8.3 Initializing the actuator
Risk of injury due to the actuator stem extending or retracting.
Do not touch or block the actuator stem.
The process is disturbed by the movement of the actuator stem.
Do not perform the initialization while the process is running. First isolate the plant by closing
the shut-off valves.
The initialization is performed in Code5. During initialization, the actuator stem moves from
its current position to the 100% end position. Starting from the 100% end position, the actu-
ator stem moves to the 0% end position.
The 0% and 100% end positions depend on the operating direction used (section9.3).
Î Before initialization, mount the actuator on the valve as described in section5.1.
