CHECKS AFTER FIRST INSTALLATION
After the initial installation and before starting up, machine test operations must be car-
ried out by qualified personnel, or under the strict supervision of the person in charge
of the machine
safety.
The checks to carry out are listed below:
• The response time at machine STOP, including the ESPE and machine response
times, mus
t be included in the limits defined in the calculation of the safety dis-
tance (refer to "
Response Time and Scan Cycle Setting" on page 62).
• The safety distance between the dangerous parts and ESPE must comply with the
r
equirements indicated in "
Device Positioning and Minimum Distance Calculations"
on page 15. The safety zone must be designed so that the approach towards any
dangerous point of the machine can be possible only passing through it, and the
dis
tance that a person is obliged to cover must be longer than the minimum safety
distance.
• A person must not remain between safety zone and dangerous parts of the
mach
ine undetected.
• Access to the dangerous areas of the machine mus
t not be possible from any
unprotected area.
• Verify the correspondence of all the accessory functions, activ
ating them in the
different operating conditions.
• The machine builder must define the type and frequency for the checks of the
mach
ine and its safety system based on the risk assessment. Regular checks are
recommended in order to prevent external influences or modification (such as
damage or tampering).
• Safety checks must be carried out at least annually by qualified personnel only and
mus
t be documented in a traceable manner.
• To test the detection capability of the device(s),
the user can use a suitable test
piece, e.g. an optically dark, opaque cylinder. The effective diameter should match
the configured resolution. Datalogic suggests adopting the following procedure:
Place the test piece on several points at the edges of the safety area. The safety
laser sc
anner must detect the test piece at each position and go to STOP. The num-
ber and location of sites where the test is performed must be chosen so that
undet
ected access to the hazardous area is not possible.
Do not attempt to insert the test piece into dangerous parts of the machine
loc
ated in the safety area.
Remove the test piece from the controlled area and check that:
-the machine automatically restarts (in case of Automatic restart), OR
-the machine restarts only after receiving the restart command (in case of Manual
re
start).
The following pictures are examples of detection capability test (the red areas cor-
respond to the configured Safety Areas).
