Outputs (OSSD) :

The outputs (OSSD) of the XORF-SA2 product have been designed to detect any failure:

- a short circuit between OUT1 and OUT2

- a ground or 0V connection between OUT1 or OUT2

or any fraud :

- a short-circuit between IN1 and OUT1 or OUT2

- a short-circuit between IN2 and OUT1 or OUT2

- a setting at positive potential of OUT1 or OUT2

Pulses are added to the outputs to perform the diagnostic functions. The pulse duration and period do not affect the control of inductive loads. If an indicator is controlled by one of the outputs OUT1 or OUT2, a slight flickering may be visible depending on the indicator technology used.
