2 Safety instructions

• Please read this document prior to set-up of the unit� Ensure that the product is suitable for your application without any restrictions�

• If the operating instructions or the technical data are not adhered to, personal injury and/or damage to property can occur�

• Check the compatibility of the product materials with the media to be measured in all applications�

• Correct condition of the device for the operating time can only be guaranteed if the device is only used for media to which the wetted materials are sufficiently

resistant → 3.1 Applications.

• If the devices are used in gas applications with pressures > 362 psi (25 bar) the notes in chapter 3�1 for devices with the marking **

)

must be absolutely

observed�

The responsibility whether the measurement device is suitable for the respective application lies with the operator� The manufacturer assumes no liability for consequences of misuse by the operator� Improper installation and use of the devices results in a loss of the warranty claims�

With static overload pressure or max� 100 million pressure cycles�

)

For gas applications > 362 psi (25 bar) it is necessary to use devices with a measuring

range ≥ 3620 psi (250 bar)!

MPa = (measured value in bar) ÷ 10

kPa = (measured value in bar) x 100

Avoid static and dynamic overpressure exceeding the specified overload pressure by taking appropriate measures�

The indicated bursting pressure must not be exceeded� Even if the bursting pressure is exceeded only for a short time, the unit

may be destroyed. ATTENTION: Risk of injury!

Pressure Equipment Directive (PED): The units comply with section 3, article (3) of the Directive 97/23/EC and are designed and manufactured for "non-superheated liquids" of group 2 fluids in accordance with the sound engineering practice�

Restriction for stable gases according to PED → 2 Safety instructions.

4 Function

• The unit displays the current system pressure�

• It generates output signals according to the operating mode and the parameter setting�

• It moreover provides the process data via IO-Link�

• The unit is laid out for fully bidirectional communication� So, the following options are possible:

- Remote display: reading and display of the current system pressure�

- Remote parameter setting: reading and changing the current parameter setting�

- IO-Link parameter setting → 4.3

4.1 Communication, parameter setting, evaluation

OUT1 (pin 4)

• Switching signal for system pressure limit value�

• Communication via IO-Link�

OUT2 (pin 2) • Switching signal for system pressure limit value�

4.2 Switching function

OUTx changes its switching state if it is above or below the set switching limits (SPx, rPx)� The following switching functions can be selected:

• Hysteresis function / normally open: [oux] = [Hno] (→ fig. 1).

• Hysteresis function / normally closed: [oux] = [Hnc] (→ fig. 1). First the set point (SPx) is set, then the reset point (rPx)�

The hysteresis defined remains even if SPx is changed again�

• Window function / normally open: [oux] = [Fno] (→ fig. 2).

• Window function / normally closed: [oux] = [Fnc] (→ fig. 2). The width of the window can be set by means of the difference between FHx and FLx� FHx = upper value, FLx = lower value�

4.3 IO-Link

General information

This unit has an IO-Link communication interface which requires an IO-Linkcapable module (IO-Link master) for operation�

The IO-Link interface enables direct access to the process and diagnostic data and provides the possibility to set the parameters of the unit during operation�

In addition communication is possible via a point-to-point connection with a USB adapter cable�
