3.2 Function

The proximity sensor SDBTMSX detects the magnetic field of the piston magnet.

In the sensing range of the proximity switch, a switching point can be pro

grammed. To set a switching point in the sensing range of the proximity sensor,

there are two options:

– Auto teachin

– Capacitive operating key

4.1 Electrical

WARNING!

Risk of injury due to electric shock.

• For the electrical power supply, use only PELV circuits in accordance with IEC

602041/EN 602041 (Protective ExtraLow Voltage, PELV).

• Observe the general requirements of IEC 602041/EN602041 for PELV cir

cuits.

• Only use voltage sources that ensure a reliable electric separation from the

mains network in accordance with IEC 602041/EN 602041.

4.2 Mechanical

• Mount the proximity sensor in the end position of the piston so that the end

position is in the sensing range of the sensor. If available, the orientation aid

provides the marking of the piston end position on the drive.

5 Commissioning

5.1 Automatic switching point setting: auto teach-in

Prerequisite: proximity sensor is in delivery status.

1. Mount the proximity sensor roughly in the end position 4.2 Mechanical.è

2. Connect the proximity sensor 4.1 Electrical.è

Proximity sensor is automatically taught in during operation, e.g. upon

initial commissioning of the complete system.

Application notes on auto teach-in

During auto teachin, each 100ms stop of the piston within the sensing range is>

output as a switching point. If the piston at this position reverses its direction of

movement and leaves the sensing range without further stops, this switching

point is saved temporarily.

If the piston stops 4x consecutively at the same position, reverses its direction of

movement and leaves the sensing range without further stops, this position is

saved as a final switching point. Auto teachin is complete.

The process described corresponds with the classic use case: proximity sensor

query at the end stop of the piston stroke or at the end stop of the customer

application.

If the piston stroke is smaller than the sensing range of the SDBTMSX, ensure

that the second reversal point of the piston is outside the sensing range during

auto teachin  Tab. 3.è

Application notes on auto teach-in

Auto teachin possible:

End position A

Auto teachin possible:

End position B

Auto teachin not possible. The

switching point must be set

using the capacitive operating

key.

Tab. 3

5.2 Manual operation using capacitive operating key

The proximity sensor is parameterised once it is installed.

• Be mindful of the surface temperature of the capacitive operating key and of

the drive.

• Avoid contamination and moisture on the proximity sensor.

5.2.1 Setting the switching point

1. Move the piston into the sensing range of the proximity sensor.

2. Actuate the capacitive operating key 3 times to activate setup mode.

3. Actuate the capacitive operating key once to switch to the menu item "Set

switching point".

4. Actuate the capacitive operating key once.

The current piston position is taught in as the switching point.

5.2.2 Setting the switching point with variable switching window width

1. Move the piston into the sensing range of the proximity sensor.

2. Actuate the capacitive operating key 3 times to activate setup mode.

3. Actuate the capacitive operating key twice to switch to the menu item "Set

switching point with variable switching window width".

4. Actuate the capacitive operating key once.

The current piston position is taught in as a switching point with approx.

2mm switching window width.

Every other keystroke increases the switching window width by approx.

1mm. A max. switching window width of 15mm is possible.

5.2.3 PNP/NPN switch-over

1. Actuate the capacitive operating key 3 times to activate setup mode.

2. Actuate the capacitive operating key 3 times to switch to the menu item

"Switch over between PNP / NPN".

3. Actuate the capacitive operating key once to switch between PNP> NPN or

NPN> PNP.

5.2.4 NO/NC switch-over

1. Actuate the capacitive operating key 3 times to activate setup mode.

2. Actuate the capacitive operating key 4 times to switch to the menu item

"Switch over between NO / NC".

3. Actuate the capacitive operating key once to switch between NO> NC or

NC> NO.

1) A switching point can only be set when the green LED is ON.

When the green LED is flashing at 1.5Hz, the magnet is located in the region of the function reserve. It is not possible to set a

switching point. The function reserve is required for the safe setting of switching points in the edge region.

When the green LED is OFF, the magnet is outside the sensing range. It is not possible to set a switching point.
