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.

Pre-installation Requirements

Environment: Suitable for installation in intrinsically safe operation in
hazardous locations outdoors (NEMA 4X, CSA.ENC.4 & IP65).

WARNING

ppropriate to the area of installation.

a

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.

anel Mounting

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).

DIN Rail Mounting Kit

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).

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

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

calibrated prior to use.

Factory calibration is susceptible to shift due to handling during
transit. Dwyer Instruments, Inc. recommends that all units be

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.

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.
