Checkout Procedure
After Installation and adjustment, run the system through several complete
open/close cycles to be sure that all components are functioning correctly.
Check to be sure that the actuator responds to the controller and operates
the valve properly. Check for proper voltage. Check for operation of the
linkage without binding.
!
CAUTION: The actuator should not be stalled by the valve. The
actuator may be damaged if it is not free to complete
its full stroke.
