Figure 242: Pushbutton with bounce
If a button or switch bounces (A), the delay time may be extended by 20 ms (16.7 ms)
(A).
Delay time with DEBOUNCE deactivated
When DEBOUNCE is deactivated, the delay time is reduced so that the easyE4 device
switches in shorter scan cycles t
1 (A) when a positive half wave is detected.
Figure 243: Switching behavior with DEBOUNCE deactivated
If a positive half-cycle is not detected the easyE4 switches off the contact (B).
t (50 Hz) = 20 ms, tSC (60 Hz) = 16.7 ms

Switch-on delay (normally):
l
I1...I12: 20 ms (16.7)
