1 Applicable Control Modules
QC40 - AS-Interface Weather proof IP66/
NEMA4X
QC40 - AS-Interface Non-Incendive
or Non Sparking
Note:
These variations 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.
The enclosures have a IP66 or NEMA 4X, ingress
protected rating.
2 Before starting
* Actuator must be isolated both pneumatically
and electrically before any (dis)assembly
is begun.
* Hazards related to the control of external
processes under measurement, are beyond
the scope of of the content described in
this document.
* Installation, adjustment, putting into service,
use, assembly, disassembly and maintenance
of the control module must be done by
qualified personnel.
* Do not install, operate, or maintain a Q series
control module without being fully trained and
qualified in valve, actuator, and accessory
installation, operation, and maintenance.
* To avoid personal injury or property damage,
it is important to carefully read, understand,
and follow all of the contents of this manual,
including all safety cautions and warnings.
* 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.BQ.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.QC4.MTI.1,
as shipped with the module.
* If you have any questions regarding these
instructions, contact your Emerson sales office
before proceeding as shipped with the module.

2.1 Mechanical alignment and mounting of
the control module
The control module is equipped with an alignmentedge on top of the module.
This allows easy alignment and mounting of the
control module on to the actuator housing.
Procedure: (see figure 2.3)
1. First take care that both mating faces from the
actuator and control module are clean and free
of dirt.
2. Check if the module has the required function
3. Remove the transparent film from the
control module.
4. Ensure seals are placed correctly.
5. Level the screws with the surface.
6. Place the alignment-edge (1) of the control
module at the top of the pneumatic interface.
7. Flip the module down taking care that the IPT
Probe (2) on the actuator fits in the mating hole
on the control module and loosely place
the screws.
8. Tighten screws according force in sequence.
Tightening moments
The Control Module should be fastened by using an
Allen key and applying the following
tightening moments:
- Allen Key: No 5
- Torque: 6.1 to 6.6 Nm (54 - 58.4 In.lbs)

IMPORTANT
1 The actuator/valve combination can move
after connecting the air supply.
2 Ensure that the QC40 control modules are
mounted properly to the actuator to achieve
good functioning and the required ingress
protection, before connecting the air supply.
3 Check that the maximum supply pressure
P
= 8bar/116Psi
max
4 Be sure that the minimum required supply
pressure for the application is available at
the actuator.
5 Take appropriate measures to prevent
condensation or moisture to entering the
actuator or the control module. Condensation
or moisture can damage these components
and can result in failures.
6 The exhaust ports Ra and Rb on the module
(see figure 3.1) are shipped from the factory
with transport protection.
* If ingress protection IP66 or NEMA 4X is
required, appropriate connections must be
used in exhaust ports Ra & Rb.
3.1 Operating media :
* Air or inert gasses.
* Air filtered at 50μm.
* Dew point 10 K below operating temperature.
* For subzero applications take
appropriate measures.
3.2 Single acting (spring return) or Double
acting actuator :
1 Remove the transport sticker from the
air supply (Ps).
2 Connect air supply to port (Ps).

WARNING:
* If the Control Module is used in a manner not
specified by the manufacturer, the protection
provided by the equipment may be impaired.
* If required, mount earth wire (1) between top
(2) and bottom (3) ring of earth wire
connection (see figure 4.1).
4.1 Electrical data for hazardous area
executions
Please check chapter 10 for electrical data and
instructions in case an “Non Incendive/Non Sparking”
Control Module is used in hazardous locations
(Zone 2 or Class I Div.2).
* The current restricted power supply meets NEC
Class 2, as described by the National Electrical
Code® (ANSI/NFPA 70 (NEC®))
* In case the Control module is used in Hazardous
locations, check the Control Drawings as per
chapter 10 for the applicable temperature range.

4.2 Procedure
1 Remove Control Module cover (see figure 4.2).
2 Guide the cable(s) through the electrical
entry(ies).
- Use and mount cable glands as required by
national or local legislation.
- When IP66/NEMA4X ingress protection is
required, the electrical entries must be fitted
with glands rated IP66/NEMA4X or higher.
3 Make the electrical connections as shown in
figure 4.3.
- For hazardous area connections, see the
instructions in chapter 10
- Quick connectors, as shown below, are allowed
to be used only for non-explosion safety
product application
4 Mount the function module cover to the housing
(see figure 4.2) or continue with chapter 5. Take
care that the cover seal is in place to comply to
dust and water tightness according to IP66 /
NEMA4X.
