Applications • Delay on operate: Lead timing circuits (e.g. preheating); delay times in control systems: delayed starting of plant components, e.g. starting of slipring motors (switching starting resistors), burner controls, escalators, elevators • Release delay: After-run timing, e.g. fans, lighting controls, staircase lighting, minute lighting, delayed switching to emergency generating set/lighting Without auxiliary voltage: used for release times < 5 minutes With auxiliary voltage: used for release times > 5 minutes and for very short operating times • Flasher timers: trigger fault indicators...

Setting If the function switch is altered during operation, the new setting is valid immediately (like a restart of the relay). A new adjustment of the time or time range is also immediately valid. Please note, that a change of function, time range or time setting during elapse of time can lead to unintended switching of the output contacts. Adjustment assistance The flashing period of the yellow LED is 1 s ± 4 % and can be used to adjust the time. Especially on the lower end of scale and for long times it is suitable as the multiplication factors between the different time ranges are exact without...
