3 Functions and features

Theunitmonitorsthesystempressureinpneumaticandcompressedairnetworks

of machines and plants�

Applications

Compressed air (other media on request)

Typeofpressure:relativepressure

Order no. Measuring range Permissible

overpressure Bursting pressure

bar PSI bar PSI bar PSI

PQ0809 -1��1 -14�5��14�5 20 290 30 435

PQ0834 -1��10 -14�5��145 20 290 30 435

MPa = bar ÷ 10 / kPa = bar × 100

Avoid static and dynamic overpressure exceeding the given overload pres-

sure 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.NOTE:Riskofinjury!

4 Function

4.1 Processing of the measured signals

• Theunitdisplaysthecurrentsystempressure.

• It generates 2 output signals according to the parameter setting�

OUT1 •Switching signal for system pressure limit value�

OUT2

2 options

•Switching signal for system pressure limit value�

•Diagnostic signal (output 1 is inactive in case of a fault)�

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) 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FHxand

4.3 Diagnostic function

Output 2 is used as diagnostic output based on the DESINA specification if

[ou2] = [diA]�

• If there is no fault, the output is switched and carries Ub- �

• In case of malfunctions in the following areas, the output is inactive:

- short circuit in output 1�

- EPROM function�

- RAM function�

- parameter setting�

- processor function�
