Operation- and
Assembly Instructions
1 Safety instructions
Electrical equipment may only be installed and fitted by electrically skilled persons.
Failure to observe the instructions may cause damage to the device and result in fire and
other hazards.
Danger of electric shock. Always disconnect before carrying out work on the devise or
load. At the same time, take into account all circuit breakers that supply dangerous
voltage to the device or load.
Danger of electric shock. Device is not suitable for disconnection from supply voltage.
Danger of electric shock on the SELV/PELV installation. Not suitable for switching SELV/
PELV voltages.
Danger of electric shock. Do not operate the insert without a cover.
These instructions are an integral part of the product, and must remain with the end
customer.

3 Function
Intended use
- Output Kanal 1 for switching light
- Output HLK for switching light, fans, air conditioners, thermostats and motors
- Operation with suitable cover
- Installation in appliance box to DIN 49073
Product characteristics
- Output HLK with potential-free NO contact for switching a second electric circuit, not SELV
or PELV
- Switch-on delay of output HLK can be switched off
- Run-on time of output HLK adjustable
- Connection of extensions possible
Function with motion detector or presence detector cover
Output Kanal 1
- Output is switched on if motions are detected and the brightness is below the threshold set
on the cover.
- Output remains switched on as long as motions are detected.
- Output is switched off if no more motions are detected and the run-on time set on the cover
has elapsed.
Output HLK
- Switch-on delay switched on: output is switched on independently of the brightness after
3 minutes if additional motions are detected approx. 2.5 to 3 minutes after the initial
detection.
- Switch-on delay switched off: output is switched on independently of brightness if motion is
detected.
- Output remains switched on as long as motions are detected.
- Output is switched off if no more motions are detected and the run-on time set on the insert
has elapsed.
Behaviour after a mains voltage failure
- Less than 0.2 seconds: switching state is retained
- longer than 0.2 seconds: both channels switch off. The behaviour after mains voltage
return depends on the cover used (see instructions for the cover).
4 Operation
Switching on with pushbutton cover (see Accessories)
Operation on the main device, 2-wire extension or on the installation button is identical.
i Extension operation is only possible if there is a cover fitted on the main device.
Outputs are switched off.
o Press the button.
Output Kanal 1 switches on.
When the switch-on delay for output HLK is switched off, output HLK switches on directly.
When the switch-on delay for output HLK is switched on, output HLK switches on with a
time delay, if output Kanal 1 is switched on for longer than 3 minutes.
Switching off with pushbutton cover (see Accessories)
Outputs are switched on.
o Press the button.
Output Kanal 1 switches off.
Output HLK switches off after the run-on time set on the insert elapses. The run-on time
begins as soon as output Kanal 1 has switched off.

Switching on in combination with motion detector or presence detector
Operation is performed with a 2-wire extension or an installation button. Only an overview of the
behaviour is provided here. For additional information, please refer to the instructions for the
cover in question. Operation with an extension is only possible is there is a cover fitted on the
main device.
Outputs are switched off.
o Press extension.
Output Kanal 1 switches on.
When the switch-on delay for output HLK is switched off, output HLK switches on directly.
When the switch-on delay for output HLK is switched on, output HLK switches on after a
time delay of 3 minutes, if no additional motions are detected for approx. 2.5 to 3 minutes
after the extension is operated.
Switching off in combination with motion detector or presence detector
i Combination with motion detector: outputs cannot be switched off.
i Combination with presence detector: the output HLK cannot be switched off.
Outputs are switched on.
o Press extension.
Output Kanal 1 switches off for 3 minutes. Any motions that are detected extend the time.
During these 3 minutes output Kanal 1 can only be switched on again via the extension.
5 Information for electrically skilled persons
5.1 Fitting and electrical connection
DANGER!
Electrical shock when live parts are touched.
Electrical shocks can be fatal.
Before carrying out work on the device or load, disengage all the
corresponding circuit breakers. Cover up live parts in the working environment.

(9) Installation button, NO contact
i Outputs Kanal 1 and HLK are not protected internally. For device protection, connect a
10 A miniature circuit breaker upstream.
o Connect insert according to connection diagram (picture 2).
i Output HLK can be used to switch a second external conductor.
i For extension units use the electric circuit of output Kanal 1.
i Illuminated installation buttons may only be connected if they have a separate N terminal.
o Connect the extensions, optional.
o Install insert in appliance box, terminals must be at the bottom.
o If multiple miniature circuit breakers supply dangerous voltages to the device or load,
couple the miniature circuit breakers or label them with a warning, to ensure release is
guaranteed.
o Set run-on time for output HLK (see Commissioning).
o Attach the frame and the cover.
o Switch on mains voltage.
5.2 Commissioning
DANGER!
Electrical shock when live parts are touched.
Electrical shocks can be fatal.
Before carrying out work on the device or load, disengage all the
corresponding circuit breakers. Cover up live parts in the working environment.
Switching switch-on delay for output HLK on and off
The switch-on delay for output HLK can be switched on or off. In the sate as delivered the
switch-on delay is switched on.
There is a pushbutton cover (see Accessories) on the HLK insert.
Outputs Kanal 1 and HLK are switched off.
o Press button over entire surface for longer than 3 seconds.
When the switch-on delay is switched on for output HLK, only output Kanal 1 is switched
on. After 3 seconds the switch-on delay is switched off; output Kanal 1 is switched off
again as confirmation.
When the switch-on delay for output HLK is switched off, both outputs are switched on.
After 3 seconds the switch-on delay is switched on; both outputs are switched off again as
confirmation.
Setting run-on time for output HLK
Output HLK remains switched on for the run-on time, after output Kanal 1 has been switched
off or no more motions are detected. The run-on time can be set in five stages between
2 minutes and 120 minutes.
