Section 5
Maintenance
Introduction
This section contains a preventive maintenance schedule for
the power system (Table
5-1 ). This table has a procedure refer-
ence 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. All equipment users
should 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
preventive maintenance procedures should be used as a
guideline to assist in establishing good preventive mainte-
nance practices. Select the minimum steps required to meet
the needs of the 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
equipment.
•
Maintenance personnel should be familiar with the equip-
ment, have experience working with process control sys-
tems, and know what precautions to take when working
with live AC power.
