10.2.2.8 Description of parameter 35
35.YCLS - tight closing manipulated variables
Use this parameter to move the valve using the maximum torque of the actuator (permanent
contact of piezo valves) into the seat. The tight closing function can be activated on one side
or for both end positions. "35.YCLS" becomes effective when the effective setpoint is below
"36.YCDO" or above "37.YCUP". For this purpose, see the picture below the also-see link.
Note
Activated tight closing function
If the tight closing function is activated, the monitoring of control deviation in the
corresponding overrun direction is switched off for the "45. LIM" parameter. "YCDO: < 0 %"
and "YCUP: > 100 %" are applicable in such a case. This function is mainly advantageous
for the valves with soft seats. In order to monitor the end positions for a long time, we
recommend activating the "F. ZERO" and "G. OPEN" parameters.
The factory setting is "no".
