Operation
This table describes the different operating phases of the operation-idle timer.
Phase
Description
1
On the rising edge of the E input (on-delay) , time-out tri is launched (time base of 0.1ms).
2
When time-out tri is over, the x output changes to 1.
If the high status of input E lasts less time than tri, output x stays at 0.
3
On the falling edge of the E input (off-delay) , time-out tfi is launched (time base of 0.1ms).
4
When time-out tfi is over, the x output changes to 0.
During time-out tfi, if the low status of input E lasts less time than tfi, output x stays at 1.
Note: The x Aux output is at 1 as long as input E or output x is at 1.
