Manual Operator
This section presents installation and operation instructions for the manual operator used with 1069 actuators.
Note
When the 1069 actuator is equipped with an auxiliary manual operator, make certain that a cylinder bypass valve (key 53) is
installed and used to equalize cylinder pressure during handwheel operation. Operating the manual operator by itself against the
force of differential cylinder pressures will be difficult or even impossible.
Installation
Note
To aid in installation, make sure that the manual operator is in the engaged position during installation.
To install the manual operator, perform the following steps:
and spacer (keys 62, 68, and 67).
2. Note the valve disk or ball position and direction of rotation.
3. Align the four zero marks on the end of the valve shaft with the four zero marks on the inside end of the actuator
Note
To ensure that the adaptor zero marks are oriented correctly, make sure that the relative position of the travel indicator (key 69)
on the travel indicator scale (key 70) corresponds to the open or closed position of the valve.
5. Check that the position of the travel indicator corresponds with the open or closed position of the valve. If the travel
indicator is not positioned correctly, repeat steps 2, 3, and 4 of this procedure until the correct position is obtained.
Engaging and Disengaging the Manual Operator
To engage or disengage the manual operator, perform the following steps:
1. To change from the engaged to the disengaged position, or vice versa, temporarily pull the declutching handwheel
out from the gear box (key 53) as far as it will go.
2. Rotate the declutching handwheel 180 degrees in either direction (clockwise or counterclockwise).
