1 Preliminary note
1.1 Symbols used
Operating elements are indicated as follows:•
Example: [OUT OFF] = Button “OUT OFF“.
An instruction is indicated by “►“.•
Example: ►Mount the unit as shown.
A reaction to the action is indicated by “>“.•
Example: > Yellow LED on.
Important note
Non-compliance can result in malfunctions or interference.
2 Safety instructions
Please read the product description prior to set-up of the unit. Ensure that the•
product is suitable for your application without any restrictions.
The unit conforms to the relevant regulations and EC directives.•
Improper or non-intended use may lead to malfunctions of the unit or to•
unwanted effects in your application.
That is why installation, electrical connection, set-up, operation and•
maintenance of the unit must only be carried out by qualified personnel
authorised by the machine operator.

3 Functions and features
capacitive sensor used as level or proximity sensor•
detects without contact metals, almost all plastics, glass, ceramics, wood,•
paper, oils, greases, water and all hydrous materials and indicates their
presence by providing a switched signal
automatic adjustment to the medium to be detected by means of programming•
buttons
in level applications the sensor detects the medium through the tank wall (only•
suitable for non-metallic tanks)

The mounting adapter is to be ordered separately (order no. E12153 pack quantity
1 piece or E12154 pack quantity 10 pieces).
Figure A
Align the sensor (1), the cutouts (3) and (4) must show towards the mounting►
adapter.
Place the sensor with the lower part into the mouting adapter. The sleeves of►
the mounting adapter (2) must engage with the lower cutouts of the sensor (4).
First slightly press the lower part of the sensor.►
When the lower part of the sensor is well placed, completely press the sensor►
into the mounting adapter.
You can hear the sensor snap in.>
Figure B
The catch of the mounting adapter (5) must engage with the sensor.>
Fix the sensor with the enclosed screws (6) to the adapter.►
Figure C
Fix the mounting adapter including the inserted sensor to the tank at the►
requested height using suitable screws (7).

Do not place the mounting adapter including inserted sensor in the
immediate vicinity of metallic objects.
4.1.3 Installation on bybass pipes with a mounting adapter
The mounting adapter is to be ordered separately (order no. E12153 pack quantity
1 piece).
Fix the sensor to the bypass at the requested height with common cable ties.►
Insert the cable ties through the existing openings of the mounting adapter and►
tighten them firmly.

A: distance = 8 mm
B: width of the mounting
adapter = 36
Align the sensing face (1) to the object. Make sure that the programming but-►
tons (2) remain accessible.
Adhere to the indicated minimum distances to metallic objects opposite and►
beside the sensor (free space).
Non-metallic objects (e.g. plastic fixtures) are allowed within the lateral free►
space.
Fix the sensor with appropriate fixing screws to the designated location.►
If the sensor is installed behind a plastic plate (3), the object will be detected►
through the wall. Depending on the material used and the wall thickness the
sensor characteristics might change slightly. Do not use conductive plastics! If
possible, use thin walls.

5.2 Unit versions with auto-detect
On power up, unit types with auto-detect (types ...FAKG or ...FAOG...) detect
automatically if the output is connected to L- (p switching) or to L+ (n switching).
Disconnect the unit to acknowledge a change of the load connection.►
Automatic load detection is only ensured when a resistor is switched in
series to a closed mechanical contact.

7.1 Basic teach empty state
Using the basic teach empty state the unit suppresses the installation environ-
ment. The basic teach empty state resets the unit, an adjustment teach already
carried out is deleted.
Empty the tank until the level is at least 20 mm►
below the sensor.
31!nn
Set the unit as normally open (output closes when the
tank is full):
Press►[OUT OFF] for min. 2 s (max. 6 s).
While pressing the pushbutton the LED flashes>
slowly. After releasing the pushbutton, the LED
goes out. 2 - 6 s
Set the unit as normally closed (output opens when
the tank is full):
Press►[OUT ON] for min. 2 s (max. 6 s).
While pressing the pushbutton the LED flashes>
slowly. After releasing the pushbutton, the LED
lights continuously. 2 - 6 s
The unit is now ready for operation. For the detection of media with a low dielectric
constant (e.g. plastic granulates or oils) no further setting is required.
