3 Functions and features
The device monitors the levels of dry bulk materials and liquids.
The device is particularly suited for monitoring plastic granulates.
The sensing face of the device is rated for temperatures up to 110°C and can therefore be mounted in
direct contact with the sight glass (without air gap).

4 Installation
For flush installation of non-flush units the sensor properties change and the sensor may
remain permanently switched (loss of function).

4.4 Notes on installation in tanks
uMount the device as shown:
In contact with the medium
Fig.5: Installation in contact with the medium
uIn case of liquids use a mounting adapter (e.g. E11033).
Not in contact with the medium
Fig.6: Installation not in contact with the medium

1: Miniature fuse
Use a miniature fuse according to the technical data sheet, if specified. Recommendation:
Check the safe functioning of the device after a short circuit.
For devices with two-wire technology:
The device is not short-circuit proof and not overload protected. Check the safe functioning of the
device after a short circuit.
The device is a class A product to CISPR 11. The device may cause radio interference in domestic
areas. Therefore the user may have to take appropriate measures, if necessary.

7 Settings
7.1 Basic teach empty state
Using the basic teach empty state, the device suppresses the installation environment. The basic
teach empty state resets the device, an adjustment teach already carried out is deleted.
uEmpty the tank until the level is at least 20 mm below the device.
Set the device as normally open (output closes when the tank is full):
uPress the button [OUT OFF] for 2-6 seconds.
wWhile pressing the pushbutton the LED flashes slowly. After releasing the pushbutton, the LED
goes out.
Set the device as normally closed (output opens when the tank is full):
uPress the button [OUT ON] for 2-6 seconds.
wWhile pressing the pushbutton the LED flashes slowly. After releasing the pushbutton, the LED
lights continuously.
The device 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.
7.2 Adjustment teach full state
An adjustment teach full state is necessary for aqueous media. The sensitivity of the device is
optimised. The adjustment teach full state can be repeated at any time, a basic teach empty state
already carried out is not affected.
A basic teach empty state must be carried out prior to the adjustment teach full state!
If it is not possible to empty the tank, a basic teach empty state can be carried out by simulating
the empty state (e.g. adjustment when not installed, adjustment at a higher position).
uFor optimum function of the device, carry out a modified basic teach empty state when the
tank is emptied the next time.
uFill the tank until the sensing face of the device is covered.
wFor NO the LED lights, for NC it goes out.
Set the device as normally open (output closes when the tank is full):
uPress the button [OUT ON] for at least 6 seconds.
wWhile pressing the pushbutton the LED first flashes slowly, after 6 seconds more quickly. After
releasing the pushbutton, the LED lights continuously.
Set the device as normally closed (output opens when the tank is full):
uPress the button [OUT OFF] for at least 6 seconds.
wWhile pressing the pushbutton the LED first flashes slowly, after 6 seconds more quickly. After
releasing the pushbutton, the LED goes out.
7.3 Modified basic teach empty state
The modified basic teach empty state is recommended in case of deposits in the tank. It allows
deposits to be largely suppressed.

Capacitive sensor KI0063
11
The modified basic teach empty state is also recommended if it has not been possible to carry out a
basic teach empty state (e.g. if the sensor is set up on a full tank).
The modified basic teach empty state can be repeated at any time, an adjustment teach full state
already carried out is not affected.
uEmpty the tank until the level is below the sensing face of the device.
wFor NO the LED goes out, for NC the LED lights.
Set the device as normally open (output closes when the tank is full):
uPress the button [OUT OFF] for at least 6 seconds.
wWhile pressing the pushbutton the LED first flashes slowly, after 6 seconds more quickly. After
releasing the pushbutton, the LED goes out.
Set the device as normally closed (output opens when the tank is full):
uPress the button [OUT ON] for at least 6 seconds.
wWhile pressing the pushbutton the LED first flashes slowly, after 6 seconds more quickly. After
releasing the pushbutton, the LED lights continuously.
7.4 Switching delays
uPress the buttons [OUT ON] and [OUT OFF] at the same time for at least 20 seconds.
wAfter 20 seconds the LED flashes. The device is now in the programming mode. The switching
output is enabled during programming.
uPress the button [OUT ON] or [OUT OFF] to set the delay time.
• Each push of the button [OUT OFF ] sets the next level down.
• Each push of the button [OUT ON] sets the next level up.
The set level is indicated by the number of LED flashes.
The following levels can be set:
Step Delay time in s LED display (flashing)
1 0 1x
2 5 2x
3 10 3x
4 15 4x
5 20 5x
6 25 6x
7 30 7x
uPress the buttons [OUT ON] and [OUT OFF] at the same time for at least 2 seconds or wait for 20
seconds.
wThe device applies the setting and goes back to the operating mode.
7.5 Lock / unlock
The device can be locked electronically to prevent unintentional settings. Factory setting: not locked.
Lock / unlock:
uPress the buttons [OUT ON] and [OUT OFF] at the same time for 10 s.
wAcknowledgement: LED state changes for a short time (the lit LED goes out briefly or the LED
which is not lit lights briefly).
