5-6 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 conditions,
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 fre-
quent checks are required if the PC is operated in more demanding conditions.
If the criteria are not met, adjust to within the specified ranges.
Inspection items Details Criteria Remarks
Power supply Determine whether the voltage fluctuation
at the power supply terminals is within
specifications.
Within the voltage variation
range (see note)
Tester
Environmental
conditions
Is the ambient temperature inside the
panel appropriate?
0 to 55_C
Thermometer
Is the ambient humidity inside the panel
appropriate?
10% to 85% RH with no
condensation
Hygrometer
Has dirt or dust collected? None Visual inspection
I/O power supply Is the voltage fluctuation measured at the
I/O terminals within the standard range?
Each I/O terminal must
conform to the specifications
