SECTION 7 - MAINTENANCE
INTRODUCTION
The reliability of any stand-alone product or control system is
affected by the maintenance of the equipment. Bailey Controls
Company recommends that all equipment users practice a pre-
ventive 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 you in establishing good preventive
maintenance practices. Select the minimum steps required to
meet the cleaning needs of your system.
Personnel performing preventive maintenance should meet the
following qualifications.
•
Maintenance personnel should be qualified electrical tech-
nicians or engineers that know the proper use of test equip-
ment and how to handle electronic circuitry.
•
Maintenance personnel should know turbine shutdown
and start-up, and plant operating procedures.
