Safety Outputs (OSSDs) waveform

Note 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.
The F3S-TGR-CL system receiver supplies two independent PNP type safety
outputs to provide run/stop signals to the guarded machine. In the MACHINE
RUN state, the safety outputs are electrically conducting and source 250mA
of current at 24 VDC. In the MACHINE STOP state, the outputs are not elec-
trically conducting.
For loads higher than 250 mA for each OSSD or AC current, please use exter-
nal safety relay units or forcibly guided safety relays and enable the EDM
function.
