The switched output is set in dependence of the adjusted detect distance. V ia the push-button, the detect distance and operating mode can be adjusted (teach-in). T wo LEDs indicate operation and the state of the switched output. Safety Notes ‘ Read the operating instructions prior to start-up. ‘ Connection, installation and adjustment works may only be carried out by expert personnel. ‘ No safety component in accor dance with the EU Machine Dir ective Pr oper use zws ultrasonic sensors are used for non-contact detection of objects. Installation ‘ Mount the sensor at the installation site with the aid of the enclosed mounting plate. Maximum tor que: 0,5 Nm Fig. 1: Attachment with mounting plate ‘ Connect a connection cable to the M8 device plug. Fig. 2: Pin assignment with view onto sensor plug and colour coding of the microsonic connection cable Start-Up ‘ Connect the power supply . ‘ Carry out the adjustment in accor dance with the diagram.

Synchr onization Y ou can synchr onize as many sensors as you like. ‘ Apply a squar e-wave signal to the sync-input with pulse width t i and r epetition rate t p (Fig.3 and technical data). A high level on the sync-input will deactivate the sensor . Fig.3: External synchronization signal Checking operation mode ‘ In normal mode shortly pr ess the push-button.
