Adjustment of the 4 mA and distance away from the sensor. 20 mA LINEARITY adjusters must be performed with the standard target at positions of 20% and 100% of the rated detecting distance away from the sensor. Linearity Adjustment Method 1 2. Turn the 4 mA LINEARITY adjuster counterclockwise so that 1. Connect an ammeter across terminals 1 and 2. The the SPAN indicator remains OFF. Then slowly turn the illustration shows the sensor connected to an amplifier adjuster clockwise until the indicator illuminates. Stop through socket P2CF-11. turning the adjuster at the position where the SPAN indicator illuminates. 3. Set the standard target at the rated detecting distance away from the sensor. 2. Place the standard target at 20% of the rated detecting distance away from the sensor unit. 4. Slowly turn the 20 mA LINEARITY adjuster clockwise until the SPAN indicator goes OFF. Then turn the adjuster counterclockwise until the indicator illuminates. Stop turning the adjuster when the SPAN indicator illuminates. 3. Turn the 4 mA LINEARITY adjuster slowly clockwise (to increase the output current) or counterclockwise (to decrease the output current). Set the adjuster to a position that reads 4 mA output on the ammeter. SENSITIVITY ADJUSTMENTS Place the standard target at the specified position. If the target moves in parallel with the surface of the sensor unit, make the adjustment after determining the position using the following procedure. 4. Place the standard target at the rated detecting distance. 1. Adjust the linear output according to Adjustment Method 1 or 2. 2. Calculate detecting distance X using the following formula: 5. Turn the 20 mA LINEARITY adjuster slowly clockwise (to S increase the output current) or counterclockwise (to X = S = setting distance decrease the output current). Set the adjuster to a position 0.8 that reads 20 mA output on the ammeter. 3. Adjust the distance between the sensor and the object to be detected to distance X. 6. To fine tune the adjustment accuracy of the output current, repeat the adjustment steps for 4 mA and 20 mA Slowly turn the SENSITIVITY adjuster clockwise (toward HIGH) LINEARITY adjusters. and stop turning when the OPER. indicator illuminates. Move the target to confirm that the OPER. indicator illuminates when the object to be detected is at the specified position and that the indicator goes OFF when the target is moved away from that position. If the target moves in parallel with the surface of the sensor unit, place the sensor at distance S. 73 onlinecomponents.com E2CA E2CA SELECTOR SWITCHES Selection of Operation Modes Compensation for Different Cable Lengths OUTPUT Set the CABLE selector switch to the required position The output transistor turns ON when the according to the length of the sensor cable being used: 3 m target is detected.
