1. DESCRIPTION and INSTALLATION  
1.1 Description  
1.1.1 The Omega IP710 converts a current input signal to a linearly proportional pneumatic output pressure. This unit  
utilizes a closed loop pressure feedback system that closely controls output and compensates for vibration,  
mounting angle, temperature and supply pressure variations. The control mechanism is a piezoceramic actuator.  
The unique properties of this actuator protect it against moisture and breakage associated with similar competi-  
tive technologies.  
1.2 Principle of Operation  
1.2.1 The IP710 transducer is a force balance device in which the piezo actuator is positioned in relation to a nozzle as the  
input signal is varied. The application of an electrical signal causes axial movement of the actuator. The actuator  
moves toward the nozzle and creates back pressure which acts as a pilot pressure to an integral booster relay.  
1.3 Mounting  
1.3.1 Each IP710 comes with a mounting kit which enables pipe, panel or wall mounting of the unit. An optional mount-  
ing kit is available for DIN-rail mountings. The IP710 may be mounted at any angle.  
1.3.2 Panel: With access to rear of panel, attach transducer to panel using two 10-32 screws and the two threaded  
mounting holes on the back of the unit. With no access to the rear of a panel, attach bracket to transducer using  
two 10-32 holes on the back of the unit and mount bracket to panel using four 10-32 screws (see figure 1).

1.3.3 In- Line: Due to it’s light weight, the IP710 may be supported by the piping used for supply and output.  
1.3.4 11/2” Pipe: Attach bracket to transducer using two 10-32 holes on the back of unit. Place U-bolt around pipe and  
through bracket. Place nuts on U-bolt and tighten (see figure 2).

2. OPERATION  
2.1 Calibration  
2.1.1 All units are shipped from the factory calibrated, direct acting.  
2.1.2 If the user requires a different mode of operation (i.e. reverse acting, split range) it is necessary to reposition inter-  
nal electrical switches as indicated below. Though the units are factory calibrated for direct acting it is suggested  
that the user check the calibration.  
2.1.3 It is not necessary to remove the cover of the unit for calibration if the direct acting mode is desired.  
2.2 Direct Acting Calibration  
2.2.1 In direct acting operation the unit is calibrated so that minimum input signal corresponds to minimum output  
pressure and increasing input signal results in increasing output pressure.  
2.2.2 Apply the minimum input signal of the range being used (e.g. 4mA for a 4-20mA unit) (see figure 6).  
2.2.3 Observe the output pressure. If necessary, adjust the zero screw until reaching minimum output pressure setting.  
Turn zero screw clockwise to decrease and counter clockwise to increase.  
2.2.4 Apply the maximum input signal of the range being used (e.g. 20mA for a 4-20mA unit).  
2.2.5 Observe the output pressure. If necessary, adjust the span screw until reaching maximum output pressure setting.  
Turn span screw clockwise to decrease and counter clockwise to increase.  
2.2.6 After setting the span it will be necessary to recheck the zero. Repeat steps 1-4 until both end points are at  
required values.

Page 6  
 
2.3 Reverse Acting Calibration  
2.3.1 When calibrated to operate in the reverse acting mode the minimum input signal produces the maximum output  
pressure and increasing the input signal results in decreasing the output pressure. Setting the unit to operate in  
the reverse acting mode is accomplished by positioning internal electrical switches.  
CAUTION  
Do not reverse the input leads.  
2.3.2 Disconnect input signal and supply pressure. Take off the top cover by removing the four screws.  
CAUTION  
Avoid touching circuit board. Shorting possible.  
2.3.3 Position switches as illustrated in figure 8. Replace cover.  
2.3.4 Set the input signal to the minimum valve being used. Turn the zero screw to set the maximum output pressure.  
2.3.5 Set the span by applying the maximum input signal. Turn the span screw to set the minimum output pressure.  
2.3.6 It may be necessary to repeat steps 2.3.4 – 2.3.5 until both end points are at desired values.  
Figure 8 - Position of switches for Reverse Acting Operation  
Note: Switches not shown match Direct Acting Settings (see figure 7).  
2.4 Split Range  
2.4.1 When calibrated to operate in the split range mode, a full input signal (i.e. 4-20mA) will operate the unit  
at one half the normal output span (i.e. 3-9 psig, 9-15 psig). Setting the unit to operate in the split range  
mode is accomplished by positioning internal electrical switches.  
2.4.2 Disconnect input signal and supply pressure. Take off the top cover of the unit by removing the four screws.  
CAUTION  
Avoid touching circuit board. Shorting possible.  
2.4.3 Position switches as illustrated in figure 9. Replace cover  
2.4.4 After setting switches, refer to the appropriate calibration procedure (Direct Acting or Reverse Acting) to get to  
desired output range (i.e. 3-9 psig, 9-15 psig).

3. MAINTENANCE AND REPAIRS  
NOTE  
Under normal circumstances, no maintenance should be required.  
3.1 Cleaning  
3.1.1 If clean, dry air is not used the orifice can become blocked. To clear, first turn off supply air, then remove the  
screw located under the zero adjustment. The orifice is located between the two black o-rings. You may need a  
magnifying glass to see it. Unplug the orifice by running a wire that has a smaller diameter than 0.012” (0.30mm)  
through it.  
3.1.2 Used compressed air to blow out any loose particles inside the orifice screw assembly.  
3.2 Precautions  
3.2.1 The bonnet should be removed only if a different operation mode is desired which requires a change in circuit  
board switch settings. In this case, precautions are necessary.  
3.2.2 Never handle circuit board unless properly grounded to prevent ESD (Electro-static Discharge).  
3.2.3 If ESD grounding equipment is not available, hold the IP710 by its castings and adjust switches using a non-con-  
ductive devise such as a pencil or a small rubber handled screwdriver.  
3.2.4 Never remove circuit board for any reason. This will shift other components and possibly damage the pressure  
sensor, both cases resulting in malfunction.  
3.2.5 Use caution when replacing bonnet. If any resistance is felt, remove bonnet and determine the interference.  
Typically it will be the strain relief grommet on the wires. The grommet should be oriented so it sits beside the  
switches.  
3.2.6 Clean, dry air should be used with the IP710. Foreign matter in the supply line can clog the orifice openings.  
(.013” for a 3-15 psig unit, smaller for higher range units.) Foreign matter can also collect on the actuator causing  
erratic operation. Moisture in the supply line can damage circuit board components.  
3.2.7 The electrical specifications as outlined in the IP710 instructions must be complied with. If more than one IP710  
mA unit is driven by the same PLC, there must be a minimum of 9.5 v DC available to each unit. For a IP710 volt-  
age unit, there must be a constant supply voltage of 7-30 v DC applied to the red wire. The variable control volt-  
age is applied to the orange wire.  
3.2.8 If difficulty is experienced during calibration or if turning the zero or span screw has no effect on the unit, a reset-  
ting technique can be taken. Turn both the zero and span screw a minimum of 30 revolutions in one direction.  
Then turn both screws exactly 15 revolutions in the opposite direction. This procedure will put the potentiometers  
at their midpoint of effective adjustability. Next, calibrate to desired settings starting with the zero screw.  
3.2.9 Reverse Acting Mode: For reverse acting units, the zero adjustment refers to the minimum electrical signal and  
maximum output pressure. The span refers to the maximum signal and the minimum output pressure. For calibra-  
tion in reverse mode the resetting technique can be taken if necessary and calibration should always begin with  
the zero screw.

FAILURE MODES: This device must not be used for protecting final control elements connected to the output port from the effect of  
pressure present at the supply port. If devices connected to the output port have a pressure rating less than the pressure present at  
the supply port, then pressure relieving or pressure limiting devices must be employed to protect the devices from over pressuriza-  
tion, possibly causing physical damage, personal injury and/or property damage.
