• HART Loop Converter KFD2-HLC-Ex1.D.2W
• HART Loop Converter KFD2-HLC-Ex1.D.4S
2.2 Function
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.
KFD2-HLC-Ex1.D.2W
In addition to the current outputs, the device has two changeover contacts. These
changeover contacts can be programmed so that the changeover contacts function as
limit values for the HART variables.
KFD2-HLC-Ex1.D.4S
In addition to the current outputs, the device has four NO contacts. These NO contacts can
be programmed so that the NO contacts function as limit values for the HART variables.

3 Mounting and Installation
3.1 DIN Mounting Rail
The devices are mounted on a 35 mm DIN mounting rail according to EN 60715.
Figure 3.1 Example: DIN mounting rail UPR-MR (35 mm x 15 mm)
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.

3.2 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

3.3 Mounting
Mounting in the Non-Hazardous Area
Mounting the Device
Snap the device onto the DIN mounting rail in a vertical downward movement. 
See figure below.
Mounting in Areas that Require the Equipment Protection Level Gc
Danger!
Danger to life from electric shock
Absent or insufficient insulation can result in electric shock.
Only connect supplies that provide protection against electric shock to power feed
modules (e. g. SELV or PELV).
Caution!
Property damage from use of isolators for Power Rail supply
Using the isolators for Power Rail supply can damage the isolators and make the
Power Rail fail.
Do not supply the Power Rail via isolators.
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.

Mounting the Device
Snap the device onto the DIN mounting rail in a vertical downward movement. See figure
below.
Danger!
Explosion hazard from wrong mounting
The device safety can be impaired by external environmental influences and by
mechanical stress. This can lead to sparking that can ignite a surrounding potentially
explosive atmosphere.
Mount the device in a surrounding enclosure that complies with IEC/EN 60079–0and that 
is rated with the degree of protection IP54 according to IEC/EN 60529.
CORRECT: Device snapped on vertically. INCORRECT: Device snapped on from the side.
Can damage the contacts and cause the device to fail.

3.4 Connection
Danger!
Danger to life from incorrect installation
Incorrect installation of cables and connection lines can compromise the function 
and the electrical safety of the device.
• Observe the permissible core cross section of the conductor.
• When using stranded conductors, crimp wire end ferrules on the conductor ends.
• Use only one conductor per terminal.
• When installing the conductors the insulation must reach up to the terminal.
• Observe the tightening torque of the terminal screws.
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 wrong separation distances
If you do not observe the minimum separation distances between intrinsically safe circuits
of associated apparatus and non-intrinsically safe circuits, this can lead to added currents
or voltages. This can result in a current/voltage flashover generating sparks. The sparks
can ignite the surrounding potentially explosive atmosphere.
Ensure that you observe the compliance of the separation distances to all non–intrinsically
safe circuits according to IEC/EN 60079–14.
Danger!
Danger to life from electric shock
Absent or insufficient insulation can result in electric shock.
• Maintain sufficient distance between the connection lines, terminals, housing, and the
environment.
• Insulate connection lines, terminals, and the housing from the environment.
Danger!
Danger to life from electric shock
Absent or insufficient insulation can result in electric shock.
Only connect supplies that provide protection against electric shock (e. g. SELV or PELV).

The removable terminal blocks simplify connection and control cabinet construction
significantly. These terminal blocks offer adequate space for the connection of leads with
core cross-sections of up to 2.5 mm2(14 AWG). The terminal blocks are coded with red
coding pins so misconnection of terminal blocks are eliminated.
Connecting Circuits
1. Connect the field circuit.
2. Connect the control circuit.
Danger!
Danger to life from electric shock
Working on live parts at voltages higher than 50 V AC or 120 V DC can result in electric
shock.
1. De-energize the device.
2. Secure the circuit against reconnection.
3. Verify that the device is de-energized at all poles.
4. Provide protection from adjacent live parts, if present.

3.4.1 Input Connection (Field Circuit)
Connecting the Field Circuit
1. Connect the field circuit to the blue terminals.
2. Observe the tightening torque of the terminal screws. The tightening torque is
0.5 Nm to 0.6 Nm.
The intrinsically safe field circuit may be routed in the hazardous area with connection lines
in accordance with DIN EN 60079-14. You can connect the following field devices:
1. any separately supplied HART current circuit with transmitter or positioner connected in
parallel
Connection to terminals 2 and 3
2. a HART-capable active current source, e. g., a separately supplied HART measuring
transmitter
Connection to terminals 2 and 3 with bridge between terminals 5 and 6
3. a 2-wire HART measuring transmitter, e. g., HART measuring transmitter with an analog
output signal of 4 mA to 20 mA
The HART measuring transmitter is supplied by the isolated barrier
Connection to terminals 1 and 3 with bridge between terminals 4 and 5
Danger!
Explosion hazard from wrong separation distances
If you do not observe the minimum separation distance between 2 intrinsically safe circuits,
this can lead to added currents or voltages. This can result in a current/voltage flashover
generating sparks. The sparks can ignite the surrounding potentially explosive
atmosphere.
Ensure that you observe all separation distances between 2 adjacent intrinsically safe
circuits according to IEC/EN 60079-14.
