Description
Purpose and application
The DIM MCU electronic potentiometer (manual control unit)
controls up to 50 dimmable electronic control gears and enables
the manual brightness control of luminaires.
DIM MCU
The potentiometer is mounted in flush device boxes.
Function
The potentiometer converts rotations into 1...10V voltage signals, which are transmitted to the dimmable electronic control
gears. Pressing on the rotary knob switches the mains voltage
on/off via a relay.

The potentiometer is made up of the following components:
• Rotary potentiometer (A)
• Connections (C)

–– Control lines (+, –)
–– Dimmed + switched phase (↓)
–– Phase (L)
• Trimmer (B)
• Housing with rotary knob (D)
