Honeywell SYA14 Series Manual page 547

•
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-SRM muting module combined with a Honeywell safety
ligth curtain must comply with the following applicable American standards :
US Standards Title
ANSI B11.1 Mechanical Power Presses
ANSI B11.2 Hydraulic Power Presses
ANSI B11.19 Safeguarding when Referenced by the Other B11
Machine Tool Safety Standards
ANSI/RIA R15.06 Safety Requirements for Industrial Robots and Robot
Systems
1.11 Additional Protection
The FF-SRM module needs a number of auxiliary sensors to initiate and interrupt a muting
sequence in safe conditions. The installation of these sensors and the installation of the
safety light curtain must be done in accordance with the FF-SRM module specifications,
and additional mechanical guarding must be used as follows:
- auxiliary sensors must be installed in such a way that a muting sequence cannot be
started by a person.
- the additional mechanical guardings must be designed and installed in such a way that
people cannot enter the dangerous area without being detected by the safety light curtain
and the auxiliary sensors, if relevant. In particular, a person following parts vehiculed
towards the dangerous zone must be detected when interrupting the safety light curtain
detection field. The design and the installation of these additional mechanical guardings
must comply with the requirements of the below mentioned European standards.
Moreover, 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.
