6 • MAINTENANCE
This section gives the information and the necessary
warnings for routine maintenance of the controllers
and contains a Troubleshooting Guide which should
be read before seeking help from the Gefran
Customer Service Assistance, in the event of instru-
ment malfunction.
If installed and configured correctly according to the instruc-
tions and the recommendations provided in Sections 2 and 4
of these Instructions for use, the Controller will work normally
without any need for maintenance, apart from the usual ope-
rations of cleaning the faceplate, and if necessary the internal
parts of the instrument.
Cleaning the Controller
To clean the faceplate and the case use only a cloth
dampened in water or ethyl alcohol.
Do not use hydrocarbon-based solvents
(trichiorethylene, petrol, etc.).
Do not use compressed air to remove dust from the
electronic circuit boards, if necessary use a clean
brush with soft bristles.
Repairs
Repairs to the Controller must only be carried out by
qualified technicians, properly trained and authorized
by Gefran.
Any attempts at repair or modification of the Controller
hardware characteristics by unauthorized personnel
will invalidate the warranty.
