Min. input limit: 0.0
Protection level: 7/2
Sets the filter time for generating the SGA n<n
The filtering must be activated by setting bit 16 in MD36901 $MA_SAFE_FUNC-
TION_ENABLE to 1.
With default value 0, filtering is not active.
By parameterizing a filter time not equal to 0, the response time of the

Sets the hysteresis threshold for generating the SGA n<n
In addition to the hysteresis, this MD is also used to check the speed in the two monitoring
channels against threshold n
