4 Teaching the Threshold (SET Mode)
✽ There are five methods that can be used for teaching, as described
below. Use the method most suitable for the application.
✽ Two-point teaching, positioning teaching, and automatic teaching
can be performed in RUN Mode.
For operating procedures, refer to the Instruction Manual provided
with the product.
✽ An error has occurred if OVER or LO is displayed on the
sub-display. If that occurs, repeat the operation from the beginning.
4-1. Setting the Threshold at Maximum Sensitivity
The threshold can be set to the maximum sensitivity.
This is useful when the longest detection distance is
required.
