2Mounting M12 connectorIf the fixed ring loosens, the connector will come off, causing this product to gen-erate a communication error. Before use, check that the fixed ring is not loose .● Firmly tighten the fixed ring by rotating it.

Otherwise your changes will be lost.● If settings are configured simultaneously on the main unit side andon the IO-Link communication side, the settings that are applied lastwill be used.When you turn the power ON, the amplifier is in RUN mode. Press theMODE key (indicated by black arrow in the illustrations below) to switchfrom one mode to the next.RUN mode ● Displays the threshold value in greenand the incident light intensity in red.● Used for teaching, making fineadjustments to the threshold values(see page 3), and activating thekey lock function (see page 3).Sensing output operation mode ● Select either Light-ON or Dark-ON.The default setting is (Light-ON).● Refer to sensing output operationmode on page 4 for details.Light sensitivity setting mode ● Displays the light sensitivity settingand enables its setting● Refer to light sensitivity setting modeon page 4 for details.PRO mode● Used for advanced settings.● Refer to PRO mode on page 4for details.RUN mode7 Teaching● Please note that if the threshold values are very close to each other,objects may not be detected reliably.● Teaching is performed in RUN mode and during IO-Link communi-cation.There are different teaching methods available. Which teaching method isrecommended depends on the sensor type and whether the sensing objectis present or not present or moving.Sensing condition Recommended teachingmethodSensing object is present and easilydetectable. 2-point teachingSensing object is very small.Other objects are in the background. Limit teachingProduction line cannot be stopped andsensing object is moving Auto teachingAll teaching methods are available for the thru-beam, the mirror reflectiontype and the reflective type.
