Installation, Operation and Maintenance Manual
DOC.IOM.Q.E Rev. C
• FieldQ Series actuators must be isolated both
pneumatically and electrically before (dis)
assembly.
• It is not permitted to connect a pressure vessel
with unreduced media to the FieldQ Series
pneumatic actuator.
• FieldQ Series actuators must not be connected to
an air supply greater than 8 bar g or 120 psig
• This manual does not provide instructions for
installations in hazardous areas.
• Installation, adjustment, putting into service, use,
assembly, disassembly and maintenance of the
pneumatic actuator must be done by qualified
personnel.
A1 Orientation (see fig� A1)
The FieldQ Series actuator is an integrated concept
for the automation of quarter turn valves, dampers
or other quarter turn applications. It can consists of
three basic parts:
1. Pneumatic actuator
2. Pneumatic Module or NAMUR Plate
3. Control Module

A2 Installation, operation and
maintenance reference documents
Before mounting, installing, commissioning or
(dis)assembling the actuator consult the following
documents:
- All chapters of this manual and
- Installation Guide of the supplied Control Module.
- For installation in hazardous area’s:
The applicable section of the Installation Guide, as
shipped with the Control Module.
- For Control Modules with bus communication
there may be an additional Reference Manual with
more detailed information.
(available from www.emerson.com/fieldq).
A3 Operating medium
• Air or inert gasses:
- Filtered to 50 micron (5 micron for QC54).
- Check the Installation Guide as shipped with the
module for the applicable air quality.
• Maximum pressure, 8 bar g / 120 psig

A5 Hazardous areas
Improper installation in a hazardous area can
cause an explosion.
• Assembly, disassembly and maintenance must be
done in safe area’s without a potential explosion
hazard.
• For information about installation in a hazardous
area, refer to the appropriate sections of the
Installation Guide, as shipped with the control
module.
A6 Warning ; Moving parts
Applying pressure to the actuator or
Applying a control signal to the Control
Module, may cause the actuator/valve
assembly to operate.
A7 Prevent moisture entering the
actuator
Condensation or moisture that enters the
actuator or the Control Module can damage these
components and can result in failures. Therefore:
• Try not to mount the actuator with the conduit
openings or the air entries, pointing upward.
• Ensure integrity of gaskets and o-rings.
• Install drip loops in conduit or cable. When
needed use Filter/Regulators with correct filter
specification.
• Seal all conduit openings whether used or not.
50µm
(QC54 = 5µm)
A8 Warehouse storage
• FieldQ Series Actuators and Control Modules
should be stored in a clean, dry warehouse, free
from excessive vibration and rapid temperature
changes.
• Actuators should not be stored on any floor
surface.
A9 On site storage
• FieldQ Series Actuators and Control Modules
should be stored in a clean, dry warehouse, free
from excessive vibration and rapid temperature
changes.
• Ensure all actuator covers are in place and
securely fastened.
• Replace plastic conduit plugs with appropriate
pipe plugs.
Failure to follow proper storage guidelines will void
warranty.
A10 Lifting instructions
• Use lifting equipement as required by national or
local legislation.

2�1 Before you start
In case of an air or electrical failure, it is important to know the behavior of the actuator.
Before mounting the actuator on a valve consult the following paragraph’s.
2�2 Failure modes
April 2017
2�2�1 Valve rotation
Valves are normally manufactured so that:
- the valve is closed after a clock wise rotation
(viewed from above).
closed
Fig. 2.2.1
- the valve is open after a counter clock wise
rotation (viewed from above).
open
2�2�2 Position after a failure
The position of the actuator after a failure depends on
the:
- Operating principles (see §2.3)
- Assembly code (see §2.4)
- Kind of failure

2�3�3 Position feedback
FieldQ Series patented, position sensing system
The FieldQ Series actuator (1) has a patented,
contactless position sensing system. This system
consists of a position probe (2) which is rides on a
special curve (4) in the pinion bottom.
The curve is shaped in such a way that the position
probe moves linearly and proportionally to the
rotation of the actuator pinion.
The linear movement of the position probe is used,
inside the control module (3) to operated the limit
switches.
WARNING:
Do not put the Control module in direct contact
with magnetic material. This can cause damage or
malfunction of the position feedback.
Installation of the FieldQ Series modules
For installation instructions of the modules see
chapter 4.
Installation Guides - Control modules
Each Control Module is shipped with an Installation
Guide, which contains more information on the
Fig. 2.3.5
pneumatic and electrical installation and operation
of the Module. Additionally, these Installation Guides
can be downloaded from.emerson.com/fieldq
