SECTION 6 - 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.

•

Maintenance personnel should be familiar with the DSO
module, have experience working with process control sys-
tems, and know what precautions to take when working on
live electrical systems.

PREVENTIVE MAINTENANCE SCHEDULE

Table

is the preventive maintenance schedule for the DSO

module. The table lists the preventive maintenance tasks in
groups according to their specified maintenance interval. Some
tasks in Table

are self explanatory. Instruction for tasks

that require further explanation are covered under

TIVE MAINTENANCE PROCEDURES

NOTE: The preventive maintenance schedule is for general pur-
poses only. Your application may require special attention.

WARNING

Wear eye protection whenever working with cleaning solvents.
When removing solvents from printed circuit boards using
compressed air, injury to the eyes could result from splashing
solvent as it is removed from the printed circuit board.

AVERTISSEMENT

Des lunettes de protection devraient être portées lors de travail
avec des solvants nettoyants. Lorsqu’on enlève les solvants
des circuits imprimés à l’aide d’air comprimé, les éclabous-
sures de solvant pourraient causer des blessures aux yeux.
