7 Trouble shooting
Errors / malfunctioning is indicated by the indicator LED’s or the display.
Error by indicator LED
Indicator LED’s are normally green or switched off. A red or orange indicator LED means normally
there is something not ok. See Appendix D for the explanation of the different colors.
Errors indicated at menu option “dE”
In menu option “dE” it is possible to see actual error codes. When entering the display menu option
“dE” the errors code will be shown and the error will be cleared. If the error is not cleared it means
there is still an error. There can be more than one error. Further errors are displayed one after another
with a short delay between each code.

Identification performance and disturbance
Identification performance can be reduced by disturbance caused by variable-frequency drives used
for ventilation, milk pumps, vacuum pumps, etc. Also ballasts used for fluorescent tube lighting may
interfere. If there is interference one can locate the source by switching off all the equipment on a farm
and then switch them on again one by one. Most of the time when a variable-frequency drive is
causing a problem it is due to bad installation or without the mandatory main filters.
