IntroductionThis users’ manual for Moore Industries’ IPH2 andIPX2 Current-to-Pressure Transmitters contains all ofthe information that is needed to calibrate, install,operate, maintain, and troubleshoot this family oftransmitters.

The following guidelines are used in this manual:

WARNING - Hazardous procedure or condition thatcould injure the operator.

Caution - Hazardous procedure or condition that coulddamage or destroy the unit.

Note - Information that is helpful for a procedure,condition, or operation of the unit.

IPH2 & IPX2The rugged IPH2 and IPX2 Current-to-Pressure (I/P)Transmitters are designed specifically for extendedduty in harsh field environments. Meeting NEMA 4Xand IP56 requirements, the IPH2 is watertight, dust-protected, and highly resistant to corrosion and chemi-cals. The extruded aluminum housing of the IPX2

(IP66, NEMA 4X) is explosion-proof and waterproof,making it perfect for most any location.

These 2-wire (loop-powered) transmitters convert acurrent signal to a pneumatic signal so that an elec-tronic-based system such as a DCS, PLC, or PC cancontrol a pneumatic actuator, valve, or damper drive.Available models accept a wide range of current inputs(4-20mA, 4-12mA, and 12-20mA) and provide a propor-tional pneumatic signal (3-15psig, 0.2-1Bar,20-100kPA, etc.). Reverse pneumatic outputs are alsoavailable.

Both units are available with an optional coalescingfilter/regulator that combines an air filter and miniaturesupply line regulator with a pressure gauge that reads inboth psi and Bars.

CalibrationEvery IPH2 and IPX2 is fully tested and calibrated at thefactory prior to shipment. However, before installation,your IPH2 or IPX2 should be bench-checked to verify thedesired unit zero and unit span. Calibration should beconducted in an appropriate testing environment.

Necessary EquipmentTable 1 lists the equipment required to calibrate theunit. This equipment is not supplied by Moore Indus-tries, but should be available in most labs or mainte-nance areas.

NOTE: WHILE THE IPH2 AND IPX2 WILLVARY IN APPEARANCE FROM THE UNITSHOWN HERE, SIMILAR LABELS AREUSED. SIMPLY CONNECT THE WIRESTO THE TERMINALS THAT HAVE THESAME DESIGNATIONS

Preparing for CalibrationTo prepare the IPH2 or IPX2 for calibration, remove thescrew-on cap and connect the unit to your configura-tion equipment as shown in Figure 1.

Unit Connections and Controls. The IPH2 and IPX2

each have two labeled terminals on their faceplate,located under the top protective cover of the housing.The terminal labeled “+PS” is for connection of thepositive current input, and the terminal labeled “–PS”is for the negative connection.

The two controls are also located inside the unithousing under the screw-on cap. They consist of twopotentiometers, each accessed through the front panel.They are labeled “zero” and “span”. The zero potentiom-eter provides a control range for offsets of ±10% ofrated unit span, while the span potentiometer adjustsunit full-scale output to 100 percent of rated span.

Each potentiometer requires approximately 20 turns tomove its wiper from one extreme to the other: clockwisefor maximum, or counterclockwise for minimum values.Each is equipped with a slip clutch to prevent damage ifthe adjustment is turned beyond the wiper stop.

IPH 2 & IPX 2


Note:Always use clean, dry, instrument air whencalibrating or operating the IPH 2 or IPX 2.

All pneumatic lines used in calibration and operationmust be “blown down” (purged) prior to connection tothe unit. Any condensation or oil residue in the lines, ifintroduced into the pneumatic chambers of the unit,may result in poor unit performance.

Calibration ProcessTo perform the recommended bench-check for the IPH2

or IPX2, first perform the setup as described in the nextsection. See Figure 1 for illustration of the CalibrationSetup, then follow the steps under Calibration Setupand Calibrating the IPH2 or IPX2.

Calibration Setup

1. Connect 1/4-inch pneumatic tubing between theappropriate output port of the regulated instrumentair supply and the pressure gauge #1 (accuracy of±2% of span). Connect another tube from thepressure gauge to the port labeled “IN” on IPH2 orIPX2.

2. Connect 1/4-inch pneumatic tubing between theport labeled “OUT” and the appropriate port ofpressure gauge #2 (accuracy of ±0.1% of span),then from gauge #2 to the appropriate pneumaticload.

3. Run current source wiring through conduit openingin housing, and to the front panel of the IPH2 orIPX2. (Not necessary for IPX2 –NG models.)

4. Connect positive lead of adjustable current sourceto the +PS terminal of unit. Connect negativesource lead to the –PS terminal. (For IPX2 –NG,connect the positive lead of the current source tothe red wire, and the negative lead of currentsource to the black wire.) A multimeter may alsobe connected to verify level of current input.

5. When connections are complete, apply an inputcurrent of 0% of span. (i.e. 4mA for a 4-20mA unit)

6. Apply appropriate filtered, instrument-quality air tosupply line: 20 or 35psi (1.4Bar to 2.4Bar). Verifyappropriate supply pressure by checking SupplyPressure field of unit model number.

7. Allow approximately 30 seconds for calibrationsetup to stabilize.

Calibrating the IPH2 or IPX2

This calibration procedure consists of a basic checkand adjustment of unit zero and span, based on thereading of pressure gauge #2. To calibrate, perform thefollowing:

1. Check unit zero setting. Monitor reading of pres-sure gauge #2 (output), and turn zero potentiometercounterclockwise to lower output, clockwise toraise output. Set zero potentiometer so thatpressure output is at 0% of span when a currentinput of 0% of span is applied. (i.e. 3psi for a3-15psi unit)

2. Check unit span setting. Increase input to 100% ofrated span (i.e. 20mA for a 4-20mA unit).

3. Monitor reading of pressure gauge #2 (output), andadjust span potentiometer so that reading is at100% of span for your unit (i.e. 15psi for a 3-15psiunit).

4. Repeat steps 1 through 3 until the unit outputs 0%of rated pressure range at 0% current input, and100% of output pressure range at 100% of span.

5. Verify the accuracy of your adjustments byinputting 0%, 25%, 50%, and 75% of span inputs,and monitoring the output.

IPH 2 & IPX 2


InstallationThe installation of the IPH2 or IPX2 is carried out inthree phases: the physical mounting of the unit, theelectrical connections phase, and the pneumaticconnections phase. It is strongly suggested that eachunit be calibrated according to the instructions in thismanual before being placed into service.

Phase One: MountingFigures 2 and 3 give the dimensions of the IPX2 andIPH2, respectively. The illustrations also give thedimensions of the available option hardware, which isrecommended for most installations. After placing theunit in the desired location and orientation, secure thehousing with the optional pipe mounting hardware orother appropriate fasteners.

The IPH2 or IPX2 may be installed at any angle–eithersurface-mounted or attached to pipe or round conduit.However, if water entering the I/P unit is a consider-ation, the IPH2 should be mounted within 45° of vertical,while the IPX2 should be mounted with at least one venton a low side. The IPX2 with natural gas (–NG1 or–NG2) option does not have an open vent, so water isnot a consideration.

Phase Two: Electrical ConnectionsTo complete the electrical connections, route thewiring through the conduit port to the terminal block,then use a slotted-tip screwdriver with a maximumhead width of 3mm (0.125-inch) to loosen theterminal screws. (Not necessary for IPX2 –NG1 or–NG2 installation.)

For all units except the IPX2 –NG1 or –NG2, connectpositive lead (+) to the +PS terminal, and negative lead(–) to the –PS terminal. Tighten the terminal screwsuntil snug.

Caution:When connecting the IPX 2 Natural Gas (–NG1 or –NG2)

model, use an appropriately certified conduit box andwire connectors. Do not attempt to remove the sealfitting, as it is necessary for natural gas certification.Connect the positive lead (+) to the red wire from theseal fitting, and the negative lead (–) to the black wire

from the seal fitting.

Use shielded, twisted-pair wiring for low-level input.Ground the shielding wire as close as possible to theinstalled unit.

Recommended Ground Wiring PracticesMoore Industries recommends the following groundwiring practices:

• Any Moore Industries product in a metalcase or housing should be grounded.

• The protective earth conductor must beconnected to a system safety earth groundbefore making any other connections.

• All input signals to, and output signalsfrom, Moore Industries’ products should bewired using a shielded, twisted pairtechnique. Shields are to be connected to anearth or safety ground at the unit itself.

• The maximum length of unshielded inputand output signal wiring should be 2-inches.

Power Sourcing Parameters for GeneralLocations, Intrinsically Safe, andNon-Incendive/Type N applicationsIn accordance with IEC 1010.1 Annexes F.2.1 and H(all models) or any equivalent international standard,the input terminals must be connected to and/orsupplied from a certified energy limiting Class 2 or aSeparated Extra Low Voltage (S.E.L.V.) power supplyseparated from all mains by double/reinforcedinsulation.

CE ConformityInstallation of any Moore Industries’ products thatcarry the CE certification (CommissionElectrotechnique) must adhere to the guidelines inthis manual in order to meet the requirements setforth in applicable EMC (ElectromagneticCompatibility) directives (EN55011, EN 50082-1,EN50082-2, etc.) Consult the factory for the mostcurrent information on products that have been CEcertified.

IPH 2 & IPX 2


Phase Three:Pneumatic ConnectionsTo complete the final phase of installation, connect thesupply line to the ¼-inch NPT female port labeled “IN”.Connect the output line to the ¼-inch NPT female portlabeled “OUT”. All tubing must have at least 6mm(¼-inch) inside diameter or the maximum flow will belimited.

Note:Seal all fittings with Teflon® tape, or equivalent.Always “blow down” (purge) all tubing and the

controlled device before connecting the IPH2 or IPX2.

Manual Override ScrewIf you are in a potentially explosive environment and donot want to apply electric power to the unit with thecover removed, the pneumatic installation may betested by loosening the manual override screw on thebottom of the unit. The output pressure will go to thesupply pressure. Be sure to tighten the manual overridescrew after test.

WARNING:IPX 2 units installed in a natural gas application musthave the natural gas vent properly connected. Followthe directions below to install an IPX 2 with –NG1 or

–NG2 options into a natural gas application.

Natural Gas ApplicationsCustomers using the IPX2 with –NG1 or –NG2 optionsto regulate a sweet natural gas application (H

2S levels

are not to exceed 20ppm) must also make the vent portconnections. Connect the Natural Gas Vent (shown inFigure 2) to a device prepared to receive natural gas.After connection, the fittings, cover, and filter/testscrew should be tested for leaks.

For an outdoor system, ventilation should consist of aweather-proofed connection between the transmitterexhaust and a riser, six feet above the transmitter andcontrol valve assembly. The riser should be shepherd-crooked to prevent rain or incident water from accumu-lating at the base. In accordance with local safetyregulation, an in-line flame arrestor should be applied tothe riser to prevent flash back to the transmitter from anexternal, spontaneous flame source.

For an indoor system, ventilation must consist of aleak-proof connection from the exhaust of the transmit-ter to a process vent. The process vent should alreadybe dedicated for natural gas excursions and shouldconform to all standards for flaring or after-burn, andflame arrest, as dictated by local environmental andsafety regulations.

Indoor natural gas operations are typically monitored tomaintain safety conformance outside the lower andupper explosion limits (LEL and UEL). To add a naturalgas operated transmitter in these cases, considerationshould be made as to the extent of natural gas leakdetection legacy to the installed transmitter. Placementof the transmitter should be such that detection andalarming surround any critical connections between thetransmitter and the natural gas process.

If the natural gas driven transmitter is to be installedindoors with no legacy monitoring capabilities,additional consideration must be made to ensure theoperating area is well-ventilated and the transmitter canbe exhausted to process vent. Furthermore, monitoringwith remote annunciation within LEL and UEL should beprojected as an upgrade to the facility, concurrently withthis installation. The transmitter installation mustadhere to local environmental and safety regulations.

WARNING:IPX 2 units installed in a natural gas application must

have the natural gas vent properly connected. Failureto do so may result in an explosion. The –FR1 optionshould not be used with a flammable gas because ithas a vent to atmosphere. A filter-regulator without avent may be used. For natural gas certification to be

valid, the vent system must be able to maintain

IPH 2 & IPX 2


OperationOnce the unit has been configured and installed, itoperates unattended with the exception of the minormaintenance procedures that are described in the nextsection.

If the unit is determined to be the cause of a loopirregularity, carry out the maintenance procedure in thenext section of this manual. If problems persist, referto the Troubleshooting Section.

Instrument-quality Air. Air from the applicationcontinuously flows through the IPH2/IPX2 during opera-tion. Depending upon the purity of the air supply, theunit’s internal assembly may have to be removed andcleaned to ensure continued optimum performance.

Initially, random checks can help establish a satisfac-tory internal maintenance geared to the user’s airsupply cleanliness. Refer to the next section forinstruction on the disassembly and cleaning of yourunit.

MaintenanceFor most applications, no maintenance outside ofroutine inspection and calibration of the IPH2 or IPX2 willbe necessary. These units are designed to workunattended for up to six months with little change inaccuracy.

Occasionally, a unit will become clogged when its airsource becomes contaminated. An internal filter willprevent the control orifice and nozzle from beingclogged. To replace the filter, you will need to order thefilter and two (for IPX2) or three (for IPH2 and IPX2 –NG1or –NG2) o-rings from Moore Industries, (see Figure 4for part numbers) then follow the instructions below.This filter is not intended to replace any of the filtersdescribed in the Installation section.

Use a screwdriver to remove the filter holder from thebottom of the unit. Remove the orifice assembly andfilter from the filter holder, taking care not to lose any ofthe parts. Replace the filter and o-rings in the filterholder. Screw the filter holder back into place. If this isan IPX2 unit with –NG1 or –NG2 options and is beingused in a natural gas application, you will also want totest for natural gas leaks at this time.

Note:After maintenance, each IPH 2 or IPX 2 should be

recalibrated before it is returned to service. Referto the Calibration Section of this manual

for instructions.

Drain Check. System filters (not IPX2/IPH2 filters)have automatic drains that depend on the fluctuation ofsystem pressure to induce drainage. A stable systemmay not drain efficiently. Check periodically for clogsand drain system’s filters by pushing the drainage valvewith a small probe or wire.

Figure 4. Filter Replacement Diagram

IPH 2 & IPX 2


Troubleshootingthe IPH2 & IPX2Many components of the IPH2 and IPX2 have beenthermally aged, tested, and selected. This usuallymakes field repair unnecessary.

It is recommended that any properly maintained unitfound to be performing below specifications be returnedto the factory in accordance with the instructions foundon the back cover of this manual.

If a problem is suspected with the IPH2 or IPX2, reviewthe following steps:

1. Verify that bench instruments used to takemeasurements have the proper range and accuracyand are within current certification period limits.

2. If a change in the relationship between the inputand output is detected, attempt a re-calibration ofthe unit.

3. If the response time lengthens, or if the span drops,check the system for a blockage due to air supplycontamination.

The complete valve assembly can be removed from thehousing for replacement without disturbing the connec-tions to the housing. Contact customer service fordetails.

Customer ServiceIf service assistance is ever required for your IPH2 orIPX2, refer to the back cover of this manual for thetelephone numbers to Moore Industries’ STAR Centercustomer service department.

IPH 2 & IPX 2


Product/Technical Descriptive Notice

IPX2: Field-Mount I/P (Current-to-Pressure) Converter A loop-powered (2-wire) instrument that accepts a 4-20mA current signal input from a DCS, PLC or PC-based control system, and converts it to a proportional pneumatic output (3-15psig, 0.2-1Bar, 20-100Kpa, etc.) to provide precise, proportional control of valves, actuators, and other pneumatically-controlled devices. The IPX2 is designed and intended for use in industrial process control, factory automation, and facility environmental control applications. The IPX2 usage and operating environment covers both Non-Hazardous (General-Ordinary/Safe Areas) and Hazardous ‘Classified’ Locations. Special design, construction, and materials specifications allow the model IPX2 with the -NG1 or -NG2 option to be used with “natural gas” as its pneumatic supply (commonly referred to as “sweet gas”, consisting of up to 20ppm of Hydrogen Sulfide - H2S). This advantage allows the IPX

2 to be installed in remote compressor sites where it is too expensive or impossible to run a clean air supply. The standard IPX2 unit utilizes “air” as its pneumatic control medium. Detailed electrical guidelines, power ratings, mechanical features, terminal identification, wiring diagrams, model configurations, and technical instructions for commissioning, installing and operating the instrument are provided in the OEM User’s Manual, Product Literature (Data Sheet), Identification Label/Tag, and the Intrinsically Safe System & Field Installation Diagram that are shipped with each unit. Power must be sourced from a Class 2 power supply or Separated Extra Low Voltage (S.E.L.V.) Limited Circuits as defined by CSA standard 1010.1 - Annexes H & F.2.1 or any equivalent international standard. The IPX2 is in the process of acquiring numerous safety approvals in accordance with internationally adopted standards such as the CEC, IEC and NEC. For North America, the standard (air) IPX2 will qualify for CSA and FM certifications as an Explosion-Proof (Class I, II, III; Division 1; Groups A-G), Intrinsically Safe and Non-Incendive (Class I, Divisions 1 & 2, Groups A-D) apparatus. Within an ambient temperature range of -40oC to +85oC, the IPX2 will hold a T5@85oC/T6@60oC temperature classification code. For Europe, it will be certified by LCIE (France) as a Flame-Proof (II 2GD EEx d IIC T5/T6), Intrinsically Safe (II 1G EEx ia IIC T5/T6), and Type N (II 3G EEx nA II T5/T6) apparatus; to be clearly marked in accordance with the CENELEC/ATEX 94/9/EC Directive. The IPX2-NG will carry the same certifications as the standard IPX2 (air), excluding the Non-Incendive/Type N classifications. The IPX2 assembly consists of a pneumatic current-to-pressure transducer mounted in the IP56 (air) / IP66 (-NG) rated enclosures in accordance with the environmental protection requirements of Clauses 7.3.2 and 8.1 of EN 50014:1997 plus Amendments 1 & 2, and 6.1 of EN 50020:1994. As per CSA’s Standard 1010.1 (or any equivalent international standard), the environmental conditions are set as: Pollution Degree = 2, Installation Category = I, Altitude = 0 - 4000m (0 - 13,123ft), Humidity = 0 - 100% (non-condensing).

Manufacturer’s Declaration:

It is hereby declared that the above information pertaining to the IPX2 – produced by Moore Industries-Int’l., is concisely stated as a description of its design purpose and usage intent.

User’s Manual SupplementIPT2 and IPH2 & IPX2

Current-to-Pressure TransmittersReverse Output Range

April 2004

The following information accompanies data in theIPT2 Current-to-Pressure Transmitter User’s Manual,170-730-00, Revision A and the IPH2 & IPX2 Current-to-Pressure Transmitters User’s Manual, 170-755-00,Revision A .

This document concerns those of our customers that useour latest high-performance Current-to-Pressure Trans-mitters and have specified a reverse output range.

This supplement is for units with a base model designa-tion of IPT2, IPH2 and IPX2. Typical reverse outputranges are as follows:

170-730-02A© 2005 Moore Industries-International, Inc.

20 - 0PSIG17 - 1PSIG 15 - 3PSIG

16.6 - 3PSIG18 - 3PSIG27 - 3PSIG 30 - 6PSIG1 - .2KBAR 100 - 20KPA1 - .2KGCM2.10 - .02MPA

A typical complete model number would appear as:

IPT2/4-20MA/15-3PSIG/20PSI/-FA1 [DIN]

The high-performance line of I/P transmitters utilizes aninternal feedback loop to ensure accurate operation. Thefeedback loop consists of an internal pressure transducerthat samples the unit’s output pressure and compares itto the input signal. This allows the unit’s output to trackthe input signal. Other I/P transmitters, such as ouroriginal IPT, IPH and IPX models, rely solely on me-chanical positioning. This is what makes the IPT2, IPH2

and IPX2 highly desirable.

Since the feedback loop requires power to operate, whenthere is no input power to the unit, the pneumatic outputwill be shut off. Units that use mechanical positioningonly, will typically still have a pneumatic output whenpower is removed. By example, a unit (IPT, IPH andIPX) with an output range of 15 - 3PSIG will outputapproximately 18PSIG when the input signal is removed.This is not an issue except for those users that rely onthis elevated output (18PSIG) to maintain a valve’sposition upon the unexpected loss of input signal (4-20mA). In such cases, the IPT2, IPH2 and IPX2 unitsreact differently by shutting off the pneumatic output.

User’s Manual SupplementIPX2 Current-to-Pressure Transmitter

With -RO Option

February 2007

The following information accompanies the IPH2 & IPX2

Current-to-Pressure Transmitters User’s Manual (PartNumber: 170-755-00, Revision A) to include the modelIPX2-RO (IPX2 with -RO option). The IPX2-RO is aUser-Selectable Direct/Reverse Output version of MooreIndustries’ IPX2.

The IPX2-RO, which ranges from 3-27PSIG (Directmode)/27-3PSIG (Reverse mode), includes two sets ofZero and Span potentiometers (Direct and Reverse) alongwith a Direct/Reverse Selector Switch.

If the switch is placed in the Direct position, the instru-ment will behave as the standard IPX2 in that the Zeropotentiometer will adjust the 3PSIG end while Spanadjusts the 27PSIG limit. The direct output will rangefrom 3-27PSIG.

Setting the switch to the Reverse position places theinstrument in reverse output mode. The Zero potentiom-eter will adjust the 3PSIG end while Span adjusts the27PSIG limit. The reverse output will range from27-3PSIG.

With the exception of the information outlined above, theIPX2-RO behaves and operates just as the IPX2 andadheres to the specifications and instructions describedin the IPH2 & IPX2 Current-to-Pressure TransmittersUser’s Manual.
