Alarm Function
Pneumatic Leakage
Applicable for Posidapt –Super and Ultra
This parameter is used to determine possible pneumatic leakages. Depending on the
direction, changes in the position and the internal manipulated variable used for it are
continuously recorded and filtered for this purpose. The filter result is used to form an
indicator, which allows drawing a conclusion about a possible leakage.
The current value is displayed in the “Pneumatic leak” in Values and Counters under Counter
Thresholds and Trends. The device triggers a fault message if the current value exceeds one
of the three configurable limit thresholds.
Threshold Limit 1
Use this sub-parameter to set the factor for the formation of limit threshold 1.
• Off - Factory default
This parameter value does not trigger any message or alarm.
• Custom
The threshold 1 fault message is displayed when the limit threshold 1 is exceeded. The value
can be set from 0.1 to 20.0%.
Threshold Limit 2
Use this sub-parameter to set the factor for the formation of limit threshold 2.
• Off - Factory default
This parameter value does not trigger any message or alarm.
• Custom
The threshold 2 fault message is displayed when the limit threshold 2 is exceeded. The value
can be set from 0.1 to 20.0%.
Threshold Limit 3
Use this sub-parameter to set the factor for the formation of limit threshold 3.
• Off - Factory default
This parameter value does not trigger any message or alarm.
• Custom
