7-1 Safety Outputs

This product is designed for use on a 24 VDC, negative ground (protective earth) electrical system only.

Never connect the F3SL 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 is severe operator injury.

The F3SL 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 500 milli-

amps of current at 24 VDC. In the machine stop state, the outputs are not electrically conducting.

Note: The safety outputs must have a minimum load or the F3SL system will enter a alarm condition. For the

purpose of testing prior to final installation, this load can be supplied by a 10K ohm resistor (included in

documentation kit). See Figure 7-1 for details .

This is not a safety output. F3SL systems suplies one PNP-type auxiliary output.In the on state, this Auxiliary

output will source up to 100mA, and will be on when the safety outputs are on. (Follow mode)
