DIM MULTI

Description
Purpose and application
The DIM MULTI sensor controls brightness at the workplace
and in offices to increase comfort and save energy.
DIM MULTI
The sensor is installed in T5/T8 fluorescent lamps or ceilings and is connected directly to control gear with a 1...10 V
interface.
The following application types are available, depending on
how the sensor is connected (see the connection diagram in the
fitting instructions):
• Alternative 1: One sensor controls and switches a load area.
• Alternative 2: Multiple sensors with a shared (coupled)
motion detector individually control and switch separate load
areas.
• Alternative 3: One sensor controls and switches a large load
area, and additional sensors are used as pure motion sensors to enlarge the detection area.
• Alternative 4: One sensor controls and switches a load area
and motion detection is deactivated.
Function
Light and motion sensor
Fitting instructions
The sensor measures the brightness in the area to be regulated
and keeps this to an adjustable set value by introducing artificial
light according to the amount of daylight available.
The sensor also detects the movements of people.
As daylight increases the artificial light is reduced. If the sensor
no longer detects any motion, it switches the luminaires off after
an adjustable delay period.
Design
A
The sensor is made up of the following components:
• Connections (A, on the back of the sensor):
–– L, N: Supply lines
–– 0 V, 1-10 V: control lines
H
–– ↑: Load
G
C
F
–– B: Control button or parallel circuit for shared motion
detection
–– Function selection switch
–– DIP switch

• Setscrew: Activating/deactivating motion detection (F)
• Setscrew: Switch-off delay time (F)
• Housing (H)
Installation
Safety instructions
The sensor must only be installed and put into operation by a
qualified electrician. The applicable safety regulations and accident prevention regulations must be observed.
WARNING!
Exposed, live cables or damaged housing.
Danger of electric shock!
• Only work on the sensor when it is de-energised.
CAUTION!
Destruction of the sensor and other devices through
incorrect mounting!
• Adhere to the connection diagram.

Attaching the sensor to the ceiling
Remove the base plate of the sensor.
Screw the base plate onto the ceiling.
Note: Follow step 5 to correctly align the base plate!
Connect the sensor, see “Connection diagram”.
Attach the sensor to the base plate.
Ensure that the button for setting the brightness setpoint
faces the window (the light sensor faces the room).
Attaching the sensor to the fluorescent lamp
Precondition: T5 or T8 lamps with a min. grid of 60 mm.
Insert the lamp clip into the sensor housing floor.
Attach the sensor to the lamp end with the lamp clip to avoid
weighing down the lamp excessively.
If necessary, adjust the sensor installation depth to the depth
of the grid luminaire by sliding the lamp clip in or out.
Pull the sensor off of the attached housing floor.
Connect the sensor, see “Connection diagram”.
…
†Attach the sensor to the housing floor again.
