FF-SYA Series

The FF-SYA main features are:
- COMPACT SIZE
The cross section of 42 x 55 mm

/1.65 x 2.16 in

makes
installation possible in tight spaces, especially with the help of
the small brackets supplied with the light curtains. The optional
FF-SRS59392 interface control module easily fits inside the
machine control panel with its 45 mm/1.77 in width DIN rail
mount housing.
- UNIVERSAL
The housing dimensions are the same for the 14 mm/0.6 in,
30 mm/1.2 in, 60 mm/2.4 in resolution light curtains. The ex-
tended protected heights range from 334 to 1830 mm/ 13.1 to
72.0 in, covering all industrial applications. The scanning range
makes it possible to use mirrors in order to protect several sides
of a machine with only one system.
- SMART
The FF-SYA is equipped with 2 fail-safe static outputs and an
optional full-featured safety control module is available for a
greater output current capability and manual restart functional-
ity. An integrated cross talk reduction system allows the scan-
ning range to be selected for the application distance. A cross
talk indicator flickers when emission from other systems is de-
tected, indicating that a different selection of the scanning
range is needed. The light curtain also has a signal strength
indicator which flickers if there is a slight misalignment of the
beams or front window contamination. Additional indicators
provide information on the outputs status, on the selected
scanning range and on failure diagnostic. Standard brackets
are delivered with the light curtain to ease the order process.
The housing has a T-slot mounting system to adapt brackets
anywhere along the housing. Quick disconnect connectors are
also delivered with the FF-SYA
JJJJJ
C2 light curtains.
- FULL FEATURED
The FF-SYA does not need a galvanic insulated power supply
since it includes its own means of galvanic insulation (DC/DC
converter). Compliance with the installation requirements of the
IEC/EN 61496-1 standard is therefore guaranted by design. The
integrated test input can be used to test the entire safety chain.
When connected to the FF-SRS59392 interface control
module, the FF-SYA provides a wide variety of advanced
functions: cross-monitored relays, final switching devices
monitoring for the control of external contactors or relays,
choice between automatic restart or start and restart interlock
as well as relay status indicators.
Cross-talk reduction system
The FF-SYA light curtain is based upon an infrared transmission between an emitter unit and a receiver unit. It is a requirement of
the IEC/pr EN 61496-2 standard that if a receiver R2 receives two signals transmitted by two different emitters E1 and E2, the
receiver R2 must turn to the alarm state. This happens if the receiver R2 is within the beam aperture angle and within the nominal
scanning range of the second emitter E1. The cross-talk detection indicator flickers on the receiver R2 to warn the installer.

A selector switch is available on the emitter units for the selection of the adequate emission power. This switch can be used to
eliminate this cross-talk phenomenon by decreasing the nominal scanning range down to 42 % or 54 % of its value. The front cover
is accessible and there is no need to remove unit from the machinery to select a different scanning range.
