Maintenance Inspections
In order for your SYSMAC system to operate in optimum condition, be sure to
carry out daily or periodical inspections.
Inspection Items
The main system components of a SYSMAC system are semiconductors, and
it contains few components with limited lifetimes. Poor environmental condi-
tions, however, can lead to deterioration of the electrical components, making
regular maintenance necessary.
The standard period for maintenance checks is 6 months to 1 year, but more
frequent checks are required if the PC is operated in more demanding condi-
tions.
If the criteria are not met, adjust to within the specified ranges.
