Description

Purpose and application

The DALI MCU digital potentiometer controls up to 25 DALI

electronic control gears and enables the manual operation of

luminaires with a DALI interface.

The potentiometer is mounted in ush device boxes.

Function

The potentiometer converts rotations of and pressure on the

rotary knob into DALI commands.

By switching multiple DALI MCU in parallel, the number of con-

trol locations or the number of controllable luminaires can be in-

creased. If multiple potentiometers are switched in parallel, the

commands of the potentiometer actuated last apply. Automatic

synchronization makes it possible to change the control location

without disturbing effects (e.g. brightness uctuations).

The DALI MCU can be supplied directly from the DALI control

line (= passive operation) or can deliver the required control

current itself when connected to the mains voltage (= active

operation).

Design

The potentiometer is made up of the following components:

• Rotary potentiometer (A)

• Connections (B)

– Control line (da+, da–)

– Neutral conductor (N)

– Phase (L)

• Housing with rotary knob (C)

Installation

Safety instructions

The potentiometer must only be installed and put into operation

by a qualied electrician. The applicable safety regulations and

accident prevention regulations must be observed.

WARNING!

Exposed, live cables.

Danger of electric shock!

• Only work on the potentiometer when it is de-

energised.

CAUTION!

Destruction of the potentiometer and other devices

through incorrect mounting!

• The potentiometer is designed for mounting in

ush device boxes. If mounted elsewhere, provi-

deadequate cable strain relief and insulation.

• Do not wire the control line with an external volt-

age, especially not a mains voltage of 230 V.

• Do not exceed the maximum number of ECGs

and total line length.
