1.1 Pre-Installation Requirements
1.1.1 Environment: Suitable for installation in the following locations:
 Intrinsically safe operation in hazardous locations outdoors (NEMA 4X, CSA.ENC.4 & IP65)
 See section 3.1, 3.2 and 3.3 for Factory Mutual (FM), Canadian Standards (CSA), ATEX and EU
approvals.
All wiring must be made to all local and national codes appropriate to the area of
installation.
1.1.2 Electrical Input: 4-20 mAdc current source or 0-5, 0-10, 1-5, 1-9 VDC voltage source depending on
model.
1.1.3 Air supply: Clean, dry, oil free instrument air filtered to 40 micron.
Clean all pipe lines to remove dirt and scale prior to installation. Failures attributable to
instrument air supply contamination are not covered by the warranty.
This instrument vents to atmosphere. The use of supply gas other than air can create a
hazardous environment.
1.2 Mounting
1.2.1 The Type 550X comes with a standard mounting kit that enables panel or wall mounting of the
unit. An accessory mount kit (P/N: 448-542-005) allows 1 ½” or 2” pipe mounting.
1.2.2 With access to the rear of a panel, attach transducer using two 10-32 screws and the two threaded
mounting screws on the back of the unit. With no access to the back of the panel, attach the bracket to
the transducer using the two 10-32 holes on the back of unit and mount bracket to panel using four 10-
32 screws (see figure 2).
1.2.3 To mount unit to a 1 ½” or 2” pipe, use two 10-32 holes on the back of the unit to attach bracket to
transducer. Then place U-bolt around pipe and through bracket. Place nuts on U-bolt and tighten (see
figure 1) (Accessory mount kit P/N: 448-542-005).
1.2.4 Due to its light weight, the Type 550X can also be mounted in line with support provided by the supply
and output piping.
1.2.5 Because of it’s small size, the Type 550X can easily be mounted to a manifold. ControlAir’s Type 925
multifunction supply manifold is designed for this purpose.
Shaded areas and associated dimensions apply to the zero based unit only.

1.2.6 The Type 550X can be mounted to DIN-rail using the optional kit, ControlAir part number
445-766-024. This will allow the transducer to mount to DIN 50045, 50035, 50022 rails (see figure 3).
Shaded areas and associated dimensions apply to the zero based unit only.
1.3 Pneumatic Connections
1.3.1 Clean all pipe lines to remove dirt and scale prior to installation.
1.3.2 Supply air must be filtered to 40 microns and free of moisture and lubricants.
1.3.3 Two (2) 1/4" NPT ports labeled IN are provided for supply air connections. Either port may be used.
The unused port must be plugged with the pipe plug included with the unit.
1.3.4 Two (2) 1/4" NPT ports labeled OUT are provided for pneumatic output connections. Either port may
be used and one may be used for the mounting of an output gauge. If no gauge is installed, the
unused port must be plugged with the pipe plug included with the unit.
1.4 Electrical Connections
1.4.1 Both the I/P and E/P versions of the Type 550X are two wire devices (do not require a separate power
source), plus a safety ground. The I/P unit requires a variable input current of 4-20 mA. The E/P
version requires a DC voltage input signal such as 0-10 VDC.
1.4.2 1/2" NPT conduit connection (A) is made using 18” pigtail wire coming from unit. For I/P (current to
pressure) versions, electrical connections are made to the red (+) and black (-) leads. The green lead
is furnished for case ground. For E/P (voltage to pressure) versions, electrical connections are made
to the red (+) and black (-). The green lead is furnished for case ground (see figure 4).

1.4.4 Terminal Block (T) Electrical connections are made to the positive (+) and negative (-) terminals. For
direct acting operation connect the positive side of the input signal to the (+) terminal
1.4.5 The use of shielded cable is recommended.
1.4.6 M12 (M) Electrical Connections are made to the positive (+) pin 2 and negative (-) pin 1. For direct
acting operation connect the positive side of the input signal to the (+) pin 2. Pin 4 is for case ground.
Pin 3 is not used.
NOTE No agency approvals apply for M12 connector.

2.1 Calibration
2.1.1 All units are shipped from the factory calibrated, direct acting.
Factory calibration is susceptible to shift due to handling during transit. ControlAir
recommends that all units be recalibrated prior to use.
2.1.2 Though the units are shipped fully calibrated it is suggested that the user check the calibration to
ensure that settings and operation match the application requirements.
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. Apply the minimum
input signal of the range being used (e.g. 4 mA for a 4-20 mA unit).
2.2.2 Observe the output pressure. If necessary, adjust the zero screw until reaching minimum output
pressure setting. Turn zero screw clockwise to increase and counter clockwise to decrease.
2.2.3 Apply the maximum input signal of the range being used (e.g. 20 mA for a 4-20 mA unit).
2.2.4 Observe the output pressure. If necessary, adjust the span screw until reaching maximum output
pressure setting.
2.2.5 After setting the span it will be necessary to recheck the zero. Repeat steps 1-4 until both end points
are at required values.
2. OPERATION
NOTE
The unit must be calibrated in the plane it is mounted in.
NOTE
NOTE
NOTE
If unable to achieve output during the calibration process, follow the steps
outlined in 4.1.4. to clean the orifice. Then turn the zero adjustment screw
clockwise slowly and carefully until output pressure begins to respond.
The unit must be calibrated in the plane it is mounted in.
For I/P (current) input models, turn span screw clockwise to increase pressure,
counter clockwise to decrease pressure. For E/P (voltage) input models, turn span
screw clockwise to decrease pressure, counter clockwise to increase pressure.

4.1 Instrument Air Filtration
4.1.1 Failures due to instrument supply air contamination are not covered by warranty.
4.1.2 Use of oil and/or water saturated instrument air can cause erratic operation.
4.1.3 Poor quality instrument air can result in unit failure. It is recommended that a filter regulator (such as
ControlAir Type 300) be placed upstream of each unit where oil and/or water laded instrument air is
suspected.
4.1.4 If clean, dry air is not used the orifice can become blocked. To clean, first turn off supply air, then
remove the screw located on the side of the unit above the “out” port. The orifice is a very small hole
on the side of the screw. Unplug the orifice using a wire that has a smaller diameter than 0.012”
(0.30mm). Replace screw tightly into unit.
