Brief User Guide
This is a quick guide to connecting the instrument for the conven-
ience of personnel who are familiar with this type of product.
More comprehensive instructions are contained later in this
manual:
1. Connect a clean air supply of about 2.0 bar (30 psig for the
3-15 psig output model, or 2.4 bar (35 psig) for the 6-30 psig
output model) to the IN port (1/4" NPT).
2. Connect a pressure gauge or actuator to the OUT port.
DO NOT use PTFE tape or similar to seal the
ports. Use a minimum of soft setting anaerobic
compound, e.g. Loctite Hydraulic Seal 542.
3. Unscrew the lid to obtain access to the terminals.
The cable will need to be sealed by an approved
gland for explosion-proof installation.
The second un-used conduit entry must be
sealed with an explosion-proof blanking plug.
4. Connect a 4-20mA current source, either through the Jack-
Plug source or Terminal connections. Ensure that it can
supply at least 6.5V at 20mA. Check for correct polarity.
DO NOT use a voltage source; it will irreversibly dam-
age the converter.
5. Switch on the air supply and current source and allow a
few seconds stabilisation time. Adjust span and zero via the
trimpots if necessary.
If the instrument fails to operate refer to the Simple Functional
Checks�
General Description
These converters are precision electronic pressure controllers
designed for continuous process control applications. The units
operate a closed loop system incorporating a feedback sensor
ensuring long-term stability and high accuracy performance, with
‘fail-safe’ operation, i.e. the output falls to a low pressure upon
failure of the loop current.
These instruments combine substantial flow capacity, with the
ability to give precise control into closed volume ‘dead end’
applications�
The instrument has been designed to withstand the rigours of
industrial environments; such as shock, vibration and positional
effects. As with any other precision instrument dropping the
unit onto a hard surface may result in shifts in calibration or
possibly permanent damage. The unit may be mounted directly
upon a control valve. A mounting bracket is provided for surface
mounting, or the instrument may be fixed directly to rigid
pipework.
The electronics are enclosed within a watertight housing, which
is suitable for outdoor use if a suitable cable gland is used. The
lid should be firmly tightened, the use of a tool for this purpose is
not recommended�

To meet the EMC specifications, screened cable should be
used for installation. The cable screen should be connected to
the internal earth bonding point of the I/P. An earth strap should
also be connected from the external earth bonding point of
the I/P to a common earth point. The cable screen should not
be connected at the signal source when used in Intrinsically
Safe (IS) environments. The I/P has been thoroughly tested in
accordance with:
Electromagnetic compatibility (EMC)
Generic Standards – Immunity for industrial environments
Electromagnetic compatibility (EMC)
Generic Emissions Standard – Industrial environment
Please consult wiring diagram for further information. The results
obtained from these tests show that with the screen arrangement
shown in the installation diagram, the typical sustained output
pressure shift is <+/-5% full scale. Consult supplier for further
details�
Instrument Mounting
The converter can be mounted directly onto a valve, onto any
suitable flat surface, or onto 2” (50mm) pipe. Dimensional details:
Figure 2
These converters will operate in any position, with slight re-
calibration adjustments, normal operation is in the upright
position, i.e. with the screwed lid horizontal. The unit is weather
resistant when the lid is removed for connection or calibration,
but should not be left uncovered during operation or for extended
periods of time. They are unaffected by shock and vibration, but
severe vibration environments are best avoided.
The instruments are protected against environmental effects, to
a level of Type 4X (IP66). Sensible positioning should be used if
the local environment is severe.
Temperature compensation is designed into these converters
which will operate over a range from –40° to +85°C (-40° to
+185°F). Maximum life is obtained if extreme temperature cycling
is avoided. In extreme direct sunlight, sun-shading is advised.
The pneumatic exhaust and the bleed are routed through the
baffles. The baffles must not be blocked with paint and/or plastic
sheeting etc�
Captured Bleed Version
The baffles and the baffle cover are fitted to maintain the adequate
Ingress Protection (IP) rating of the instrument. Removal of these
protective parts will invalidate the IP and the NEMA 4X rating of
the instrument�
For captured bleed installation, remove the baffle cover and
unscrew both the baffles, fit 1/8" NPT fittings to two separate
lengths of pipes, to exhaust and bleed gas to a safe area
installation�
Vented gas from the enclosure through bleed port must not
be re-circulated and introduced back into the process stream.
Exhaust port installation must not have any restriction to create
backpressure to cause instrument to malfunction. Instrument
installation for captured bleed version must be under the
installer’s discretion.
Note: Exhaust Port is nearer the conduit entry (LH side)
Enclosure Bleed Port is on the RH side. (See Figure 3.)
Figure 3
Pneumatic Installation
These instruments are recommended for use with clean, dry, oil
free instrument grade air to BS.6739 or ISA-7.0.01-1996.
Dew Point: At least 10°C (18°F) below (-40°C) minimum
anticipated ambient temperature.
Dust: Filtered to below 50 microns.
Oil Content: Not to exceed 1ppm mass.
The instrument is factory calibrated with a supply pressure of 30
psig (2 bar) ±10%. Operation is possible at any pressure between
18 and 150 psig (1.3 to 10 bar), though recalibration may be
necessary towards these limits to maintain specified accuracy.
The inlet and outlet ports are threaded 1/4" NPT female and
suitable fittings should be used. For most installations 1/4" (6mm)
pipe will be adequate. If a large actuator, high flow rates or long
pipework is necessary then a larger diameter should be used.
Plastic tubing, e.g. Nylon is preferable where circumstances
permit, since it is normally very clean internally. In all cases,
purge the supply pipework before connection to the converter.
Two gauge ports are provided to facilitate direct mounting of
a pressure gauge. To use one of these ports remove the plug
(using a 1/4" or 3/16" Hexagon Key) in a de-pressurized state,
and connect the gauge. The ports are threaded 1/4" NPT at the
back of the unit and 1/8" NPT at the front.

Under no circumstances should PTFE tape be used
for sealing the ttings as this tends to shred small
particles which may nd their way into the instrument
causing malfunctions.
The use of a soft setting anaerobic hydraulic seal is recommended,
(e.g. Loctite Hydraulic Seal 542). Follow the manufacturers
recommendations�
Do not use an excessive amount as this will not set
and could nd its way into the instrument.
If the air supply is not of adequate quality, the device performance
can be affected. Adequate quality can normally be achieved by
the use of air filter regulators.
Electrical Installation
The electrical connections should be made as shown in the
dimensional drawing Figure 1. The instrument is protected
against reverse polarity to –100mA, no operation is possible in
this condition�
The Model 4411 approximates a constant voltage load of 6.5
volts across the loop terminals, therefore it is essential that the
loop controller be capable of providing a constant current in the
range 4-20mA with an output voltage of at least 6.5 volts.
Voltage output controllers (e.g. variable voltage power
supplies) are entirely unsuitable for the Model 4411
and could severely damage the electronic circuits.
Important Note
The control electronics of the Model 4411 incorporate
precision electronics. The calibration of the unit may be
affected by very high voltage spikes. Consequently, in
environments where static electricity may be present ESD
precautions should be used.
Wiring And Cable Entry
These instruments must be installed in accordance
with local and national codes of practice, especially for
hazardous area installations. The instruments are fully
isolated from ground and therefore grounding is un-
necessary for functional purposes. However, ground-
ing may be necessary to conform to installation codes.
Note: It is strongly recommended that shielded cable or a
grounded conduit be used to achieve maximum RFI immunity,
if the installation has any risk of electromagnetic interference.
Conduit Entry
The instrument has twin conduit entry threaded 1/2" NPT. For
explosion proof installation, a sealed conduit gland conforming to
explosion-proof specifications must be used. A ground terminal
is provided both internally and externally and should be used if
ground continuity is essential.
The unit is supplied with plastic blanking plugs, which
must be removed before operation/calibration and re-
placed with a blanking plug conforming to the hazard-
ous area certication rating applicable.
Calibration
The instruments are designed for continuous operation without
the necessity for routine overhaul, with continuous monitoring,
adequate precautions and replacement of the filter no longer
than every 5 years.
The most common source of failure for pneumatic instrumentation
has been found to be inadequate air quality, allowing
contaminants to block internal orifices. Air filtering is included
within the instrument but cannot cope with sustained poor air
quality, which may ultimately lead to failure.
The recommendations in the Pneumatic Installation section
should be rigorously observed.
Note: These instruments are factory calibrated at a supply
pressure of 30psig (2 bar).
The instrument cover must be unscrewed to obtain access to
the trimpots�
Do not remove the instrument cover in a potentially
explosive atmosphere when the instrument is powered.
An accurate current source of 4-20mA and pressure gauge are
required. These should be of good quality with an accuracy of
0.1% or better. The current source should be checked to ensure
that it provides at least 6.5V at 20mA output compliance.
• Connect the instrument as described in the installation
section or the test-jack section below.
• Remove the instrument cover to gain access to the trimpots
and jack-socket.
• Set the current to 4.00mA – the instrument outlet should be
3.00+/-0.05psig (0.200+/-0.003 bar). Adjust the Zero trimpot
if necessary.
• For 6-30 psig output, the output pressure should be set to
6.00 ±.05 psig (0.400 ± .003 bar). Adjust trimpot as necessary.
• Set the current source to 20.00mA – the instrument outlet
should be 15.00 +/-0.05psig (1.00+/-0.003 bar). Adjust the
Span trimpot if necessary.
• For 6-30 psig output, the output pressure should be set to
30.00 ±.05 psig (2.00 ± .003 bar). Adjust trimpot as necessary.
If either Span or Zero controls are adjusted it may be necessary
to repeat the above steps until both ends are within the calibration
limits�
Alternatively the Jack Plug can be connected to calibrate and
test the unit. The Jack Plug can be either set-up for Monitoring or
Calibration/Operation set-up.

Calibration with the Test Jack:
Connect pin 1 of the Jack Plug to the positive (+) lead of the
current calibrator and pin 3 of the Jack Plug to the negative (-)
lead of the current calibrator and then insert the Jack Plug into the
Test Jack. The current calibrator is now the input signal source.
Calibrate as stated above. Removing the Jack Plug will return
operation of the unit back over to the original current source.
Figure 4
Monitoring with the Test Jack:
Connect pin 1 of the Jack Plug to the negative (-) lead of the
ammeter and pin 2 of the Jack Plug to the positive (+) lead of
the ammeter. Insert the Jack Plug into the Test Jack and use the
ammeter to monitor the input current loop�
Tight Shut-Off Adjustment
Instructions
Figure 5
The Tight Shut-Off potentiometer can be adjusted to set the zero
point at which the instrument ‘shuts off’.
For Example:
Tight shut-off is deactivated in the factory.
Figure 6
Setting of shut-off point:
1. With the instrument under test connected to the required
supply pressure and load ports, apply a demand current
signal of that value at which shut-off is required.
2. If the output pressure is >start-up pressure (~0psi), adjust
potentiometer slowly clockwise until the output pressure
falls to zero. Do not turn the pot beyond this point. The shut-
off point is now set.
Shut-off point check:
Increase the input signal by approximately 0.5mA (e.g. to 3.8mA)
the output pressure will rise above 0psi. Reset the input signal to
the required shut off point (e.g. 3.3mA) and the output pressure
will fall to zero.
Simple Functional Checks
Apply a 4-20mA signal and an air supply of 30psig and observe
the output on a pressure gauge. It should control smoothly. The
Test Jack can also be connected as a monitor measure.

1. For operation reasons, it may be necessary to connect the
screen of the cable to the enclosure of the equipment in
the hazardous area. If this is the case, then the equipment
shall be installed in accordance with EN 60078-14:2014
(specifically clause 16.2.2.3 and 16.2.4), typically using a
galvanically-isolated interface with no other connection to
Earth apart from via the enclosure of the equipment.
2. The enclosure is made from light metal which could cause
ignition due to impact and friction. This shall be taken into
consideration when the apparatus is installed in location that
specifically requires equipment protection level Ga.
3. Under certain extreme circumstances, the non-metallic
parts incorporated in the enclosure of this equipment may
generate an ignition-capable level of electrostatic charge.
Therefore, when it is used for applications that specially
require equipment protection level Ga, the equipment shall
not be installed in a location where the external conditions
are conductive to the build-up of electrostatic charge on
such surfaces. Additionally, the equipment shall only be
cleaned with a damp cloth.
4. The option for the air vented from the enclosure to be re-
circulated and introduced back into the process stream shall
not be used when the equipment is installed in locations that
specifically require equipment protection level Ga for group
II category 1G or 1D for group III category 1D equipment.
