Dead zone monitoring
This parameter activates the monitoring of the dead zone adaptation.

Prerequisite for the function is the setting of parameter “34.DEBA”

= Auto.

Threshold for the monitoring of the dead zone adaptation.
This value (%) can be used for the automatic adaptation of the dead

zone. If the dead zone exceeds the set value, the threshold 3 error

message is triggered. The three-level error message is not imple-

mented for dead zone monitoring.

Zero point offset
This function is for detecting when the lower stop has changed its value

compared to the value during initialization by more than the set

thresholds. Monitoring is only possible if the valve is within the tight

closing function. The activation of the “bottom tight closing function”

(parameter “39.YCLS”) is therefore prerequisite.

Threshold 1
First threshold for monitoring the lower limit stop. If the set absolute

value is exceeded during “bottom tight closing”, this will trigger the

threshold 1 error message.

Threshold 2
Second threshold for monitoring the lower limit stop. If the set absolute

value is exceeded during “bottom tight closing”, this will trigger the

threshold 2 error message.

Threshold 3
Third threshold for monitoring the lower limit stop. If the set absolute

value is exceeded during “bottom tight closing”, this will trigger the

threshold 3 error message.
