DMU318…W Device functions and indicators – switching output The sensor has a button for setting switching output OUT1 and analog output Analog OUT. Use the teach button to perform the 1-point teach, the 2-point window-teach and to changeover the switching function (NO contact/NC contact). Device status and switching states for OUT1 are indicated as follows by means of a yellow LED: Switching output OUT1 1-point teach (1 switching point)
LEDs flash at 8Hz until an error-free teach event is performed. 1) See table "Switching behavior with 2-point window-teach as a function of the switching function" Leuze electronic GmbH + Co. KG In der Braike 1 D-73277 Owen DMU318-400.W…-M12 - 01...

DMU318…W Adjusting the switching function (NC/NO) via the teach button The switching function of the sensor is preset as follows on delivery: OUT 1: NO contact The output function can be switched from NO contact (NO - normally open) to NC contact (NC - normally closed) and vice versa. If the switching function is changed, the switching output is changed to the opposite state (toggled).

DMU318…W 1-point teach of the analog output First activate the previously described teach mode for output Analog OUT. By selecting an object distance within the scanning range, the characteristic curve of the analog output can be adjusted. If an object is located outside of the taught measurement range, an error signal is output. A different analog signal is output here by the sensor for the errors "distance too close: object outside of the measurement range"...

DMU318…W Multiplex operation In this operating mode the mutual interference of adjacent sensors can be reliably avoided. For this purpose, up to 4 sensors of the same type are wired together in a network according to the following diagram. The devices operate in multiplex operation with a cyclically time-delayed transmission pulse and are switched to a passive state outside of the active phase, whereby the states of the outputs are frozen until the next active phase.
