Additionally, a more detailed inspection has to be conducted.
• Whenever a machine setting is changed
• The local regulation or an application-specific standard requires an
inspection
• According to the inspection instruction and the risk assessment of the
application
• Frequently (for example, every six months)
A more detailed inspection must consider these actions:
• Machine stops or does not obstruct any safety function.
• The latest machine or connection modifications have no effect on the
control system.
• The outputs of the GuardShield safety light curtain are properly
connected to the machine.
• The total response time of the machine is shorter than the calculated value.
• Cables and plugs of the GuardShield safety light curtain are in flawless
condition.
• Mounting brackets, caps and cables are tightly secured.
• Optical windows and components (mirrors or weld shields) are clean.
IMPORTANT If one or more mirrors are used (see Mirrors on page 74
), inspect each
protective field separately. The movement of the test rod is also performed
directly in front of the mirrors.
IMPORTANT Document the test results, sign, and file them appropriately.
