This symbol warns of possible danger.
Failure to heed this warning may result in personal injury or death, or property damage,
including destruction.

Warning

This symbol warns the user of a possible fault.
Failure to heed this warning can lead to total failure of the device and any other
connected equipment.

Attention

Note

This symbol draws attention to important information.

2 Overview

2.1 Range of application

The K-System devices from Pepperl+Fuchs are used for transmitting signals between field devices
and a process control system/control system.

The devices marked with "Ex" in the type designation are suitable for the connection of field devices
used in potentially explosive atmospheres. Safe field circuits for these devices are intrinsically safe
and are galvanically isolated from non-intrinsically safe circuits. The devices thus establish an
electromagnetic separation between the potentially explosive atmospheres and the safe areas in a
system.

Devices without Ex-identification can be used to transmit signals between field devices and the
process control system/control unit.

HART Loop Converter KFD2-HLC-(Ex)1.D(.**)

Overview

The HART system allows digital communication with HART field devices via cables for analogue
4 mA ... 20 mA field circuits.

HART

More information (for example, certificates and data sheets for the HLC and the operating manual for
the K-System) can be found on our webpage www.pepperl-fuchs.com (enter *HLC* in the product
search).

The HART Loop Converter
KFD2-HLC-(Ex)1.D(.**) from the K-System
(HLC) evaluates up to four HART variables
(PV, SV, TV, QV). The information can be
converted to three different 4 mA ... 20-mA
current signals and conveyed to display
devices or analogue inputs on the process
control system/control system, for example.

In addition, two or four configurable trip values
from the HART variables can be monitored via
the relay outputs on the KFD2-HLC­(Ex)1.D.2W or KFD2-HLC-(Ex)1.D.4S.

Safety instructions

3 Safety instructions

The HART Loop Converter KFD2-HLC-(Ex)1.D(.**) may only be operated by trained
professionals in a manner corresponding to this operating manual.

Warning

The protection of operating personnel and of the system is only ensured if the devices
are used in accordance with their intended purpose. Any other type of operation than
that described in this manual places the safety and functionality of the devices and

Warning

systems connected to them in question.

The devices may only be installed, connected, and adjusted by electrical professionals

outside the hazardous area.

If faults cannot be eliminated, the devices must be taken out of operation and protected
from being placed in service again inadvertently. Devices must only be repaired directly
by the manufacturer Pepperl+Fuchs. Tampering with or making changes to the devices
is dangerous and therefore not permitted. They render the warranty void.

The responsibility for the adherence to local safety standards lies with the operator.

Explosion protection

4 Explosion protection

For primary explosion protection, that is, for measures to be taken to
prevent or hinder the development of a dangerous explosive
atmosphere, please observe the guideline 1999/92/EC (ATEX 137) or
the corresponding national guidelines.

For secondary explosion protection, that is, for measures to hinder the
ignition of a surrounding explosive atmosphere by electrical devices,
Pepperl+Fuchs will gladly make the "Explosion Protection Manual"
available to you for a nominal fee.

Note in particular DIN EN 60079-10, DIN EN 60079-14, DIN EN 50014
and DIN EN 50020, or the corresponding national guidelines.

Pepperl+Fuchs also offers a seminar on the topic of explosion
protection.

5 Installation and connection

5.1 Installation

The HART Loop Converter KFD2-HLC-(Ex)1.D(.**) is constructed in protection degree
IP20 and must therefore be protected from undesirable ambient conditions (water,
small foreign objects).

Attention

The devices of the K-system from Pepperl+Fuchs and thus also the
HART Loop Converter KFD2-HLC-(Ex)1.D(.**) can be mounted on a 35 mm
standard rail corresponding to DIN EN 50022. The devices must be snapped
onto the rail vertically, and never slanted or tipped to the side.

Additional possibilities for mounting, e. g. using the Power Rail, can be found
in the K-System operating manual on our webpage www.pepperl-fuchs.com

5.2 Connection

The detachable terminals of the KF-ser ies considerably simplify
the connection and the switch cabinet assembly. They make it
possible to replace devices quickly and without error if a
customer service becomes necessary.

Terminals are equipped with screws, are self-opening, have a
large connection area for a wire cross-section up to 2.5 mm²
and coded plugs, making it impossible to mix them up.

Installation and connection

5.2.1 Connection input (field circuit)

The intrinsically safe field circuit is connected to the blue terminals 1 to 6 on the KFD2-HLC-Ex1.D(.**).
This may be conducted using DIN EN 60079-14-compliant leads into the hazardous area.

You can connect the following three operating modes:

1. any separately powered HART loop with a transmitter or positioner in a parallel circuit (as with
HART handheld terminals, terminals 2 and 3)

2. an active HART-compatible mA source, e. g. a separately powered HART transmitter (terminals 2
and 3, bridge between terminals 5 and 6)

3. a 2-wire HART transmitter (HART transmitter with analogue 4 mA ... 20 mA output signal) powered
by the HLC (terminals 1 and 3, bridge between terminals 4 and 5)

Installation and connection

5.3 Setting parameters of HART field device

In order to set the parameters of the connected HART field device, you will require a HART handheld
terminal which you can connect to terminals 22/24 or the field cables. Transmitting the HART signal
via the current outputs of the HLC is not possible.

When connecting the field cables, use an old handheld terminal if the field cables lead
through a hazardous area.

Warning

5.4 Front

The following are located on the front of the HLC:

• a display for showing the measured values, the current output values
and fault messages and for displaying in parameterization mode

• four keys for selecting the displayed values/current output value and for
setting the parameters of the HLC:

S (Up) T (Down) ESC (Escape) OK

• RS 232 serial interface for a connection to a PC for setting parameters
and diagnosis of the HLC using PACT ware

TM

(available from 2009)

• LED ERR (red) to indicate a fault

• LED PWR (green) to indicate the presence of the supply voltage

also for KFD2-HLC-(Ex)1.D.2W and KFD2-HLC-(Ex)1.D.4S:
