Remarks
Limit transgression
when exceeding or
dropping below value
*with regard to the setting
"zone", the difference between
the limits and the set
hysteresis should be ≥ 3x.
Is active in the direction
of cancellation of limit
violation.
Results in message and alarm
and shutting-off of the
corresponding metering.
Off: function off,
no message, no alarm.
