Unit shall be supplied by a power source which complies with the requirements of

a limited-energy circuit in accordance with IEC/EN/UL/CSA 61010-1 or a Limited

Power Source (LPS) in accordance with IEC/EN/UL/CSA 60950-1 or IEC/EN/UL/

CSA 62368-1 or a Class 2 circuit in accordance with NEC or CEC.

3 Function and application

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 evalu

ation unit. Interfacing to the higher-level system is provided by 1 or 2 switching

outputs, an optional analogue output and an optional IO-Link interface.

The switching outputs can be configured for monitoring of a threshold value,

a pressure range or a differential pressure. The outputs can be set as PNP or NPN

and normally open (NO) or normally closed (NC). Via the IO-Link interface, process

values can be read out and parameters changed and transmitted to additional

devices.

3.1 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

Auto difference monitoring d_|¯|_

This funciton permits monitoring of a pressure value for constancy.

If the applied pressure is constant in the range between [SP.Lo] and [SP.Hi], the refer

ence pressure PRef is automatically determined. The result is a switching operation at

the output. The signal change signals the start of pressure monitoring.

If the pressure 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 establish

the reference value PRef.

Function NO (normally open) NC (normally closed)

Switching function:

– 2 switching points (SP.Lo,

SP.Hi) for setting the valid

work range

– 1 switching point (d.SP)

for determination of

the monitoring area

4 Installation

Note

Installation and commissioning are to be carried out only by qualified personnel

in accordance with the operating instructions.

 Remove all transport packaging. The material used in the packaging has been

specifically chosen for its recyclability.

4.1 Mechanical and pneumatic

Note

An unfavourable mounting position can impair the function of the product.

 Mount the sensor so that no condensate 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).
