SECTION 10
Connection to the Machine control circuit
!WARNING
This product is designed for use on a 24 VDC, negative ground (protective
earth) electrical system only. Never connect the F3S-TGR-CL system to a
positive ground (protective earth) system. With a positive ground (protective
earth) wiring scheme, certain simultaneous shorts of both safety outputs may
not be detected and the guarded machine may not stop, resulting in severe
operator injury.
!WARNING
Never use only a single safety output to control the machine. Should this sin-
gle output fail, the machine may not stop, resulting in severe operator injury.
The machine must be connected using both safety outputs.
10-1 Input Power Requirements
The system operates directly from 24 VDC ±20%. Power to the system must
come from a power supply which meets the requirements of EN/IEC60204-1
and EN/IEC 61496-1.
The power supply must guarantee safe insulation from the mains voltage in
accordance with IEC60742 (Protective class III, double insulation) and be
able to cover a drop of supply voltage of at least 20 ms. OMRON offers suit-
able power supplies. Transmitters and receivers must be supplied from a
shared power supply and must be fused against over current. An external fuse
of 1A must be used.
10-2 Cables
The primary cables for the F3S-TGR-CL system are industry standard
shielded cables with an M12 female connector. The receiver and transmitter
incorporate a M12 male connector.
We recommend to use the F39-TGR-CVL cables to connect the F3S-TGR-CL
system to the machine control system.
