INSTALLATION
26
SAFERY LASER SCANNER
• Power off the safety laser scanner(s). Check that both OSSD outputs automatically
switch to OFF status and make sure that the machine cannot start until power is
re-applied.
• If the check session reveals hypothetical faults, the machine must be shut down
immediately to allow further checks on the electrical and mechanical installations
by qualified personnel.
• The risk evaluation of the machine may determine that further or more frequent
checks are required depending on the application conditions.
• Together with the regular checks, it is recommended to perform a visual check of
the machine and the safety device.
• The machine builder must check the display and the status LED: if a machine is
switched ON, and at least one LED below the safety laser scanner’s display is not
functioning properly, it may be a failure.
• Test the device by triggering the safety function, e.g. the machine builder can
observe the reaction of the OSSDs.
• For all device applications: check if the Laser Sentinel shows the interruption of
the safety field using the LEDs and/or the display.
• Horizontal application: stop the safety field using an appropriate test piece and
check if the machine stops.
• Activate a protective field, which is interrupted by at least one test piece and
check the expected reaction.
• If the check reveals a fault, the machine must be shut down immediately. In this
case, the mounting and electrical installation of the safety laser scanner must be
checked by qualified personnel.
• In case of Manual Restart, the Restart button must be placed outside the danger-
ous area. The operator must have full view of the dangerous area to activate the
Restart button.
