WARNING: The Hazard Must Be Accessible Only through the Sensing Field
The installation of the SX5 must prevent any individual from reaching around, under, over or through the
sensing field and into the hazard without being detected. Mechanical barriers (for example, hard (fixed)
guarding) or supplemental safeguarding may be required to comply with this requirement, and is
described by ANSI B11.19 safety requirements or other appropriate standards. Failure to follow these
instructions could result in serious injury or death.

Figure 27. Supplemental safeguarding inside a robotic work cell
This shows an example of supplemental safeguarding inside a robotic work cell. The safety light screen, in conjunction with
the hard guarding, is the primary safeguard. Supplemental safeguarding (such as scanners used as area guards) is required
in areas that cannot be viewed from the reset switch (for example, behind the robot and the conveyor). Additional
supplemental safeguarding may be required to prevent clearance or trapping hazards (e.g., the safety mat as an area guard
between the robot, the turntable, and the conveyor).
3.9 Mobile Applications
The SX5 can protect individuals entering an area with a variable or moving hazard, protect individuals and objects located
within a mobile vehicle’s path, and protect the mobile vehicle and its load from collisions.
Only use the SX5 on vehicles with electrical drives (e.g. servo) or electrically controlled drive and braking. The Safety Zone
must be configured so that the mobile vehicle can come to a complete stop before a collision can occur. If it is not possible
to completely safeguard the vehicle, including trailers, protruding or overhanging loads, etc., during the full length of travel,
including curves, use additional safeguarding, such as additional SX5 or bumper/edge switches.
The following instructions are general in nature and are intended to provide guidance to safely install the SX5 on mobile
vehicles. It is not possible to give exact recommendations for all mobile applications; the designer/user must also comply
with the vehicle manufacturer’s recommendations and all applicable regulations and standards. See also the warning and
the basic installation guidelines.
Safety standards covering mobile vehicles or automated/automatic guided vehicles (AGV) include:
• BS/DIN EN 1525
―
Driverless Industrial Trucks and Their Systems
‖
• ISO 3691-4
―
Driverless Industrial Trucks and Their Systems
‖
• ANSI/ITSDF (ASME) B56.5
―
Safety Standard for Guided Industrial Vehicles
‖
• IEC 61496-3
―
Requirements for Active Opto-Electronic Protective Devices Responsive to Diffuse Reflection
(AOPDDR)
‖
The user must also regularly check the safeguarding function of the SX5, and the speed and braking functions of the mobile
The user must instruct all individuals that may interact with the mobile vehicle (at a minimum) to:
• not approach the vehicle directly or from the sides while moving
• familiarize themselves with warning signals or lights/beacon
• familiarize themselves with the size of the Warning and Safety Zones
