Operation.
(Poppet Valves Shown)
The cylinder will cycle once regardless of multiple start signals
or how long the manual valve is actuated. Time of cylinder cycle
adjustment is up to one minute.

The cylinder extension can be delayed up to one minute after
the manual valve has been actuated by using a Norgren T.D.O.
