Short-Circuit Protection
RightSight photoelectric sensors provide short-circuit protection (SCP) on the output
leads. This feature is intended to protect the sensor from damage in the event that the
output load is shorted to ground. If this condition does occur, the SCP will activate and
the orange LED wil flash until the source is removed (power must be reset for AC/DC
models). The SCP limits are set to 100 mA over the entire voltage range for both DC
and AC/DC models.
