  • Page 7: Disassembly

    Disassembly When measuring hot media, make sure that the device has cooled down prior to any dis- mounting or wear appropriate protective clothing to avoid burns. Switch off the power supply to the device before disconnecting the electrical connections. Once this is done, the device may be mechanically removed. Warning Opening pressurized lines might cause severe injuries.

  • Page 8: User Manual

    User Manual The device can be configured via the display module as well as the HART protocol. The following pages describe operation and configuration of the device using the display mod- ule. (valid from display module software version 2.0.0). An overview of the menue structure can be found on the last page of this document. Basics of the Operating Concept The display module consists of a dot-matrix display with 80x128 pixels as well as a...

  • Page 9: Display Mode / Measured Value Display

    The icon for the device status (see 6.2.3) as well as the bar graph is displayed in each op- erating mode. The bar graph always shows the state of the current output (4 mA = 0%, 20 mA = 100%). The contents of the header and the data area depend on the operating mode: Display of measured value ...
  • Page 10 The sequence of the screens with device data is as follows:  Counter (operating hour counter, maintenance timer)  Trailing pointer (pressure and sensor temperature)  ----- Measured value display (starting point) ---  Pressure measurement (rel/abs, nominal range, measuring range, damping) ...
  • Page 11 6.2.4 Display layouts You can configure the layout of the measured value display as well as the displayed infor- mation individually. There are five different layouts available: Designation Layout Description Example Five values Under the main value, four additional values are shown. Four values Under the main value, three additional values are shown.

  • Page 12: Menue Mode / Operating Menue

    Menue Mode / Operating Menue Press OK in the measured value display to go to the operating menue. Then the main menue appears in the display. In the operating menue you can navigate in the menues by using the arrow buttons. The selected menue item is indicated by triangles on the left and right.
  • Page 13 6.3.1 Displaying and entering parameters When entering parameters, either numerical inputs or a selection lists with fixed options is available. In general, the actual selection will be displayed first (view mode). Press OK to switch to edit mode to change the parameter. After this is done, the display will then switch back to view mode so that you can check the new setting.
  • Page 14 Figure 11: Elements when setting a numeric value You change the selected digit by pressing the button. The higher value digit is also increased or decreased when passing zero. For instance, you can easily go from 19 to 20 without having to edit two digits. Lower value digits are not influenced, unless the parameter limit is reached.

  • Page 15: The Menue Tree

    The Menue Tree In the following, the display and adjustment options are described by their position in the menue tree. An overview of the menue tree can be found on the last page of this docu- ment. 6.4.1 Main menue The main menue has the following entries: Menue entry Description...
  • Page 16 6.4.3 "Adjustment" menue The following functions are available for the adjustment: Menue entry Description Zero point Set device at ambient pressure to zero (0 bar rel) (not with abso- lute pressure devices) Position correction Correct zero point error due to installation position (not with abso- lute pressure devices) Lower adjustment Offset correction with applied reference pressure...
  • Page 17 6.4.3.3 Upper and lower adjustment The lower adjustment results in an offset of the characteristic curve. It thus affects zero and span of the measuring range. The upper adjustment changes the slope of the characteristic curve by correcting the span of the measuring range.

  • Page 19 Pressure unit The unit in which the measured pressure is to be shown can be selected from the following list: Unit Description mbar Millibar (1 mbar = 0,001 bar) Bar (1 bar = 1000 mbar = 10 Pascal (1 Pa = 1 kg/(m*s ) = 10 bar = 0,01 mbar) Hectopascal (1 hPa = 100 Pa = 1 mbar)
  • Page 20 6.4.4.2 “Display mode” submenue In the "Display mode" submenue, you configure the representation of the measured values and additional information on the display. With the menue item “Screen layout” you configure the information that is displayed and its layout. Up to five values can be displayed at the same time. In the additional menue en- tries "1st value"...
  • Page 21 6.4.5.1 Setting the damping Using an adjustable damping you can eliminate fast pressure changes or peaks from hav- ing direct influence to the output signal. The set value in seconds corresponds to the time constant of an exponential rise. After a sudden pressure change, it takes the damping time to reach 63.2% of the actual pressure at the output.
  • Page 22 6.4.5.3 Output function You can set the output function proportionally rising to the measured value (selection "Lin- ear") or proportionally falling (selection "Inverse"). You can also define the output signal by a table with interpolation point, e.g. to represent a tank shape (selection "Table"). There is also a square root output function implemented for flow measurement per differ- ential pressure (selection "Square root").
  • Page 23 Figure 15: Changing the table point Confirming inputs with a long OK is not available when editing table points. 6.4.5.6 Upper and lower current limit In the standard setting, the current output is limited at 3.8 and 20.5 mA, meaning a further drop or rise in the measured variable does not change the current.
  • Page 24 6.4.6.1 Min/Max values The min/max values save the maximum and minimum values of the different measurands until they are reset by the user. The menue item that shows the min/max value, can also be used to reset it. Some of the min/max values are also directly accessible from the measured value display in the device data (see 6.2.1).
