8.1.2 Manual Control operation
1 The Manual Control has a "Push and Lock"
function:
-
To operate the Manual Control, use a
screw driver, push to activate and release
to de-activate the pilot valves.
-
If required turn it 45°, to lock it in position
and keep the actuator in its operated state.
2 In case of a Fail in Last Position configuration
with two manual controls:
-
The manual control on the right side
(default location) will pressurize the central
air chamber and cause the actuator to rotate
counter clock wise. For reverse acting FieldQ
actuators (Assembly code CC) the actuator
will rotate clock wise.
-
The manual control on the left side (Location
for 2nd Manual Control) will pressurize the
end cap air chambers and cause the actuator
to rotate clock wise. For reverse acting FieldQ
actuators (Assembly code CC) the actuator
will rotate counter clock wise.
-
In order to operate one of the manual
control, be sure the opposite manual control
is de-activated and unlocked.
3 It is possible to rotate the screw multiple cycles.
The unit will than toggle every 90° between
"locked" (1) and "unlocked" (0).
8.2 Speed control option
(see Figure 8.2).
The FieldQ can be supplied with a Speed Control
option. One throttle is required for Spring Return
actuators and up to two for Double Acting
actuators.
The speed control throttle controls the air flow
in and out of an air chamber and as such limits
the speed of the "Opening" and "Closing" stroke
simultaneously.
8.2.1 Mounting Speed Control throttle(s):
1 Remove the plug(s) at the side of the module
and turn in the throttle (1).
2 Spring Return actuators: Use the top entry only.
3 Double acting actuators: Use both bottom and
top entries.

Fig. 8.2 Speed control operation
-
For standard actuators, the top entry will
throttle the closing stroke.
-
For standard actuators, the bottom entry will
throttle the opening stroke.
-
For reverse acting actuators, the opposite
strokes will be throttled.
8.2.2 Adjusting Speed Control throttle(s):
1 Remove the nut cap (2).
2 Clockwise rotation of the adjustment screw
reduces the speed.
3 Counter clockwise rotation of the adjustment
screw increases the speed.
4 Replace the nut cap.
