1. Safety

Intended use

The sensor must be used solely for the level

detection of liquids and solids with a dielectric

constant of at least 1.5.

The sensor must only be used for media against

which the housing material and sensor tip are

resistant.

Staff qualification

Only use staff who are trained for the activities

described. This applies in particular to assembly,

installation, conguration and troubleshooting.

Make sure that the staff have read and understood

these instructions.

Technical condition

Only use sensor in perfect technical condition.

Only use Baumer accessories.

Baumer will accept no liability for other

manufacturers’ accessories.

Risk of burns from hot media

During operation the sensor housing may warm

up to over 50 ºC. When working with hot media

provide protection against burns.

1 Sensor tip

2 LED

3 Connection with M12 plug

4 qTeach detector

An electrode integrated into the sensor tip forms

a capacitor with the environment. The medium

determines the capacity value depending on

its dielectric constant (DC values). A resonant

circuit occurs together with a coil in the sensor

electronics. Depending on the resonance

frequency measured and the programmable trigger

threshold, the switch signal is activated.

ATTENTION For material damage

4. Transport and storage

fCheck packaging and sensor for damage.

fIn the event of damage: Do not use sensor.

fStore sensor where it will be secure against

shock.

2 Limit level, max.

3 Limit level, min.

4 Run-dry protection

The sensor can be mounted on any point in the

vessel.

A sensor mounted at the top of the vessel (1)

ensures against overlling. Sensors attached

further down detect a maximum (2) or minimum (3)

limit level. A sensor attached at the bottom or on

the outfeed pipe (4) can protect a connected pump

against dry running.

If the sensor is mounted in a pipe, it is

recommended to use window trigger as the trigger

function. The adaptive trigger can have limited

functionality if it is mounted in a pipe.

8. Conguration

The sensor can be congured either via qTeach,

remote teach, FlexProgrammer or IO-Link. If

formation of foam or adhesion of media have to be

detected, a conguration with the FlexProgrammer

will be necessary.

If for both switch outputs different switch points or

media have to be congured, a conguration with

FlexProgrammer or qTeach is also necessary.

Configuring with qTeach (Standard version)

Via qTeach, the switch points SW1 and SW2 can

be congured independently. Switch output SW1

is NO (normally opened) and switch output SW2 is

NC (normally closed).

Conguration is only possible during the rst

5 minutes after connecting the voltage supply.

After that, qTeach will be locked.

Note: For a graphical overview of the conguration

procedure refer to “14.5 Conguration procedure

with qTeach” on page 16.

9Sensor is connected.

fHold screwdriver or other metal object on the

qTeach detector.

The LED is blinking magenta at 1 Hz for

3 seconds. For selecting the switch the LED

alternates between yellow and blue in 2 second

intervals.

fWhen the LED has the color of the desired

switch, remove the screwdirver or metal object

from the qTeach detector to select the according

switch:

SW1: yellow

SW2: blue

The LED is blinking in the selected color at 0.5 Hz.

fPut the sensor tip into the media and touch the

qTeach area.

The LED ashes in the selected color while the

teaching process is running.

10 / 48

www.baumer.com

For selecting the switching window the LED

alternates between green, cyan and white in

2 second intervals.

f

Hold screwdriver or other metal object on the

qTeach detector.

f

When the LED has the color of the desired

switching window, remove the screwdriver or

metal object from the qTeach detector to select

the according switching window:

Switching window ±12%, hysteresis 4%: green

Switching window ±6%, hysteresis 2%: cyan

Switching window ±3%, hysteresis 1%: white

The conguration is complete and the changes are

saved.

If the DC value of the media is too close to air, the

most narrow switching window has to be selected.

If the LED ashes red (indicating an error) or

if the conguration time of 5 minutes has been

exceeded, no changes are saved.

f

To restart the conguration disconnect and

reconnect the voltage supply.

Conguration via qTeach is enabled in the factory

settings and can be disabled by the user.
