4. Functions
4.1 General
The SwitchME series of KNX actuators is ideally
suited to control lighting, window blinds (for example) or other switch functions in a professional KNX
bus installation.
4, 8 or 12 channels can be switched simultaneously. The outputs switch a maximum of 16 A and can
also be manually operated.
The SwitchME KNX generally requires no additional power supply. The SwitchME 8 and
12 KNX only need an additional 24V DC power supply
if synchronous (RTS - real time systems) switching of several channels
is necessary. The autonomous switching of up to twelve devices is enabled by shutter contacts.

!Note: Voltage overload protection is integrated into the device. This halts active switch proce-
dures and retains the last relay position in the device memory. If a power drop falls into the
cut-off range, this function may prevent the deactivation of a non-switched relay. If the voltage
(capacity of the relay driver) again climbs into the active range, the relay can be reactivated
again in the memory after the interrupted state. If the load capacity is insufcient the delay time
for the switch change is approx. 0.4 s.
dOutput switch delay with additional power supply
max. delay time upon switch change (capacity load time)
SwitchME 8 KNX 100 ms
SwitchME 12 KNX 100 ms
!Note: With some applications a synchronous on/off relay switch is required, because exces-
sive delays are not permissible. In such cases an additional 24-30 V DC power supply can be
connected. The maximum anticipated power with an active relay is 24 mA, and 4 mA with an
inactive relay. If there is insufcient switching capacity, the switch delay for a status change is
approx. 100 ms.

prevention regulations must be observed. Failure to follow the instructions could result in damage to the
device, re or other hazards. Opening the device will render the warranty null and void. Motors up to
4 PS (no three-phase motors!) The place of installation should be well cooled with ambient air. Please
ensure the device is adequately protected from moisture, strong vibration and dust. Avoid contact with
rainwater and other liquids as well as with corrosive gases. Clean dust away regularly but do not use any
liquids such as alcohol, petrol, etc. and make sure not to touch connected contacts. If damage occurs
due to moisture or liquid, shut the device off immediately. Regularly check the connected wires and all
other connected cables and replace these in good time. For your own safety make sure every connection
is made via a fuse or an MCB (Main Control Block).
6.3 Start-up
Once the device has been wired up, the physical addresses can be assigned and the channels para-
metrised.
1. Connect the interfaces to the bus
2. Connect bus voltage
3. Press the programme button on the device (red programme LED illuminates)
4. Load the physical address from the ETS software via the interface (red LED voltages off once this has
been completed successfully) Load the application with the required parametrisation
5. Connect the power supply

of the ETS software)
7. Software
The databases of the SwitchME KNX from preussen automation enables the ETS3.0 software to per-
form the requisite congurations on the device. The device types are SwitchME 4 KNX, SwitchME 8 KNX
and SwitchME 12 KNX, the associated database name is: SwitchME KNX preussen.vd4. All interfaces
and their functions require parameters which you can take from the following descriptions. Each chan-
nel output of the switch actuator is independent from and identical to the others. The following section
describes the following channel output in detail.
Note: If you are using ETS2V1.3, import the database version "VD2", if you are using ETS3.0 then im-
port the versions "VD3" to "VD5".

8.3.3 "Staircase" function
cFigure 11: "Staircase" function
The staircase function causes the automatic switch-off of the switching procedure after a pre-set time.
The staircase time can be parametrised without restriction. There are other optional functions that can
be combined with the staircase function; these are described below.
`Options Start with "ON", stop with "OFF"
Start with "ON", without "OFF" function
Start with "ON/OFF", without stop
If the Start with "ON", stop with "OFF" function is selected, and the switch is activated, the light will be
turned on and the timer begins counting until the pre-set set point is achieved after which the light will
be turned off. The light can be turned off earlier by manually operating the switch.
If the Start with "ON", without "OFF" function is selected, and the switch is activated, the light will be
turned on and the timer begins counting until the pre-set set point is achieved after which the light will
be turned off. The light cannot be turned off by manually operating the switch.
If the Start with "ON/OFF", without stop function is selected, and the switch is activated or turned off,
the light will be turned on and the timer begins counting until the pre-set set point is achieved after
which the light will be turned off. The light cannot be turned off by manually operating the switch.
dStaircase light duration with bus
`Options NO
Changing the staircase light "OUT" delay not possible via bus, this is auto
matically controlled by database.
YES
Allows staircase light "OUT" delay to be performed by user via bus.

`Options NO
  YES(activated)
The warning function shows that the staircase light has almost expired and that the output will be de-
activated shortly. This occurs by switching off the output for the time period of the parametrised warn-
ing time. A small value of 1-3 seconds is recommended. Once the warning has abated, the light will be
turned on again for the pre-set advance warning time. This advance warning time enables the staircase
light time to be extended or the staircase to be vacated. It is recommended that there be dynamic pro-
gramming based on the actual circumstances (length of the staircase, next light switch, etc.). The total
switching time of the switch cycle is determined by adding up the three times.
dTime for "OFF": (0…255 min.)
Duration of the delay for the "OUT" switch of the staircase light in minutes.
dTime for "OFF": (0…59 sec)
Duration of the delay for the "OUT" switch of the staircase light in seconds.
8.3.4 ON/OFF delay function
cFigure 12: "On/Off" time delay
The on-delay will time delay the activation of the switching cycle. This means the output will only be
activated after a certain time period after the issue of the switch-on command. The off-delay will time
delay the switch-off.
These two functions can be combined.
dDelay time for switch-on: (0…255 min.)
Time period for delay of "On" switch in minutes.
dDelay time for switch-on: (0…59 sec)
Time period for delay of "On" switch in seconds.
dDelay time for switch-off: (0…255 min.)
Time period for delay of "Off" switch in minutes.

d Delay time for light protection: (0…59 sec)
Time period for delay of light protection in seconds.
!Note: The delay time for light protection starts once the "OFF" switch is activated and will only
switch to "ON" once this time has expired.
8.4 "Scene" function
cFigure 13: "Scene" function
The scene function is useful if room functions of various elements (e.g. light, heating, blind) are to be
synchronously changed.
To enable this the value must be assigned to the appropriate disk space (Scene A…L). Up to 5 scenes can
be programmed on each switch output.
In order to call-up a particular scene, the value for that scene must be sent to the communications ob-
ject for the scene function. In this context the value of the scene call-up however is always one number
lower than the pre-set scene number. The scene numbers can therefore have the values 1-64, but the
values of the call-up of the scene may only be 0-63.
5 scene memory options are available for each channel.
The 64 available scene numbers can be freely assigned to these 5 memory sets.
A scene will be called up if it receives a binary command (bit0-6 -> scene number, bit7=0) from the bus,
corresponding to a scene number. The seventh bit of the dataset must always be "0" in this context.
A scene will be stored if it receives a binary command (bit0-6 -> scene number, bit7=1) from the bus,
corresponding to a scene number. The scene status remains unchanged. The seventh bit of the dataset
must always be "1".

8.5 "Threshold " function
cFigure 14: "Threshold" function
The threshold value function enables two threshold values to be set. These two threshold values can be
set between 0 and 255. The switching status changes once a corresponding value is received from the
bus. There are three ways in which threshold values can be activated.
dActivation of threshold value 1 via bus:
YES enables threshold value 1 to be changed via the bus.
NO prohibits the change of threshold value 1 via bus.
dActivation of threshold value 2 via bus:
YES enables threshold value 2 to be changed via the bus.
NO prohibits the change of threshold value 2 via bus.
dThreshold 1 is (0…255)
The selection of the rst threshold value is between the range of [0…255]. The pre-set value is 80.
dThreshold 2 is (0…255)
The selection of the second threshold value is between the range of [0…255]. The precongured value is
180.
dObject value < lower threshold value
If the object value is less than the lower threshold value, the switch will respond in accordance with the
following options:
