・For output 1 (Pin4, black wire), 5 types of teaching are usable by button
operations.
・For output 2 (Pin2, white wire), teaching is not usable by button operations.
However, output 2 teaching can be executed by the communication
commands of IO-Link (only 2-point teaching and background teaching is
usable).

This is the basic setting.
1. Press the button quickly without any objects (longer than 25 ms and shorter than 1s).
・The threshold value is set at a distance between background and object.
・Maximum detection distance is set (threshold value is set with HL150□: 150
mm, HL500□: 500 mm as a teaching point) when teaching is performed with
either the first or second point without detected object or background.
・Shown above is applicable to the case of N.O. output logic. In the case of N.C.,
this is inverted.

・This can be executed if setting [Background] when executing Teaching
Selection in "6 Detailed Settings"( page 9)
([Background] is the factory setting.)
・This is suitable for detection of an object from which small amount of light is returned to
the receiving surface (such as mirror, uneven, and low reflectance).
・
This teaching can be executed if setting [Normal] when executing Background Reference
Teaching Selection in "6 Detailed Settings" ( page 9)([Normal] is the factory setting.)
■Background Teaching [Teach 3sec (Background)]
■Background Reference Teaching (Normal) [Ref. Tech (Normal)]
Use to detect an object closer than the background.
Use to detect something shaped complicatedly.

・The threshold value is set on the near side to the background.
・If teaching is executed without any backgrounds, the maximum detecting
distance (HL150□: 150mm, HL500□: 500mm) will be set as the threshold
