(Art. # 5314)
Dimming actuator with 4 PWM dimming outputs
Application with RGB / RGBW / Tunable White support
KNX IO 534 (4D)
Application area
The KNX IO 534 (4D) is a compact RGB / RGBW / Tunable
White dimming actuator with 4 PWM outputs.
The dimming actuator can be used e.g. for LED panels or stripes
with RGB / RGBW / Tunable White configuration or as 4 inde-
pendent PWM dimmer channels. Every configuration allows con-
trolling the channel by switching, rel. dimming and dimming
value.
Several comfort functions are integrated as well, including
scenes, slumber fading, staircase light and sequencer.
Two push buttons and three LEDs allow a local operation and a
visualization of the device state.
In addition to the output channels the device includes 16 inde-
pendent functions for logic or timer control.
1. Installation and connection
The KNX IO 534 is designed for installation on a DIN rail (35
mm) with a width of 1 units (18 mm). An installation-friendly de-
sign with pluggable screw terminals helps to reduce the cost of
commissioning. It features the following controls and displays:
This device is powered by the KNX bus. An external power sup-
ply is not necessary.
The device is not working without bus power.
A. KNX Programming mode
The KNX programming mode is activated/deactivated either by
pressing the flushed KNX programming button ❸ or by simulta-
neously pressing the buttons ❼ and ❽. Accessing the pro-
gramming mode via the device front buttons can be enabled /
disabled via the ETS® by changing the value of Prog. mode on
device front.
When the programming mode is active, the programming LED
❷ and LED Ch/M ❺light red.
B. Manual operation and status display
The LED Ch/M ❺lights up or flashes if the device is success-
fully powered by the KNX bus.
The channel for manual operation can be selected by pressing
button A ❼or B ❽short. The selected channel is indicated by
a continuous light or cyclic flashing of LED Ch/M ❺in green,
where the number of flash cycles indicates the number (A=1,
B=2, C=3, D=4) of the channel. On continuous light all channels
are controlled simultaneously in manual operation.
Pressing button A ❼or B ❽ for a long time switches to manual
operation for the selected channel of the dimming actuator. This
is indicated by continuous light or cyclic flashing of the LED
Ch/M ❺in orange. The flashing frequency corresponds again
to the channel selection.
In manual operation, the respective channel can be switched on
by pressing button On ❼ and switched off by pressing button
Off ❽short. In addition, it can be dimmed brighter with long but-
ton press on ❼ and darker with long button press on ❽.
The manual operation mode can be exit by pressing the buttons
(Esc) ❼and ❽simultaneously.
LED A ❹indicates the status of the dimming actuator. It lights
up when the channel is switched on and is off when the channel
is switched off.

4. Operating parameters of the dimmer chan-
nels
Maximum connectable power
The maximum dimmable power of the dimming actuator is es-
sentially limited by the power loss in the device. The maximum
current of 6 A can be distributed to any of the four channels.
With identical loads, 1.5 A per channel is thus permitted.
In Tunable White (TW) mode, two channels are used for each
function. In the standard setting, the total current of the two
channels is 100% of the maximum current of one channel. Thus
TW LEDs with double current can be connected here. Example:
- Channel 1: TW A cold white 3 A
- Channel 2: TW A warm white 3 A
- Channel 3: TW B cold white 3 A
- Channel 4: TW B warm white 3 A
PWM Phase position
The PWM signals of output channels 1 and 4 are in phase.
Channels 2 and 3 are also in phase, but shifted by 180° to 1 and
4.
Power dissipation
The dimming of luminaires is not possible without a certain
power loss in the dimmer. This power dissipation leads to a heat-
ing of the device and depends on several factors. In addition to
the output of the connected lamps, the current dimming value is
also taken into account. Thus, the loss with the luminaire
switched off is almost zero except for the leakage current. Even
at 100%, the power loss is relatively low and can be traced back
to the contact resistance of the output.
Between 0 and 100% the switching losses caused by the PWM
are added. Overall, there is a maximum power loss in the upper
dimming range.
The rated power of 144W refers to the maximum permitted ambi-
ent temperature for free installation. If there are other devices
next to the dimming actuator that emit heat, the power that can
be connected is reduced. Alternatively, the devices can also be
mounted at a small distance (approx. ½ TE = 9 mm). Suitable
spacers for the top-hat rail are available on the market for this
purpose.
Safety shutdown
The dimming actuator has an electronic fuse for overcurrent and
overtemperature. In both error cases, the output is switched off
and can be switched on again via a command if the error is no
longer present.
In addition, the device is also equipped with fuses against over-
current and overtemperature. This fuse stage protects connected
devices and surrounding materials against severe damage, but
leads to failure of the dimming actuator and can no longer be re-
set.
5. ETS database
The ETS database (for ETS 4.2 ETS and 5) can be downloaded
from the product website of the KNX IO 534 (4D) (www.wein-
zierl.de) or via the KNX online catalogue.
ETS parameter dialog
The following pages and parameters are visible in the ETS:
A. Description
This page shows the device description and the associated wir-
ing scheme.
B. General settings
Device name (30 Characters)
An arbitrary name can be assigned for the KNX IO 534 (4D). The
device name should be meaningful, e.g. „Living Room“. This
helps the clarity of the ETS project.
Send delay after bus power return
A send delay of telegrams after the return of the bus voltage can
be set via this parameter. In this case, telegrams from the device
are sent to the KNX bus in a delayed manner by the set time.
This results in a reduction of the bus load at a bus power return.
Other functions such as receiving telegrams of switching opera-
tions of the actuator are not affected by this parameter.
Prog. mode on device front
In addition to the normal programming button ❸the device al-
lows activating the programming mode on the device front with-
out opening the switchboard cover. The programming mode can
be activated and deactivated via pressing simultaneously both
buttons ❼and ❽.

©2019 WEINZIERL ENGINEERING GmbH Page 4/41
This feature can be enabled and disabled via the parameter
“Prog. mode on device front”. The recessed programming button
❸(next to the Programming LED ❷) is always enabled and
not influenced by this parameter.
Manual operation on device
This parameter is used to configure the manual operation on the
device. The manual operation mode can be disabled or activated
(with or without time limitation). The time limit defines the dura-
tion until the automatic return from the manual operation mode
back into the normal operating mode.
The device is in normal operating mode when the manual control
is not active. In the manual operating mode, received switching
telegrams are ignored. When the manual operation mode is ter-
minated (after expiry of the time limit or manually), the last state
of the outputs remains, until a new switching telegram is re-
ceived again.
The following options are selectable:
- Disabled
- Enabled with time limit 1 min
- Enabled with time limit 10 min
- Enabled with time limit 30 min
- Enabled without time limit
Heartbeat
Cyclic sending of values to the KNX-Bus, to indicate that the de-
vice is operational. For the Cycle time values between 1 min and
24h are selectable.
Alarm objects for error conditions
With this parameter, the following objects for the visualization of
error states become visible:
If an error condition is detected, all dimmer outputs switch off
and an ON telegram is sent via the respective object. The out-
puts are disabled for the duration of the error state, if it is re-
solved, the respective object sends an OFF telegram, and the
dimmer can be used normally again.
Overload is triggered from a load of 8A, overtemperature from a
measured temperature of 85°C in the load section. If no value is
received by the load section for longer than 3 seconds, the error
state "No supply voltage" is triggered.
PWM frequency
Here can be switched between 480Hz and 600Hz PWM fre-
quency. This parameter affects all dimmer outputs.
Device configuration
Here the general configuration of the device can be set; the fol-
lowing are available for selection:
- 1 x RGB
The device is operated as an RGB dimmer, 3 output
channels are occupied, 1 further output channel can
be used as a general dimmer or remain deactivated.
- 1 x RGBW
The device is operated as an RGBW dimmer, for
which all 4 output channels are occupied.
In this configuration, the output value of white is auto-
matically set, the value for white is calculated from the
current RGB value with the formula:
- 1 x Tunable White
The dimmer is used for a Tunable White consumer,
both cold and warm white LEDs occupy 1 output chan-
nel. 2 further output channels can be used as a gen-
eral dimmers or remain deactivated.
- 2 x Tunable White
The dimmer is used for 2 independent Tunable White
consumers, for this all 4 output channels are occupied.
- 4 x Common Dimmer
Each output channel can be used as an independent
dimmer.
Channel 1..4 configuration
Depending on the configuration of the device, these parameters
can be used to assign the output channels to the internal func-
tions. The assignment of the channels in the basic setting is de-
scribed in section 3 (Wiring scheme).
Device configuration “RGB”and “RGBW”
A. RGB A: General
Name (30 Characters)
An arbitrary name can be assigned for the channel. However,
this should be clear and meaningful, this makes it easier to work
with the associated group objects, because the given name is
displayed there as a label. If no name is assigned, the group ob-
jects are named “RGB A: …”.

G. RGB A: Dimming curve
This parameter page is used for fine adjustment of the dimmer to
different light sources.
All parameters on this page only affect the PWM value
of the output, not the dimming or output status value.
Dimming curve
Here it can be specified which PWM values are output by the
dimming outputs when the dimming channel has reached a cer-
tain color. The curve affects all outputs of the channel. The fol-
lowing options are available:

If the lock was activated by object 44, other received telegrams
for dimmer, automatic mode, slumber, scene function and se-
quencer are not executed.
In addition to the lock object, 2 priority objects become visible
when the lock function is activated, with which the dimmer can
be controlled independently of the lock. This makes it possible to
set an initial state without affecting other functions.
Example of the priority objects:
In the case of events in public buildings or in restaurants, the
normal operation can be set into an inoperative state by the lock
group object. Thus it is possible to lock during the lecture or con-
cert, switches that are accessible to unauthorized persons, in or-
der to prevent unmeant switching. Nevertheless, the individual
lamps can controlled by use of the priority object without cancel-
ing the lock.
Polarity of object
This parameter defines, if the lock should be activated by receiv-
ing a 1 or by receiving a 0.
The following options are selectable:
- Lock active on 1
- Lock active on 0
Behavior on start
This parameter configures, which state the output should set, if
the lock activates.
The following options are selectable:
- No reaction
- Switch to color
A parameter for adjusting the color appears.
This output state can still be changed by the priority object.
Behavior at end
This parameter defines, which state the output should set, if the
lock deactivates.
The following options are selectable:
- No reaction
- Switch to color
A parameter for adjusting the color appears.
- State before lock
This restores the original state before the lock was ac-
tivated. Telegrams received during the lock are ig-
nored.
- State without lock
Here the state of the last received telegram is re-
stored. This takes into account the received telegrams
during the lock. Thus, when the lock is deactivated, the
last received telegram is set.
K. RGB A: Sequencer
The sequencer can be used to create complex sequence pro-
grams consisting of up to 32 individual steps for the dimmer
channel. The individual steps can be activated under the follow-
ing starting conditions:
- At a fixed time of day
- After a waiting time from a previous step has elapsed
- By on/off telegram
- When receiving a parameterized scene number
When a step is activated, a color can be dimmed to or a scene
number can be sent, and a step or a whole sequence of steps
can be repeated cyclically.
The following objects are available for the general control of the
sequencer:

The following parameters determine the general behavior of the
sequencer:
Steps of sequencer
Number of steps (0...32) to be used
Resume sequence after man. operation
An activated sequence can always be interrupted or continued
via object 53, an ON telegram interrupts the sequence, and with
an OFF telegram it is continued.
A sequence is also interrupted after manual operation, i.e. after
commands for dimmer, automatic mode, slumber or scene func-
tion.

©2019 WEINZIERL ENGINEERING GmbH Page 16/41
In addition, this parameter determines how an interrupted se-
quence can still be continued:
- Only by object
The sequence can only be continued by object 53.
- After off-time
The sequence is continued after the set off-time.
- On next activated step
The sequence is continued with the next activated
step, the next step can be activated by object or time-
controlled.
Off-time
Only visible if the sequence is to be continued after off-time, with
this parameter the off-time can be configured.
Step after man. operation
This step is executed when resuming after manual operation, the
function of the set step is always executed, regardless of its oth-
erwise set starting conditions.
Polarity of object “Sequence on/off“
This parameter can be used to set the telegram value with which
the sequence can be switched on and off via object 54. If the se-
quence is switched off, any further activation of a step is disa-
bled.
Behavior on switching on
Here it is determined how the sequencer behaves when
switched on by object 54:
- No reaction
No function is executed, the sequencer waits for steps
to be activated.
- Step x
The function of the step is executed (independent of
the other set start conditions of the step), the se-
quence is then continued according to its configuration
from this step onwards.
Switching on also reactivates a sequence interrupted by manual
operation.
Behavior on switching off
Here it is determined how the sequencer behaves when
switched off by object 54:
- Complete actual step
If the sequencer is in a dimming process, it is com-
pleted.
- Step x
The function of the step is executed (independent of
the other set start conditions of the step).
- Stop immediately
If the sequencer is in a dimming process, it is stopped.
Apart from the set behavior when switching off, any further acti-
vation of a step after switching off is disabled until the sequencer
is switched on again by object 54.
Step 1-32
When a step is activated, its parameters for configuration ap-

In the text box at the top right with the content "Step x", you can
enter your own name for the step. This designation serves for
better orientation of the user and has no influence on the func-
tion of the step.
Start by time
This parameter is used to configure a temporal start condition of
the step.
- Disabled
Start condition not used
- Start at a fixed time of day
Here the time of day at which the step should start can
be entered. When using this start condition, the current
time must have been received via the following object:
Group Object
Type KNX
Size
Direction
GO 5 Time of Day - Set
10.001
3 Byte
From KNX
If no valid time was received by object 5, all
start conditions at fixed times of day are not
active.
The time is continuously updated by the de-
vice through its internal timers, but compo-
nent tolerances always result in a deviation
from the actual time. Therefore, the current
time should be sent to the device by a pre-
cise timer at least twice a day in order to
keep the deviation as small as possible.
- Start after last trigger
Here you can specify the time interval to wait after the
previous activation before executing the step. This
start condition is not available for step 1.
Start time
Here either the time day or the waiting time can be specified for
the execution of the current step, if a timed start condition is
used.
Start by ON/OFF telegram
When using this start condition, a separate object is available for
each step:

An ON telegram to one of these objects activates the respective
step, the sequence is then continued according to its configura-
tion from this step onwards.
An OFF telegram also activates this step, but resets the se-
quence at the same time.

When using automatic mode, the dimmer can be controlled via
the objects for automatic dimming, e.g. for light control or day-
light-dependent basic lighting.
In automatic mode the dimmer can be manually overridden by
the function blocks "Objects for controlling the color temperature
via brightness" and "Objects for color temperature/brightness",
as well as by the scene, slumber and sequencer functions. Dur-
ing manual override, values from the objects for automatic dim-
ming are ignored, each manual override restarts the fallback
time.
After the fallback time set in the parameter has elapsed, the val-
ues received on the objects for automatic dimming are pro-
cessed again.
Via object 30 or 110, the automatic can be switched on or off at
any time, it also serves as a status object for automatic opera-
tion.
Slumber function
The slumber function is only available in the "Dimmer" function.
The slumber function offers 2 different fade times each for
switching on and off via object. If this function is activated, a pa-
rameter page appears, which is explained in section H.
Lock function
The lock function can be activated or deactivated here.
This function is available in both "Dimmer" and "Staircase func-
tion" operating modes. If this function is activated, a new param-
eter page appears for further configuration, which is explained in
Section I in more detail.
B. TW A: Color temperature via brightness
TW B: Color temperature via brightness
In this operating mode the dimmer is controlled via brightness,
the color temperature is automatically adjusted according to the
current brightness and the 2 following parameters:
Color temperature at brightness 0%
Color temperature at brightness 100%
These two color temperatures are assigned to the two limit val-
ues of the brightness, in the range between 0% and 100% it is
linearly calculated and output.
