Note:
This QC44 control module can be equipped with
one or two pilot valves:
* One pilot valve is default and suitable for normal
operation of double acting or spring return
actuators.
* Two pilot valves are required for Fail in Last
Position function on double acting actuators.
* Actuator must be isolated both pneumatically
and electrically before any (dis)assembly is
begun.
* Installation, adjustment, putting into service,
use, assembly, disassembly and maintenance of
the control module must be done by qualified
personnel.
* Be sure that the actuator is correctly mounted
before connecting air supply and electrical
wiring (see Installation & Operation Manual
Bettis Q-Series Valve Actuator, DOC.IOM.Q.E)
* Check the module label for the right execution
(see figure 2.2)
* Check the type of actuator: single or double
acting (see figure 2.2).
* For mechanical installation of the module see
installation instruction leaflet DOC.BQC4.MTI.1,
as shipped with the module.
The enclosures of both Weather Proof and Explosion
Proof / Flame proof modules, have a IP66 or NEMA
4X, ingress protected rating.
2.1 Intended use
The Bettis Q-Series actuator is an integrated
concept for the automation of quarter turn valves,
dampers or other quarter turn applications. It
consists of two basic parts (see figure 2.1):
1. Pneumatic actuator
2. Control Module
The control module allows operation of the
actuator and supplies position feedback signals.

www.emersonprocess.com/bettis
- For re-adjusting the limit switches, see
procedure below.
5.2 Before re-adjusting the limit switches.
IMPORTANT
* Before mounting the actuator on the valve, be
sure that both the actuator and the valve have
the same “open” or “closed” position.
* Set the Mechanical stroke before setting the
limit switches.
5.2.1 Pneumatic and electrical connections
Make pneumatic and electrical connections before
adjusting the limit switch setting. See chapter 3
and 4.
10
5.2.2 Switch point setting and valve rotation
direction.
The QC44 is equipped with non-intrusive switch
adjustment. The adjustment screws are accessible
behind a small shield in the front of the module
(see fig 5.3).
This means that the switch adjustment can be done
without opening the module.
Normally valves are “Closed” after a clock wise
rotation.
- In this case the top adjustment screw (see
fig. 5.3), sets the switch point of the “Closed”
position and bottom adjustment screw sets the
switch point of the “Open” position.
- When you have a valve that is “Open” after a
clock wise rotation, the position feedback will be
reversed.
The table below indicates which re-adjustment
screw and terminals are related to the “Open” or
“Closed” switch point setting (see fig 16).

5.2.3 Working principles Switch Operating
Mechanism (see fig 5.2)
Switch point adjustment
The position of the lower pivot block (2) can be
changed by adjustment screw (10) and the position
of the upper pivot block (4) can be changed by
adjustment screw (9).
The Switch Operating Mechanism is intend to
operate the position feedback switches and allows
adjustment of the switch points in the open and
closed end positions. Factory setting is that the
switches are activated 15° before the end of the
open and closed stroke.
By adjusting the position of these pivot blocks the
switch points will be changed.
The adjustment screws (9 & 10) can be found
behind the shield (12) in front of the module. To
access the adjustment screws loosen the screw (11)
and rotate the shield (12) as shown.
Switch Operation
The rotation of the actuators pinion operates the
IPT device (1) which results in a linear movement.
The linear movement of the IPT device operates
lever (3). The lever amplifies the linear movement
of the IPT device and operates the switch operating
rod (5). Dowel pin (6) in the rod operated the levers
of the open and closed switch elements (8 & 9).
Caution: Do not force the
adjustment screws when
resistance is felt.
During adjustment there are three situations
that can damage the adjustment screw head and
internal mechanisms when forcing the adjustment
screws.
The lever is of the “floating” type. When the IPT
device operates the lever, it moves completely
upwards until it meets the upper pivot block (4). At
this point the lever will tip over and pull down the
switch operating rod (5) and operates the
bottom switch (7). When the IPT device moves back
the springs cause the lever to move completely
downwards until it meets the lower pivot block
(2). At this point the lever will tip over and push up
the switch operating rod (5) and operates the top
switch (8).
1. Pivot block (2) will be blocked at bottom if screw
(10) is rotated too much counter clock wise.
2. Pivot block (3) will be blocked at top if screw (9)
is rotated too much clock wise.
3. Pivot blocks (2&3) will interfere with each other,
if the adjustment screws (9&10) are rotated too
much in the direction according to their related
arrows.
Situation 1 and 2 may happen in combination with
situation 3.

IMPORTANT
The procedure below assumes:
- That the actuator and control modules are
according the factory settings.
If the switch setting is somehow lost or
forgotten, then consult paragraph 6.3 to
set the switch point setting back to factory
setting.
- That the actuator / valve assembly is closed
after a clock wise rotation (see chapter 5.2).
Below procedure assures that the position feedback
complies more accurately with the valve position
and will set the switch point at approximately
4° before the end of the stroke.
7. Turn bottom screw (9) clock wise (do not force
the adjustment screw) until the switch trips to
the “off state” (no signal).
8. Turn bottom screw (9) counter clock wise (do
not force the adjustment screw) until the
switch trips to the “on state”. This position represents the actual “open” position of the valve.
9. Turn the screw minimal a 1/2 turn counter clock
wise. The “open” position switch point is now
set.
10.Turn the shield (12) back over the adjustment
screws and fasten it with the screw (11) and
mount the main round cover back in place.

Fig. 8.1 Local Manual Control options
For commissioning, emergency or maintenance
purposes, the Bettis Q-Series can be supplied with
one or two Manual Control options. These can
operate the pilot valve(s) inside the module and
as such operate the actuator, when there is air
pressure available, but no control signal or power
supply.
8.1.1 Mounting Manual Control
1 To add a Manual Control, remove the plug(s)
in front of the module and turn in the Manual
Control.
- For normal operation the module should be
fitted with one Manual Control.
- For Double Acting with a Fail-in-Last-Position
function, two Manual Control can be fitted.

8.1.2 Manual Control operation
1 The Manual Control has a “Push & Lock”
function:
- To operate the Manual Control, use a screw
driver, push to activate and release to deactivate 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 Bettis
Q-Series 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 Bettis Q-Series 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).
Spring Return:
Top entry only.
Double Acting:
Bottom and/or top
entries.

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.
- 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 Speed control option
8.2.2 Adjusting Speed Control throttle(s):
(see figure 8.2).
The Bettis Q-Series 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
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.

11.1.2 Special conditions for safe use
• The material for the Control Module housing is
an aluminum alloy. When the unit is used in a
potentionally explosive atmosphere, requiring
ATEX equipment category 1 G, the unit must be
installed in such a way, that even in the event of
rare incidents, an ignition source due to impact
or friction between the enclosure and iron/steel
is prevented.
• Only non-combustible fluids may be used in the
pneumatic circuit.
Note: the surface temperature of the module has
been determined without a dust layer.
• Potential electrostatic charging hazard, clean
only with a damp cloth - danger of propagating
discharge.
• The apparatus shall be installed in such a way
that the risk from electrostatic discharges and
propagating brush discharges caused by rapid
flow of dust is avoided.
• Precaution shall be taken to avoid danger of
ignition due to electrostatic charges on the
marking plate of the enclosure.
