Calibration procedure
Measuring (AdaptivDIM)
When commissioning for the first time, the dimmer will calibrate accordingly to the connected load
(duration max. 60 sec.).
In factory default state or after a reset, the calibration starts with the Automatic mode, which
means AdaptiveDIM automatically determines the stable lowest brightness, the ideal characteristic
curve and the cutting method during the initial setup.
After changing the type or number of luminaires, the device must be recalibrated.
On Casambi enabled devices the measurement process can be done on the fly via the APP.
Meassure mode
Um die Lastart zu ermitteln muß ein Messmodus gewählt werden.
Ein einmessen erfolgt bei der erstmaligen Inbetriebnahme und kann bei Bedarf manuell über die
Casambi App angestoßen werden.

Load numbers - max. number of luminaires of the same type
In order to optimally use the dimmer and to see how many luminaires of the same type can be
used, it is possible to determine the load number of the luminaire. To do this, measure with a
single luminaire.
The determined load number can be found in the Casambi APP under Parameters, it shows the
quantity of possible luminaires of the same type.

NOTE
During the meassurement the connected luminaires may flicker. This is system-
conditioned and not a defect of the device. The calibration must be completed and shall
not be interrupted by switching off the device, otherwise the procedure must be
repeated.
NOTE
A load number is only available for lamp type LED. The integrated load number display
is a recommendation and helps to determine the maximum number of luminaires.

Lamp type - currently used dimming mode
The load will be automatically calibrated (Adaptive DIM) and set to the best parameters. If a mode
wants to be set manually or another light source is used, a new calibration can be started in the
app (via the Measure mode parameter) and a calibration method is selected.
If the load used is not compatible with the selected load type, the system switches to a compatible
mode.

All wiring and the pushbuttons must be insulated for the maximum supply voltage. Ensure the
appropriate contact protection after installation. All push-buttons of the well-known switch
manufacturers are suitable.
A push-button style must be selected, before the button inputs may be configured.
Push-button style
Through the parameter Push-button style the functionality of the button inputs are defined.
To change the push button style, proceed as shown below
Open Casambi App
Double tap on the device icon

Dimming characteristics
Power rating of retrofit dimmers

power load
Ohmic
trailing edge
approx. 100% of the rated power 600 VA
LED
trailing edge
approx. 70% of the rated power 420 VA
LED
leading edge
approx. 20% of the rated power 120 VA
As a rule:
Example 28x W (rated power LED) + 20% power factor = 135 VA power
to be processed. Specifications depend on the light source used and may
vary upwards and downwards.
Derating
The specified max. power rating applies to installation in a sufficiently ventilated location.
In case of lower heat dissipation, e.g. in cavity walls, flush-mounted/ junction boxes, as well as in
case of mutual heating of several devices, the max. power rating is reduced accordingly.
In case of overtemperature automaticly derating takes place, which means the power will reduced
depending on the temperature. Status-LED is indicating over temperature and the brightness of
the lamps decreases.
Short circuit
In case of a short circuit, the unit switches off the output. Every 30 seconds, the unit tests whether
the short circuit has been eliminated.If it has, the unit restarts automatically. If the fault is still
present after 5 min, the unit is switched off.
Instruction: Switch off the unit and eliminate the short circuit.
Noise emission
It may occur that the dimmers cause acoustic noise when they are used under unfavourable
conditions or with certain luminaires. Our dimmers are extreemly low noise design, noise is always
an indicator for the overal quality of the used luminaires. Try to change luminaires with other /
better characteristics.
Flickering
The device works propperly under regular power quality conditions. Flicker or other visual effects
may occur in case of insufficient mains conditions like fluctuations, Jitter or also power control
signals. Power grid immanent effects are not a defectives of the device.
Check your local grid.
