Initial setup
5.1
Initialization procedure
Initialization sets automatically the switch points for
the position feedback of the actuator (see §5.2)
Additionally, initialization checks if the actuator
and control module configuration match. This
procedure will detect the action type (Fail-Open,
Fail-Close or Fail in last position) and generate an
alert if there is a configuration issue.
This process is done automatically, by the module,
however, the user must start it and the unit must be
wired according chapter 4.
Digital communication is not required but power
supply is necessary (9V to 32V DC).
The initialization process can be started in one of
two ways:
WARNING
!
* During the initialization routine the actuator /
valve combination will cycle several times.
* Before initialization check whether the actuator and
valve have the same “Open” and “Closed” positions.
* Ensure that the valve stroke is not obstructed
before the initialization routine is started.

Troubleshooting
5.3.1 “Factory default settings”, using the
button board.
To set the control module to its factory default
settings, do the following;
1. Power must be connected according chapter 4
and the Status LED is either on or flashing.
2. Disconnect the power.
3. Press both reassignment
(OPEN and CLOSE) buttons.
4. Reconnect power.
5. Status LED goes on.
6. Release the reassignment
(OPEN and CLOSE) buttons.
7. Observe that the Status LED indicates that the
unit is in its “Init Default” state
(Flashing, see §5.2)
5.3.2 If auto initialization procedure has failed
(Status LED is flashing)
1. Check supply pressure
2. Check Actuator assembly code (see Installation
& Operation Manual Bettis Q-Series Valve
Actuator, DOC.IOM.Q.E)
3. Repeat the initialization procedure.
4. When the actuator does not move within 10
seconds, the auto initialization will fail.
5. To solve this either;
- Perform the “default setting” procedure
(see §5.3.1) and repeat the initialization
procedure (see §5.2), or
- Set the limit switch points individually by the
bus see Reference manual QC54,
DOC.RM.BQC54.E chapter 3.4.
Check functioning
To perform a function test, please see chapter 3 of
Reference manual QC54, DOC.RM.BQC54.E.

Manual Control options
(see figure 8.1)
For commissioning, emergency or maintenance
purposes, the Bettis Q-Series can be supplied with
one or two Manual Control options. These can operate
the spool 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.

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 clockwise.
-
-
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.

11.3 Safety instructions
!
WARNING
• Personal injury or property damage caused
by fire or explosion may occur if the module
is opened in any area which contains a
potentially explosive atmosphere or has been
classified as hazardous.
• The material for the Control Module housing
is an aluminium alloy. When the unit is used
in a potentiality explosive atmosphere,
requiring EPL Ga, 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.
• For applications in explosive atmospheres
caused by air/dust mixtures and where
equipment with EPL Da is required, the
surface temperature has been determined
for a dust layer with a thickness of
5 mm maximum.
• 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.
• Substitution of electronics cartridge, switch
cartridge, pilot valve cartridge, pneumatic
cartridge, enclosure and seals must be with
parts from Emerson else the suitability for
Division 2 will be impaired.

and 2 with flammable gases and vapours
with apparatus groups IIA, IIB & IIC and with
temperature classes T1, T2, T3, T4.
The equipment may be used in zones 20, 21 &
22 with flammable dusts, fibres and flyings in
groups IIIA, IIIB and IIIC, with a layer autoignition temperature of not less than 75 K
above the maximum surface temperature
marked in the dust coding.
Installation, adjustment, putting into service,
use, assembly, disassembly and maintenance
or repair, shall be carried out in accordance
with the applicable code of practice by
suitably-trained personnel.
There are no special checking or maintenance
conditions other than a periodic check.
With regard to explosion safety, it is not
necessary to check for correct operation.
If the equipment is likely to come into contact
with aggressive substances, e.g. acidic liquids
or gases that may attack metals or solvents
that may affect polymeric materials, then it is
the responsibility of the user to take
suitable precautions that prevent it from
being adversely affected thus ensuring that
the type of protection is not compromised.

12 FISCO Concept
The QC54 module is suitable for use in a FISCO system in accordance with IEC 60079-11 : 2012 for use in
Zone 1 and 2 locations.
12.1 Fieldbus Intrinsically Safe Concept
The FISCO Concept allows the interconnection of intrinsically safe apparatus to associated apparatus not
specifically examined in such combination.
The criterion for such interconnection is that the voltage (Ui or Vmax), the current (Ii or Imax), and the
power (Pi), which intrinsically safe field devices can receive and remain intrinsically safe, considering faults,
must be equal to or greater than the voltage (Uo, Voc), the current (Io, Isc) and the power (Po) levels which
can be delivered by the associated power supply device considering faults and applicable safety factors.
In addition, the maximum unprotected capacitance (Ci) and inductance (Li) of each apparatus (other than
the terminators) connected to the Fieldbus must be less than or equal to 5 nF and 10 µH respectively.
In each I.S. Fieldbus segment only one active device, normally the associated apparatus, is allowed to
provide the necessary energy for the Fieldbus system. The voltage (Uo or Voc) of the associated apparatus,
used to supply the bus, has to be limited to the range of 14VDC to 24VDC.
All other equipment connected to the bus cable has to be passive, meaning that the apparatus is not
allowed to provide energy to the system, except to a leakage current of 50 µA for each connected device.
Separately powered equipment needs a galvanic isolation to insure that the intrinsically safe Fieldbus circuit
remains passive.
12.2 Cable parameters
The cable used to interconnect the devices needs to comply with the following parameters:
Loop resistance Rc:
15 ...150
Ohm/Km
Inductance per unit length Lc:
0.4…1
mH/km
Capacitance per unit length Cc:
80 ...200
nF/km
Cc = Cc line/line + 0.5 Cc line/screen, if both lines are floating or
Cc= Cc line/line + Cc line/screen, if the screen is connected to one line
Length of spur Cable:
max. 60
m
Length of trunk cable:
max. 1
Km
m (T-box must only contain terminal connections
Length of splice:
max. 1
with no energy storage capability)
When the cable complies with IEC 60079-11, no further consideration of cable parameters is necessary.
The cable parameters may be determined in accordance with Annex C of IEC 60079-14.
12.3 Terminators
At both ends of the trunk cable, an approved line terminator with the following parameters is suitable:
-
R
C
=
=
90 ...102Ohm
0 ...2.2 µF
Note: IEC 61158-2 requires an operational capacitance value of 0,8 µF to 1,2 µF.
The number of passive devices connected to the bus segment is not limited due to I.S. reasons. If the above
rules respected, up to a total length of 1000m (sum of trunk cable and all spur cables), the inductance and
capacitance of the cable will not impair the intrinsic safety of the installation.
