6 Function
The sensor converts pneumatic pressure values (relative pressure) into electrical
signals, which can be used for control or regulating functions. Measurements are
carried out using a piezoresistive sensor element with a following electronic eval-
uation unit. Connection to the higher-level system is provided by 1 or 2 switching
outputs, an analogue output and/or an IO-Link interface. The switching outputs
can be configured for monitoring of a threshold value, a pressure range or a differ-
ential pressure. For each output, PNP or NPN and normally open (NO) or normally
closed (NC) can optionally be set. Through the IO-Link® interface, process values
can be read out and parameters changed and transmitted to additional devices.
6.1 Operating statuses
Operating status Function
RUN mode – Basic status after the operating voltage is
switched on
– Display of the current measured value
SHOW mode – Display of the current settings
– Display and resetting of the minimum and
maximum values
EDIT mode Setting or modification of parameters
TEACH mode Acceptance of the current measured value to
determine switching points

This function permits monitoring of a pressure value for constancy. The applied
pressure is constant in the range between [SP.Lo] and [SP.Hi], so the reference

is automatically determined. The result is a switching operation at
the output. The signal change signals the start of pressure monitoring. If the pres-
sure remains in the monitoring range [d.SP] around PRef, the pressure is stable.
When the monitoring range is left (e.g. caused by a leakage in the system), the
output switches back.

The parameters [SP.Lo], [SP.Hi], [t.obS] and [d.SP] can be configured by the user.
The greater [t.obS] is set, the more constant the pressure signal must be to estab-
lish the reference value PRef.
Function NO (normally open) NC (normally closed)
Switching function:
– 2 switching points (SP.Lo,
SP.Hi) for setting the valid

NOTICE!
An unfavourable mounting position can impair the function of the product.
• Mount the sensor so that no condensation from the compressed air lines can
gather in the device.
• Install the sensor so that it cannot be heated above the maximum permissible
operating temperature (plan for convection possibilities).
