5 3 Functions and features The unit measures and monitors the system pressure in a plant. 3. Applications Type of pressure: relative pressure Order no. easuring range Permissible overload pressure Bursting pressure bar PI bar PI bar PI PIxx PIxx PIxx PIxx PIxx PIxx 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! Not suitable for use where the criteria for paragraph D0./63-03 of the 3-A standard have to be met. UK 4 Function The unit displays the current system pressure. It generates output signals according to the operating mode and the parameter setting. oreover, it provides the process data via IO-Link. The unit is designed for fully bidirectional communication. o 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 ( 4.5) 5

6 4. Operating modes The operating mode is defined by the wiring ( 6 Electrical connection) and automatically recognised by the unit wire operation OUT (pin ) Analogue signal proportional to pressure 4 0 ma or ma wire operation OUT (pin 4) OUT (pin ) witching signal for system pressure limit Communication via IO-Link 3 options: witching signal for system pressure limit Analogue signal proportional to pressure ma Analogue signal proportional to pressure ma 4. witching function (only for 3-wire operation) OUTx changes its switching status if it is above or below the set switching limits (Px, rpx). The following switching functions can be selected: Hysteresis function / normally open: [OUx] = [Hno] ( fig. ). Hysteresis function / normally closed: [OUx] = [Hnc] ( fig. ). First the set point (Px) is set, then the reset point (rpx) with the requested difference. Window function / normally open: [OUx] = [Fno] ( fig. ). Window function / normally closed: [OUx] = [Fnc] ( fig. ). The width of the window can be set by means of the difference between Px and rpx. Px = upper value, rpx = lower value. 6

7 P P FE P rp HY P rp 0 0 t Hno Hnc 0 0 t Fno Fnc UK P = system pressure; HY = hysteresis; FE = window 4.3 Analogue function The analogue output can be configured. [OU] defines whether the set measuring range is provided as ma ([OU] = [I]) or as ma ([OU] = [InEG]). caling can be set by means of the teach process or by entering a value for the parameters AP and AEP. Teaching the analogue start point [tap] or setting the parameter [AP] defines at which measured value the output signal is 4 ma (0 ma with [InEG]). Teaching the analogue end point [taep] or setting the parameter [AEP] defines at which measured value the output signal is 0 ma (4 ma with [InEG]). 7

8 inimum distance between [AP] and [AEP] = 5 % of the final value of the measuring range (turn-down :4); for PIx09: 5 % of the measuring span. I [ma] Factory setting I [ma] easuring range scaled AW EW P AW AP AEPEW P = system pressure, AW = initial value of the measuring range, EW = final value of the measuring range : [OU] = [I] : [OU] = [InEG] In the set measuring range the output signal is between 4 and 0 ma ([OU] = [I]) or between 0 and 4 ma ([OU] = [InEG]). It is also indicated: ystem pressure above the measuring range: -- Output signal > 0 ma if [OU] = [I]. -- Output signal 4 to 3.8 ma if [OU] = [InEG]. ystem pressure below the measuring range: -- Output signal 4 to 3.8 ma if [OU] = [I]. -- Output signal > 0 ma if [OU] = [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 [CAL]). Two calibration points can be defined (CP, CP). The two points are independent of each other. The two calibration points must be within the scaled measuring range ( 4.3 Pressure monitoring / analogue function). 8 P

9 The zero point calibration [COF] influences the calibration of the curve of measured values. Recommendation: set [COF] to 0 ( 9.4. [COF]), then calibrate the curve of measured values. After a change the calibration can be reset to factory setting ( 9.5. [re]). P' P = measured pressure P = modified measured value CP = calibration point CP = modified measured value for CP CP' CP = calibration point = curve of measured values with CP CP P factory setting = curve of measured values after calibration P' CP' P' CP' CP' CP CP CP CP P P P = measured pressure P = modified measured value CP = calibration point CP = calibration point CP = modified measured value for CP = curve of measured values with factory setting = curve of measured values after calibration P = measured pressure P = modified measured value CP = calibration point CP = modified measured value for CP CP = calibration point CP = modified measured value for CP = curve of measured values with factory setting = curve of measured values after calibration UK 9

10 4.5 IO-Link 4.5. 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 UB adapter cable. ore information about IO-Link Device-specific information IODDs necessary for the configuration of the IO-Link unit and detailed information about process data structure, diagnostic information and parameter addresses Parameter setting tools All necessary information about the required IO-Link hardware and software 5 Installation 5.

11 Before installing and removing the unit: ake sure that no pressure is applied to the system. Please note when the system pressure is displayed in % of the span: "0" does not mean that no pressure is applied to the system! The diaphragm must not be dented or cleaned with pointed or hard objects! The system seal must not be in contact with the diaphragm. The installation position of the sensor influences the hydrostatic pressure of the fill fluid in the capillary tube of the diaphragm seal unit. A zero shift (i.e. when no pressure is applied to the system, "zero" is not displayed as a measured value) as a consequence of the installation position of the sensor can be corrected via the menu ( 9.4.). UK Use in hygienic areas to 3-A: orientation of the unit in pipes and tanks Please note for optimised cleaning of the measuring element according to the 3-A criteria for hygienic areas: To ensure that the medium can completely flow off the area of the diaphragm seal when the pipes or tanks are empty, choose positions - 3 of the generally possible installation positions - 5 (see figure on the right). Use in hygienic areas to EHEDG: ake sure that the sensor is integrated into the system according to EHEDG. Use seals with defined seal compression!
