Honeywell SYA14 Series Manual page 14

FF-SYA14, FF-SYA30 and FF-SYA60 Series light curtains are designed so a malfunction
or an interruption of the sensing field will immediatly cause the light curtain to generate a
stop signal. This stop signal will be generated automatically if a malfunction occurs in the
light curtain. All other machine control components that affect safety should also be
designed to the same high level of operation.
IMPROPER MACHINE REACTION
• Ensure the machine control is capable of stopping the machine at any point in the
cycle.
• Ensure that a loss of power does NOT impair stopping action of machine.
Failure to comply with these instructions could result in death or serious injury.
Figure 2-1 Point-of-operation Guarding (use FF-SYA14 and FF-SYA30 only)
Operator enters danger zone Operator enters danger zone
under the light curtain above the light curtain
Point-of-operation is defined as that area where a machine performs work (such as
cutting, shaping, boring, or forming) on a material.
FULL REVOLUTION MECHANICAL POWER PRESSES CANNOT BE STOPPED IN
MID-STROKE (OSHA 29CFR 1910.217). Do NOT use FF-SYA Series light curtains on
full revolution mechanical power presses.
Failure to comply with these instructions will result in death or serious injury.
For point-of-operation guarding, the light curtain(s) and any mechanical guards should be
installed so no one can stand between the light curtain and the danger zone. This may
require additional hard guarding, horizontal or angled positioning of the light curtain, or
additional light curtains.
