1.9 United States Regulations Compliance
US Regulation
OSHA 29 CFR 1910.212
OSHA 29 CFR 1910.217
•
Safety light curtains may be used as primary protection for machines where the movement of the functional parts can be
interrupted at any moment in a dangerous phase.
•
Safety light curtains may be used as primary protection for machines on which the control circuit has been designed in
such a manner that a fault in one component does not result in any risk.
•
Cancellation of the safety light curtain stop signal must not cause the restart of the moving parts. The function to restart
can only be initiated by means of a control designed for this purpose.
1.10 United States Standards Compliance
Installation and use of the FF-SYA light curtain must comply with the following applicable American standards (non-exhaustive
list):
Standards
ANSI B11.1
ANSI B11.2
ANSI B11.19
ANSI/RIA R15.06 - 1999
1.11 Additional Protection
In some applications, it may be necessary to provide additional protection to maintain the protection level provided by the
safety light curtain. Hard guards or additional presence sensing devices such as safety mats or laser scanner, may be used to
ensure the operator is either forced to move through the sensing field to enter the danger zone, or forced to stand on the
sensing area inside the danger zone.
Hard guards should be installed permanently with the aid of a tool or welded (if possible). If hard guards need to be
automatically positioned, their positioning must be checked. It must not be possible for operators to neutralise the detectors
associated with these hard guards. Hard guards shall comply with the following applicable European Standards:

Honeywell FF-SR Series safety control modules may be used as an interface between protective safety equipment and
machine control circuitry. The following safety control modules are particularly recommended:
•
FF-SRS: safety control module designed for emergency stop
•
FF-SRD Series: safety control module designed for door monitoring
•
FF-SR2: safety relay control module designed for two-hand controls
•
FF-SR0 Series: safety control module designed for standstill detection on inductive motors
•
FF-SRT Series: time delay module
•
FF-SRE Series: extension relay module
•
They offer redundancy, monitoring, and control reliability features that ensure the highest level of industrial safety.
Honeywell safety switches and sensors that may be used to check the position of guards include:
•
GSS safety limit switches
•
GK and GKM key operated safety switches
•
GKR/L solenoid key operated safety interlock switches
•
24/924CE miniature safety limit switch
Honeywell safety optoelectronic products that may be used with the FF-SYA Series safety light curtain include:
•
FF-SM safety mat
•
FF-SE laser scanner
•
FF-SPS4 single beam safety device
•
