  • Page 2: General Information

    In addition to this instruction, be sure to observe all statutory requirements, applicable 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: Electrical Connection

    Pressure transmitter and diaphragm seal are a closed system that must not be separated. You can find further information about diaphragm seals in the document TA_031 on www.labom.com. Mounting the Remote Display Optionally you can mount the display and control unit up to 10 m away from the measuring point in an additional housing.
  • Page 4 30 – 64 mm. For pipe mounting, you can order the corresponding U-bolts from LABOM. For best EMC protection, only use the included cable. If you ordered the remote display together with the device, the assembly has been completed in the factory.

No other monitoring is necessary. Permissibe ambient temperature: -40…80 °C Test Terminals You can check the output current without interrupting the current loop, using the test terminals on the terminal board.

    Warning Opening pressurized lines might cause severe injuries. Danger of severy injuries or damage  Relieve the process pressure before attempting to remove the device. Shut off the pressure supply for all feed lines to the device and relieve the pressure in them.

  • Page 8: Display Mode / Measured Value Display

    The structure of the display is the same in every operating mode. The display area is divided into four zones:  Header  Icon indicating device status  Data area  Bar graph related to the currently measured value Header Icon Data area Bar graph of...
  • Page 9 6.2.1 Quick Access to Device Data You can access a number of device parameters directly from the measured value display using the -buttons. This allows a quick overview of the device configuration. With the -button you can display variable data (trailing pointers and counters), with the -button static information such as configuration data.
  • Page 10 The list of icons is sorted in descending priority. Only the icon with the highest priority is shown. The two most important icons for fault and/or warning are flashing when displayed. 6.2.3 Display layouts You can configure the layout of the measured value display as well as the displayed information individually.

  • Page 11: 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 menus by using the arrow buttons. The selected menue item is indicated by triangles on the left and right.
  • Page 12 6.3.1 Selection of a value from a selection list When opening a selection list, the currently set value is shown above the selection list. Up to three entries are shown at the same time. When the selection list is longer, a scroll bar on the left side of the display indicates the position of the selected item in the selection list.

  • Page 18 Please note that units can only be selected for nominal ranges that the device can display. For instance, the unit Pascal is hidden for nominal ranges above 1 bar. The unit selection in this submenue only affects the display on the screen. Communication via HART is performed using the unit set in the HART driver.
  • Page 19 6.4.5.2 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 constant of an exponential rise. After a suddon pressure change, it takes the damping time to reach 63.2% of the actual pressure at the output.
  • Page 20 6.4.6 "Current Output" menue In the "Current Output" menue, you configure all aspects of the current loop. Menue entry Description Output function Setting the output function (linear, inverse, square root, table) Table Specifying the interpolation points for the table function Alarm current Selection of the alarm current: High (>21 mA) or low (<3.6 mA) Lower current limit...
  • Page 21 long long Figure 16: Changing a table point 6.4.6.2 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 pressure does not change the current. You can freely select these current limits for the lower limit between 3.8 and 4 mA and for the upper limit between 20 and 21 mA.
  • Page 22 Figure 17: Display and resetting of the trailing pointer for pressure 6.4.7.2 The maintenance timer Using the maintenance timer, the device can signal the need for maintenance after a freely selectable number of operating hours. The timer counts down from the start value. Maintenance need is indicated by an icon in the display (see 6.2.2) and, if necessary, the HART protocol.
