Description and Operation
Overview
This chapter contains terms and concepts related to safety and the application of the FF-SB 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.
Machine Guarding and Perimeter Protection
FF-SB12, FF-SB14 and FF-SB30 Series thru-scan light curtains are non-contact machine guarding devices
designed to increase the protection of operators of power driven machinery (see figure 1-1). The FF-SB15
Series light curtain is designed for perimeter guarding of dangerous areas.
IMPROPER INSTALLATION OF FF-SB SERIES LIGHT CURTAIN
• Install FF-SB 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 or other safeguarding device only.
• Consult local safety agency before installing FF-SB Safety light curtains.
Failure to comply with these instructions could result in death or serious injury.
FF-SB 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-SB 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.
