button interface.
Up to two objects are available for each input.
Group addresses are managed dynamically. Maximum
no. of group addresses and associations: 150.
Application functions
This application offers a wide range of setting options
in order to execute numerous functions with a push-
button interface and controlled KNX devices (e.g.
dimming actuators, switch actuators etc).
Naturally, which function is possible in each individual
case depends on the KNX devices being controlled.
The functions of this application described here can
therefore only apply to those specific KNX control
functions. Here, only those tabs and parameters which
are of relevance to these control functions are
described.
You will find an overview of all the tabs, parameters
and the related adjustable values in the last section
"Parameters and settings“.
|The following description assumes that push-
buttons are connected to the inputs of the push-
button interface, and that (status) LEDs are
connected to the outputs.
|Adjustable times (staircase timer, ON delay,
OFF delay etc.) are adjusted via the time base
and time factor parameters. The actual time is
calculated by multiplying both values; e.g. time
base 1 second times time factor 3 gives
3 seconds.
If only one of these parameters is shown, no
time adjustment is possible for the parameter
setting selected.
Device selection
|First you must adapt the application to the
hardware used, since when the device
selection is toggled, parameter settings and
related group addresses are changed by ETS.
Select the "2-gang" or "4-gang" setting.
Operating mode
For the input functions, you can select between the
"Make contact" and "Break contact" operating modes.
Additional startup delay of the application
You can start up the application later after the bus
voltage has been switched on.
Debounce time
You can set a debounce time.
You can address two actor groups with 1 or 8 bits (1
byte) simultaneously.
With a 1 bit object type, the object value is first
inverted with each push-button action, then sent on
the bus, i. e. a "0" becomes a "1", and when the same
key is pushed again, a "1" becomes a "0". The device is
therefore switched on and off alternately. This
switching behaviour is called "toggling". An update or
change to the 1-bit/1-byte object value is possible via
the bus when another sensor switches the actuator
(e .g. via a two-way circuit or a central command). To
prevent "incorrect" toggling, you must load the status
of the actuator ("1" or "0") into the push-button
interface. To do this, connect the group address of the
second sensor to the switch/value object of the push-
button interface.
For 1-byte object types, you can set two values, which
are transmitted alternately after each push-button
action.
Two objects can also be sent in any combination when
the push-button is activated (1 bit / 1 byte).

Communication objects
You can select the following communication objects:
Per input:
You can address two actuator groups with 1 or 8 bits
simultaneously.
Depending on the parameter settings, one of the
following will be transmitted via the switch/value
object whenever a key is pressed:
– an ON or OFF telegram
– 1 byte values (0 % - 100 % in levels)
– 1 byte values (0 - 255) infinitely
– two objects, (1 bit / 1 byte) in any combination
sent via the switch/value object.
Communication objects
You can select the following communication objects:
Per input:
You can use the dimming function for the following:
– dim brighter and darker via one key (single-surface
dimming)
– either dim brighter or darker. You need a second key
(second input) to dim in the other direction (dual-
surface dimming).
You can use the corresponding key (input) to switch
the light on or off (press key briefly) or dim it (press key
for a longer period, the parameters for the exact period
can be set). When switching takes place, an ON/OFF
telegram is sent via the switch object. When dimming,
dimming up or dimming down is carried out via the 4-
bit dimming object; the parameters for the dimming
steps can be set. In addition, you can also transmit the
corresponding dimming step cyclically for a period of
time which can be set as required.
Common parameters for single-surface and dual-
surface dimming
Additional parameters for single-surface dimming
You can dim brighter or darker and also switch on or off
using a single key.
The current switching or dimming direction is always
dependent on the previous action, i. e. if switched off,
pressing the key briefly will switch the light on and vice
versa, and if the light has been dimmed up, prolonged
activation of the key will dim the light down again. On
release after prolonged activation, a stop telegram will
be sent via the 4-bit dimming object, thus terminating
the dimming procedure in the dimming actuator.
An update or change to the switch/object value is
possible via the bus when another sensor switches or
dims the actuator (e.g. via a two-way circuit or a central
command). To prevent the "wrong" switching/dimming
activity, you must load the status of the actuator into
the push-button interface. To do this, connect the
group address of the second sensor to the switch/
dimming object of the push-button interface.
A single command is sufficient to cycle through the
dimming range. This dimming procedure can be used
for most applications. The other possible dimming
steps (1/2 - 1/64 brighter or darker) dim brighter or
darker by the selected step. For example, to dim from
min. to max. brightness, you would need to push the
key for a prolonged period four times in succession if
the level set is 1/4.
