b
When defining the check, please note the following:
°
Define the type and execution of the check.
°
Define the frequency of the check.
°
Notify the machine operators of the check and instruct them accordingly.
The following checks are often defined in connection with a protective device:
•
Check during commissioning and modifications
•
Regular thorough check
Check during commissioning and modifications
Before commissioning the machine and after making changes, you must check whether
the safety functions are fulfilling their planned purpose and whether persons are being
adequately protected.
The following points are often helpful for the definition of the check:
•
Does the check have to be completed by qualified safety personnel?
•
Can the check be completed by specially qualified and authorized personnel?
•
Does the check have to be documented in a traceable manner?
•
Can the check be carried out according to a check list? (
commissioning and commissioning", page 73
•
Do the machine operators know the function of the protective device?
•
Have the machine operators been trained to work on the machine?
•
Have the machine operators been notified about modifications on the machine?
•
Does the hazardous area being secured have to be checked with a test rod? (
)
b
Define all guidelines for the check.
Regular thorough check
The thorough check is intended to ensure that the safety functions are fulfilling their
planned purpose and whether persons are being adequately protected.
The following points are often helpful for the definition of the check:
•
Which check must be carried out and how is it carried out?
°
,
°
Visual check of the machine and the protective device
,
•
How often does the check have to be carried out?
•
Do the machine operators have to be notified of the check and do they need to be
instructed accordingly?
b
Define all guidelines for the check.
4.5.1
Test rod check
Overview
The rod test check is used to check whether the hazardous point is only accessible via
the protective field of the safety light curtain and whether the protective device is able
to identify each time the hazardous point is approached.
The test is carried out with an opaque test rod whose diameter corresponds to the
resolution of the safety light curtain.
