• Each control circuit can supply DALI power for as many as 50 DALI devices
• The lighting system responds immediately and harmoniously when the brightness level is changed at either of
the control devices.
• All that while allowing for the required comfortable, easy and complete control over the lighting levels at any
time.
• Innovative Function to Power DALI Bus While Connected to AC Mains
• Powered by DALI Bus while not Connected to AC Mains
Safety & Warnings
• DO NOT install with power applied to device.
• DO NOT expose the device to moisture.

Operation

This device is a DALI MCU with built-in DALI bus power supply which can power DALI bus while connected with
100-240VAC mains. It also can be powered by DALI bus while not connected with AC mains.
There can be up to only 2 MCUs connect to AC 220V mains, the other MCUs powered by DALI bus.
Each control circuit simultaneously affords the integration of as many as 100 DALI ECG and of up to 4 DALI
MCU control devices (control points).

Switch ON/OFF

Click the rotary knob to switch ON/OFF light.

Increase/Decrease Light Intensity

Rotate the knob clockwise to increase light intensity from 1% to 100%, rotate the knob counterclockwise to
decrease light intensity from 100% to 1%.

Set the minimum brightness value

Press and hold down the knob over 5 seconds until the light flashes, to set the current brightness value as the
minimum brightness value for dimming, it is dimmable from this minimum brightness value to 100%.

Delete the minimum brightness value setting

Click the knob to switch off the light first, then press and hold down the knob over 5 seconds until the light
flashes, the minimum brightness value will be deleted. It is dimmable from 1% to 100% then.
