Chapter 2. Troubleshooting
The aim of this chapter is, in case a fault appears, to find the probable origin and to isolate any failed compo-
nent or sub-assembly; the required actions are then detailed.
For any inquiry to TR Chopin, please mention the serial number of the equipment.
1. Method ■
Possible failures are listed in:
- A. Error messages
- B. Other faults .
❏
Other abnormal events may occur: it is then up to the serviceman
to find the solution using analyses and comparisons. Simplified
interconnecting schematics are provided in section
3. of this chap-
ter, they may help to locate failures.
Of course, in case of difficulty or doubt, the engineering services of
CHOPIN Technologies are available to try to solve the problem, via
phone, fax or e-mail.
If this fails, the unit will have to be sent back to CHOPIN for work-
shop troubleshooting and repair.
■
Before starting any troubleshooting, all useful indications should
be recorded.
❏
In the event of abnormal results, a consultation of the results fol-
low-up log (control chart), if one exists, may provide an immediate
answer (case of continual drift for example).
❏
It is recommended to consult the settings audit trail in the menu
"Audit trail".
❏
Regardless of the failure, it is recommended to carefully record
the conditions under which the failure occurred.
If a failure occurred during a test, it is recommended to keep a
record of the curves and test results.
