Introduction

This is the users’ manual for Moore Industries’ advanced current-to-pressure transmitter, the IPT2. It contains all of the information needed to confi gure, install, operate, and maintain the IPT2.
The following guidelines are used in this manual:
WARNING - Hazardous procedure or condition that could injure the operator.
Caution - Hazardous procedure or condition that could damage or destroy the unit.
Note - Information that is helpful for a procedure, condition, or operation of the unit.
The IPT
The IPT2 is a compact, closed-loop, 2-wire current-to­pressure transmitter that converts a standard process current signal to a pneumatic output. In its compact aluminum housing, the IPT mounting rails or onto a Moore Industries RIR or SIR. Because of the low dynamic mass of the transducer element, the unit can be mounted in any position and is also insensitive to shock and vibration.

s consist of two parts: the transmitter
block, which snaps onto a rail. Units that are ordered without a mounting block will clip onto an RIR or SIR, which supplies air to each unit using only one pneumatic supply pipe. Both mounting blocks and supply headers contain self-sealing valves. Therefore, the IPT
2
can be removed and replaced without disturbing the pneumatic connections or causing accidental venting of the supply or output air.
Operation can be monitored or calibration performed by using the electrical input and optional pneumatic output test jacks. A red LED display, which indicates the presence of an electrical input signal, is also standard.
Table 1 contains the IPT

equipment specifi cations, including inputs, outputs, power requirements, and performance characteristics.
Model Number. The IPT
2
model number describes the equipment type, functional characteristics, operating parameters, any options ordered, and unit housing. If all other documentation is missing, this number is used to identify equipment characteristics. The model number for the IPT
2
is located on a label
on the side of the unit.
Serial Number. Moore Industries maintains a complete history on every unit it sells and services. This information is keyed to the serial number. When service information is required on the IPT
2
, it is necessary to provide the factory with this number. The serial number is located on the side of the unit.

transmitters utilizes an internal feedback loop to ensure accurate operation. The feedback loop consists of an internal pressure transducer that samples the unit’s output pressure and compares it to the input signal. This allows the unit’s output to track the input signal. Other I/P transmitters, such as our original IPT, IPH and IPX models, rely solely on mechanical positioning. This is what makes the IPT

highly desirable. Since the feedback loop requires power to operate, when there is no input power to the unit, the pneumatic output will be shut off . Units that use mechanical positioning only, will typically still have a pneumatic output (18 PSIG typically) when power is removed. This is not an issue except for those users that rely on this elevated output (18PSIG) to maintain a valve’s position upon the unexpected loss of input signal (4-20mA). In such cases, the IPT2, reacts diff erently by shutting off the pneumatic output.

Instrument Air and Filtration Information

Note:
For optimum performance, the selection and
use of a good quality air fi ltration system is
essential. Most users fi nd that it is much less
expensive and troublesome to design a system
that includes good air fi ltration than deal with
downtime and repairs later.
A clean, dry air supply is important to assure the maximum service life of an IPT volves removing solids, oil and water from the air after compression. The cleaner the air, the longer the time before servicing is needed.
Oversizing elements avoids performance abberations and reduces maintenance time. Redundancy should be used where possible to avoid shutdown during maintenance.
Solids: Random solid dirt, such as pipe scale and rust, is rarely a problem in compressed air instrument sys­tems. A good fi lter removes these solids. However, if there is a desiccant dryer in the line, a high-effi ciency sub-micron fi lter is recommended to remove the highly abrasive sub-micron particles produced by the dryer.
Liquid Oil: Liquid oil is the most common problem in compressed air instrument systems. A coalescing fi lter removes sub-micron liquid droplets from the air, and is usually supplied with an automatic drain.
A coalescing fi lter works by trapping oil and water droplets in a bed of microfi bers. The droplets run together at fi ber cross-over points, form large liquid drops, and are forced by air fl ow to a drain. A fi lter system consisting of a general purpose fi rst-stage fi lter (about 5 micron) and a high-effi ciency coalescing fi nal fi lter is recommended to obtain contaminant-free air.
2
. Good air quality in-
Suffi cient water must be removed to lower the dew point of the air to a temperature below ambient. The dew point (at line pressure) is expressed as the tem­perature at which any moisture in the system begins to condense.
Water may be removed using a number of techniques, including coalescing fi lters, refrigeration dryers and desiccant dryers. In addition, a variety of combina­tions and modular systems may be used for special circumstances.
Care must be taken in the selection and location of the fi lter, because cooling downstream of the fi lter can cause more condensation of water. A coalescing fi lter should be installed immediately upstream of the pres­sure regulator. This type of fi lter removes most of the water before the air enters the regulator.
For systems subjected to freezing temperatures, the portion of the system that runs outdoors should have a dryer installed. The dryer reduces the dew point below the lowest expected outdoor temperature. A desic­cant dryer is used with a coalescing fi lter upstream to keep the desiccant dryer from being damaged by oil or overloaded with excessive condensed water. Another high-effi ciency coalescing fi lter is recommended down­stream of the dryer, to remove the desiccant particles.
ISA Specifi cations: The Instrument Society of America standard ISA-S73, 1975 (ANSI MC11.1-1975) covers the air quality requirements for instrument grade air for use in pneumatic installations.
The dew point in outdoor installations must be at least
7.8°C (18°F) below the minimum local ambient tem­perature. For indoor installations, the dew point must be at least 7.8°C (18°F) below the minimum interior temperature or 2°C (35°F), whichever is greater. Although the ISA standard calls for a 35°F dew point, this is often unnecessary indoors, and may be unsatis­factory outdoors under freezing conditions.
The exact location of the fi rst-stage fi lter is not im­portant; it can be located just ahead of each fi nal fi lter, or a single fi rst-stage fi lter can be located on a main line to protect a number of fi nal fi lters on branch lines. Each fi nal fi lter (coalescing) should be located just ahead of each pressure regulator. In a new plant installation, an oilless compressor may be used to eliminate this problem.
Water: The amount of water in an air system depends on temperature, pressure and the relative humidity of the air.
Filters that exceed the ISA specifi cation provide very inexpensive protection. Although the ISA specifi cation calls for particle size not to exceed 3 microns and oil content not to exceed 1ppm, most fi lter manufacturers supply a line of coalescing fi lters that remove particles down to sub-micron sizes (often 0.01 micron) while also removing oil to below ISA 1ppm specifi cation (often to 0.01ppm).

Application Information

Any approach to providing good instrument air quality should evaluate the worst case air fl ow and ambient temperature of the location. This is required to determine sizing of the air system elements. A knowledge of yearly humidity cycles is also important for this evaluation.
Caution:
Before placing IPT
and mounting blocks or headers (SIRs or RIRs)
should be "blown down" to purge contamination and
condensation deposited during piping and installation.
Also blow down lines to loads, since all output air
vents back through the IPT
lters installed to trap these contaminants (normally
only present at start-up). It is recommend this be
done for at least an hour, longer if there is evidence of
water or oil coming through.
The IPT
2
requires periodic maintenance. Service in the fi eld is limited to visual inspection and cleaning of the input nozzle fi lter screen on the IPT2 and servicing of the compressed instrument air fi ltration system. The unit may be returned to the factory for complete disassembly, cleaning, and servicing on a periodic basis.

, and there are never
The use of coalescing fi lters with retention of 0.01 micron particles and droplets is recommended; they remove all undesirable traces of oil and water droplets. Proper placement with respect to the regulator may eliminate the need for dryers, except when coalescing fi lters are exposed to freezing temperature (keeping in mind that the dew point of the purifi ed air must be kept below worst case ambient).
Figures 1 and 2 illustrate typical non-redundant systems with multiple branch lines. They both work in any environment above freezing and diff er only in the placement of the general purpose fi rst-stage fi lter. Gauges, valves, and diff erential pressure indicators (for fi lter service monitoring) are not shown. It is recommended that fi lters with integral service life indicators or diff erential pressure indicators be used to help ensure proper servicing, as well as redundancy to avoid shutdown during servicing.
Figures 1 and 2 diff er in the method used to remove water. The use of a desiccant type dryer (Figure 2) requires upstream fi ltration to prevent oil contamination of the desiccant, as well as downstream fi ltration, to prevent desiccant fi nes from introducing new contamination.
The service life of an IPT
2
is directly proportional to the cleanliness and dryness of its air supply. The small cost of providing high-quality air ensures a longer, more trouble-free service life for the unit.

Calibration

This section provides information necessary to adjust and calibrate the IPT2. Each unit is calibrated and checked at the factory prior to shipment. Before installation, every IPT for proper operation. Generally, these checks, which are specifi ed under Calibration Procedures, require little or no adjustment.
Adjustments
The IPT2 has Zero and Span adjustments located on its front panel. The type of potentiometer used with these adjustments usually require 15 turns of the shaft to move the wiper from one end of its range to the other. It is equipped with a slip clutch at each end to prevent damage if the adjustment is turned beyond the wiper stop. Usually a slight change can be felt when the clutch is at the end of a range (i.e., it is slipping). However, if this change is not felt, either

end can be reached by turning the shaft 15 turns in the desired direction.
Turning these potentiometers clockwise causes the related output to increase in quantity or become more positive; while turning them counterclockwise causes the related output to decrease in quantity or become more negative.
The Zero and Span potentiometers provide an adjustment range of ±10% of full scale.

Test Jacks

The +T and –T test jacks on the front of the IPT2 are provided as a convenient means of monitoring the process loop to which the product is connected without disconnecting the unit or interrupting the loop.
A milliammeter connected to the +T and –T test jacks will provide a reading in the range of the unit's output rating (Figure 3). The model number of the IPT
2
shows its output range.
Caution:
The maximum resistance the milliammeter can
introduce into the test jack circuit and still provide
accurate readings is 10Ω.
If the milliammeter readings are not as anticipated, verify that the milliammeter is rated for no more than 10Ω impedance. If the unit is suspect of improper operation, remove it from the test jacks and calibrate
the IPT
2
.

Calibration Setup

Figure 3 is an illustration of a typical calibration setup, including optional equipment. To check or calibrate the IPT
2
, connect the unit as shown in this illustration.
Calibration Procedure
There are two options shown in Figure 3 for monitoring the output of the IPT2. The input current may be measured by placing a milliammeter in series with the input terminals as indicated by M1 or connected across the electrical test jacks by a milliameter of less than 10Ω impedance (+T and -T) as indicated by M2.
1. For zero adjustment, connect an adjustable
current source to the electrical input terminal block. Set the current input signal for zero percent output (e.g. 4mA for a 4-20mA input, 3-15psig output; 20mA for a 4-20mA input, 15­3psig reverse output).
Note:
Observe that the red LED indicator on
the front panel is illuminated at zero input
current and glows somewhat brighter with
increasing current.
2. Using an air pressure gauge to measure the input
air supply pressure, connect a fi ltered air supply to the pneumatic supply port located on the bottom or rear of the unit.
3. If the unit is supplied with the optional front-
access pneumatic-output test jack, insert the pneumatic coupler into the receptacle. This avoids having to disturb any operating connections or fi ttings.

Caution:
Coupler must be kept lubricated to prevent
damage to O-rings in test jacks. Tefl on
lubricant is recommended. If grease is used,
keep out of air passage.
If the unit is not supplied with the output test jacks, use an air pressure gauge to measure the output air supply pressure (e.g., read 3psig for a 3-15psig unit or 15psig for a 15-3psig unit).
4. Any deviation in the output pressure (e.g., 3 psig for a 3-15 psig unit or 15 psig for a 15-3 psig unit), can be corrected by using the Zero potentiomenter in a range of ±10%.
5. Set the current input signal for 100 percent output (e.g. 20mA for a 4-20mA input, 3-15psig output; 4mA for a 4-20mA input, 15-3psig reverse output).
6. Any deviation in the output pressure (e.g., 15 psig for a 3-15 psig unit or 3 psig for a 15-3 psig unit), can be corrected by the Span potentiometer over the range of ±10%.
7. Repeat steps 1 through 6 (as applicable) until no further adjustments are required.

Installation

Installation of the IPT2 is divided into three phases: mounting, electrical connections, and pneumatic con­nections. In most cases, it is easier to mount the IPT2 before completing the electrical and pneumatic con­nections.
Mounting
Individual IPT2s consist of two parts: the transmitter and the mounting block. Units without a mounting block snap onto a header. IPT are rail mounted. Ensure that the unit is mounted in an area free of dust, moisture, and corrosive elements. See Figure 4 for mounting dimensions.
It is recommended that mounting blocks and headers be purged of any debris prior to mounting the IPT sert a small diameter, blunt tip probe into the fi tting and unseat the ball-check valves for a few minutes with the
ltered instrument air supply in operation.
Rack- or surface-mounted IPT with a Moore Industries' rack-mounted header (RIR) or a surface-mounted header (SIR). This eliminates the need for an interlocking mounting block and rail. 5, 10 or 15 units can be snapped onto one header, allowing multiple units to receive supply air from one supply pipe. To mount an IPT into place until the retaining lever snaps up fl ush be­neath the handle. To remove an IPT2, press down on the retaining lever and lift the unit out by the handle.

Electrical Connections
The electrical connections are made to the removable terminal blocks located on the front of the unit. There are two terminals on the IPT current.
The electrical terminals are compression screw sockets that accept 22 to 14 AWG hookup wire. To complete these connections, use a slotted screwdriver with a head approximately 0.125 inch (3mm) in width to secure the wire leads to the transmitter. Loosen each screw prior to inserting the wire being terminated. Strip and then tin the end of each wire with 60/40 solder. Then, while holding the uninsulated end of the wire in place, tighten the screw of the corresponding terminal.

10 The Interface Solution Experts
• Any Moore Industries product in a metal case or housing should be grounded.
• The protective earth conductor must be connected to a system safety earth ground before making other connections.
• All input signals to, and output signals from, Moore Industries’ products should be wired using a shielded, twisted pair wiring technique. Shields should be connected to an earth or safety ground.
• For the best shielding, the shield should be run all the way from the signal source to the receiving device. (see Note below)
• The maximum length of unshielded input and output signal wiring should be 2 inches.
Note:
Some of Moore Industries’ instruments can be
classifi ed as receivers (IPT
2
, IPX2, etc.) and some can
be classifi ed as transmitters (TRX, TRY, etc.) while
some are both a receiver and a transmitter (SPA
2
,
HIM, etc). Hence, your shield ground connections
should be appropriate for the type of signal line being
shielded. The shield should be grounded at the
receiver and not at the signal source.
CE Conformity
Installation of any Moore Industries’ products that carry the CE marking must adhere to the guidelines in the Recommended Ground Wiring Practices section in order to meet the EN 61326 requirements set forth in the applicable EMC directive.

Operation

Reverse output operation:
Once adjusted and installed, the IPT2 operates unattended, except for occasional cleaning of the air supply fi lters.
If a malfunction is isolated to the IPT2, refer to the Troubleshooting section for recommendations. A unit may become warm during operation, especially where the ambient temperature is elevated. This is normal and should not be cause for alarm.
The high-performance line of I/P transmitters utilizes an internal feedback loop to ensure accurate operation. The feedback loop consists of an internal pressure transducer that samples the unit’s output pressure and compares it to the input signal. This allows the unit’s output to track the input signal.
Since the feedback loop requires power to operate, when there is no input power to the unit, the pneumatic output will be shut off . Units that use mechanical positioning only, will typically still have a pneumatic output when power is removed.
This is not an issue except for those users that rely on this elevated output (18PSIG) to maintain a valve’s position upon the unexpected loss of input signal (4-20mA). In such cases, the IPT shutting off the pneumatic output.

Maintenance

After the IPT2 has been installed into the application, no maintenance is required.
However, the IPT2 is equipped with a plunger to clean the orifi ce. To use the orifi ce-plunger, depress the plunger located on the side of the unit. This pushes a stainless steel wire through the orifi ce and removes any particles lodged inside. The output pressure will fl uctuate when the plunger is activated.
If the plunger does not fi x the problem, the supply air fi lter screen should be removed and fl ushed with trichloroethance (TCE) and then air dried before replacement. Follow the directions below.
1. Remove the IPT2 from the mounting block by pressing down on the locking lever and pulling straight out to disengage the pneumatic fi ttings.
2. To remove the supply air fi lter screen, fi rst slide the nozzle retainer clip to the right and then pull the nozzle out of the main body.
3. Remove the fi lter screen and fl ush with TCE and air dry before reinstalling.
4. Slide the nozzle back into the main body.

Troubleshooting

Many components of the IPT2 have been thermally aged, tested, and selected using a computer-aided design program. This usually makes fi eld repair unnecessary. It is therefore recommended that any unit found to be performing below specifi cations be returned to the factory in accordance with the instructions found on the back cover of this manual.
If a problem is suspected with the IPT following steps:
1. Make sure that all connections are clean and tight.
2. Verify that bench instruments used to take measurements have the proper range and accuracy and are currently certifi ed.
3. Check that the bleed-air port (located in a slot on the right side panel) is not restricted.
4. Using a test jumper, connect one end to the metal case and the other end to an "IN" terminal while observing the output pressure. The output pressure should not change.
5. If a change in the relationship between the input and the output occurs, try to correct it by re­adjusting the Zero and Span controls.
6. If the response time lengthens or the span drops, this may indicate a blockage due to air supply contamination. Clean the orifi ce and the supply air fi lter as described in the Maintenance section.

RETURN PROCEDURES
To return equipment to Moore Industries for repair, follow these four steps:
1. Call Moore Industries and request a Returned Material Authorization (RMA) number.
Warranty Repair –
If you are unsure if your unit is still under warranty, we can use the unit’s serial num­ber to verify the warranty status for you over the phone. Be sure to include the RMA number on all documentation.
Non-Warranty Repair –
If your unit is out of warranty, be prepared to give us a Purchase Order number when you call. In most cases, we will be able to quote you the repair costs at that time. The repair price you are quoted will be a “Not To Exceed” price, which means that the actual repair costs may be less than the quote. Be sure to include the RMA number on all documentation.
2. Provide us with the following documentation: a) A note listing the symptoms that indicate the unit needs repair b) Complete shipping information for return of the equipment after repair c) The name and phone number of the person to contact if questions arise at the factory
3. Use suffi cient packing material and carefully pack the equipment in a sturdy shipping con­tainer.
4. Ship the equipment to the Moore Industries location nearest you.
The returned equipment will be inspected and tested at the factory. A Moore Industries rep­resentative will contact the person designated on your documentation if more information is needed.
The repaired equipment, or its replacement, will be returned to you in accordance with the shipping instructions furnished in your documentation.
