2. Fault Diagnosis
2.1 Procedure for fault-finding
To locate and rectify a fault that has arisen in a TNC in-
stallation,
it is of foremost
importance to analyse
the be-
haviour of the system as a whole: that is, the TNC Control,
the machine-tool and the measuring system.
2.2.1 shows,
in flow diagram form, the procedure for exam-
ining the complete installation.
In addition, the HEIDENWGN TNC 151/155 Contouring ContrOl
includes an extensive integrated supervision system for the
avoidance of entry/operator faults and for the recognition
and diagnosis of technical defects in the installation
(see section 2.2.2)
The Burn-In Test Program can be used as further support in
fault localizing and in the dynamic testing of the Control's
hardware (see section 2.2.6).
