Sensitivity Adjustment (except Background Supression Model) • Referring to the table below, adjust the sensitivity of the SA1U photoelectric switch when necessary, such as when the through- beam model is used to detect small or translucent objects or the reflective model is affected by background. The table explains the status of operation LED when the operation mode is set to light ON. • After adjusting the sensitivity, make sure that stable LED turns on at stable incident and stable interruption. 11 SENS.
