1.0 General Information

Every Model 206 has been tested and calibrated before shipment.
Performance specications are shown on page X of this guide.

Setra Systems Model 206 pressure transducers sense gauge and vacuum

pressure and convert this pressure dierence to a proportional high level
analog output. Two standard output and excitation versions are oered:

Excitation Output

9 to 30 VDC 4 to 20 mA (must observe polarity)

12 to 28 VDC 0.1 to 5.1 VDC (reverse wire protection up to 22VDC

excitation to the output lead

2.0 Mechanical Installation

2.1 Media Compatibility

Model 206 transducers are designed to be used with any gases or liquids

compatible with 17-4 PH stainless steel.

2.2 Environment

The operation temperature limits of the 206 are -40° to +260°F (-40 to

+127°C).

The compensated temperature range is -4 to +176°F (-20 to +80°C).

2.3 Pressure Fittings

Typically, standard pipe ttings and procedures should be used. However,

for pressure ranges in excess of 500 PSIG (35 Bar) we suggest the use of a
sealant such as Loctite Hydraulic Sealant. Excessive torquing of metal t­tings may cause a slight zero shift. The use of plastic ttings typically results
in no noticeable zero shift. Torquing does not appreciably aect linearity or
sensitivity.

2.4 Venting

The reference pressure in a sealed gage transducer will vary due to changes

in temperature, atmospheric pressure, humidity, etc. This change aects
the overall accuracy of the unit. To compensate all gage and compound
206 units are vented to atmosphere using the following methods based on
the electrical termination used.

6.0 Warranty & Limitation of Liability

SETRA warrants its products to be free from defects in materials and work­manship, subject to the following terms and conditions: Without charge,
SETRA will repair or replace products found to be defective in materials or
workmanship within the warranty period; provided that:

a) the product has not been subjected to abuse, neglect, accident, incor-

rect wiring not our own, improper installation or servicing, or use in
violation of instructions furnished by SETRA;

b) the product has not been repaired or altered by anyone except SETRA or

its authorized service agencies;

c) the serial number or date code has not been removed, defaced, or oth-

erwise changed; and

d) examination discloses, in the judgment of SETRA, the defect in materials

or workmanship developed under normal installation, use and service;

e) SETRA is notied in advance of and the product is returned to SETRA

transportation prepaid.

Unless otherwise specied in a manual or warranty card, or agreed to in writ­ing and signed by a SETRA ocer, SETRA pressure and acceleration products
shall be warranted for one year from date of sale.

The foregoing warranty is in lieu of all warranties, express, implied or statu­tory, including but not limited to, any implied warranty of merchantability for
a particular purpose.

SETRA’s liability for breach of warranty is limited to repair or replacement, or
if the goods cannot be repaired or replaced, to a refund of the purchase price.
SETRA’s liability for all other breaches is limited to a refund of the purchase
price. In no instance shall SETRA be liable for incidental or consequential

5.0 RETURNING PRODUCTS FOR REPAIR

Please contact a Setra application engineer (800-257-3872, 978-263-1400)
before returning unit for repair to review information relative to your ap­plication. Many times only minor eld adjustments may be necessary. When
returning a product to Setra, the material should be carefully packaged and
shipped prepaid to:

Setra Systems, Inc.
159 Swanson Road
Boxborough, MA 01719-1304
Attn: Repair Department

To ensure prompt handling, please supply the following information and
include it inside the package or returned material:

• Name and phone number of person to contact.

• Shipping and billing instructions.

• Full description of the malfunctions.

• Identify any hazardous material used with the product.

Notes: Please remove any pressure ttings and plumbing that you have installed and

enclose any required mating electrical connectors and wiring diagrams.

Allow approximately 3 weeks after receipt at Setra for the repair and return of

the unit. Non-warranty repairs will not be made without customer approval
and a purchase order to cover repair chargers.

Cable Termination and Hirschmann Models

All 206 models with a cable termination or Hirschmann connector vent

through the cable to maintain proper accuracy. Connection to the unit
should be made in a junction box that is vented to atmosphere, with care
taken to ensure that the end of the cable is not blocked or sealed.

The following junction box conguration is a recommended method

for connecting to 206 units in order to achieve a moisture resistant and
vented connection.

Calibration Services

Setra maintains a complete calibrations facility that is traceable to the
National Institute of Standards and Technology (NIST). If you would like
to recalibrate or recertify your Setra pressure transducers or transmitters,
please call our Repair Department at 800-257-3872 (978-263-1400) for
scheduling.

• Drill one ½” dia. Hole at each of the junction box for cable strain reliefs.

• Drill and tap one ½” – 13 NC hole in bottom of junction box and install
loosely one ½” – 13 NC plastic or stainless steel screw. The clearance
between threads serves as ventilation.

• Install cable strain reliefs in ½” holes.

• Mount junction box and install cables.

• A desiccant pack can be placed in the junction box for additional hu­midity protection.

Notes: The above directions are for cable termination models. Hirschmann and
conduit connections require slight modications at the discretion of the installer.

Terminal Block Connections

All 206 models with terminal block connections are vented through a

porous plug on the connected; no additional venting is required during

installation.

3.0 Electrical Installation

The model 206 is available in the following electrical terminations:

• 2 foot cable (additional length available)

• 3-screw terminal block

• Hirschmann connector

• 1/2” conduit

3.1 Voltage Output Units

Wiring for cable, Hirschmann and conduit model 206 transducers with voltage
output is as follows:

3.2 Current Output Units

Current output model 206 are true 2-wire, 4-20 mA current output devices
and deliver rated current into an external load of 0-800 Ω. Cable termina­tion models have a 2-wire cable where red is positive and black is negative.
On the Hirschmann connecter, pin 1 is positive; pin 2 is negative and pin 4
is the ground/shield. Terminal block units have outputs label + for positive
and – for negative, the center terminal may be used for shielding.

Note: All 4-20 mA current output units are designed to have current ow in one direction only- PLEASE OBSERVE
POLARITY. We suggest that the electrical cable shield be connected to the system’s loop circuit ground to improve

electrical noise rejection.

4.0 CALIBRATION

Every model 206 is factory calibrated and should require no eld adjust­ment. Whenever possible, any zero and/or span osets should be corrected
by software adjustments in the user’s control system. However, both zero
and span adjustments are accessible by removing the pan head screws and
turning the zero and span potentiometer screws inside. Pan Head screws
should be replaced after adjustment to maintain enclosure rating.

Cable & Conduit Hirschmann Pin Designation Connection to electrical system

Red #1 +Excitation; connect to 12-28 VDC power supply.

Green #3 +Output; connect to controller or monitor.

White #2 - Output; connect to controller or monitor.

Black #2 -Excitation; connect to return of 12-28 VDC power supply.

Shielding #4 Connect to system or earth ground.

Note 1: Model 206 can be wired as a three wire device by connecting -output and –excitation and shield to a common
ground. However, accuracy will be reduced because of voltage drops in the leads.

Note 2: Mating Hirschmann connects #GDM3009J, Hirschmann #932214-100 with GDM3-16 Hirschmann Gasket
#731531-002 are not provided by Setra Systems, unless ordered separately as an option.

Voltage output Model 206 with a 3 screw terminal block have excitation, out-

put and common termination pouts clearly marked, wiring is as follows.

Voltage output units are factory calibrated into a 50 KΩ load. Voltage units
are operable into a 5000 Ω load or greater. The zero factory setting is ±50

mV.

Current outputs units (4-20 mA) are factory calibrated with a 24 VDC loop to
supply voltage and a 250 Ω load. The zero factory setting is ±0.08 mA. The
span (full scale) factory settings is ±0.16 mA. Zero and span adjustment are
approximately ±1.0 mA.
