or installation pushbuttons
Figure 4: Spacing between mains cable and
control cable
Minimum spacing between the mains voltage and
bus/extension wires: 4 mm (Figure 4).
Do not exceed permissible total load including
transformer power dissipation.
Operate inductive transformers with at least 85%
nominal load.
Mixed loads with inductive transformers: ohmic
load max. 50%.
Trouble-free operation is only ensured with
electronic transformers manufactured by us or with
dimmable inductive transformers.
q
CAUTION!
Danger of destruction from mixed
loads.
The dimmer and load may be
destroyed.
Do not connect capacitive loads,
e.g. electronic transformers, and
inductive loads, e.g. inductive
transformers, together on the same
dimmer output.
• Connect the load (Figure 5). Use the supplied
sprung screwless terminals. Flexible cable ends
must be tin-plated.
• Connect the device to KNX.
• If necessary, connect potential-free contacts to
the inputs (Figure 2).
• Install the device in the appliance box.

Commissioning
Load the address and the application software
• Switch on the bus voltage
• Assign physical addresses and load application
software into the device.
• Note the physical address on the device label.
Troubleshooting
Light has switched off
Cause 1: short-circuit in output circuit.
- Disconnect device from mains; switch off
associated circuit breakers.
- Eliminate short-circuit.
- Switch mains voltage on again.
- Switch device off and then on again.
€
i
When a short-circuit occurs the affected output
switches off. Automatic restart when short-circuit
is eliminated within 100 ms (inductive load) or
7 seconds (capacitive or ohmic load). After that
lasting switch-off.
€
i
When a short-circuit occurs during the calibration
process, the load calibrates itself again after the
short-circuit is eliminated.
Cause 2: load failure.
Check load, replace light bulb. For inductive
transformers, check primary fuse and replace if
necessary.
Cause 3: Output is disabled.
Cancel disabling.
Cause 4: bus voltage failure.
Check bus voltage.
Cause 5: mains voltage failure.
Check mains voltage.
Cause 6: overheating protection has tripped due
to overload or too high ambient temperature.
- Disconnect device from mains; switch off
associated circuit breakers.
- Let device cool down for at least 15 minutes.
- Check installation situation, ensure cooling, e.g.
provide distance from surrounding devices.
- Reduce the connected load.
Luminaires fl icker or buzz, proper dimming not
possible, device buzzes
Cause: wrong dimming principle set
- Installation or commissioning error. Disconnect
device and luminaire, switch off circuit breaker.
- Check installation and correct.
- If dimmer actuator calibrates itself incorrectly,
e.g. with highly inductive mains or long load
cables: preselect correct dimming principle
with commissioning.
Luminaires fl icker irregularly
Cause: ripple-control pulses from the electric
utility or distribution network operator.
Use audio frequency suppressors.
