SYSMAC LINK Units must be inspected on a regular basis to ensure correct
operation. SYSMAC LINK Units are built primarily of solid-state components
and contain almost no parts subject to wear. Nevertheless, the life span of
some solid-state components can be shortened as a result of adverse envi-
ronmental conditions.
We recommend that the following points be checked at least once every 6 to
12 months as part of a standard inspection program. Ambient conditions
should be checked more frequently. If any of these items deviate from the pre-
scribed standards, take appropriate action to correct the condition.
Inspection contents
Check the ambient tempera-
ture and the temperature
inside the unit.
Check the ambient humidity
and the humidity inside the
unit.
Check there is no dust.
Check the SYSMAC LINK
Unit is firmly fixed.
Check the cable connectors
have been fully inserted.
Check that external wiring
screws are not loose.
Check that external wiring
cables are not frayed.
We recommend that users have backup Units available to make repairs and
minimize down-time if a problem occurs in a SYSMAC LINK Unit.
Please observe the following precautions in the event of a problem:
• Always turn OFF the power when replacing a SYSMAC LINK Unit.
• If a SYSMAC LINK Unit fails, replace it with a new one and immediately
verify that the new Unit is working properly.
• When returning a malfunctioning SYSMAC LINK Unit for repair, please
attach a detailed description of the problem to the Unit and return it to the
sales office nearest you (see listing at the end of this manual).
• If you suspect that a poor connection is the cause of a malfunction, clean
the connectors using a clean, soft cloth and industrial-grade alcohol.
Remove any lint or threads left from the cloth, and re-mount the SYSMAC
LINK Unit.
The following tools and equipment will be needed to perform inspection and
adjustments.
• Assorted flat-blade and Phillips screwdrivers
• Circuit tester or digital voltmeter
• Industrial-grade alcohol and clean cotton cloth
• Synchroscope
• Pen-chart recording oscilloscope
• Thermometer, hygrometer
