6. Place the actuator onto the valve bonnet
(2) and secure it with the ring nut.
7. Determine the lower and upper signal
pressure range values.
The lower signal pressure range value
corresponds to the minimum value of the
bench range or operating range (see
section 5.3 for adapted travel range).
The upper signal pressure range value
corresponds to the maximum value of the
bench range or operating range (see
section 5.3 for adapted travel range).
8. Connect the signal pressure. See sec-
tion 5.2.
9. Screw on the stem connector nut (9) by
hand until it touches the actuator stem
(A7).
10. Turn the stem connector nut a further
quarter turn and secure this position with
the lock nut (10).
11. Position clamps of the stem connector
(A26/27) and screw them tight.
12. Align the travel indicator (84) with the tip
of the stem connector clamp.
