Appendix C: Troubleshooting

Measurement Difficulties

If the Failsafe Timer (P070) expires due to a measurement difficulty, LOE flashes

alternately with the last known Reading. In rare cases, the MultiRanger may lock on to a

false echo and report a fixed or wrong reading.

Flashing LOE Display

The loss of echo (LOE) display appears when the echo confidence is below the threshold

value set in P805 Echo Confidence.

LOE occurs when:

• The echo is lost and no echo is shown above the ambient noise. See low echo

confidence (P805) and low echo strength (P806).

• Two echoes are too similar to differentiate. See low echo confidence (P805) and low

echo strength (P806).

If LOE is displayed, check the following:

• Surface monitored is within the transducer maximum range

• Transducer model (P004) matches the transducer used

• Transducer is located and aimed properly

• Transducer is not submerged without a submergence shield

Adjust Transducer Aiming

See the transducer manual for range, mounting, and aiming details. For optimum

performance, adjust transducer aiming to provide the best Echo Confidence (P805) and

Echo Strength (P806) for all material levels within the measurement range.

The most efficient method of checking echoes is with Siemens Milltronics Dolphin Plus

software.

Displaying Echoes

Use Dolphin Plus to graphically display

the echo profile at the installation.

Interpret the echo profile and change

relevant parameters.
