Operation The setpoint vertex values can only be input at 12.SFCT=FrEE. You may only enter a strictly monotonous characteristic, and two consecutive vertex values must differ by at least 0.2 %. 34.DEBA Dead zone of the controller At dEbA = AUto the dead zone in automatic operation is adapted continuously to the requirements of the control circuit. The dead zone is gradually increased on detecting a control oscillation. The reverse adaptation takes place by a time criterion. In the other discrete settings the fixed value is used for the dead zone. 35.YA 36.YE Manipulated variable limiting start (see figure 4-9 and 4-10) and Manipulated variable limiting end (see figure 4-9 and 4-10) With the parameters “YA” and “YE” the mechanical actuating distance (from stop to stop) is limited to the set values. In this way the mechanical setting range of the actuator can be limited to the active flow and the integral saturation of the commanding controller avoided. . NOTE YE must always be set to greater than YA. 37.YNRM Manipulated variable standardization (see figure 4-9 and 4-10) With limiting of the manipulated variable (by “35.YA” and “36.YE”) two different scalings are produced for the display and the position feedback via the current output (MPOS or FLOW). The MPOS scaling shows the mechanical position (0 to 100%) between the hard stops of the initialization. This is not affected by the parameters “35.YA” and “36.YE”. The parameters “35.YA” and “36.YE” are displayed in the MPOS-scale. The FLOW-scale is the standardization (0 to 100%) to the range between “35.YA” and “36.YE”. The setpoint w (0 to 100%) is always referred to this range. This gives (also by using valve characteristics) a quasi--flow--proportional display and position feedback Iy. To calculate the control difference, the setpoint is also shown in the appropriate scale on the display. 92 SIPART PS2 Manual A5E00074631-03

The tight closing function can be activated on one side or for both limit positions. YCLS becomes active when the setpoint is below the value set with parameter “YCDO” or above that set with parameter “YCUP”. SIPART PS2 Manual A5E00074631-03 93
