    Assembly and disassembly To connect sensor wires to the 7501 or change the orientation of the display, the housing must be disassembled and the internal device must be extracted. !! Disconnect power to the device before disassembly. Locking screw 1. Release the locking screw, using a hex spanner with a cross-flat of 2 [mm]. This screw is situated on the housing top.
  • Page 16 4. While holding the clamps, pull the display unit outwards to remove it. 5. The display can now be turned in steps of 90 degrees for best viewing angle. 6. For easy connection of sensor wires, we recommend extracting the transmitter from the housing (see the section Connections for information on connecting sensors to the internal 5337).
  • Page 17 9. Use a screwdriver (or your fingers) to lever the taps (one on each side) on the fixation bracket to release it from the transmitter connector bracket. NB! Do not use excessive force. 10. Separate the connector bracket, transmitter and fixation bracket. 7501V107-UK...

These diagnostics can be divided into 4 categories: Sensor status, sensor errors, device status and device errors. Sensor status Sensor 1 exceeds upper sensor limit IN.HI...

  • Page 25: Display Menu

    The menu can be temporarily locked because it is receiving a configuration on the HART interface or because it is synchronizing configuration parameters with the internal device. If the 7501 has been write-protected it is still possible to proceed to the menu, but no changes can be made, and it is not possible to save the configuration.

  • Page 29: Calibration

    Calibration (only if Write-protection is disabled) The device can be process-calibrated in two points to fit a given input signal. A low input signal (not necessarily 0%) is applied and the actual value is entered. Secondly a high input signal (not necessarily 100%) is applied and the actual value is entered. If you accept to use the calibration (by selecting Yes in the Save menu) the device will work according to the new adjustments.

  • Page 30: Simulation

    (only if Write-protection is disabled) The 7501 allows you to simulate process values by entering the simulation menu. Using the  and 2 optical buttons, the simulated value can be increased and decreased (see the section Operating the optical buttons). Please note that while performing a calibration the display will not time out.

  • Page 31: Sensor

    Sensor The sensor menu allows you to make more detailed configuration of your sensor values, which are not available in the basic configuration menu. These involve selecting from a large amount of process variable units, changing the sensor assignment to PV, SV, TV and QV and specifying the CJC response time.
