17.11.3 Defining the hysteresis
A hysteresis can be defined for the alarm output R1. This prevents a constant triggering
of the alarm when measured values fluctuate marginally around the limit.
The hysteresis is a symmetrical range around the limit. The alarm will be activated if the
measured values exceed the upper limit and deactivated if the measured values fall be-
low the lower limit.
If the switching condition
MIN
or
MAX
is selected in the scroll list
func
:
• Enter a value for the hysteresis or enter zero to work without hysteresis.
• Press ENTER.
Example
physical quantity: mass flow rate in kg/h
Quantity Limit:
1 kg
Example
physical quantity: mass flow rate in kg/h
Low Limit:
60 kg/h
The unit of measurement of the physical quantity is changed to kg/min. The new limit
to be entered is 1 kg/min.
Example
High Limit:
30 kg/h
Hysterese
:
1 kg/h
The alarm is triggered for measured values > 30.5 kg/h and deactivated for measured
values < 29.5 kg/h.
