Page 2: General Information
In addition to this instruction, be sure to observe all statutory requirements, applica- ble standards, the additional technical specifications on the accompanying data sheet (see www.labom.com) as well as the specifications indicated on the type plate. General Safety Notes The installation, set up, service or disassembly of this device must only be done by trained, qualified personnel using suitable equipment and authorized to do so. -
Page 3: Devices With Diaphragm Seal
Devices with Diaphragm Seal Remove the protective cap or protective wrapping from the diaphragm only just before in- stallation to prevent contamination or damage. The diaphragm must not be touched. Do not place the device on its diaphragm. Even small scratches or deformations may negatively influence the zero point or other characteristics of the device. -
Page 4: Electrical Connection
Electrical Connection Complete the mechanical installation before you connect the device electrically. Set up all electrical connections while the voltage supply is switched off. Output (2-wire) 4...20 mA (20...4 mA) = 12…30 VDC Permissible supply voltage ≤ (U Permissible load - 12 V) / 22 mA Circular connector M12 Cable gland... -
Page 5: Operation
Operation During operation, take care that the device remains within its intended pressure and tem- perature ranges. No other monitoring is necessary. -20…80 °C Permissible ambient temperature: Optionally, you can order devices with an extended ambient temperature range of -40...80 °C. Maintenance / Service When properly installed in accordance with applicable specifications, this device is mainte- nance-free. -
Page 6: 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 module. 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 7: Display Mode / Measured Value Display
The icon for the device status (see 6.2.3) is displayed in each operating mode. The contents of the header and the data area depend on the operating mode: Display of measured value Header: Icon description, if applicable. Otherwise "Value" ... - Page 8 The sequence of the screens with device data is as follows: Min-/Max values (pressure and sensor temperature) ----- Measured value (starting point) --- Pressure measurement (nominal range, damping, etc.) Current output (characteristic curve, limits, measuring range) ...

Page 10: 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 11 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.

Numeric values are entered digit by digit. First, always the leftmost digit is selected (visible with a triangle above and below the number). By pressing OK, you go to the next digit. parameter designation numeric value and unit Figure 6: Elements when setting a numeric value You change the selected digit by pressing the button. - Page 13 6.4.1 Main menue The main menue has the following entries: Menue entry Description Quick setup Selection of the most important settings Adjustment Adjustment functions for pressure measurement and current out- Display Functions for configuring the display Measurem./Output Configuration of the pressure measurement and current output Diagnosis Diagnostic information such as min/max values Simulation...

Correct zero point error due to installation position (not for absolute pressure devices) Lower adjust.
- Page 15 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.

With the menue item “Screen layout” you configure the information that is displayed and its layout. Up to four values can be displayed at the same time. In the additional menue entries "1st value"...
- Page 19 6.4.5.1 Setting the damping Using an adjustable damping you can eliminate fast pressure changes or peaks from having direct influence to the output signal. The set value in seconds corresponds to the time con- stant 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 20 6.4.5.4 Configuration of the table function With the table function you can realise any output function (display software version 1.1.0 and above). E.g. you can convert the fill height to the fill quantity depending on the tank shape. You can use up to 32 interpolation points for this purpose. Menue entry Description Number of points...
