Description: Meaning:
Used The setting determines whether the upper limit for the Main Alarm should be used.
If it is not used, the following settings (limit value and hysteresis) are not possible.
Limit Value The (upper) limit value is the switching point, beyond which the main-alarm is
triggered.
Hysteresis Hysteresis is the difference between the switch-on and switch-off points at the limit
value. The switch-on point is the limit value plus half of the hysteresis, and the
switch-off point is the limit value minus half of the hysteresis.
