General
The HART Loop Converter is an isolated barrier suitable for intrinsically safe applications.
The device supplies field devices and can be connected in parallel to existing HART circuits.
The device analyzes up to four HART variables (PV, SV, TV, QV). Three HART variables
can be transformed into varying current signals from these four HART variables. These
signals are used to display the values via the analog inputs of the process control system.
The device is easily configured by the use of keypad or with the PACTware configuration
software.

Danger!
Explosion hazard from damaged electronic components
Premature wear of electronic components in a device that was previously used in a
general electrical installation can cause sparks that can ignite the surrounding potentially
explosive atmosphere.
Never install devices that have already been operated in general electrical installations in
electrical installations used in combination with hazardous areas!
Danger!
Explosion hazard from pollution
An excessively polluted surface of the device can become conductive and consequently
ignite a surrounding potentially explosive atmosphere.
Ensure that you install the device only in environments with a pollution degree 2 or better
according to IEC/EN 60664–1.
3.1 DIN Mounting Rail
The devices are mounted on a 35 mm DIN mounting rail according to EN 60715.

Mounting and Installation
3.2 Power Rail
To reduce wiring and installation costs, Power Rail is the optimum solution. The Power Rail
is a DIN mounting rail with plastic insert, that delivers power to the devices (24 V DC) and
transfers bus signals and a collective error message.
The Power Rail is factory-equipped with cover and end caps. These parts cover empty and
open segments of the Power Rail. Thus, the Power Rail is protected from contamination.
Additionally the cover and end caps prevent that electrically conductive parts come in
contact with the Power Rail.
Power Rail UPR-03
The Power Rail UPR–03 has 3 conductors.
• 2 conductors for power
• 1 conductor for collective error messaging

3.4.3 Connecting a HART Handheld to the Field Device
You have two options for connecting a HART handheld to the field device:
• Connection to terminals 22/24 of the isolated barrier, see chapter 3.4.2
• Connection to the field cables from the isolated barrier to the field device
Danger!
Risk of explosion
Danger of explosion when using a non-certified HART handheld in a hazardous area.
Use a HART handheld certified for use in hazardous areas if the field cables lead into
a hazardous area.
Transmitting the HART signal using the current outputs of the isolated barrier is not possible.
3.4.4 Description of HART Operations
Dynamic Query of Variables
Universal HART command 3 is used to query dynamic variables from the field device.
This query is done either directly or by activating burst mode.
Burst Mode
Burst mode is the preferred method because this mode guarantees the fastest signal
transmission. The isolated barrier always tries to set the connected field device to
burst mode. See chapter 4.2.6.
The command for burst mode activation is sent to the field device under the following
conditions:
• after a restart or
• after resetting the isolated barrier after restarting the field device. In the process,
communication between the field device and isolated barrier must have been
reestablished again after a time-out.

Mounting and Installation
Polling Mode (Command and Answer)
The isolated barrier deactivates the burst configuration of the field device. The isolated
barrier performs the field device query using HART command 3. See chapter 4.2.6.
Procedure to Restore Burst Mode
If the isolated barrier does not receive any more data from the field device in burst mode, the
following actions are taken:
• The isolated barrier switches to polling mode.
• The isolated barrier checks whether another HART master has started in the query
signal circuit. If the isolated barrier has detected a HART master, the restoring of
burst mode is interrupted.
• If the isolated barrier does not detect any other HART masters, the isolated barrier
attempts to activate burst mode.
• As soon as the isolated barrier receives a burst message from the field device, the
isolated barrier switches from polling mode to burst mode.
This process enables other HART masters to deactivate burst mode momentarily for service
work.
Time-out (Communication Loss)
When the time-out time has been exceeded in the absence of communication, all outputs
switch to the defined safe state. Time-out can be adjusted.

Configuration
315702 2018-01
Note!
Note that the field device can be put into burst mode, in accordance to the isolated barrier
configuration. This also applies when a different HART master is in the HART circuit.
If a different HART master changes the burst configuration of the field device, the isolated
barrier waits until the other HART master logs out of the HART circuit. The isolated barrier
assumes that the other HART master is logged off when it does not send a message for
approximately 60 s. After this period of time, the isolated barrier activates the
burst configuration of the field device.
Defining ShortAddress
The defined short address is needed for identification of the field device during the
localization phase.
1. To enter a short address between 0 to 15, press the or buttons.
2. Confirm your entry with OK.
Selecting LocateMethod
According to the HART standard, more than one HART field device can be present in a
HART circuit. But the device can communicate only with a single HART field device.
This HART field device is identified during the localization phase.
1. Select the localization method with the or buttons.
2. Select fixed.
The device communicates with the field device that has a short address defined
under ShortAddress.
3. Choose search.
During booting, the device searches for the field device with the smallest short
address, beginning with the short address defined under ShortAdress. The address of
the field device found is stored by the device under ShortAddress. This accelerates
the device starting when it boots again.

Danger!
Explosion hazard from live wiring of non-intrinsically safe circuits
If you connect or disconnect energized non-intrinsically safe circuits in a potentially
explosive atmosphere, sparks can ignite the surrounding atmosphere.
Only connect or disconnect energized non-intrinsically safe circuits in the absence of a
potentially explosive atmosphere.
Danger!
Explosion hazard from sparking when using operating elements
Using operating elements in a potentially explosive atmosphere can cause sparks that can
ignite the surrounding atmosphere.
Only use operating elements (e.g., switch, slider, button, etc.) in the absence of a
potentially explosive atmosphere.

Operation
Display Indicators
In normal operation, the display shows:
• the current values of the HART variables PV, SV, TV, QV in the selected unit
• the present current output values for the three current outputs in mA
•the current device status
This display shows information about the device status of the field device (1 byte) and
about the response code (1 byte) of the field device. These two bytes are displayed in
the first line of the display in hexadecimal form with the code RC on the left side.
• the current setting of the type of communication
•LOOP Locate
The isolated barrier reestablishes the HART circuit. The isolated barrier
performs the field device query using the HART command 3.
• LOOP Poll
The isolated barrier performs the field device quer y using the HART command 3.
•LOOP Burst
The isolated barrier receives the HART command 3 of the field device.
• LOOP Mixed
The isolated barrier performs the field device query using the HART command 3
(polling). The field device is in burst mode, however it references a different
HART command than 3.
In the event of a fault, the display shows:
•Err Device Fault
Displays a device fault in the isolated barrier – red LED lights up.
• Err Communication
Displays a communication fault – red LED flashes.
• Err Field Device Malfunction
Displays a field device failure – red LED flashes.

Operation
Display Options for Current Output Values and HART Variables
• To select the displayed measured values or current output values, use the
and buttons.
• To select units for measured values, use the Unit menu. See chapter 4.2.5.
• Every time the isolated barrier receives a HART command 3 message from the
field device, the display is updated.
• The isolated barrier displays the current output values as a four-digit number. The
decimal point is set to provide the best possible resolution.
• The isolated barrier shows the floating point value for HART variables as follows:
• If possible, as a four-digit number with decimal point and without exponent.
Negative values are shown on the device with three digits because of the minus
sign.
• A digit is rounded as necessary. For example, the number 0.3456 is shown as
0.346.
• If the isolated barrier cannot show the floating point value, the mantissa and
exponent are shown in alternation.
5.2 Fault Message
The following table shows which fault message the current outputs send to the controller,
based on the characteristic.
