Why is my Milltronics Control Unit display blank?
If the display is blank and the transmit neon isn't flashing, and the transducer isn't pulsing, it's likely due to a power issue. Check the power supply, wiring, and voltage selection switch to ensure everything is correctly configured and functioning.
What does 'Open' and 'tb:(#)' mean on my Milltronics Control Unit?
If the Milltronics Control Unit displays 'Open' and 'tb:(#)', it indicates an open circuited transducer cable, or a defective transducer. Repair or replace as necessary.
What causes 'No response to programmer' in Milltronics Control Unit?
If there is no response to the programmer, it could be due to an obstructed infrared interface or a defective programmer. Clean the enclosure "docking bay" and programmer magnet slot.
What to do if Milltronics Control Unit reading fluctuates?
If the reading fluctuates while the material level is still (or vice versa), the measurement stabilization is incorrect. Alter the Measurement Response (P003) accordingly.
What to do if Milltronics Control Unit displays 'LOE'?
If the Milltronics Control Unit displays 'LOE', it indicates a weak or non-existent echo. Try to relocate and / or reaim the transducer at the material level or object.
Why does Milltronics Control Unit measurement accuracy improve as level nears transducer?
If measurement accuracy improves as the level nears the transducer, it indicates that the incorrect sound velocity is being used for distance calculation. Use an ultrasonic / temperature transducer or a TS-3 temperature sensor.
What to do if Milltronics Control Unit reading is fixed?
If the reading is fixed, regardless of the actual material level, the transducer beam may be obstructed, the standpipe is too narrow, or the transducer mounting is resonant. Relocate and / or reaim transducer at material level or object.
What to do if my Milltronics Control Unit always reports the material level 'off'?
If the material level reported is always 'off' by the same amount, the empty (zero) reference is incorrect. You should check Empty (P006), Reading Offset (P063), Offset Calibration (P650), & Offset Correction (P652).
What to do if Milltronics Control Unit displays 'EEEE'?
If the Milltronics Control Unit displays 'EEEE', it means the reading is too high. To resolve this, select larger units (P005) or lower the Convert Reading value (P061).
What to do if Milltronics Control Unit reading is erratic?
If the reading is erratic with little or no relation to the material level, the true echo may be too weak or the wrong echo is being processed. Try to relocate and / or reaim transducer at material level or object.
