Safety Distance

Method for calculating safety distance as provided by

International Standard ISO 13855-2002 (European

Standard EN 999-1999) (for intrusion perpendicular to the

detection zone)

Substitute K = 2,000 mm/s and C = 8 (d – 14 mm) in equation (1)

and calculate as shown below.

Use S = 100 mm if the result of equation (2) is less than 100 mm.

Recalculate using the following equation with K = 1,600 mm/s if the

result is over 500 mm.

Use S = 500 mm if the result from equation (3) is less than

Always maintain a safe distance (S) between the F3SL

and a hazardous part of a machine.

Failure to do so causes the machine to fail to stop before

an operator reaches the dangerous area and may result

in serious injury.

“Type Certification” specified in the Chapter 44. 2 of the Industrial

Safety and Health Law in Japan does not apply to independent

F3SL Sensors. This law applies to systems incorporating the

Sensor. When using the F3SL Sensor in Japan as a “safety device

for presses or shearing machines,” as specified in the Chapter 42

of the same law, apply for certification for the overall system.

The F3SL is classified under electro-sensitive protective

equipment (ESPE) in the European Union (EU) Machinery

Directive Annex IV, B, Safety Components, Item 1.

The following certification have been obtained for the F3SL from

EU Certification Bodies: EC type certification (type 4 ESPE) under

the Machinery Directive from TÜV Rheinland.

S = 2,000 mm/s × (Tm + Ts) + 8 (d – 14 mm) ........................... (2)

Where: S = Safety distance (mm)

Example:

S = 1,600 mm/s × (Tm + Ts) + 8 (d – 14 mm) ........................... (3)

the machine receives a stop signal to the moment the hazardous

part of the machine stops.

change from ON to OFF.

Tm = 0.05 s, Ts = 0.020 s, d = 30 mm:

S = 2,000 mm/s × (0.05 s + 0.020 s) + 8 (30 mm – 14 mm) =

500 mm.

Tm = Machine response time (s) *1

Ts = Safety light curtain response time (s) *2

d = Detection capability of the safety light curtain (mm)

Distances from Reflective Surfaces

Side view

Install the F3SL with minimum Distance D shown above from

reflective surfaces (highly reflective surfaces) such as metal walls,

floors, ceilings, and work pieces.

Do not used the product in atmospheres or environments that exceed

product ratings

Be sure to install the F3SL to minimize the effects of

reflection from nearby surfaces.

Failure to do so may cause detection to fail and may

result in serious injury.
