Open Stop Action
The actuator can be set to stop in the open direction when it reaches the open position limit or when it
reaches the defined open torque/thrust setting value (see section 5.2.1).
Close Stop Action
The actuator can be set to stop in the close direction when it reaches the close position limit or when it
reaches the defined close torque/thrust setting value (see section 5.2.1).
5.2.4 Input / Output Setup
Demand Deadband (%)
The demand deadband sets the expected positioning accuracy of the actuator and is dependent on
various factors including actuator output speed, number of turns and valve torque. The actuator will run
until it reaches a position within the demanded deadband. The actuator will not restart until the
demanded position exceeds the extent of the deadband.
Demand Damping Clockwise (secs)
Setting a value greater than 0 will apply a delay in the clockwise direction, temporarily inhibiting
movement when a change to the set point signal occurs.
Demand Damping Anti-Clockwise (secs)
Setting a value greater than 0 will apply a delay in the anti-clockwise direction, temporarily inhibiting
movement when a change to the set point signal occurs.
4-20mA Output
Specify whether the 4-20mA output provides feedback for Valve Position or Valve Torque/Thrust.
5.3 Advanced Settings 1
5.3.1 Tight Shut Off
Valve tight shut off Open position (%)
This is the minimum position required to fully open (tight shut off) the valve.
Valve tight shut off Closed position (%)
This is the maximum position required to fully close (tight shut off) the valve.
5.3.2 Obstruction Action Active
If enabled, the actuator will back off movement if the maximum torque/thrust is exceeded during
travel. The actuator will make 3 attempts to back off and return to the set point. If disabled, the
