once for normal status, if it does not blink or blinks only once in a long time, it indicates that there 

is a communication fault. 

Units: Indicates the system distance measurement units. 

Current value: Indicates the theoretical 4-20mA current output value corresponding to the 

analogue quantity to be measured, which is obtained by converting the system according to the 

[high  and  low  adjustment  points]  and  4-20mA  [current  output  function],  see  sub-section  6.5.4. 

(6-8) for the specific conversion relationship. 

Fault codes: Please see Fault Analysis and Troubleshooting for specific meanings.

Return strength: The number indicates the maximum return strength within the range. With 

a good metal reflector, the return strength should be around 90dB, if the return strength is less 

than  30dB,  it  indicates  a  weak  return  signal  and  requires  the  technician  to  carry  out  the 

corresponding troubleshooting. 

Real time value: The real time and damping values of the echo interface are not affected by 

the  [Sensor  type]  setting  and  always  give  distance  information,  pointing  to  the  selected  echo 

wave crest. 

Echo  strength  unit:  indicates  the  signal  strength  of  the  echo  currently  selected  by  the 

algorithm. Due to the noise floor rising near the end of the FMCW itself, the echo strength and 

echo strength units are not necessarily the same.
