Switch Actuator with Secure
36
It is able to start the object “Change Threshold value 1” when enabled, and change the threshold 1
value by the bus; on the other hand, it cannot change the value when disabled.
However it is not allowable to change the “Threshold 2 value” by the bus.
Parameter “Threshold behaviour”
The parameter defines the hysteresis status of “threshold 1 value” and “threshold 2 value”. Option:
Without hysteresis
With hysteresis
The hysteresis can avoid the unnecessary behaviour caused by the input value if its value is
between two threshold values.
Parameter “If falling below lower thereshold output status is”
Parameter “If between lower and upper output status is”
Parameter “If exceeding upper threshold output status is”
These parameters are used to define the relay action in the object “Threshold input”. Options:
Unchange
Contact open
Contact close
When it is “With hysteresis”, the parameter “If lower < object value < upper, contact position” is not
visible and now the object is no action.
