9. easyE4 inside9.4 Time behavior of the inputs and outputs9.4.2.2 Additional delay time due to bouncing pushbuttonsFigure 242: Pushbutton with bounceIf a button or switch bounces (A), the delay time may be extended by 20 ms (16.7 ms)(A).Delay time with DEBOUNCE deactivatedWhen DEBOUNCE is deactivated, the delay time is reduced so that the easyE4 deviceswitches in shorter scan cycles tSC2 the appropriate input (contact) internally from 0 to1 (A) when a positive half wave is detected.Figure 243: Switching behavior with DEBOUNCE deactivatedIf a positive half-cycle is not detected the easyE4 switches off the contact (B).tSC2 (50 Hz) = 20 ms, tSC (60 Hz) = 16.7 msl Switch-on delay (normally):l I1…I12: 20 ms (16.7)l Off-delay (normally):l I1…I12: 20 ms (16.7)The appropriate values for 60 Hz are given in brackets.The procedure for changing the delay times is described in:→ Section "Time behavior of the inputs and outputs", page 506510 easyE4 11/18 MN050009 EN www.eaton.com
