WARNING:
• The hazard must be accessible only through the sensing field
• Incorrect system installation could result in serious injury or death.
•
The installation of the EZ-SCREEN LPM must prevent any individual from reaching around,
under, over or through the defined area and into the hazard without being detected.
• See OSHA CFR 1910.217, ANSI B11.19, and/or ISO 14119, ISO 14120 and ISO 13857 for
information on determining safety distances and safe opening sizes for your guarding device.
Mechanical barriers (for example, hard (fixed) guarding) or supplemental safeguarding might be
required to comply with these requirements.
5.2 Other Considerations
5.2.1 Reset Switch Location
The reset switch must be mounted 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:
• Install reset switches properly
•
Failure to properly install reset switches could result in serious injury or death.
• Install reset switches so that they are accessible only from outside, and in full view of, the
safeguarded space. Reset switches cannot be accessible from within the safeguarded space.
Protect reset switches against unauthorized or inadvertent operation (for example, through the
use of rings or guards). If there are any hazardous areas that are not visible from the reset
switches, provide additional safeguarding.
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.
5.2.2 Adjacent Reflective Surfaces
WARNING:
• Do not install the system near reflective surfaces
• Reflective
surfaces could reflect the sensing beam(s) around an object or person within the
defined area, preventing detection by the system. Failure to prevent reflection problems results in
incomplete guarding and an optical short circuit that could result in serious injury or death.
• Do not locate the defined area near a reflective surface. Perform the trip test, as described in the
product documentation, to detect such reflection(s).
A
reflective surface located adjacent to the defined area may deflect one or more beams around an object in the defined
area. In the worst case, an optical short circuit may occur, allowing an object to pass undetected through the defined area.
