3.7.3 Troubleshooting
For troubleshooting it is necessary that the maintenance crew has a profound knowledge of the
leak detection system.
Possible errors can be divided in internal and external. Internal errors are declared as occurring
in the leak detection software program, e.g. an incorrect parameter setting. External errors are
failures outside the LDS operator or monitoring station, e.g. a failure in the data communication
system.
