Reset Switch Location; Supplemental Safeguarding - Banner SX5 Instruction Manual

SX5 Safety Laser Scanner
WARNING: Use of the Banner device for Access or Perimeter Guarding
If a Banner device is installed in an application that results in a pass-through hazard (for example,
perimeter guarding), either the Banner device or the Machine Primary Control Elements (MPCEs) of the
guarded machine must cause a Latched response following an interruption of the defined area.
The reset of this Latched condition may only be achieved by actuating a reset switch that is separate
from the normal means of machine cycle initiation.
Lockout/Tagout procedures per ANSI Z244.1 may be required, or additional safeguarding, as described
by ANSI B11.19 safety requirements or other appropriate standards, must be used if a passthrough
hazard cannot be eliminated or reduced to an acceptable level of risk. Failure to follow these instructions
could result in serious injury or death.

3.7 Reset Switch Location

Mount the reset switch at a location that complies with the warning and guidelines below. If any hazardous areas are not in
view from the switch location, additional means of safeguarding must be provided. The switch should be protected from
accidental or unintended actuation (for example, through the use of rings or guards).
A key-actuated reset switch provides some operator or supervisory control, as the key can be removed from the switch and
taken into the guarded area. However, this does not prevent unauthorized or inadvertent resets due to spare keys in the
possession of others, or additional personnel entering the guarded area unnoticed. When considering where to locate the
reset switch, follow the guidelines below.
WARNING: Reset Switch Location
When considering where to locate the reset switch, you must follow the guidelines outlined in this
section.
If any areas within the guarded area are not visible from the reset switch, additional safeguarding must
be provided, as described by the ANSI B11.19 series or other appropriate standards.
Failure to follow these instructions could result in serious injury or death.
All reset switches must be:
• Outside the guarded area
• Located to allow the switch operator a full, unobstructed, view of the entire guarded area while the reset is
performed
• Out of reach from within the guarded area
• Protected against unauthorized or inadvertent operation (such as through the use of rings or guards).
Important: Resetting a safeguard must not initiate hazardous motion. Safe work procedures require a
start-up procedure to be followed and the individual performing the reset to verify that the entire
hazardous area is clear of all personnel before each reset of the safeguard is performed. If any area
cannot be observed from the reset switch location, additional supplemental safeguarding must be used:
at a minimum, visual and audible warnings of machine start-up.

3.8 Supplemental Safeguarding

Position the scanner components so an individual cannot reach through the defined area and access the hazard point
before the machine has stopped.
Additionally, the hazard cannot be accessible by reaching around, under, or over the defined area. To accomplish this,
install supplemental guarding (mechanical barriers, such as screens or bars), as described by ANSI B11 safety requirements
or other appropriate standards. Access must only be possible through the defined area of the Scanner or through other
safeguarding that prevents access to the hazard.
The mechanical barriers used for this purpose are typically called hard guarding; there must be no gaps between the hard
guarding and the defined area. Any openings in the hard guarding must comply with the safe opening requirements of ANSI
B11 or other appropriate standard.
