Specifications - Installation and Operating Instructions
Bulletin V-3
The Series 2700 Current to Pressure Transducer is an electronic
pressure regulator that converts a current signal to a proportional pneumatic output. Its compact housing, accessible ports and easy adjustments provide an ideal answer to applications that are space­constrained. The NEMA 4X enclosure enables the unit to be installed indoors or outdoors, however, the unit is not vibration resistant. It is FM and CSA approved for intrinsically safe operation. The 2700 is designed for remote or panel mounting. This economical instrument provides precision air pressure regulation to actuators, valves, positioners and other final control elements. An integral volume booster provides high flow capacity, increasing control speed in critical applications. Other features include external zero and span adjustments which are convenient for field calibration.

Electrical Input: 4-20 mA DC current source. Air Supply: Clean, dry, oil free instrument air filtered to 40 micron.
OTICE
N
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.
CAUTION
This instrument vents to atmosphere. The use of supply gas other than air can create a hazardous environment.
Mounting
The standard mounting kit enables panel or wall mounting of the unit. For 1-1/2˝ and 2˝ pipe mounting, use the optional kit that is Dwyer Instruments, Inc. part number A-182.
To mount unit to a 1-1/2˝ 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).
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 the unit and mount bracket to panel using four 10-32 screws (see Figure 2).
Due to its light weight, the Series 2700 can also be mounted in line with support provided by the supply and output piping.

P
The Series 2700 can be mounted to a DIN-rail using the optional kit that is Dwyer Instruments, Inc. part number A-181. This will allow the transducer to mount to DIN 50045, 50035, 50022 rails (see Figure 3).

Pneumatic Connections
Clean all pipe lines to remove dirt and scale prior to installation. Supply air must be filtered to 40 microns and free of moisture and lubricants. Two (2) 1/4˝ NPT ports 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. Two (2) 1/4˝ ports are provided for pneumatic output connections. Either port may be used and one may be used for the mounting of an output gage. If no gage is installed, the unused port must be plugged with the pipe plug included with the unit.
Electrical Connections
The Series 2700 is a two wire device (does not require a separate power source), plus a safety ground. The unit requires a variable input current of 4-20 mA. The 1/2˝ NPT conduit connection is made using 18˝ pigtail wire coming from the unit. Electrical connections are made to the red (+) and black (-) leads. The green lead is furnished for case ground (see Figure 4).

TROUBLESHOOTING
Problem
No or low output
Look For
Zero Adjustment Supply pressure too low
Solution
Reset zero Increase supply pressure
(see specs) Unstable/low output Erratic Operation Works in reverse Output equals supply pressure
Electrical connection Clogged orifice Liquid/contamination in air supply Pressure goes down when signal is increased Improper pneumatic connections
Check connection/signal
Clean orifice
Clean air supply
Reverse input wires
Insure that supply is
connected to “IN” port
and output is connected
to “OUT” port
Apply the maximum input signal of the range being used (e.g. 20 mA). Observe the output pressure. If necessary, adjust the span screw until reaching maximum output pressure setting.
NOTICE
Turn span screw clockwise to increase and counter-clockwise to decrease.
After setting the span it will be necessary to recheck the zero. Repeat steps 1-4 until both end points are at required values.

Instrument Air Filtration
Failures due to instrument supply air contamination are not covered by warranty. Use of oil and/or water saturated instrument air can cause erratic operation. Poor quality instrument air can result in unit failure. It is recommended that a filter regulator (such as Dwyer Instruments, Inc. Series AFR) be placed upstream of each unit where oil and/or water laden instrument air is suspected.
OPERATION Calibration
All units are shipped from the factory calibrated, direct acting.
NOTICE

Factory calibration is susceptible to shift due to handling during transit. Dwyer Instruments, Inc. recommends that all units be
NOTICE
The unit must be calibrated in the plane it is mounted in.
Direct Acting Calibration
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).
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.
NOTICE
output pressure rises.
If unable to achieve output during calibration process, turn zero adjustment screw clockwise for up to 30 revolutions or until
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. Unplug the orifice using a wire that has a smaller diameter than 0.012˝ (0.30 mm). Replace screw tightly into unit.
