Elevator positioning system USP 30 / 100
Final remarks for trouble shooting
Statistical exploitation of failure figures shows clearly that failures are rarely caused by the
USP sender or receiver.
Usually the sum of several bents in the signal wire will result in the fact that the signals cannot
be read correctly in the receiver. Even the most careful installation of the wire will occasionally
lead to problems of the wire. However, usually you do not need to change the wire as bends can
be removed manually in most cases.
Failures which cannot be re-produced are usually caused by external factors which influence the
electromagnetic compatibility.
