AQ Elteknik D72 User Manual

AQ Elteknik AB Ultrasound Controller Manual 35
the menu system of DP72. Calibration takes about 1-5 seconds and during this time DP72 will not
accept any new calibration commands (calibration in progress is shown in response data 1 bit7).
Response Data
Most of the Response data is the same data as shown in SHOW DATA menu and the start
screen. The format is 8 bit unsigned and in some cases 16 bit unsigned. Chapter SHOW DATA
gives more information about the data.
Air Sensor: Response data 1 and 2 bit 0 shows the Filtered Air/Liquid-data for the selected
sensitivity. Filtered Air/Liquid-data for all sensitivities are available in Response data 3 and 4 and
can be used to show different bubble sizes or change sensitivity without changing any settings.
The indication of Air is always minimum 0,5s even if a bubble passes quickly through the Air
Sensor.
Level Sensor: For Measured Level %, the value 255 corresponds to 100%. For Measured Level mm
the format is 16 bit unsigned data: high byte and low byte

TROUBLESHOOTING
The Profibus status-symbol on the start screen at the bottom right corner of the display gives
information for troubleshooting. When Profibus is working correctly, Profibus status-symbol should
show alternating > < (indicating data communication).
If the Profibus status-symbol shows □ it means there is no kind of communication detected. The
reason can be Profibus-cable is not connected or Profibus Master is inactive.
If the Profibus status-symbol shows or blinks █ it means there is communication but it cannot be
interpreted. Bitrate or cable polarity can be wrong.
If the Profibus status-symbol shows T it means Profibus-telegram is detected but the master is not
sending parameters. The reason can be wrong address or the master is missing the gsd-file.
If the Profibus status-symbol shows P continuously it means the Profibus master repeatedly
sends parameter telegrams but DP72 do not accept them. Something is wrong with the parameter
telegrams. The reason can be the master has wrong gsd-file or wrong gsd-file version.
If no Profibus status-symbol is shown at all it means Profibus is not enabled.
