E3ZM-V
Automatic teaching (Remote)
1. Send a pulse with a duration of at least 2 s but less than 10 s min. to the remote control input (pink).
2. Teaching will be performed automatically when the mark (the light level with the shorter detection time) passes
through the beam spot.
• Make sure the mark passes through the beam spot for at least 1.5 ms.
• Pass the mark through the beam spot at least seven times to complete the teaching process.
• There must be a difference in light intensity between the mark and the background for teaching to be successful.
3. Detection will begin and the output will turn ON when the mark (the light level with the shorter detection time) is
detected.
Note: Determine when teaching has been completed by confirming that the output turns ON for the mark and OFF for the background. If the output does not turn ON
for the mark and OFF for the background within one minute after the remote control input is applied, teaching has not been successful. Apply the remote control
input again.

Precautions for Using Automatic Teaching (Remote)
• With automatic teaching (remote), the output is always turned ON for the light level with the shorter detection time. Use 2-point
teaching (manual) to turn OFF the output for the light level with the shorter detection time.
• Faulty detection is possible when using automatic teaching (remote) if there is considerable movement in the sensing object or
if the surface of the object is stepped or contains protrusions.
In cases such as these, use 2-point teaching.
• Do not use automatic teaching for backgrounds that are not monochrome.
