5 Limit switch setting
Fig. 5.1 Adjustable range and factory settings
If required the mechanical stroke and the limit
switch setting can be re-adjusted.
- For mechanical stroke adjustment please see
document DOC.IOM.Q.E, available from
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.
5.1 Factory settings
Mechanical stroke : 90°±0.5° (Actuator setting)
Switch points : ± 15° before each end of
stroke (open and closed
position, see fig 5.1).
Adjustable range : See chapter 4.2 for the
applicable switch type.
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 g 5.2)
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.
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).
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).
Fig. 5.2 Working principles Switch Operating Mechanism
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).
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.
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.
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.

5.3 Re-adjustment of switch points
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.
To set and detect the switch point, use a multi
meter, connected to the switch terminals, to
measure
a resistance change as applicable per switch type
(see applicable wiring diagram in chapter 4.2). For
the proximity switches, you can use a proximity
switch tester.
Procedure (see g 5.3):
1. Remove cover (15) and loosen the screw (11) of
the shield (12) and turn the shield down.
Closed Position:
2. Move the actuator/valve assembly to the closed
position by removing the control signal from
pilot valve terminal 8 and 9 (see § 4.1).
3. Turn top screw (10) counter clock wise (do not
force the adjustment screw) until the switch
trips to the “off state” (no signal).
4. Turn top screw (10) clock wise (do not force the
adjustment screw) until the switch trips to the
“on state”. This position represents the actual,
mechanical “closed” position of the valve.
5. Turn the screw minimal a 1/2 turn clock wise.
The “closed” position switch point is now set.
Open Position:
6. Move the actuator to the open position by
applying the applicable voltage to pilot valve
terminal 8 and 9 (see § 4.1).
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 rep-
resents 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.

6 Trouble shooting
6.1 The “Open” and “Closed” position
feedback signals are reversed from the
actual valve positions.
1 Check if the actuator is correctly mounted to the
valve.
Before mounting the actuator on the valve, the
actuator and the valve should have the same
“open” or ‘closed” position (see Installation
& Operation Manual Bettis Q-Series Valve
Actuator DOC.IOM.Q.E).
2 Some valves may be operated in such a way that
they are:
- “Open” after a clock wise rotation and
- “Closed” after a clock wise rotation.
3 Please see § 5.2 for setting the “Open” and
“Closed” position feedback signals
6.2 The actuator does not give (good) position
feedback signals.
1 Check if the actuator is correctly mounted to the
valve.
2 Re-adjust the limit switch setting as per chapter
5.3
6.3 Factory setting of the switch points.
IMPORTANT
The procedure below assumes:
- That the actuator / valve assembly is closed
after a clock wise rotation (see also § 5.1).
- The control module is pneumatically and
electrically connected according chapter 3 and 4.
This procedure sets the switch point settings of the
switches, back to the factory settings (±15° before
each end of stroke), assuming a mechanical stroke
of 90°±0.5° of the actuator.
To set and detect the switch point, use a multi me-
ter, connected to the switch terminals, to measure a
resistance change as applicable per switch type (see
applicable wiring diagram in chapter 4.2).
For the proximity switches, you can use a proximity
switch tester.

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.

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 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 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).
8.2 Speed control option
(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

11 Intrinsically Safe Electrical connections
11.1.1 ATEX Intended use
The Control Module QC44.xP1Nxx1 of the Bettis
Q-Series pneumatic actuator is Group II category 1
equipment and intended for use in areas in which
explosive atmospheres caused by mixtures of air
and gases, vapours, mists or by air/dusts are likely
to occur.
The pneumatic actuator part, together with the
pneumatic Module part of the Bettis Q-Series pneu-
matic actuators is a Group II category 2 equipment
and intended for use in areas in which explosive
atmospheres caused by mixtures of air and gases,
vapours, mists or by air/dusts are likely to occur.
Therefore it may be used in (ATEX) classified Zones
1, 2 (Gasses) and/or 21, 22 (Dust).
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.
