1.2 1-point Teach-in
1. Selector switch to SET
Easy setting of the switching threshold.
Secondary condition:
Diffuse type = object absent
Through-beam = object present
Adjust diffuse type to the background without object
2. Operating mode
Teach-in active
3. In the basic menu, select
required mode by pressing
the arrow keys
4. 1-point Teach-in is shown on
the display
5. Adjust diffuse type fibre to the
background without object and
press Teach-in key
6. Teach-in successful
7. Selector switch to RUN
8. The switching threshold display
briefly flashes, and the basic
display is shown

Adjusts the switching threshold with + 5% according to the
light received.
Typical applications:
Standard applications,
no spurious effects expected,
max. system reserve.

In case of faulty input during Teach-in,
the following messages are shown:
Indicates that light intensity is too low
Indicates a non-detected,
moving object
Indicates a calculation error
Indicates an interruption
of the Teach-in

1. Selector switch to SET
Exact adjustment of the switching threshold to object and ambient
conditions, in any order.
1st step: Teach-in with object
2. Operating mode

3. In the basic menu, select
required mode by pressing
the arrow keys
4. 2-point Teach-in is shown on
the display

6. Press Teach-in key
5. 1st point: adjust diffuse type
fibre with object present
8. Press Teach-in key
7. 2nd point: adjust diffuse type
fibre to the background with-
out object
2nd step: Teach-in without object
The switching threshold is defined between the 1st and 2nd point.
1.3 2-point Teach-in

Typical applications:
Exact switching point,
switching threshold is adapted to the object and ambient
conditions, create low system reserves.
In case of faulty input during Teach-in,
the following messages are shown:
Indicates that light intensity is too low
Indicates a non-detected,
moving object
Indicates a calculation error
Indicates an interruption
