9.5.6.4 Limit value - define alarm type
With this function, you can define the alarm type. "High" triggers the alarm when
the limit value is exceeded, "Low" triggers the alarm when the value falls below
the limit value.
In case of "HIGH", the hysteresis slows down the triggering of the relay until the
measuring result falls below the set limit value by more than 2 % of the
measuring range.
In case of "LOW", the hysteresis slows down the triggering of the relay until the
measuring result exceeds the set limit value by more than 2 % of the measuring
range.
1. Select the ALARM TYPE menu item in the LIM. VALUE menu and press
[ENTER].
2. Select HIGH or LOW from the list and press [ENTER].
