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.

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.

6 Display modes and error messages
The following appear on the display in normal mode:
• the current values for HART variables PV, SV, TV, QV in the selected unit and
• the actual current output values Ch1, Ch2, Ch3 in mA.
• Please use the S and T keys to select the displayed measured value
or current output value.
• To select the units for the measured values see section 8.2.
• The display is updated every time the HLC receives a HART command 3 message from the field
device.
• Current output values are displayed as a four-digit number. The decimal point is set to give the best
possible resolution.
• The floating decimal values for the HART variables are displayed as follows:
− if possible as a four-digit number with decimal point and without an exponent (negative values
have three digits because of minus sign)
− a number may be rounded up (0.3456 appears as 0.346)
− if this display is not possible, the mantissa and exponent are displayed alternately.
If the restart inhibit (see section 8.5.5 and 8.5.7) is triggered but the device continues operating
normally, a corresponding message appears in the second line of the display.
If a fault occurs, one of the following messages is displayed until the fault is rectified:
• Err device fault (red LED lights up)
• Err communication error (red LED flashes)
• Err sensor fault (red LED flashes)
If switching the HLC on/off and checking the cables does not rectify the fault, please contact
Pepperl+Fuchs or the field device manufacturer.
The relays power down when a fault occurs.
For information on the behaviour of the current output in the event of a fault, see section 8.4.4.

Description of HART operations:
7 Description of HART operations
Dynamic variable acquisition
HART command 3 is always used to obtain the applicable dynamic variables, either directly or by
activating it in the Burst Mode.
Burst Mode operation
The HART Burst Mode is the HLC preferred one because it ensures a faster operation. The HLC will
therefore always try to set the connected device in the Burst Mode. The Burst Mode activation
command will be sent to the field device in the following situations:
• after an HLC unit power-up (or after an internally generated reset)
• after a field device power-up
• when the communication with the field device is recovered after a time-out.
"Command and answer" operation
If the field device doesn't support the Burst Mode, the HLC will use the normal "command and answer"
mode.
Burst mode recovery procedure
If the HLC stop receiving the burst frames, the following recovery procedure will be applied:
• The HLC immediately goes into the "command and answer" mode.
• The HLC then check if another HART master is sending messages on the loop; if another master
is found, the HLC will not try to re-enable the Burst Mode.
• If no other HART master is found the HLC will keep trying to re-enable the Burst Mode.
• As soon as any Burst frame is again received, the HLC immediately return to the Burst Mode.
This procedure makes possible for another HART master to temporary disable the Burst Mode, as
could be required for servicing reasons.
"Communication-loss" time-out

If available, the HLC activates Burst Mode for the HART field device to achieve maximum
communication speed. The HLC uses the universal HART command 3 to retrieve variables (PV, SV,
TV, QV, if available).
8.3.1 Mode
Depending on the setting, the HLC operates as a primary or secondary HART master device according
to HART standards and is fully compatible with each HART handheld terminal and any other HART
master devices.
8.3.2 TimeOut
If the HLC does not receive a valid HART message after the preset time, the fault indication
Communication fault is issued. Time-out range is 5 s to 60 s in increments of 5 seconds.
8.3.3 ShortAddress and LocateMethod
More than one HART field device may be present in a HART loop, as specified in the HART standards.
However, the HLC can only communicate with one HART field device at a time. This field device is
identified during the localization phase.
• If you select LocateMethod fixed, the HLC communicates with the field device that was assigned a
short address under ShortAddress.
• If you select LocateMethod, the HLC runs a search for the shortest address – beginning with the
address assigned under ShortAddress – and then communicates with this device. The device
address is saved to accelerate the next start-up process under ShortAddress.
8.3.4 Rebuild
If the connection to the HART field device is lost, you can use Rebuild to run through the localization
phase without having to switch the HLC off and on again.
Pressing the OK key when On Rebuild is flashing prompts the HLC to start searching for connected
HART devices (see section 8.3.3) in the same way as during start-up.

8.4.1 Assignment
The values of the HART variable selected here (PV, SV, TV, QV) are displayed at the current output
(see section 8.4.2). The number of available variables depends on the HART field device.
If disabled is selected, the downscale error current is issued constantly at the current output (0 mA or
2 mA depending on the characteristic, see section 8.4.4).
8.4.2 Characteristic
The Start value and End value parameters (see section 8.4.3) allow you to define a value range for
the assigned HART variable, which is used as a measurement range in the application. This
measurements range is represented at the output signal in linear form (start value to 4 mA, end value
to 20 mA, proportional intermediate values).
• In the characteristic 4 - 20 unlimited, you can evaluate measurement range shortfalls up to 0 mA
and excess measurement ranges up to approx. 23 mA.
• In the characteristic 4 - 20 NE43, you can evaluate measurement range shortf alls up to 3.8 mA and
excess measurement ranges up to 20.5 mA.
• Measurement ranges that exceed the specified linear range cannot be evaluated. If the range is
exceeded, the minimum and maximum stated values are issued continually.

8.5.5 Restart inhibit
With the restart inhibit, you prevent momentary trip violations from going unnoticed by
operating personnel.
If Restart inhibit on is selected, after the relay switches, the new status remains active until the ESC
key is pressed or the device is restarted. This will rese t the relay unless the trip violation is still pending.
8.5.6 Response delay
Setting a response delay > 0 seconds prevents momentary trip violations from triggering an alarm.
• The relay only switches when the trip value exceeds or falls below the trip point for a period longer
than the delay time without interruptions.
• The relay only switches back when the trip value exceeds or falls below the trip point/hysteresis for
a period longer than the delay time without interruptions.
• Momentary excesses/shortfalls have no effect.
