1 Counter value ³ comparison value ®
output is set and hysteresis
activated
2 Leave hysteresis range ® output is reset
3 Counter value ³ comparison value ®
output is set and hysteresis
activated
4 Leave hysteresis range, output remains set for counter value ³
comparison value
5 counter value < comparison value and hysteresis
active ® output
is reset
6 counter value ³ comparison value ® output is not set for hyste-
resis active
7 Leave hysteresis range, output remains set for counter value ³
comparison value
With reaching the comparison condition the hysteresis
gets active. At
active hysteresis the comparison result remains unchanged until the
counter value leaves the set hysteresis range. After leaving the hyste-
resis range a new hysteresis is only activated with again reaching the
comparison conditions.
1 Counter value = comparison value ® output is set and hysteresis
activated
2 Leave hysteresis range ® output is reset and counter value <
comparison value
3 Counter value = comparison value ®
output is set and hysteresis
activated
4 Output is reset for leaving hysteresis range and counter value >
comparison value
5 Counter value = comparison value ®
output is set and hysteresis
activated
6 Counter value = comparison value and hysteresis active ® output
remains set
7 Leave hysteresis range and counter value > comparison value ®
output is reset
