Method #2 assumes the amplifier is wired for DARKON operation mode. Conditions Adjustment method The reflection factor of the object to be detected is equal to, or higher than, that of the background object. Use Method 1. The reflection factor of the object to be detected is less than that of the background object. Use Method 2. Adjustment Method 1 Adjustment Method 2 1. Set sensitivity adjuster to center position. 1. Set sensitivity adjuster to center position. 2. Turn the distance adjusting knob fully counterclockwise, for as many turns as necessary, to reach the shortest distance setting "S". 2. Turn the distance adjusting knob fully counterclockwise, for as many turns as necessary, to reach the longest distance setting "L". 3. Place the object to be detected in position. 3. Remove the object to be detected, if present. 4. Turn the distance adjusting knob slowly clockwise, from shortest distance setting "S" toward longest distance setting "L". Stop turning the knob when both LIGHT INCIDENT and STABILITY indicators light. This is the proper distance setting. 4. 5. Next, adjust the sensitivity. Turn the distance adjusting knob slowly clockwise, from longest distance setting "L" toward the shortest distance setting "S". Watch for the following combination of indicators to light: E3S-LS10: Stop turning the knob when both LIGHT INCIDENT and STABILITY indicators light. E3S-LS20: Stop turning the knob just before the STABILITY indicator goes out while the LIGHT INCIDENT indicator is lit. 5. Next, adjust the sensitivity. Detected object Background object Distance adjusting knob ■ SENSITIVITY ADJUSTMENT Setting sequence Detecting condition Step 1: Finding point A Step 2: Finding point B Step 3: Final setting Turn the sensitivity adjuster fully counterclockwise to the Minimum Setting. Place the object to be detected in position, then turn the sensitivity adjuster slowly clockwise until the LIGHT INCIDENT indicator lights. This is reference point "A". Remove the object to be detected, then turn the sensitivity adjuster fully clockwise to the Maximum setting. Turn the sensitivity adjuster slowly counterclockwise until the LIGHT INCIDENT indicator goes off. This is reference point "B". If the indicator is off at maximum setting, use the maximum setting as reference point "B". Set the sensitivity adjuster between reference points "A" and "B". Confirm that the STABILITY indicator lights when the object to be detected is in place and when removed from its specified position.

4. Example: Follow these steps to set the sensor for detecting an object at 5 cm: 1. Follow the ridge of the alignment into the groove of the sensor. (Refer to the drawing in Dimensions ). 2. Match the line indicating 5 on the alignment aid to the 5 on the back of the sensor (5=5 cm). 3. Starting from the most counterclockwise position, turn the distance adjusting knob clockwise until the indicator mark is in the center of the alignment aid.
