8.2 General Description and Hints
8.2.4 Keep Track of History
Make a Historical Error
Log
In some cases, a particular installation may give rise to faults not encountered in
others. Therefore, a log of each installation may give valuable assistance to the
trouble shooter.
To facilitate trouble shooting, a log of the circumstances surrounding the fault gives
the following advantages:
• It enables the trouble shooter to see patterns in causes and consequences not
apparent at each individual fault occurrence.
• It may point out a specific event always taking place just before the fault, for
example a certain part of the work cycle being run.
• When an error occurs, keep track of the last operations done by the robot.
Check Up the History Make sure you always consult the historical log if it is used. Also remember to
consult the person who was observing the problem.
At What Stage did the
Fault Occur
What to look for during trouble shooting depends greatly on when the fault
occurred: Was the robot just freshly installed? Was it recently repaired?
