Stairwell Light without Pre-Warning with Manual OFF (Fb_StairwellLight1)Function Description:The function block ‘stairwell’ operates as a dynamic, mono-stable flip flop. With arising signal at input “xSwitch“ at the output “xActuator“ is turned ON . Theduration of the stairwell time is set via parameter “dwT_10tel_s“. Should anotherrising signal occur at the input during the stairwell time, the time is reset and thepulse extended (retriggerable).The stop input sets the output signal to zero at any time (stairwell light with manualOFF).With the output set and the arrival of a signal on inputs “xSwitch“ and “xStop“ thestop input has the priority and the stairwell time will be discontinued. If the output isnot set and if the inputs are simultaneously set with a 1, the output is set and thestairwell time started.Subject to design changes WAGO Kontakttechnik GmbH & Co.
