4 Function
4.1 Process measured signals
• The unit generates 2 output signals according to the parameter setting�
OUT1 Switching signal for system pressure limit�
OUT2 Analogue signal (4���20 mA, 20���4 mA)�
• The unit displays the current system pressure�
Analogue display: circular scale with pointer�
Digital display (alphanumeric display, 4 digits)�
• In addition, an LED ring with one of the following display options is available:
Display of set point and reset point�
Trend display (rising pressure / falling pressure)�
Lag indicator function for maximum value or minimum value�
Display of pulsating signals and pressure peaks�
4.2 Pressure monitoring / switching function
OUT1 changes its switching state if it is above or below the set switching limits
(SP1, rP1)� The following switching functions can be selected:
• Hysteresis function / normally open: [OU1] = [Hno] (→ fig. 1).
• Hysteresis function / normally closed: [OU1] = [Hnc] (→ fig. 1).
First the set point (SP1) is set, then the reset point (rP1) with the requested difference�
• Window function / normally open: [OU1] = [Fno] (→ fig. 2).
• Window function / normally closed: [OU1] = [Fnc] (→ fig. 2).
The width of the window can be set by means of the difference between SP1 and rP1�SP1 = upper value, rP1 = lower value�
6
1 2
P = system pressure; HY = hysteresis; FE = window
4.3 Pressure monitoring / analogue function
The analogue output can be configured�
• [OU2] defines whether the set measuring range is provided as 4���20 mA
([OU2] = [I]) or as 20���4 mA ([OU2] = [InEG])�
Scaling can be set by means of the teach process or by entering a value for the parameters ASP and AEP�
• Teaching the analogue start point [tASP] or setting the parameter [ASP] defines at which measured value the output signal is 4 mA (20 mA with [InEG])�
• Teaching the analogue end point [tAEP] or setting the parameter [AEP] defines at which measured value the output signal is 20 mA (4 mA with [InEG])�
Minimum distance between [ASP] and [AEP] = 25 % of the final value of the measuring range�
UK
7
Factory setting Measuring range scaled
P = system pressure , MAW = initial value of the measuring range, MEW = final value of the measuring range
1 : [OU2] = [I]; 2 : [OU2] = [InEG]
In the set measuring range the output signal is between 4 and 20 mA ([OU2] = [I]) or between 20 and 4 mA ([OU2] = [InEG])�
It is also indicated:
• System pressure above the measuring range:
-Output signal 20 to 20�5 mA if [OU2] = [I]�
-Output signal 4 to 3�8 mA if [OU2] = [InEG]�
• System pressure below the measuring range:
-Output signal 4 to 3�8 mA if [OU2] = [I]�
-Output signal 20 to 20�5 mA if [OU2] = [InEG]�
4.4 Customer-specific calibration
The customer-specific calibration changes the curve of measured values
compared to the real measured values (shifting / change of the gradient, (→ 9.4.6)
[CAL])�
• Two calibration points can be defined (CP1, CP2)� The two points are independent of each other� They must be within the measuring range and not in the extended display range�
• The zero point calibration [COF] influences the calibration of the curve of
measured values� Recommendation: set [COF] to 0 ( (→ 9.4.1) [COF]), then
calibrate the curve of measured values�
After a change the calibration can be reset to factory setting (
8
• P = measured pressure;P‘ = modified measured value
• CP1 = calibration point 1;CP1‘ = modified measured value for CP1
• CP2 = calibration point 2;CP2‘ = modified measured value for CP2
• 1 = curve of measured values with factory setting
• 2 = curve of measured values after calibration

5.4 Ventilation diaphragm
5.4.1 Function ventilation diaphragm
The ventilation diaphragm enables the relative pressure measurement since barometric and temperature-dependent pressure fluctuations between the measuring cell and the environment are compensated for�
The ventilation diaphragm is protected against damage by a screwed filter cover with circumferential ports�
For a correct functioning of the diaphragm please take the following into account:
► Remove soiling and cleaning agents immediately using plenty of limedeficient splash water�
If the sensor is in a cooling stage:
► Avoid contact of the diaphragm with liquids:
> Avoids negative pressure in the measuring system resulting in a slightly falsified measured value and additional strain on the diaphragm�
