Values
Name | Description |
---|---|
iTcMc_ValveTypeDefault | Standard method: Measurement in both directions of movement. |
iTcMc_ValveTypeAbrupt | This setting is provided on valves with an abrupt transition from the coverage area. This is only the case with very few valve variants, and without this setting it manifests itself through a very hard behavior, especially at the beginning of the automatic identification. |
iTcMc_ValveTypeDecomp | This setting is adapted to valves with pressure relief in the coverage area (h symbol). |
iTcMc_ValveTypeLinearP | With this setting, the identification is performed only in the negative direction. For the positive direction a linear characteristic curve is assumed, the endpoint of which is calculated from the maximum velocity in the negative direction using the set velocity ratio. |
iTcMc_ValveTypeLinearM | With this setting, the identification is carried out only in the positive direction. For the negative direction a linear characteristic curve is assumed, the endpoint of which is calculated from the maximum velocity in the positive direction using the set velocity ratio. |
iTcMc_ValveTypeCopyToP | With this setting, the identification is performed only in the negative direction. For the positive direction, the measuring points are calculated from the measuring points of the negative direction using the set velocity ratio. |
iTcMc_ValveTypeCopyToM | With this setting, the identification is carried out only in the positive direction. For the negative direction, the measuring points are calculated from the measuring points of the positive direction using the set velocity ratio. |
