Set Stroke Limits
This routine allows the actuator to be configured according to the type of valve it is
mounted on.
The following parameters will be set:
•
Opening and closing torque limits: from 40% to 100% of the nominal torque.
The nominal torque corresponding to 100% is set in-house and is stated in the
nameplate menu for reference.
•
Close direction: clockwise (CW) or counterclockwise (CCW). Most valves require
clockwise rotation of the stem when viewed from the handwheel. Engage the
manual override and check if the valve closes with clockwise or counterclockwise
rotation of the handwheel.
•
Close and open limits type: by position or by torque. Use the table below
to choose.
