Installation & Setup Guide
Quick Setup Wizard
If the valve is to be commissioned over its full stroke the quick
setup wizard is a fast and efficient way to set the end of
travel limits.
The quick set up wizard will allow the actuator to find the
end of travel by measuring the output torque.
If the valve is not required to operate over full stroke it is
possible to set a fixed OPEN limit.
Select Quick Setup Wizard.
Set torque limits
The default torque values for the Auto setup are automatically
set to 40% of rated torque in both directions. Adjust if more
torque is required to move the valve through stroke.
Set basic actuator parameters
The MOV tag can be edited. Use the keyboard to edit
the MOV tag field.
Shaft Action
Select direction to close the output shaft to suit valve
operation.
Close / Open Stop
Set the end of travel stop function for Torque or Limit to suit
the characteristics of the valve.
Torque
The actuator can be set to apply its selected output ‘Torque’
to the valve at the end of travel where tight shut off is
required.
Limit
Alternatively it can be set to the ‘Limit’ function to disengage
motor drive and stop the valve at a predetermined position
where the valve does not require the seating force to be
applied to the valve seat or end of mechanical valve travel.
Click on the ‘START’ box to save changes to the actuator and
initiate the Auto Setup routine.
