The 2-wire (loop-powered) IPH accepts a 4-20mA input from a DCS, PLC or PC-based control system. It converts the current signal to a pneumatic signal (3-15psig, 0.2-1 Bar, 20-100 kPa, etc.), providing precise proportional control of valves, actuators, and other pneumatically-controlled devices. Reverse pneumatic outputs (15-3psig, 1-0.2 Bar, 100-20 kPa, etc.) are also available.

The IPH is available with an optional coalescing filter/regulator that combines an air filter, a miniature supply line regulator, and a pressure gauge that reads in both psi (0-60) and Bars (0-4).

Model/Serial Number. Moore Industries tracks all their IPH units with a system of model numbers and serial numbers. Please be prepared to provide these numbers if you need service information or assistance.

The IPH serial and model numbers can be found on the instrument’s metal tag.

Calibration

Every IPH is fully tested and calibrated at the factory prior to shipment. Before installation, however, your IPH’s should be bench-checked to verify proper operating levels and to set the desired unit zero and unit span. Calibration should be conducted in an appropriate testing environment.

Necessary Equipment

Table 1 lists the equipment required to calibrate the IPH. This equipment is not supplied by Moore Industries, but should be available in most labs or maintenance areas.

Preparing for Calibration

To prepare the IPH for calibration, remove the screw-on cap and connect the unit to your calibration equipment as shown in Figure 1 on page 3, which shows the calibration setup.

Unit Connections and Controls. The IPH has two labeled terminals on its faceplate, located under the top protective cover of the housing. The terminal labeled “+I” is for connection of the positive current input, and the terminal labeled “–I” is for negative connections.

IPH

The two IPH controls are also located inside the unit housing under the screw-on cap. They consist of a mechanical adjustment screw and an electronic potentiometer, each accessed through the front panel. They are labeled “zero” and “span”. The zero adjustment screw mechanically provides a control range for zero offsets of ±3 percent of rated unit span.

The span pot electronically adjusts unit full-scale output to 100 percent of rated span. It requires approximately 22 turns to move its wiper from one extreme to the other, clockwise for maximum or counterclockwise for minimum span. It is equipped with a slip clutch to prevent damage if the adjustment is turned beyond the wiper stop.

Note: Always use clean, dry, instrument air when

calibrating or operating the IPH.

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

Calibration Steps:

(See Figure 1)

1. Orient IPH vertically or horizontally based on how it will be positioned in the application.

2. With zero air input (supply off), connect 1/4-inch pneumatic tubing between the appropriate output port of the regulated instrument air supply and the calibrated pressure gauge #1 (accuracy of ±2% of span). Connect another hose from the pressure gauge to the port labeled “IN” on IPH.

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

4. Run current source wiring through conduit opening in housing, and to front panel of IPH.

5. Connect positive lead of adjustable current source to +I terminal of IPH. Connect negative source lead to –I IPH terminal. A dc multimeter may also be connected to verify level of current input.

6. When connections are complete, apply 4mA of input current. (0% of total current)

7. Apply appropriate filtered, instrument-quality air to supply line: 20 or 35 psi (40 kPa, or 1.4 bar). Verify appropriate supply pressure by checking Supply Pressure field of unit model number.

8. Set span pot to approximately mid-scale (22 turns in either direction, then approximately 11 turns in the opposite direction).

9. Set zero adjustment screw fully clockwise, then five turns counterclockwise.

10. Allow approximately 30 seconds for calibration setup to stabilize.

Calibration Process

To perform the recommended bench-check for the IPH, first perform the setup as described in the preceding section. The calibration procedure consists of a basic check and adjustment of unit zero and span, based on the reading of pressure gauge #2 (accuracy of ±0.1%).

Table 2 lists the values to be used during calibration. Refer to the table when performing the following:

1. Check unit zero setting. Monitor reading of pressure gauge #2 (output), and turn zero adjust screw counterclockwise to lower output, clockwise to raise output. Set zero adjust screw so that pressure output is at 0% of appropriate range (±3%) when 0% input is applied.

2. Check unit span setting. Increase input to 100% of rated span (20 mA).

3. Monitor reading of pressure gauge #2 (output), and adjust span pot so that reading is at 100% of appropriate pressure range for your unit.

Check the values listed in Table 2.

4. Repeat steps 1 through 3 until IPH outputs 0% of rated pressure range at 0% current input, and 100% of output pressure range at 100% current input.

5. Verify the accuracy of your adjustments by inputting the appropriate percent of span levels listed in table 2.

IPH

Installation

The installation of the IPH is carried out in three phases. The first phase is the physical mounting of the unit. Next is the electrical connections phase, and finally, pneumatic connections can be made. It is strongly recommended that IPH’s be installed in this order. It is also strongly suggested that each unit be calibrated according to the instructions in this manual before being placed into service.

The IPH may be installed at any angle: either surfacemounted or attached to pipe or round conduit. When deciding on the placement of the IPH unit, make sure to consider the possibility of needing to: access the front panel, check the fittings, read the -FR1 Option gauge, or drain the filter.

Closed Loop/Open Loop. The IPH should be installed in a closed loop. A closed loop is the best way to measure a control variable. It also helps determine if a deviation from a desired value exists and provides feedback for actuator loading pressure.

An open loop has limitations that are not consistent with precise control. Long term drift of the loop dynamics, load fluctuations that require constant adjustments of the actuator loading pressure, and performance quality variations due to inconsistencies between operating personnel are all problems commonly associated with open loops. A controlled variable cannot be directly measured in an open loop; this prevents compensating adjustments to the system input.

Phase Two: Electrical Connections

To complete the electrical connections, route the wiring through the conduit port to the terminal block, then use a slotted-tip screwdriver with a maximum head width of 3 mm (0.125 inch) to loosen the terminal screws.

The terminals are comprised of compression-screw sockets that accommodate 22-14 AWG wiring.

Connect positive lead (+) to terminal labeled “+ negative lead (–) to terminal labeled “–I”. Tighten the

terminal screws until snug. Use shielded, twisted-pair wiring for low-level input.

Ground the shielding wire as close as possible to the installed IPH.

I”, and

Phase Three: Pneumatic Connections

To complete the final phase of installation, the pneumatic connections, connect the supply line to the 1/4-inch NPT female port labeled “IN”. Connect the output line to the 1/4-inch NPT female port labeled “OUT”.

Seal all fittings with Teflon® tape, or equivalent. Always “blow down” (purge) all tubing and the controlled device before connecting the IPH.

Filters. The IPH requires filtered, dry, regulated, instrument-quality air to prevent clogging and to ensure extended periods of maintenance-free operation. Moore Industries suggests the following levels of filtering protection:

Phase One: Mounting

Figure 2 gives the IPH’s outline dimensions. The illustration also gives the dimensions of the available

-FR1 Option hardware, which is recommended for most installations.

After placing the IPH in the desired location and orientation, secure the housing with the optional pipe mounting hardware or other appropriate fasteners.

If you have further questions on how to mount the IPH, contact your Moore Industries Sales Representative for assistance.

NOTE:

For NEMA4X and IP55 Installations, the unit must be

mounted vertically or within 45 degrees of vertical.

• Pre-filter – A general purpose “rough” filter, used to reduce particulate matter to 5 microns in size. Also removes bulk liquids. Although not required, this filter is especially recommended to protect the

0.01 micron final filter when used.

• Final Filter – A second, final filter is recommended, to remove particulate matter in sizes down to 0.01 micron. This filter removes virtually all condensable liquids from the air stream as well.

• Filter/Regulator Module Option – A combined filter/regulator assembly, the -FR1 Option, offered as an accessory for the IPH, removes particles down to 0.01 micron, supplying regulated, instrument-quality air to the unit. This space-saving module is affixed to the IPH supply port, and comes with a pressure gauge scaled in both psi (0-60) and bars (0-4).

IPH

Operation

Once the IPH unit’s calibration has been checked or adjusted and the unit has been installed properly, the IPH operates unattended with the exception of the minor maintenence procedures that are described in the next section.

Remember that if an IPH is installed in an open loop, it may appear to drift over extended periods of time because of the lack of corrective feedback.

If the unit is determined to be the cause of a loop irregularity, carry out the maintenance procedure in the next section of this manual. If problems persist, refer to the Troubleshooting Section.

Instrument-quality Air. Air from the application continuously flows through the IPH during operation. Depending upon the purity of the air supply, the unit’s internal assembly may have to be removed and cleaned to ensure continued optimum performance.

Initially, random checks can help establish a satisfactory maintenance interval geared to the user’s air supply cleanliness. Refer to the next section for instruction on the disassembly and cleaning of the IPH.

this equipment is not available, your facility may not be qualified to perform the operations described in this section. Contact Moore Industries’ Customer Service Department for more information.

Disassembling the IPH

To disassemble the IPH for maintenance/cleaning, unscrew the protective top cover, then unscrew the two screws from the base and remove the unit.

Take the internal assembly out of the housing by pulling straight out, away from housing base. Apply steady pull, disengaging the pneumatic fittings from their ports in the housing base. Do not disassemble the pneumatic block at this time.

Separate the faceplate from the transducer by removing the screws on both sides of the plate assembly.

Cleaning the Subassembly

1. Place subassembly on work surface with zero

screw and span pot down.

2. Use syringe to fill Orifice #1 with trichloroethane

(TCE). See Figure 3.

Maintenance

Before beginning IPH maintenance, the unit must be removed from its application.

Warning: It is strongly recommended that the

maintenance procedures be performed in a clean,

controlled environment, such as a technicians’

bench, a laboratory, etc. Several internal parts are

small and precision-machined and can be easily lost

or damaged if an attempt is made to perform

maintenance in the field.

After maintenance, each IPH should be recalibrated before it is returned to service. Refer to the Calibration Section of this manual for instructions.

Necessary Equipment

To perform the basic maintenance procedure for the IPH, refer to Table 3, which lists the required equipment. These materials are not supplied by Moore Industries, but should be available in maintenance areas prepared to perform this type of procedure. If

3. Clean nozzle air passage by gently passing

cleaning wire back and forth through opening in subassembly base.

4. Soak several small strips of clean paper in TCE.

5. Set the subassembly on its side and slide one strip

between the nozzle and the flapper. Carefully apply slight pressure to flapper until it rests against nozzle with soaked paper in between.

6. Maintain pressure while pulling paper out. Repeat

with other strips of paper until no residue is transferred to paper.

7. Inspect air passage O-ring. If damaged, contact

Moore Industries’ Customer Service Department for replacement.

8. Use instrument air supply to dry and generally

“blow out” subassembly. Put small amount of alcohol in air passage and set subassembly aside.

15. Locate the supply port air filter screen on the pneumatic block.

16. Remove filter screen with needle, and flush with TCE. Rinse with alcohol and set aside to dry.

Re-assembly

1. Dry all parts of the pneumatic block and the mechanical subassembly with the specified air or nitrogen supply. Make sure all parts are clean and dry.

2. Use the scratch markings made earlier to make sure that each section of pneumatic block is oriented properly, then use small socket-head screws to secure re-assembled block. Tighten screws to between 35 and 45 Nm of torque (26 to 33 ft/lbs).

3. Line up pin on section #1 of pneumatic block with hole on base plate of mechanical subassembly.

4. Place a small amount of thread-locker on the threads of the head screw used to hold the pneumatic block and mechanical subassembly together, and secure two subassemblies to each other with the screw. Make sure screw is as tight as possible.

Drain Check. System filters have automatic drains that depend on the fluctuation of system pressure to induce drainage. A stable system may not drain efficiently.

Check periodically for clogs and drain system’s filters by pushing the drainage valve with a small probe or wire.

Troubleshooting the IPH

Many components of the IPH have been thermally aged, tested, and selected using a computer-aided design program. This usually makes field repair unnecessary.

It is therefore recommended that any properly maintained unit found to be performing below specifications 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 IPH, review the following steps:

1. Verify that bench instruments used to take measurements have the proper range and accuracy and are within current certification period limits.

2. If a change in the relationship between the input and output is detected, attempt a re-calibration of the IPH.

3. If the response time lengthens, or if the span drops, this may indicate a blockage due to air supply contamination. Follow the instructions in the Maintenance Section of this manual.

5. Place mounting bracket over subassembly and pneumatic block and screw the bracket onto the subassembly.

6. Slide internal assembly into housing, being careful not to crimp or pinch the current wiring, and mate fittings in housing with ports on pneumatic block of internal assembly. Press down until locked into place.

7. Reseat the IPH and screw it in.

8. Calibrate unit. Refer to Calibration Section of this manual for detailed instructions.

10 The Interface Solution Experts

The Zero Adjust Screw. This screw has a flange to prevent its being turned too far counterclockwise during adjustment. Forcing the screw past the point at which its flange comes into contact with the unit front panel could disengage it from the internal assembly.

If this happens, disassemble the IPH as described in the Maintenance Section of this manual.

Visually inspect the screw, and if serviceable, hold down the flapper arm and turn the screw clockwise until its pin is in a position to hold the arm.

Refer to the Calibration Section of this manual, and recalibrate unit.

Installation Category

All of Moore Industries’ terminals are rated CAT II, except those with the -RF option. These terminals are rated CAT I.

Equipment Ratings

The IPH does not generate hazardous voltages, rather, it accommodates a current input, and generates a pressure output. Products connected to the IPH should be designed to receive these inputs.

Supply Wiring

All power connections should be made with the proper wire.

The end of each conductor should be stripped no more than 8mm. The end of the stripped wire should be tinned with solder, or inserted into a ferrule and crimped before being placed into a terminal block.

Conductors connected to screw-type connections should have a ring-lug or spade-lug crimped onto the wire end.
