SECTION 6 - MAINTENANCE
INTRODUCTION
The reliability of any stand-alone product or control system is
affected by the maintenance of the equipment. Elsag Bailey
recommends that all equipment users practice a preventive
maintenance program that will keep the equipment operating
at an optimum level.
This section presents procedures that can be performed
on-site. These preventive maintenance procedures should be
used as guidelines to assist in establishing good preventive
maintenance practices. Select the minimum steps required to
meet the needs of your system.
Personnel performing preventive maintenance should meet the
following qualifications.
•
Should be qualified electrical technicians or engineers that
know the proper use of test equipment.
•
Should be familiar with the IMFEC1
module and the
INFI 90 OPEN system, have experience working with pro-
cess control systems, and know what precautions to take
when working on live AC systems.
