KNX S2
Actuator for drives up/down
Technical specifications and installation instructions
1. Description
With the Actuator KNX S2 with integrated facade control, the drives of shutters,
awnings, blinds or windows are controlled. The connected drives can be directly
operated with the switch pairs of the actuator.
With the potential-free design of the outputs, drives of up to 30 VDC and 230 VAC
can be controlled, as well as other systems (e.g. manual switch input of a motor con-
trol unit).
The automation for the shading or window ventilation is specified externally or in-
ternally. Internally, there are numerous options available for blocking, locking (e.g.
master-slave) and priority definitions (e.g. manual-automatic). Scenes are saved
and called up via the bus (scene control with 16 scenes per drive).
Functions:
•2 potential-free outputs for drives of shading or windows.
• Switch panel with switch pairs and status LEDs
•Position feedback (movement position, also slat position for shutters)
•Position storage (movement position) via 1-bit object (storage and call-up
e.g. via buttons)
•Controlviainternal or external automation functions
• Integrated shade control for each drive output (with slat tracking
according to sun position for shutters)
• Integrated window ventilation control
•Scene control for movement position with 16 scenes per drive (also slat
position for shutters)
• Mutual locking of two drives using zero position sensors prevents collisions
e.g. of shade and window (master–slave)
•Blocking objects and alarm reports have different priorities, so that safety
functions always take precedence (e.g. wind block)
•Manual or automatic control configuration per time or communication
object
•5 security objects for each channel
•Brief time limit (movement command blocked) and 2 movement limits
Configuration is made using the KNX software ETS. The product file can be dow-
nloaded from the Elsner Elektronik website on www.elsner-elektronik.de in the
“Service” menu.
1.0.1. Deliverables
•Actuator
1.1. Technical specifications
The product is compliant with the provisions of EC guidelines.
2. Installation and commissioning
Installation, testing, operational start-up and troubleshooting should
only be performed by an authorised electrician.
DANGER!
Risk to life from live voltage (mains voltage)!
There are unprotected live components inside the device.
• Inspect the device for damage before installation. Only put undamaged
devices into operation.
• Comply with the locally applicable directives, regulations and provisions for
electrical installation.
• Immediately take the device or system out of service and secure it against
unintentional switch-on if risk-free operation is no longer guaranteed.
Use the device exclusively for building automation and observe the operating inst-
ructions. Improper use, modifications to the device or failure to observe the opera-
ting instructions will invalidate any warranty or guarantee claims.
Operate the device only as a fixed-site installation, i.e. only in assembled condition
and after conclusion of all installation and operational start-up tasks, and only in the
surroundings designated for it.
Elsner Elektronik is not liable for any changes in norms and standards which may
occur after publication of these operating instructions.
2.1. Safety notice for automatic functions
WARNING!
Risk of injury from automatically moving components!
Parts of the system can be started by the automatic controls
and be a danger to persons.
• No persons may remain in the travelling range of parts
driven by an electric motor.
• Adhere to the relevant building regulations.
• Ensure that the return path/access to the building is not blocked
if spending time outside the building (danger of being locked out).
• Correctly decommission the system for maintenance and
cleaning work.
If there is a power outage, the system does not work. Therefore, shadings should be
moved to a save position if there are anticipated weather conditions, for example, if
this has not already been done by the automatic function (product protection).
If the power supply is removed, the connected drive switches off. When the power
is restored, the consumer remains switched off until a new movement command is
received by the actuator.
2.2. Connection
When installing and laying the cables for the KNX connection,
the regulations and standards governing SELV current circuits
must be observed!
2.2.1. Overview
The device is designed for series installation on mounting rails and occupies 3U.
Insulation properties of the clamp groups:
The Actuator KNX S2 is assigned to Overvoltage category III and Pollution degree
2 according to EN60664-1. According to this classification,
between 230 V power cables and FELV 4 kV surge voltage resistance and
between 230 V power cables and SELV 6 kV surge voltage resistance
must be provided. This provision must be observed during the installation.

Actuator KNX S2 2
Actuator KNX S2 • Version: 01.08.2022 • Technical changes and errors excepted. • Elsner Elektronik GmbH • Sohlengrund 16 • 75395 Ostelsheim • Germany • www.elsner-elektronik.de • Technical Service: +49 (0) 7033 / 30945-250
Non-labelled clamps may not be used, to avoid influencing the insulation proper-
ties!
Neighbouring clamp groups [1.1 to 1.3], [2.1 to 2.3] and [3.1 to
3.3] may not be used with mixed voltages, as there is only single
insulation between them.
2.2.2. Connection example KNX S2
Output A: Motor 230 V AC, up/down
Output B: External motor control unit. The Actuator KNX S2 is suitable for the use
with direct voltage (12 V DC, 24 V DC) through the potential-free output. In this case,
the U-connection is used as “Com”.
2.2.3. Display of operating status with the power supply LED
2.2.4. Status display with the channel LEDs
2.3. Notes on mounting and commissioning
Device must not be exposed to water (rain). This could result in the electronic being
damaged. A relative air humidity of 95% must not be exceeded. Avoid bedewing.
After the operating voltage has been applied, the device will enter an initialisation
phase lasting a few seconds. During this phase no information can be received or
sent via the bus.
For KNX devices with safety functions (e.g. wind or rain blocks), it is important to set
up periodical monitoring of the safety objects. The ideal ratio is 1:3 (example: if the
weather station sends a value every 5 minutes, the actuator must be configured for
a monitoring period of 15 minutes).
3. Addressing of the device at the bus
The device is supplied with the bus address 15.15.255. You can program another ad-
dress into the ETS by overwriting the 15.15.255 address or by teaching via the pro-
gramming button.
4. Disposal
After use, the device must be disposed of in accordance with the legal regulations.
Do not dispose of it with the household waste!
