You have the possibility of setting the permissible value for the
controlling for each sensor type. When a measurement value lies
outside this limit value, the control will be discontinued. Basic load
control is only active in this case.
If the measurement value lies outside the limit value than a
warning is reported and the symbol

Operating Schematics / Display Symbols
Hysteresis
An hysteresis is installed here so that when in the
range of the limit value of the control module delta
switching is not constantly carried out between the
control and base load metering.
The hysteresis is approx. 2% of the measuring range:
– („Limit value up" minus „Limit value down") * 2 %
