4 Product overview
4.1 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 downstream electronic
evaluation unit. The connection to the higher-level system is established via a
switching output.
The switching output can be configured to monitor a threshold value or a pressure
range. The PNP or NPN and the normally open (N/O) or normally closed (N/C) out-
put can be optionally set in this process.
4.1.1 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
EDIT mode – Setting or modification of parameters
TEACH mode – Acceptance of the current measured value to determine
switching points

NOTICE!
An unfavourable mounting position may impair the function of the product.
• Mount the sensor so that condensation from the compressed air lines cannot
accumulate in the device.
• Install the sensor so that it cannot be heated above the maximum permissible
operating temperature (plan for convection possibilities).
– Remove all transport packaging. The material used in the packaging has been
specifically chosen for its recyclability.
– Avoid applying force to the sensor housing during mechanical and pneumatic
assembly.
