Why is my Hawk Sultan unit measuring incorrect depth or height?
- S
  stephenjacksonAug 9, 2025
  If your Hawk Sonar unit is measuring incorrect depth or height, it could be due to several reasons. First, confirm that the display mode is correct; depth is measured from the sensor face to the target, while height is measured from the low level to the target. Also, confirm that the High Level and Low Level settings match your application requirements. You might also need to adjust the selected 'Density'. A higher density value programs the unit to look for a more dense layer deeper. High volumes of poorly settling or suspended material can cause the unit to read higher by tracking suspended material if process conditions in the tank fail.

How to troubleshoot Hawk Sultan amplifier when it cannot communicate with the transducer?
- E
  Erik OwensAug 14, 2025
  If your Hawk Sonar amplifier or transmitter cannot communicate with the transducer, consider the following troubleshooting steps: * Check the terminals for a loose or incorrect wiring connection, including the junction box and cable extensions. * Inspect the cables for any signs of damage. * Ensure that any customer-supplied cable meets Hawk specifications. If you're using a junction box extension, trace the 8-10VDC from the red/black amplifier terminals to the transducer to ensure the wires are correctly connected. Also, if using a junction box, ensure you follow Hawk specifications for extending the cable.

What to do if Hawk Sonar shows voltage error?
- K
  Kelly IbarraAug 19, 2025
  If your Hawk Sonar shows a voltage error, and you are using AC power, check the power supply for faults by reading the DC +/- terminals; they should show a stable 16VDC. If the value is lower or inconsistent, there may be a problem with the internal power supply. If the unit detects voltage below 9VDC, performance will be affected. If ‘V in chk’ is on, the unit will trigger its failsafe routine; if ‘V in chk’ is off, the unit will display ‘V fail’ on the LCD. This can be caused by the unit detecting voltage below 9VDC.

What causes 'Transducer no. 2 communication error' on Hawk Sonar?
- R
  Roger BrennanAug 25, 2025
  A 'Transducer no. 2 communication error' on your Hawk Sonar can be caused by wiring issues or a problem with the transducer itself. If any circuits are open, check the wiring connections. Transducer problems may cause the amplifier to protect itself against high current draw. Measure the resistance across the transducer: Red and DC:+ terminals on the amplifier while the transducer is disconnected and then connected. If the resistance increases dramatically, there is potentially a wiring or transducer problem.

What to do if Hawk Measuring Instruments display higher distance than actual level?
- C
  Carl MendozaAug 29, 2025
  If your Hawk Measuring Instruments display a distance higher than the actual level, begin by checking the mounting conditions within the vessel and inspecting the distance of any false echoes. Also, consider extending the ‘Blanking’ distance in the TX Setup to eliminate the echo entirely.
