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 Posi-
tion 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
FieldQ 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.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: 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 QC54 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
max
= 8bar/116Psi
4 Be sure that the minimum required supply
pressure for the application is available at the
actuator.
5 Take appropriate measures to prevent conden-
sation 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 re-
quired, appropriate connections must be used
in exhaust ports Ra & Rb.
3.1 Operating media :
* Air or inert gasses.
* Air filtered at 5 micron.
* 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
* Do not put the Control module and the Pneu-
matic module in direct contact with magnetic
material. This can cause damage or malfunction of the position feedback.
* 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).
Table 4.1 Electrical data QC54 - FF
Voltage range * 9 to 32 volts
Maximum current 18 mA

(-4°F to +122°F)
Humidity 0 to 85% at 25°C(+77°F)
derate to 50% above 40°C
(104°F) (non-condensing).
Altitude Operating full power available
up to 2000 meter (6000 feet).
Use In- and outdoor.
* In case the Control module is used in Hazardous
locations, check the chapters 10, 11 or 12 for
detailed instructions.

4.1 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 IP65/NEMA4X ingress protection is
required, the electrical entries must be fitted
with glands rated IP65/NEMA4X or higher.
- Apply minimum thread counts:
For NPT, at least 5 full threads
For Metric, at least 8 full threads for
Group A/B and 5 full threads of Group C/D
3. Connect the FOUNDATION™ Fieldbus signal
to the applicable terminals (see figure 4.3).
- For 7/8” or M12 quick connector pinout,
see figure 4.3 and 4.4.
- For hazardous area connections, see the
wiring instructions in 11.5 and 11.6
4. Mount the function module cover to the hous-
ing (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.
