4. Insert a padlock (not furnished by Emerson Automation Solutions) to prevent the mounting plate assembly from
rotating.
To Unlock the Actuator
1. Remove the padlock. Loosen the jam nut (key 40), and unscrew the threaded bolt until it no longer protrudes inside
the housing.
Note
Ensure the mounting plate assembly bolt is unthreaded far enough that the actuator lever will not contact the bolt during normal
actuator operation.
2. If the mounting plate assembly is to be left partially threaded into the housing, lock it with the jam nut (key 40) so
that it cannot be screwed further into the housing and interfere with normal actuator operation.
