1 Safety instructions

Please read the product description prior to installing 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 may occur.

Please check for all applications that the product materials (see Technical•

data) are compatible with the media to be measured.

For gaseous media the application is limited to max. 25 bar / 2,5 MPa.•

For the scope of validity cULus: The device shall be supplied from an isolating

transformer having a secondary Listed fuse rated as noted in the following table�

2 Function and features

The pressure sensor detects the system pressure�•

It shows the current system pressure on its display�•

It generates 2 output signals according to the set output configuration�•

OUT1: switching signal for system pressure�-

OUT2: switching signal for system pressure or diagnostic signal�-

Applications

Type of pressure: relative pressure

Order no. Measuring range Permissible

PSI 0��1450 4350 9400

Static and dynamic overpressures exceeding the indicated overload pres-

surearetobeavoided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 can be destroyed�

NOTE:Riskofinjury!

For gaseous media the application is limited to max� 25 bar / 2,5 MPa�

3 Function

3.1 Switching function

OUTx changes its switching state when the set switching limits have not been

reached or have been exceeded (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) with the requested differ-

ence�

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 SPx and

rPx� SPx = upper value, rPx = lower value�

8.2 Setting the output signals

8.2.1 Setting the output function

Select [OU1] and set the switching function:►

[Hno] = hysteresis function / normally open,

[Hnc] = hysteresis function / normally closed,

[Fno] = window function / normally open,

[Fnc] = window function / normally closed�

Select [OU2] and set the output function:►

[Hno] = hysteresis function / normally open,

[Hnc] = hysteresis function / normally closed,

[Fno] = window function / normally open,

[Fnc] = window function / normally closed�

[dESI] = Output 2 is used as a diagnostic output�

8.2.2 Setting the switching limits

Select [SP1] / [SP2] and set the value at which the output switches�►

Select[rP1]/[rP1]andsetthevalueatwhichtheoutputswitchesback.►
