2.1 Unpacking
When moving the transmitter to the installation site, keep it in its original packaging. Then, unpack
the transmitter there to avoid damage on the way.
2.2 Models and Specifications Check
The model name and specifications are indicated on the nameplate to the case. Please check your
specification and wanted model.
2.3 Storage
The following precautions must be observed when storing the instrument, especially for a long period.
(1) Select a storage area that meets the following conditions:
(a) It is not exposed to rain or water.
(b) It suffers minimum vibration and shock.
(c) If possible, it is preferable at normal temperature and humidity (approx. 25°C, 65% RH).
However, it has an ambient temperature and relative humidity within the following ranges.
● Ambient Temperature: -40 ~ 85°C (without LCD module)
-30 ~ 80°C (with LCD module)
* General Use -20 ~ 60°C (CSA Explosionproof)
● Relative Humidity: 5% ~ 98% RH (at 40°C)
(2) When storing the transmitter, repack it as nearly as possible to the way it was packed when
delivered from the factory.
(3) If storing a transmitter that has been used, thoroughly clean diaphragm surfaces (the pressure-
detector sections) of the diaphragm seals, so that no measured fluid remains on them. In addition,
make sure before storing that the pressure-detector and transmitter assemblies are securely
mounted.
2.4 Selecting the Installation Locations
The transmitter is designed to withstand severe environmental conditions. However, to ensure stable
and accurate operation for many years, the following precautions must be observed when selecting an
installation location.
(1) Ambient Temperature
Avoid locations subject to wide temperature variations or a significant temperature gradient. If the
location is exposed to radiant heat from plant equipment, provide adequate insulation or
ventilation.
(2) Ambient Atmosphere
Avoid installing the transmitter in a corrosive atmosphere. If the transmitter must be installed in a
corrosive atmosphere, there must be adequate ventilation as well as measures to prevent intrusion
or stagnation of rainwater in conduits. Moreover, there should be appropriate ventilation
preventing corrosion by rain gathered on conduit.
(3) Shock and Vibration
Select an installation site suffering minimum shock and vibration (although the transmitter is
designed to be relatively resistant to shock and vibration)
(4) Installation of Explosion-protected Transmitters
Explosion-protected transmitters can be installed in hazardous areas according to the gas types
for which they are certified.
Page 14
APT3500 Smart Pressure Transmitter Operation Manual M3500-EO1G
12 DUON System Co., Ltd.
(5) Select a place that transmitter maintenance is very easy.
2.5 Calibration on Spot after Installation
(1) Sensor Zero Trim should be done after transmitter is installed on spot, because zero point is not
accurate as to mounting status.
(2) For Sensor Zero Trim, make differential pressure of transmitter for zero in advance. Then, make
Sensor Zero Trim after pressure is sufficiently stabilized (after approximately 10 seconds).
(3) There are two ways for making differential pressure for zero. One is to apply zero differential
pressure (making same pressure both high and low side pressure). The other is to close Hign and
Low side of stop valve of 3 valve manifold and to open its equalizing valve.
(4) Sensor Zero Trimming is to use HHT (ACONF312 or 275/375/475 HART Communicator), PC or PDA
configurator, and to use Zero/Span button. Make sure all details on this manual.
(5) Refer to On-line Operation for configuring another parameters except Sensor Zero Trim
2.6 Pressure Connections
The following precautions must be observed in order to safely operate the transmitter under pressure.
(1) Never apply a pressure higher than the specified maximum working pressure.
(2) Confirm the option of pressure connection of transmitter. Necessarily use standardized and quality-
approved parts.
(3) In case of being needed by hard circumstances and regulations, there should be seal equipment
for leakage.
2.7 Waterproofing of Cable Conduit Connections
Apply a non-hardening sealant (silicone or tape, etc.) to the threads to waterproof the transmitter
cable conduit connections.
2.8 Restrictions on Use of Radio Transceivers
▲ Warning
◈ Instrument installed in the process is under presure. Never loosen or tighten the flange bolts as it may
cause dangerous spouting of process fluid.
◈ If the accumulated process fluid may be toxic or otherwise harmful, take approriate care to avoid contack
with the body of inhalation of vapors even after dismounting the instrument from process line for
maintenance.

2.9 Insulation Resistance Test and Dielectric Strength Test
Since the transmitter has undergone insulation resistance and dielectric strength tests at the factory
before shipment, normally these tests are not required. However, if required, observe the following
precautions in the test procedures.
(1) Do not perform such tests more frequently than is absolutely necessary. Even test voltages that
do not cause visible damage to the insulation may degrade the insulation and reduce safety margins.
(2) Never apply a voltage exceeding 500 Vdc (100 Vdc with an internal lightening protector) for
the insulation resistance test, nor a voltage exceeding 500V AC (100V AC with an internal lighting
protector) for the dielectric strength test.
(3) Before conducting these tests, disconnect all signal lines from the transmitter terminals.
Perform the tests in the following procedure.
(4) Insulation Resistance test
(a) Short-circuit the + and - SUPPLY terminals in the terminal box.
(b) Turn OFF the insulation tester. Then connect the insulation tester plus (+) lead wire to the
shorted SUPPLY terminals and the minus (-) lead wire to the grounding terminal.
(c) Turn ON the insulation tester power and measure the insulation resistance. The voltage
should be applied short as possible to verify that insulation resistance is at least 20M.
(d) After completing the test and being very careful not to touch exposed conductors disconnect
the insulation tester and connect a 100k resister between the grounding terminal and the short-
circuiting SUPPLY terminals. Leave this resistor connected at least three second to discharge any static
potential. Do not touch the terminal while it is discharging.
(5) Dielectric Strength Test
(a) Short-circuit the + and - SUPPLY terminals in the terminal box.
(b) Turn OFF the dielectric strength tester. Then connect the tester between the shorted SUPPLY
terminal and the grounding terminal. Be sure to connect the grounding lead of the dielectric strength
tester to the ground terminal.
▲ Warning
◈ Although the transmitter has been designed to resist high frequency electrical noise, if a radio transeiver is
used near the transmitter of its external wiring, the transmitter may be affected by high frequency noise
pickup. To test for such effects, bring the transceiver in use slowly from a distance of several meters from
the transmitter, and observe the measurement loop for noise effects. Thereafter, always use the
transceiver outside the area affected by noise.
Page 16
APT3500 Smart Pressure Transmitter Operation Manual M3500-EO1G
14 DUON System Co., Ltd.
(c) Set the current limit on the dielectric strength tester to 10mA, then turn ON the power and
gradually increase the tester voltage from '0' to the specified voltage.
(d) When the specified voltage is reached, hold it for one minute.
(e) After completing this test, slowly decrease the voltage to avoid any voltage surges.

3.8 Shop Commissioning using HHT
Commissioning consists of testing the transmitter, testing the loop, and verifying transmitter
configuration data. APT-3100 Pressure Transmitter may be commissioned using HHT of HART
supported either before of after installation.
▲ If you connect "TEST" pin, it's not communicated. If it doesn't exposed electronics circuits after
install, you must connect all Jumper of transmitter in the shop commissioning level. Analog output of
transmitter is 4~20 mA, thus it requires Power Supply at 24V (12 V ~ 45 Vdc) and Ampere meter for
measuring output current. You must connect 250~550 ohm resistor in Power Loop for HART
Communication and HHT or PC Configurator.
1) HTT(Hand Held Terminal) or PC Configurator may connected at any termination point in the
signal loop
2) HART Communication requires a loop resistance between 250~550 ohm @ 24Vdc.
3) Transmitter operates on 12 to 45.0 Vdc Transmitter terminal voltage.

4.5 General Considerations
This transmitter uses the capacitive pressure sensor. If it changes the pressure sensor, capacitive
pressure is changed minutely.
It transfer electrical signal minutely to 4~20mA analog signal. Thus mount the transmitter close to the
process and use a minimum of piping to achieve best accuracy. However keep in mind the need for
easy access, safety of personnel, practical field calibration, and a suitable transmitter environment.
In general, install the transmitter so as to minimize vibration, shock, and temperature fluctuations.
4.6. Electrical Considerations (Power Supply)
The transmitter housing composes of two parts. One side is electronics circuit, and other side is
Terminal Block. Terminal Block side is transmitter's frontside and is indicated " Field Terminal" in
transmitter housing external. Open this side's housing cover, there is Terminal Block in housing inside.
Consider to this Terminal Block polarity, connect to Transmitter's Power Supply. Configurator supported
HART connects to "COMM" pin in Power Supply downside. In the field Indicator connects to "TEST"
pin.
4.6.1 Power Supply
In the transmitter's power supply Input Current Voltage is currently DC voltage between DC 12
volt ~ 45 volt and power supply's ripple is not up to 2%. Loop resistance means all resistor sums
in loop.
In case of using Intrinsic Safety Barrier, same includes resistor of barrier.
Max. Loop Resistance [Ω] = (E-12) [vdc] / 0.022 [mA]
Here, loop resistance is preferable at 250 ~ 550Ω (24 Vdc) for the HART communication.
4.7. Wiring
4.7.1 Caution of Wiring
(1) Install cable in the far from electrical noise resources like capacitive transformer, motors
power supply as soon as possible.
(2) Before wiring put out electrical lead connect cap.
(3) All screw-lined portions paste suture for waterproof. (It promotes the silicon type that is not
hardened.)
(4) Don't lead signal line to power line in same duct for no received noise signal.
(5) The explosion-proof transmitter in order to maintain the explosion-proof quality of the
corresponding transmitter effectively follows in the demand explosion-proof specification that
is provided and must be lead.
4.7.2 Selecting the Wiring Materials
(1) Use over 600V PVC shielded wire or standard lead line of same class or cable. (In order to
ensure proper communication use 24 AWG or lager wire, and do not exceed 1500 meters.)
(2) Use the shielded wire in electrical noise effected area.

39 DUON System Co., Ltd.
COM M TESTCOMM TEST
(3) At the higher or lower temperature area than ambient temperature it uses the wire or the
cable that is suitable like that temperature.
(4) You have to use suitable wire, cable in environment like oil, solvent, toxic gas or liquid.
(5) Terminal process of lead line must use to not soldered terminal lug. Recommend isolating lead
end terminal using contract tube.
4.7.3 Connections of External Wiring to Transmitter Terminal Box
Wiring method is following this.
▲ (1) Open the housing cover indicated "FIELD TERMINAL". In explosion environment when circuit
is powered on, don't open the covers.
▲ (2) Connect the power supply in the terminal indicated "+PWR"(left terminal) and "-" power
supply in the central terminal. Don't connect "+" power supply in "+" terminal of the point
indicated "TEST". It will be damage to test diode used to connecting TEST terminal.
(3) Seal and close the non-using Conduit Connection Part for severe humidity and explosion on
the terminal box of housing.
(4) Transmitter power is supplied to Signal Wiring. So, don't install near to Signal Wiring with
Power Wiring or near to Power Apparatus. In case of ground signal, ground the signal loop's
one side and other side is not grounded. Promote to ground "-" side of power.
(5) For the better adjustment completely turn Screw terminal.
(6) Again close the transmitter cover. Specially in case of using in explosion area, you must to
satisfy requirement about explosion.
[Note]
Don't supply high voltage (AC power) in transmitter leads. It can be caused damages to
transmitter.
(7) You have to connect 250~600 W Loop Resistor in Current Loop(between Power Supply and
Transmitter) for HART Communication HART. Following Figure 4-2 about conection of Current
Loop.

4.8.1 Mounting
To use the cadence carrier from the environment where the vibration is heavy and must install
the transmitter. In the environment where the vibration is heavy you will have to install the
transmitter by using an assistant support. In the case of severe vibration, promote to mount on
pipe using a mounting bracket as option.
4.8.2 Consideration of Transmitter Access
When selecting the establishment location or a place of the transmitter, it treats the transmitter
it probably is a location that is convenient must consider.
① Rotation of housing: housing can be rotated up to 90°.
② Terminal sides of transmitter: location ease us terminal space where be able to pull out
transmitter cover
③ Circuits side of transmitter: the space where there is a possibility of treating a electronic
circuit / the space where be able to pull out transmitter cover / If LCD meter is installed, it
requires extra space.
4-8-3. Housing Rotation and Lock Screw
Figure 4-8. Lock Screw
After Transmitter installation, housing can be rotated for wiring work or adjusting indication
direction of indicator. To rotate housing, loosen Rotation Lock Screw and rotate housing to the
desired direction. After completing housing direction adjustment, do not forget to tighten
Rotation Lock Screw to fix housing.
<Note> Housing is mechanically designed to be rotated up to 360°. In case of forced
rotation exceeding the limit, Transmittermay be damaged.
Page 53
APT3500 Smart Pressure Transmitter Operation Manual M3500-EO1G
51 DUON System Co., Ltd.
After completely removing Rotation Lock Screw and Housing Lock Screw, it is possible to
separate housing and sensor body of Transmitter by rotating housing. But, internal electronic
boards should be removed in advance before separating housing and sensor body.
Cover Lock Screw fixes the front and rear covers to prevent them from loosening. Fully
loosened, the Screw is stuck to the Cover side and Cover is fixed not to turn. Closing Cover Lock
Screw again, you can open it by turning Cover.
4.9 Environmental Considerations
4.9.1 Effect of Ambient Temperature
You have to install at -20℃~60℃ (-4~180℉), operating ambient temperature range. If predicted
heat seems to exceed or equivalent to ambient temperature range limit, you have to consider
additional method to cutoff the process heat.
4.9.2 Environment of toxic, moisture
Housing of APT-3100 can be protected to moisture or toxic material. Electronic circuit side is
separating from terminal side. When O-ring Seal cover covers, it is intrinsic safety. But, some drip
could penetrate to the housing of transmitter through conduit pipeline. Therefore, transmitter
should be set up over the position of conduit pipe for preventing drip.
4.9.3 Installation of dangerous place
Transmitter is designed to explosion-proof housing. Installation environment of transmitter must
be confirmed explosion-proof specification.

5.8 Configuration of Breakdown Diagnostic Function
5.8.1 Loop Test
The Loop Test verifies the output of the transmitter, the integrity of the loop, and the operations
of any recorders or similar devices installed loop. Perform the following procedure for a loop test.
① Connect a reference meter to the transmitter.
② Select the Loop Test of HHT and operate the Loop Test.
③ Select output current ( 4mA/20mA/etc )
④ If the readings match, then the transmitter and the loop are configured and functioning
properly. If the readings do not match, then you may have the current meter attached to the
wrong loop, there maybe a fault in the wiring, the transmitter may require an output trim, or the
electrical current meter may be malfunctioning.
5.9 Calibration
Scaled system implement by calibrating the transmitter. Trim function have several function for the
Page 57
APT3500 Smart Pressure Transmitter Operation Manual M3500-EO1G
55 DUON System Co., Ltd.
calibration. Smart transmitters operate differently than analog transmitter. A Smart transmitter uses
a microprocessor that contains information about the sensor's specific characteristics in response to
pressure and temperature inputs for calculating Process Variable. The trim and rerange functions
also differ. Reranging sets the transmitter analog output to the selected upper and lower range
points and can be done with or without an applied pressure. Reranging does not change the factory
characterization curve stored in the microprocessor. Sensor trimming requires an accurate pressure
input and adds additional compensation that adjusts the position of the factory characterization
curve to optimize transmitter performance over a specific pressure range. Rerange functions
provides ability to readjust the 4~20mA points sensor inputs.
Figure 5-2. Calibration Environment
Detailed Calibration Procedure is as follows:
1) In the complete vent mode without pressure approval, check measured value of HHT or PC Configurator.
2) After approving the pressure to be checked (in general URV) from the pressure source, check measured
value of HHT or PC Configurator and compare it with approved pressure.
3) After examining measured values, if the error turns out to be offset component execute Zero Trim or Zero
Adjustment, and if slope is changed execute Full Trim. After Trim, check measured values again.
4) In the same method, check ampere meter in the vent mode and pressure approval mode.
5) In the event of error to measured values, check out the Transmitter set-up state, such as set-up range (URV,
LRV), Transfer function, and Lowcut.
6) In the event of error to ampere meter even after checking set-up value, execute DAC Trim. After Trim,
check measured values again.

Figure 5-3 shows the above Calibration Procedure.
Figure 5-3. Calibration Procedure
5.9.1 Sensor Trim
The Sensor Trim the transmitter sensor input signal convert A/D to lead and how it interprets the
values which it inputs with digital the contents of such interpretation and it is regarding to change
is connected actually in the sensor which in order to correspond.
There are three waysto trim the sensor: Sensor zero trim, full trim and zero adjustment.
Sensor zero trim is a one-point adjustment typically used to compensate for mounting position
effects or zero shifts caused by static pressure.
Two point trim is a full sensor tirm, in which two accurate end-point pressure are applied (equal
to or greater than the range values), and all output is linearized between them. You should
always adjust the low trim value first to establish the correct offset.
Page 59
APT3500 Smart Pressure Transmitter Operation Manual M3500-EO1G
57 DUON System Co., Ltd.
Zero Trim and Zero Adjustment are functions
to control offset in the Transmitter
measurement. If a constant error occurs over
the whole region from low pressure to high
pressure as in Figure 5-4, it is possible to
eliminate measurement error by controlling
offset.
In the complete vent mode with no pressure
approval to Transmitter, execution of Zero Trim
can eliminate offset which occurred at the
zero point.
To control the currently measured value to a
certain value without pressure vent, Zero
Adjustment can be executed. In this case,
offset is controlled to move the currently
measured value to desired value. At the time
of Zero Adjustment execution, the currently
approved pressure should be maintained
constantly, and sufficient time should be given for the pressure approved after pressure change
to be stabilized prior to execution. As for Zero offset, set-up value for user and factory initial value
are stored separately, and the factory initial value can always be restored through offset factory
recall function.
As for how to execute Zero Trim and Zero Adjutment making use of button, refer to Chapter 3-7.
As for how to execute Zero Trim and Zero Adjutment making use of HHT, refer to each
corresponding HHT manual or STT30 manual.
A full trim is a two-point sensor
calibration where two end-point
pressures are applied, and all output
is linearized between them. You
should always adjust the low trim
value first to establish the correct
offset. Adjustment of the high trim
value provides a slope correction to
the characterization curve based on
the low trim value. The factory-
established characterization curve is
not changed by this procedure.
The trim values allow you to optimize
performance over your specified
measuring range at the calibration
temperature.
Simply, Zero Trim & Zero
Adjustment give Offset to the
Page 60

58 DUON System Co., Ltd.
transmitter and configure them without changing the slope of characterization curve but Full trim
change the slop of characterization curve after configuration.
Step for Full trimming.
(1) Set up stable pressure at 0 % of what user wants to the device during stabilization time, and
then input the low trim value on 0 %.
(2) Set up stable pressure at 100% of what user wants to the device during stabilization time, and
then input the high trim value on 100%.
5.9.2 DA (Digital to Analog) Trim
When the D/A trim convert sensor input signal to 4~20mA output, this ouput value scale
minuteness. Cyclic you recommend to scale analog output for maintain scale.
This function can manage the error about analog conversion if digital value for loop current output.
