Section 9
Maintenance
Introduction
The reliability of any stand-alone product or control system is
affected by the maintenance of the equipment. ABB Automa-
tion recommends that all equipment users practice a preven-
tive 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 cleaning needs of your system.
Personnel responsible for maintenance should be familiar with
the Harmony I/O system, have experience working with pro-
cess control systems, and know what precautions to take
when working on live AC systems.

Table 9-1 is the preventive maintenance schedule for the Har-
mony I/O system. The table lists the preventive maintenance

val. Some tasks in Table

ered in the indicated procedure section.
