Maintenance Inspections

 

 

 

 

 

 

 

 

 

In order that your SYSMAC system operates 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. Environmental conditions, how-

 

 

 

 

ever, can lead to electrical element deterioration, making regular maintenance

 

 

 

 

necessary.

 

 

 

 

 

 

 

 

 

The standard period for maintenance checks is 6 months to 1 year, but depend-

 

 

 

 

ing on the environment checks may need to be more regular.

 

 

 

 

If the criteria are not met, adjust to within the specified ranges.
