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

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).

Warning
Use only power sources which guarantee reliable electrical isolation of the oper
ating voltage in accordance with IEC/EN 60204-1. Consider also the general
requirements for PELV circuits in accordance with IEC/EN 60204-1.
Connect sensor.
– Consider the maximum permissible line length: 30 m (20 m for IO-Link).
