2. Description and Operation
2.1 Overview
This chapter contains terms and concepts related to safety and the application of the FF-
SYA Series light curtain. The importance of the installer's role in the set-up and
installation of the machine guarding systems is discussed. The section also contains
specification and order guide information.
2.2 Machine Guarding and Perimeter Protection
FF-SYA14 and FF-SYA30 Series thru-scan light curtains are non-contact machine
guarding devices designed to increase the protection of operators of power driven
machinery (see Figure 2-1). The FF-SYA60 Series light curtain is designed for access
control of dangerous areas.
IMPROPER INSTALLATION OF FF-SYA SERIES LIGHT CURTAIN
• Install FF-SYA light curtains in accordance with this installation manual and applicable
local safety regulations (OSHA, ANSI, European standards).
• Allow entry into protected area by interruption of sensing field of the safety light curtain
or activation of other safeguarding device only.
Failure to comply with these instructions could result in death or serious injury.
FF-SYA Series light curtains generate a stop signal if the sensing field is interrupted.
Further operation is prevented until the sensing field is cleared. The FF-SYA Series light
curtain monitors itself continuously for component failures, misalignments, and dirt
accumulations. Small misalignments or dirt accumulation are indicated by a flashing LED.
If misalignment or dirt accumulations become too great or a component fails, a stop signal
is generated. Operation is prevented until the condition is corrected.
IMPROPER SYSTEM PERFORMANCE
• Comply with local safety requirements when designing machine control link, interface
and all control elements that affect safety.
• Install two independent safety relay contacts into machine control stop circuit controlled
by FF-SYA Series light curtain.
• Ensure two independent stop circuit relays have mechanically linked contacts to reliably
detect a welded contact.
• Using the FF-SRS59392 safety control module will provide fail-safe contacts to the
machine control stop circuit.
Failure to comply with these instructions could result in death or serious injury.
