This Quick Start Setup guide can be used by experienced instrumentation technicians to configure the
Transmitter using the Zero and Span push-buttons or via the optional Hart Communications. For more
detailed information please consult the complete manual before operating. The Quick Start procedure
with Hart is designed for users already familiar with the use of the Hart Communicator and loop powered
instrumentation.

1. Insure the mounting hole is clear of any frozen polymer or debris and is machined to the proper
dimensions. Apply a quality high temperature Anti-Seize lubricant to the snout tip threads. For
flanged configuration units, apply Anti-Seize to mounting bolt threads and use proper Buttonseal
gasket and install on transducer snout. Install unit into the process connection. (Do NOT torque
transmitter into the hole at this time!) Allow time for the transmitter snout temperature to
equalize to the process temperature. This will help eliminate thread galling and ease removal
later. There should be NO pressure applied at this time.
2. Connect power to the transmitter. For a 2 wire conduit output configuration, Red wire is Sig+/Exc +,
Black wire is Sig-/Exc-, Green wire is Ground. For a 6 pin connector version, Pin A is Sig+/Exc+ and
pin B is Sig-/Exc-. Insure proper loop supply voltage is applied to transmitter.
3. After temperatures have equalized, apply proper torque as described in Section 5.2 of the Manual
and tighten transmitter into mounting hole.
In hazardous areas do NOT remove screws when circuit is live.
4. Remove zero push-button seal screw.
5. To perform a Zero Calibration, use a 2 mm or smaller allen key and insert into push-button hole to
make contact with push-button at the bottom. Depress the button for 1/2 second, release, then
push again for 1/2 second.
6. Verify loop output is zero (4 mA).
7. Replace the Seal Screw.
Seal screw must remain in place to retain Explosion Proof certification.

The mechanical system (filled assembly) consists of a lower diaphragm, a filled capillary tube, and an
upper diaphragm with a strain gage. The filled assembly transmits pressure from the process to the strain
gage diaphragm where it is converted to an electrical signal. The filled assembly isolates the electronics
from the high process temperatures.
The lower diaphragm is the surface in contact with the media being measured. This diaphragm can be
made from a choice of materials. The standard material is heat-treated 15-5 stainless steel with DymaxTM
coating. This has average corrosion and abrasion resistance and is similar to 17-4 stainless steel. Other
materials are also available including Hastelloy C-276 which has excellent corrosion resistant properties
(but is not good for abrasion). For other materials please consult the factory.
Behind the lower diaphragm is a capillary tube filled to the upper diaphragm. As the process pressure
deflects the lower diaphragm, the fill is displaced through the capillary tube to deflect the upper
diaphragm.

GENERAL
The upper diaphragm has a strain gage element in the configuration of a Wheatstone Bridge. The
deflection of the upper diaphragm causes a change in the resistance of the strain gage and hence a
change in the balance of the bridge. The amount of imbalance is directly proportional to the applied
pressure. This completes the translation of pressure applied to the lower diaphragm into a usable
electrical signal.

The low level output signal from the bridge is amplified via an instrumentation amp circuit. The amplified
signal then goes to the input of the analog-to-digital (A/D) converter.
Once the microprocessor has the converted voltage input from the A/D converter, the digital signal is
sent to a digital-to-analog (D/A) converter which modulates the current of the unit’s power supply
between 4 and 20 milliamperes for an output current proportional to the applied pressure.

When using the SPX as a safety component in accordance with the EC Machine Directive,
Annex IIc, the equipment manufacturer must take any necessary precautions to ensure
that malfunction of the PT cannot cause damage or injury.
The installation of the device must be in accordance with European installation guidelines
EN 60079-10. Over voltage protection shall be implemented as mentioned in EN 60079-14.
When planning machinery and using the SPX, follow the safety and accident prevention regulations that
apply to your application, such as:
•EN 60204, Electrical equipment in machines
•EN 292, Machine safety, general design guidelines
•DIN 57 100 Part 410, Protection against electric shock
•EN 50014:1997 incl. Amendments A1, A2 General requirements
•EN 50020:2002 Intrinsically Safe Apparatus
