Additional delay time due to bouncing pushbuttons
Figure 215:Pushbutton with bounce
If a pushbutton 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
easy800 device switches in shorter scan cycles t

the appropriate input
(contact) internally from 0 to 1 (A) when a positive half wave is detected.
Figure 216:Switching behaviour with DEBOUNCE deactivated
If a positive half-cycle is not detected the easy800 switches off the
contact (B).

I1…I12: 20 ms (16.7)
•
Off-delay (normally):
