1. GENERAL INFORMATION
1.1. INTRODUCTION
This manual provides guidance for the installation, operation, and maintenance of your P+F Multiplexer
2700 and termination board. The solution herein is specifically designed for easy Multiplexer integration with
the Triconex TRICON system. Below is a list of termination boards and the Triconex I/O modules with which
they were designed to interface.
HPTB/32/TR-AO-01 3805E
The P+F Multiplexer 2700 will be referred to in this manual as the MUX 2700. All further general references
to the listed termination boards will be simply HPTB. When referring to the combination of a MUX 2700 and
an HPTB, they will be called the HART Interface Solution, or simply HIS.
1.1.1. SYSTEM OVERVIEW
Your HART Interface Solution interfaces up to 32 field located HART devices. The MUX 2700 is a HART
signal multiplexer unit which allows access to HART communications on existing 4-20mA wiring. It acts as
a gateway device routing communications between the maintenance workstation PC and the HART
devices. The MUX 2700 uses Manchester encoding of the HART protocol for the RS-485 link to the
maintenance workstation PC. To link to each of the HART devices the MUX 2700 communicates using Bell
202 Frequency Shift Keying (FSK). It interrogates each HART device, retrieves device information, and
stores it in an internal database. This information is available to the maintenance workstation software. In
this way, the MUX 2700 gives the user access to each HART device as if connected directly at the device
itself. A maintenance workstation PC can use this information for configuration, maintenance, calibration,
diagnostics, and data access.
The termination board design allows the DCS and field device wiring to be brought together with the MUX to
complete the system. Various HPTB board designs allow interface with different I/O cards and may include
configurable options including fused / filtered signal lines, loop or device powered instrument lines and 4-
20mA or 1-5 VDC signals. HART Interface Solutions are supplied by P+F in several models in order to
allow simple and reliable connection between SMART devices and various DCS systems.
1.1.2. HART OVERVIEW
HART is an acronym for "Highway Addressable Remote Transducer". The HART protocol makes use of the
Bell 202 FSK standard to superimpose digital signals at a low level on top of the 4-20mA signal. This
enables two-way communication and makes it possible for additional information beyond just the normal
process variable to be communicated to/from a SMART field instrument. The HART protocol allows a host
application (master) to get two or more digital updates per second from a field device. As the digital FSK
signal is phase continuous, there is no interference with the 4-20mA signal.
1.1.3. ASSET MANAGEMENT SOLUTIONS (AMS) SOFTWARE OVERVIEW
AMS software provides an easy-to-use means for integrating various device management software
packages into a unified system. AMS operates under the Microsoft® Windows® format. It combines the
various device (or asset) management tasks into an application with a common look-and-feel and
centralized data storage.
AMS provides access to functionality available via the HART communications protocol for any HART device
whose Device Description (DD) is registered with the HART Communication Foundation.
For more information on installation of AMS software, consult the AMS Installation Guide.

1.3. QUALITY ASSURANCE
Pepperl+Fuchs is an ISO9000 certified company and as such all production is performed under a Quality
Assurance program following written procedures which are specific for each product family. During the
manufacturing, intermediate testing and inspection, and final inspection phases all products are built
according to controlled documentation.
Each MUX 2700 unit undergoes accelerated thermic aging (burn-in) for a minimum 200 hours at 50°C
(122°F) with at least 1 cooling thermic cycle at 0°C (32°F) and back to 50°C (122°F). The purpose is to
identify weak components that may develop initial fault mechanisms due to "Infant Mortality". Only after a
positive burn-in test does the MUX 2700 undergo a complete final inspection which is performed with
computerized testing equipment specifically developed by P+F for this purpose.
1.4. SAFETY INTEGRITY LEVEL (SIL)
The following is assumed for SIL installations:
1.) Loss of 24V supplies results in 4-20mA loop going to 0mA and field devices going to safe state.
2.) A short in the 4-20mA loop will result in field device going to safe state, DCS would need sensor at field
device to know of short.
3.) An open in the 4-20mA loop will result in the field device going to safe state. DCS will know loop is open
since it can’t regulate current.
4.) DCS system will not produce an accurate 4-20mA signal if HART signal is present at terminals for DCS.
.
WARNING!
The boards may have deviations in the converted signal values by too high potential
difference between the negative supply terminal for powering the electronics and earth
ground, or by ground loops present in the installation.(See section 2.7.1and 2.7.2 below for
further details.)
Ensure that the grounding of the installation is appropriate for industrial applications. Follow
the rules for grounding as applicable in the place of installation.

2. INSTALLATION
2.1. STORAGE
In case of storage of instruments and accessories, proper care should be taken to protect them from any
possible damage. Always store instruments in their sealed original packaging until they are installed.
Provide adequate protection to prevent damages that may be caused by exposure to:
•Rain, excessive humidity and/or temperature excursions (inadequate sheltering).
•Dust (build-up of a corrosive patina that may cause oxidations and reduce isolation).
•Aggressive and polluting atmospheres with consequent corrosion.
•Access by insects/rodents (damage of packing or content).
•Mechanical shocks or unauthorized packing opening.
•Intense vibrations (loosening of fastened parts, fatigue failures, etc.).
•Any other possible risk.
Make sure the storage temperature does not exceed the limits of –20 to +70°C (-4 to 158°F) for
medium/long term storage (days/months) and -25 to +75°C (-13 to 167°F) for short term storage (a few
hours) during transportation or shipment.
2.2. UNPACKING AND INSPECTION
Upon receipt of the materials, you should check the integrity of the packing and the contents. In case of
damage due to shipping, you should promptly and properly report to the shipper, supplying all necessary
information.
If the instruments are not for immediate use, we recommend that you check that all characteristics shown
on the instrument’s label meet order specifications (model, supply voltage and frequency, input/output
range, certification, tag etc.) as well as the actual application requirements.
If not installed, equipment should be stored following the recommendations of the previous section.
2.3. ENVIRONMENTAL CONDITIONS
HIS products, like most modern electronic equipment, can operate in wide temperature and humidity
ranges. However, practical consideration suggests a guideline on operating environment for best results.
•Keep operating temperature below 35°C (95° F), ideally between 20°C and 25°C (68 and 77°F),
avoiding wide and rapid temperature excursions.
•Control relative humidity within 40 to 60% to avoid risks of static charges or condensation.
•Limit the presence of corrosive atmosphere, fumes and dust, sealing and purifying the control room
area and using air filters in the cabinet air intakes (clean cable entry path), if necessary.
•Reduce vibrations (if any) to safe levels.

PRODUCT INSTALLATION MANUAL DOCT-B3K4 PAGE 8OF 18
2.4. INTRINSIC SAFETY
The HIS system can interface HART devices located in Hazardous areas by interposition of suitable
galvanically isolated Intrinsically Safe Barriers. The barriers must allow bi-directional HART signal
communication in addition to the normal 4-20mA loop current processing.
2.5. MOUNTING
The MUX 2700 is a plug-in unit that must be inserted in the appropriate termination board position.
Exercise care in the insertion to mate the connector's pins, then firmly press the module to engage the
connector. Finally, engage the quick lock tabs on either side to secure the module to the termination board.
The HPTB is designed to be mounted on a T-type or G-type DIN rail.
2.6. CABLES
HART signals are brought to the MUX 2700 from the field via 5.08mm 3-tier screw terminal blocks
designated TB1. The MUX 2700 communicates to the DCS via the ELCO style connectors designated J1,
J2, J3 and J4. See Table 1 below for channel information.

PRODUCT INSTALLATION MANUAL DOCT-B3K4 PAGE 9OF 18
2.7. WIRING
The MUX 2700 is a plug-in unit and is connected to the HPTB by two 40 pin connectors. Therefore, all
electrical connections (supply, field connections, serial lines, etc.) are made at the termination board unit.
Refer to Figure 1 for a simplified representation of the termination board configuration and the overall
outside dimension of the product in inches.
Figure 1 –HPTB Configuration
HPTB/32/TR-AO-01

PRODUCT INSTALLATION MANUAL DOCT-B3K4 PAGE 10 OF 18
2.7.1. POWER
Connect 24 VDC to the 2-pin removable terminal at the end of the HPTB. The connector is polarized, so
you cannot insert it incorrectly. The polarity is marked on the terminals. A reverse polarity shunt diode and
series fuse protection are provided to avoid damaging the module in case of accidentally reversing the
polarity connection. In this case, the reverse voltage is clamped at –1.2 V and the fuse blows. Restore
correct supply polarity and replace the blown fuse. Be certain to reinstall a good, properly sized, new fuse.
WARNING!
Improper supply connections can seriously damage the instrument and result in risk of fire
or explosion in hazardous locations!
DC SUPPLY REQUIREMENTS: The MUX is nominally rated for 24 VDC but will function from
approximately 20-30 VDC. The MUX draws a maximum of 100mA from the supply. If the power LEDs fail
to light check that the polarity of the supply line is correct.
WARNING!
Note that a crude, poorly filtered or unregulated supply can produce destructive (hundreds
of volts) voltage spikes during supply transformer switch-off transient. This could cause
minor problems to electro-mechanical components like relays or solenoids but will surely
degrade or destroy electronic equipment.
2.7.2. GROUNDING
The HPTB provides an earth terminal lug for connecting the various shield wires to earth. Also included
with the HPTB is a DIN rail mountable terminal block. Use of the terminal lug and terminal block for earth
grounding will provide the shortest path and best practice for grounding of the HPTB. A 10-14 AWG cable
should be secured between the terminal lug and DIN rail block which provides a single point to properly
ground field wiring cable shields. This terminal may not be necessary to use if best practice grounding
techniques are employed.
The HPTB board provides connections of the shield pins T, H, w, and FF for J1 though a customer
selectable jumper to provide direct connection to the earth terminal lug, or to provide this connection
through capacitive coupling. Refer to Table 2.
The HPTB also provides customer selectable capacitive coupling for the shielding. Setting the shield to be
direct coupled or capacitively coupled is accomplished through jumper shunts. Placing the jumper shunt
across the pins will bypass the capacitor and direct couple the corresponding shield to earth. Refer to
Table 2 for a complete list of the shunts and the associated shield. For best practice any shield should be
direct coupled at one end of the circuit.
