PRINCIPLE OF OPERATION

The transducer is a force balance device in which a coil is suspended in the field of a magnet by a flexure. Current flowing through the coil
generates axial movement of the coil and flexure. The flexure moves against the end of a nozzle, and creates a back pressure in the nozzle by
restricting air flow. This back pressure acts as a pilot pressure to an integral booster relay. Consequently, as the input signal increases (or
decreases, for reverse acting), output pressure increases proportionally. Zero and span are calibrated by turning easily accessible adjusting
screws on the front face of the unit. The zero adjustment causes the nozzle to move relative to the flexure. The span adjustment is a
potentiometer that limits the flow of current through the coil. A thermistor circuit in series with the coil provides temperature compensation.

MOUNTING

The transducer can be mounted at any angle, but should be
calibrated after mounting. For maximum output pressure
stability, it should be mounted vertically in a vibration free
location or such that the vibration is isolated to the X and Z

.

axis as shown in Figure 3.

Pipe: Due to its light weight, the transducer may be sup­ported by the piping used for the supply and output.

Panel: (with access to rear of panel) Attach transducer (See
Fig. 3), to panel using two 10-32 screws and two threaded

mounting holes on the back of the unit.

Panel: (with no access to rear of panel) Attach bracket (See
Fig. 1 and 3), to transducer using two 10-32 screws on the

back of the unit and mount bracket to panel using four 8-32
screws.

AIR CONNECTIONS

Ÿ Supply Air must be instrument quality air regulated

Figure 1

between the minimum and maximum specified on the
nameplate of the transducer.

Ÿ Instrument quality air consists of:

a A dew point less than 35˚F

b No particles larger than three microns
c Maximum oil content of 1 ppm

Ÿ All unused ports must be plugged.

Supply: Connect supply to the 1/4" NPT ports marked “IN” on the base of the transducer. Avoid getting pipe sealant inside the piping or
transducer.

Output: Connect output to the 1/4" NPT ports marked “OUT” on the base of the transducer. The pipe plugs may be removed from the two
auxiliary output ports for a pressure gauge or as an alternative output port.

INSTALLATION OF THE DIN 43650A CONNECTOR

Included with the unit: Instructions & 3-Prong Connector
Tools Required: Solder, Soldering Iron & Wire Cutter/Stripper

1. Remove the outer locking ring from the male portion of the DIN 43650A connector and disassemble.

2. Run the two wires through the NPT portion of the male connector and thread the connector snugly into the ½ NPT conduit port.

3. Cut both wires (black and white) to about 1” long beyond the male NPT section that is installed on the IP210A, and trim the end to
about 1/4”.

4. Solder the black wire to Pin #1, and the white wire to Pin #2.

5. Insert the terminal portion into the NPT portion.

6. Position the prongs with the Safety Ground (flat prong) on the bottom. Secure with the outer ring. Do not overtighten.

7. Remove the terminal portion of the female section of the connector using a small slotted screwdriver under the slot marked “LIFT”.

8. Run wires through the connector housing and secure to the appropriate terminal with a small screwdriver.

For DIRECT ACTING: (where increasing the input signal increases output pressure), connect the positive input signal to Pin #1, and

the negative to Pin #2.

For REVERSE ACTING: (where increasing the input signal decreases output pressure), connect the positive input signal to Pin #2,
and the negative to Pin #1.

9. Insert the terminal into the housing with the proper wiring orientation.

10. Orient the gasket over the prongs, and install the female portion of the connector assembly. Using a small screwdriver, secure with
the locking screw.

ELECTRICAL CONNECTIONS

PRECAUTIONS TO BE OBSERVED DURING INSTALLATION

The Transducers were tested at the EMC Test Centre, Dunfermline, Fife, KY11 5LB to the Electromagnetic Compatibility
Directive effective January 1, 1996. The relevant EMC specifications tested were the following: EN 50081-1 (1992) and EN
50082-1 (1992). A Technical Construction File, Serial #107 was written and Certificate of Conformity issued by a Competent
Body.

EN 50081-1 (1992): Test results confirmed that no precautions need to be observed during installation regarding electro-magnetic
emissions from the IP210A Transducers.

EN 50082-1 (1992): The following precautions should be taken during installation to maintain the advertised accuracy specifications for the
Transducers. The input wiring to the transducer should be isolated from other high voltage transient wiring. The momentary switching on
and off of nearby relays, motors, or other high capacitive or inductive loads can have a minor effect on the terminal based linearity
specification (1.0% of span, standard range models). Any change in output pressure is minimal and momentary, and is considered to be
within its performance capabilities. Use of a ferrite bead collar on the input wires entering the transducer is recommended should
installation next to high electromagnetic interference be necessary.

ALIBRATION

C

M5736/0619 IP210A SERIES

Once the transducer has been mounted, and air supply connections finished, the unit's calibration must be checked before placing into
service. Remove rubber plugs to gain access to “ZERO” and “SPAN” adjusting screws. See Figure 3 for “ZERO” and “SPAN” locations. Re­install rubber plugs after calibration is complete.

Note: input percentage refers to the following examples:

If 4 to 20 mA

0% = 4 mA

25% = 8 mA
50% = 12 mA
75% = 16 mA

100% = 20 mA

Forward Acting

1. Apply the 0% input signal to unit and adjust the “Zero” adjusting screw to the low setpoint output. Turn screw counter-clockwise to
increase output. If there is no change in output, keep turning adjustment screw counter-clockwise until output begins to rise. It is
imperative that the output pressure be closely monitored as turning the zero screw excessively could damage the flexure.

2. Apply the 100% signal to unit and adjust “Span” adjusting screw until output is at the high setpoint.

3. Turn the “Span” adjusting screw counter-clockwise to increase output.

4. Repeat steps 1& 2 until unit is calibrated.

Reverse Acting

1. Apply the 0% input signal to unit and adjust "Zero" adjusting screw until output reaches the high output pressure set-point. Turn
counter-clockwise to increase.

2. Apply the 100% input signal to unit and adjust "Span" adjustment until output pressure is at the low setpoint.

IMPORTANT: Turn the “Span” adjusting screw clockwise to increase output

3. Repeat steps 1& 2 until unit is calibrated.

SIGNAL IMPEDANCE

The input impedance will vary depending upon the potentiometer setting of the “SPAN (RV1)”, (SEE FIG. 2). The I/P circuit design consists
of a resistor and potentiometer in parallel with the coil/flexure. The following are some of the nominal impedences that would be measured
across the signal leads of the average calibrated transducer. These values are helpful when determining power requirements and for
troubleshooting.

INPUT SIGNAL OUTPUT RANGE

4-20mA 3-15 PSIG 180 1000
4-20mA 3-27 PSIG 215 1000
