Start-up and configuration
Fail-safe position set: ATO. To change the direction of action:
Î
Enable configuration (section 7.1).
1. Turn until Code P3 appears.
2. Press to confirm the selected code. P3 blinks.
3. Turn to set the fail-safe position ( ATO or ATC ).
4. Press to confirm the selected fail-safe position.
For checking purposes: After successfully completing initialization, the positioner display
must read 0 % when the valve is closed and 100 % when the valve is open.
The changed fail-safe position first becomes effective after the positioner has been re-initial-
ized.
7.4 Initializing the positioner
Î
For positioners with optional limit contacts, read section 7.6 before initializing the posi-
tioner.
During initialization the positioner adapts itself optimally to the friction conditions and the
signal pressure required by the control valve.
Risk of personal injury due to moving parts on the valve.
Î
During initialization, do not insert hands or fingers into the valve yoke and do not touch
any moving valve parts.
Î
Do not block the actuator stem.
The process is disturbed by the movement of the actuator stem.
Î
Do not initialize the positioner while the process is running and only after isolating the
plant by closing the shut-off valves.
