• As a tripping device to initiate or reinitiate machine motion (PSDI applications), unless the machine and its control
system fully comply with the relevant standard or regulation (see OSHA 29CFR1910.217, ANSI/NFPA 79, ANSI
B11.19, ISO 12100, IEC 60204-1, IEC 61496-1, or other appropriate standard)
WARNING:
•
Proper Use
• Failure to follow all instructions and warnings could lead to serious bodily injury or death.
• Only use the SX Series Safety Laser Scanner on machinery that can be stopped immediately after
a stop signal is issued at any point in the machine's stroke or cycle. Under no circumstances may
the Scanner be used on full-revolution clutched machinery or in unsuitable applications as those
listed.
• Allow only Qualified Persons to install and maintain the SX Series Safety Laser Scanner. Perform
the Shift/Daily checkout procedure at every power-up, shift change, and machine setup. Refer to
the instruction manuals and other reference materials (located in the Help menu) for all installation
details, wiring diagrams, operating instructions, shift/daily/periodic checkout procedures, and
warnings.
• If there is any doubt about whether or not your machinery is compatible with the SX Series Safety
Laser Scanner, contact Banner's Application Engineers.
2.3.2 Control Reliability: Redundancy and Self-Checking
Redundancy requires that the
SX Series Safety Laser Scanner circuit components be backed up to the extent that, if the
failure of a single component will prevent effective machine stopping action when needed, that component must have a
redundant counterpart which will perform the same function. The SX Series Safety Laser Scanner is designed with redundant
microprocessors.
Maintain redundancy whenever the SX Series Safety Laser Scanner is in operation. Because a redundant system is no
longer redundant after a component has failed, the SX Series Safety Laser Scanner is designed to monitor itself
continuously. A component failure detected by or within the self-checking system sends a stop signal to the guarded machine
and puts the SX Series Safety Laser Scanner into a Lockout condition.
A recovery from this type of Lockout condition requires:
• Replacing the failed device (to restore redundancy, only performed by Banner Engineering Corp.)
• Performing the appropriate reset procedure
Use the Diagnostic Display to diagnose causes of a lockout condition. See Troubleshooting on p. 104.
2.3.3 Application Checklist
The SX Series Safety Laser Scanner can provide a protective function only when its settings and connections (software
configuration, Safety and Warning Zone dimensions, electrical interfacing, mounting, environmental conditions, supplemental
safeguarding, etc.) are coordinated with its application. The checklist items below and the following application examples are
intended to give additional guidance in applying the SX Series Safety Laser Scanner.
The following items are provided to assist in creating a checklist or to be included in a risk assessment for the application of
the SX. Additional items may be required, depending on the application.
• Review this instruction manual
• Identify the appropriate application (required resolution, field orientation, etc):
◦ Expert for horizontal applications
◦ Vertical for vertical applications
• Determine the area to be safeguarded and the SX's installation location and means.
• Determine whether the SX requires protection from mechanical damage.
• Ensure that the environmental conditions do not exceed the SX specifications.
• Determine the size and coverage of the Safety Zone and Warning Zone (if used) depending on:
◦ Physical location of the SX installation,
◦ The minimum safety distance or the stopping distance of the mobile vehicle
◦ The height (H) of the Protective Field (horizontal applications)
◦ Other factors that may require an increased minimum safety distance (e.g. "shadowing", adjacent SX, retro-
reflective surfaces, brake performance degradation)
•
Important: It is recommended to visibly mark the Protective/Warning Field boundaries, if possible.
• Assess the possibility of avoiding detection by the SX by climbing/stepping over, crawling under, moving around the
protection field(s), either at the perimeter of the fields or in unprotected areas caused by the shadow effect.
•
Determine whether additional/supplement safeguarding is required.
• Determine the proper startup, start/restart (manual/automatic reset), and other safety-relevant parameters. If the
manual restart is used, determine the position for the reset button.
