IMPROPER SAFETY DISTANCE
•
Calculate safety distance using formula Ds =K x (Ts + Tc + Tr) + Dpf (see explanations above)
•
Ds is the minimum safety distance from the light curtain sensing field to the danger zone
(OSHA 29 CFR 1910.217 (c) (3) (iii) (e) and ANSI B11.1, B11.2, B11.19, and R15.06)
•
The Depth penetration factor Dpf is determined by both the installation of the product as well as the product’s resolution
(Minimum Object Sensitivity).
Failure to comply with these instructions could result in death or serious injury.
IMPROPER PROTECTIVE HEIGHT
•
For ‘Reach Thru” applications, the light curtain’s protective field must be sufficiently great such that personnel can not reach
over or under the light curtain without being detected.
•
The protective height is determined by the installation, measuring from the reference floor to the top beam.
•
A protective height of 48 in may be adequate to detect personnel reaching through the curtain light field.
Reference ANSI
R15.06 Annex B – supplemental information
•
The installation may require a protective height greater than 48 in to properly safeguard personnel due to their height or
working position (standing or sitting) or work station position relative to variations in floor elevations (or work platforms or
stairs).
•
Before use, verify that the protective heights are adequate for their intended use of safeguarding personnel.
Failure to comply with these instructions could result in death or serious injury.
IMPROPER USE OF FF-SYA234 multibeam systems
Do not use the FF-SYA234 multibeam systems in parallel or angled approach applications. Use the FF-SYA234 only in normal
approach applications.
Failure to comply with these instructions could result in death or serious injury.
NON COMPLIANCE TO ANSI/RIA 15.06–1999 WITH FF-SYA02500
Only the three beam (FF-SYA03400 Series) and the four beam versions (FF-SYA04300 series) are in compliance with the beam
heights, specified in the US Standard ANSI/RIA R15.06-1999 (Industrial Robots and Robot Systems – Safety Requirements).
The two beam version (FF-SYA02500 Series) does NOT comply with ANSI/RIA R15.06 and may require additional protection.
Refer to applicable standards. In the absence of an applicable standard, ANSI B11.19 and ANSI R15.06 may be used as
reference for the USA, as well as EN 999 (or the relevant European Type C machine standard) for Europe.
