4.5 Testing plan
The manufacturer of the machine and the operating entity must define all required
c
hecks. The definition must be based on the application conditions and the risk assess‐
ment and must be documented in a traceable manner.
In addition, the device must be checked for correct functioning after each change to the
configuration and each insertion of the system plug.
►
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
Be
fore 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? (see "Checklist for initial
commissioning and commissioning", page 99)
•
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? (see
"Test rod check", page 37)
►
Define all guidelines for the check.
Regular thorough check
T
he 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?
°
Test rod check, page 37
°
Visual check of the machine and the protective device, page 40
•
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?
►
Define all guidelines for the check.
4.5.1 Test rod check
Overview
T
he 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.
