4.2 Function
The position transmitter detects the magnetic field of the piston magnet and
continuously senses the piston movement in the sensing range.
The following output signals are available:
–analogue voltage signal: 0 … 10 V
–programmable switching output: 24 V
–IO-Link communication mode
5 Mounting
5.1 Electrical installation
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/EN 60204-1 for PELV circuits.
• Only use voltage sources that ensure a reliable electric separation from the
mains network in accordance with IEC 60204-1/EN 60204-1.

6.2 IO-Link Program output
The IO-Link function cannot be set with the operating keys on the device. All set-
tings for set-up, commissioning and parameterisation are made in the higher-level
controller of the IO-Link master.
6.3 Analogue output
The analogue output provides an output signal 0 … 10 V.
–The output signal is proportional to the path of the piston stroke in the sensing
range.

Tab. 4: Output signal of the analogue output
The analogue output is switched off during active IO-Link communication. The
output voltage is 0 V.
7 Operation
7.1 Magnetic direction detection and magnetic direction correction
During initial commissioning or after a reset to factory settings, the position
transmitter outputs the signals directly using the currently detected magnetic
direction.
The magnetic direction detection and, with it, the signal curve are corrected
during continuing operation in the following cases:
–The position transmitter was placed in operation in a position in which it was
not possible to detect a correct magnetic direction, e.g. due to ferromagnetic
materials near the sensor or within the drive or gripper.
–The position transmitter was rotated 180° in the slot after the magnetic direc-
tion was detected as stable.
Brief error signals may be detected at the sensor output if automatic correction of
the magnetic direction detection is required è 8.2 General malfunctions.
