9-2-6 Cable Assemblies
Receiver cable connections are color coded red and emitter cable connections are black. Details of the pin-out
connections for the OMRON-supplied connector are provided in Table 3-1.
9-2-7 Input Power Requirements/Connections
The F3SL system operates directly from 24 VDC ±20%. Power to the F3SL system must come from a dedicated
power supply which meets the requirements of IEC 60204-1 and IEC 61496-1. The F3SL system internally gen-
erates voltages for its own use. No other devices should be connected to these voltages.
9-2-8 Special Requirements for Perimeter Guarding
In perimeter guarding applications the F3SL system detection zone is placed around the outside perimeter of a
guarded machine or robot. This placement leaves space for personnel to stand between the detection zone and
the hazardous machine.
In this case, the guarded machine must only be restarted using a switch located outside and with a full view of
the area of hazardous motion. Operation of the F3SL system in the start/restart interlock operating mode is suit-
able for perimeter guarding.
9-2-9 Marking Minimum Object Resolution
Serial number labels on the emitter and receiver indicate three possible minimum object resolutions. During in-
stallation, use a permanent marker to obscure the object resolutions not set. This will depend on whether no
floating blanking, 1-beam or 2-beam floating blanking is set. See Section 5-3-1 for information.
9-2-10 Presence Sensing Device Initiation
Using the light curtain to initiate a machine after an object is removed from the sensing area is called Presence
Sensing Device Initiation (PSDI). Use of PSDI places additional requirements on the guarding and safety con-
trols. It can restrict advanced light curtain features such as Floating Blanking and Exact Channel Select. Good
sources of reference for PSDI include: ANSI RIA 15.06-1999, OSHA 1910.217(h), and ANSI B11.2-1995.
