2 Overview
2.1 Range of application
The K-System devices from Pepperl+Fuchs are used for transmitting signals between the field devices
and the 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. 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.
This symbol warns of possible danger.
Failure to heed this warning may result in personal injury or death, or property
damage, including destruction.
This symbol warns the user of a possible failure.
Failure to heed this warning can lead to total failure of the equipment and any
other connected equipment.

The KF**-GUT-(Ex)1.D of the K system
(abbreviation: GUT) have been designed for
temperature measurement applications.
In this context, a GUT converts the signal of an
RTD, a thermocoupler, a potentiometer or a
voltage source to a proportional output current
which may, for example, be transmitted to a display
unit or to an analog input of the process control
system/control unit.
Two different, freely parameteriseable trip values of the input signal can be monitored via the two GUT
relay outputs.
It is also possible to process the modification of this signal per time unitinstead of the input signal.
2.2 Variants
The following variants of the RTD are available:
Ex = for the connection of field devices from the potentially
explosive area
without identifying letter = for the connection of field devices in the
safe area
D2 = with power pack for 24 V DC (green cover on the output
side); as for the power supply via Power Rail with combined failure
reporting please also refer to the "DIN-Rail Housing" catalog of
Pepperl+Fuchs or to the "CD-ROM catalog".
U8 = with omni-voltage power pack, which allows for power supply
with 20 V DC ... 90 V DC and 48 V AC ... 253 V AC without
switching and without considering the polarity (gray cover on the
output side)

3 Safety instructions
The KF**-GUT-(Ex)1.D temperature converter may only be operated by trained
professionals in a manner corresponding to this operation manual.
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 systems connected to them in question.
The devices may only be installed, connected, and adjusted by electrical
professionals outside the explosion-hazardous area.
If malfunctions 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.

5 Use in safety applications (SIL)
5.1 Premises
The base for use of equipment for safety applications is the SIL report P+F 05/03-24 R023. This report
is available at www.pepperl-fuchs.com.
The SIL report is based on certain assumed premises. On the part of the user, the premises listed
below must be provided.
Repair time
While preparing the SIL report, it was assumed that, after occurrence of a visible fault (e. g. a relay de-
energised), it would be repaired within 8 hours (e. g. by repairing a sensor burnout).
Testing time
One assumption in the calculations in the SIL report was that notification of a dangerous fault (e. g.
output current outside the range of 4 mA ... 20mA) would be detected by the control system within an
hour.
Low Demand Mode
The operation mode according to IEC 61508 assumed for the SIL report is the Low Demand Mode (for
a definition, see IEC 61508, part 4, section 3)
Power supply
Failure of the external power supply was not taken into consideration and must be handled additionally
when evaluating the overall safety function.

Pepperl+Fuchs Group • Tel.: Germany [phone] • USA [phone] • Singapore [phone] • Internet http://www.pepperl-fuchs.com
Temperature conditions and testing times
The PFD values (PFD = Probability of Failure on Demand) of KF**-GUT-(Ex)1.D equipment lie within
the range specified for SIL2 for the testing times given in the report. The PFD values were calculated
based on the assumption of a mean ambient temperature of 40 °C. At a temperature of 60 °C the
failure rate must be multiplied by a factor of 2.5. In practice, this means a correspondingly reduced
testing interval. For mean temperatures between 40 °C ... 60 °C the factor can be adjusted linearly.
The test interval can be extended by connecting the two relay outputs. Here, the parameters for both
relay outputs must be set to the same values. For details, see the SIL report.
Basically, for safe opening you should connect two NC contacts in series, and for safe closing connect
two NO contacts in parallel.
5.2 Safe output states
Relay outputs
In the safe state, the relay is deactivated, that is, the working contact is open.
Current output
The safe state here is the indication of an error state via output of the signal level specified for this in
NE43.
5.3 Configuration
The configuration of the device must be performed exclusively using the control panel. Configuration
through the device interface is not permitted for safety-relevant applications.
The functions set must be checked using suitable testing after configuration is complete.
Example 1: The power output is configured with a start value of 50 °C and a final value of 500 °C at
4 mA ... 20 mA (NE43) output characteristic, and the input is configured for a Pt100 type sensor.
By applying the corresponding input values (RTD simulator, decade resistor), it can be tested whether
the output current at 50 °C is 4 mA and at 500 °C is 20 mA. The output current can be measured using,
e. g., a measurement device (DMM).

Example 2:
The input is configured for a type K thermocouple. The parameterisation of the relay output is:
switching point of relay 1 at 1000 °C, high-temperature alarm (MAX) and mode of operation passive.
If input signals corresponding to, e. g., 500 °C and 1001 °C are applied, the switching of the relay can
be tested by measuring the contact resistance.
After configuration, the settings must be protected from accidental changes by activating password
protection.
5.4 Regular testing of function
The function of the device must be tested at the test intervals (T[proof]) specified in the SIL report. Tests
as described in section 5.3 are suitable for this purpose.
5.5 Evaluation of the device outputs using subordinate control systems
As a premise for evaluation of equipment for safety functions, the settings of the power output
characteristic must be set to 4 mA ... 20 mA (NE43).
The system which evaluates error states must correspondingly be configured to use NE43
specifications regarding the signal level.
5.6 Features not suitable for safety-relevant applications
Configuration software
The configuration software is not part of the considerations for evaluation of safety functions of the
device and may thus not be used to configure safety-relevant functions.
User-defined characteristic
The user-defined characteristic consists of a linearisation table created in the configuration software
(PACTware™), which must be loaded into the configuration software of the device.
Since the device may not be configured using the configuration software (see section 5.3), the "user-
defined characteristic" feature may not be used for safety-relevant applications.

Maintain in case of error
The function "Maintain in case of error" could lead to a failure to signal fault states through the outputs,
so that they are not detected. It is also possible that the specified safe state would not be entered.
Trend function
The trend function is used for estimation of future behaviour of a value. The trend is measured
periodically and represented as a linear increase between the two measurement points. This
approximate representation is only suitable for certain applications and is therefore not considered for
the safety technology evaluation.
Simulation current and relay simulation
The simulation mode of the device is an aid for commissioning which simulates the presence of a
certain output signal which can then be evaluated by a general control layer.
In this mode, the outputs are independent of the input values, thus there is no signal transfer between
sensors connected and the outputs.
Thus the device is not in a normal operating state. For this feature, therefore, no safety evaluations
have been performed and as a result, it may not be used for a safety-related application.
5.7 Firmware versions in combination with the safety function
One factor in the consideration of use of the KF**-GUT-(Ex)1.D for safety functions is the operational
reliability of the devices.
This was determined for the supplied firmware at version 1.09 or better. Thus the safety evaluation is
valid for versions 1.09, 1.14, 1.38, 1.42.

6.2 Connection
The removable terminals of the KF series simplify considerably
the connection and the switch cabinet installation. They allow a
quick and fault-free replacement of devices in case of a service
event.
Terminals are equipped with screws, are self-opening, have a
large connection area for a wire cross-section of up to 2.5 mm²
and coded plugs, making it impossible to mix them up.
The intrinsically safe field circuit is connected to the blue terminals
1 ... 6 of KF**-GUT-(Ex)1.D and may be guided into the potentially
explosive area using connector cables in accordance with
DIN EN 60079-14.
The non-intrinsically safe field circuit is connected to the green
terminals 1 ... 6 of KF**-GUT-(Ex)1.D.
Terminal 5 remains always free on the GUT.

7 Display mode and error signals
The current measurement value is displayed in the selected unit in the normal mode. As for the
selection of the unit, see section 8.3.
If a fault occurs which can be detected by the GUT, one of the following messages is displayed until
the fault is cleared:
•Err INT in case of an internal GUT error; please contact
Pepperl+Fuchs
•Err MEM in case of an error in the GUT memory; please contact
Pepperl+Fuchs
•Err SB in case of a sensor breakage (only for the sensor types RTD and TC);
if the redundant thermocouple function has been selected (see section 8.2.3), a
sensor breakage may also trigger the message Err DV RED (see below)
•Err SC in case of a sensor short-circuit (only for RTD sensor type)
•Err CJC if the internal cold junction compensation has been selected (see section 8.2.3) and
a breakage or short circuit has occurred within the K-CJC terminal
•Err SB RED if the redundant thermocouple function has been selected (see section 8.2.3) and a
sensor breakage has occurred in the second thermocouple
•Err RED if the redundant thermocouple function has been selected (see section 8.2.3) and a
sensor breakage has occurred for both thermocouples
•Err DV RED (for "deviation from redundant TC"), if the redundant thermocouple function has been
selected, two thermocouples are connected and the tolerated deviation is exceeded
between the two couples is exceeded (see section 8.2.3 and section 8.2.4)
Be aware that the error signals Err SB, Err SC, Err SB RED and Err RED refer to the sensor function
and not to the sensor lines.
In case of a fault, the relays normally switch to the idle state. Exceptions are described in section 8.2.4
and section 8.5.1 (Maintain in case of error).
The behaviour of the current output in case of a fault is described in section 8.2.4 and section 8.6.2.

8.1 Parameterisation mode control panel
8.1.1 Invocation
A change in device data will change the operation of the device!
Before entering new data into the device, you should therefore ascertain that no danger
to the installation will result.
This manual describes parameterisation mode of the GUT using the control panel.
Parameterisation mode for the GUT is more convenient with a PC.
A connection cable and a CD with the PACTwareTM configuration software along with its
user manual can be ordered as a programmer's kit from Pepperl+Fuchs.
PACTwareTM and the manual can also be obtained on the Internet.
Some specialised functions can only be selected using PACTwareTM, for instance, pulse
suppression as an alternative to the start-up override.

By pressing the ESC key (perhaps several times), you can return to the display mode from every menu
item of the parameterisation mode. If 10 minutes elapse without a key being pressed in
parameterisation mode, the device switches automatically back to display mode.
8.1.2 Password
You can use a password to protect the parameterisation from unauthorised modifications (see
section 8.7; inactive in the GUT default setting).
If the password protection is active, the various settings performed in the parameterisation mode may
be viewed before the password entry; however, modifications are not possible in this way. The first
time an attempt is made to modify a setting, the device automatically displays a window for entering
the password.
After each transition from the display mode to the parameterisation mode, the password must be
entered once.
The password cannot be modified and is 1234.
To enter the password:
*The value changes stepwise when actuating the !or "key. When you hold down the !or "key,
the setting "scrolls" to higher or lower values.
