Section 5
Maintenance
Introduction
This section contains a preventive maintenance schedule for
the Conductor VMS Series 43 Auxiliary Terminal (Table
5-1 ).
This table has a procedure reference next to the task when
applicable. The reference indicates the procedure number
where the procedure for that task can be found.
Be sure to follow all warnings, cautions and notes. Put boards
containing semiconductors into antistatic bags when stored or
shipped back to the factory. Do not repair printed circuit
boards in the field. All repairs and adjustments should be per-
formed by qualified personnel.
The maintenance of any stand-alone product or control system
affects the reliability of that product. Elsag Bailey recommends
that all equipment users practice a preventive maintenance
program that will keep the equipment operating at an optimum
level.
The procedures referred to in this section contain instructions
that the customer should be able to perform on site. These pre-
ventive maintenance procedures should be used as a guideline
to assist in establishing good preventive maintenance prac-
tices. Select the minimum steps required to meet the 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 work-
station, have experience working with process control sys-
tems, and know what precautions to take when working
with live AC power.
