After the preselected on-delay time 100 s the output relay switches into its activeposition and the LED TRIPPED lights up continuously.If the actual monitoring value falls below the response value minus the hysteresis of 3 %,the output relay switched back into its off-position.If falls below before the on-delay time is reached, the LED TRIPPED goes out - see functiondiagram.NMI 1001 1 -- 15 A:Response valueOn-delay timeFunction12 A AC/DCnounderflow, 10 % hysteresis, closed circuit principleSettings• Measuring range 1,5 to 15 A (terminal B1 / B2)• Poti Vx at 0,8 (0,8 x upper limit of measuring range 15 A) = 12 A• Rotary switch ON DELAY at " - " (no delay)• Function rotary switch at < 10If the measuring value falls below of the response value of 12 A, the output relay switchedinto its off-position without a on-delay time, and the LED TRIPPED lights up.If the actual measuring value exceeds the response value plus the hysteresis of 10 %, theoutput relay goes in its operating position.
