2Overview

2.1 Application

The devices of the K-System from Pepperl+Fuchs are used to transmit signals between field devices

and the process control system or control.

Devices with the "Ex" code in their type identifiers are suitable for connection to field devices in the

hazardous area. The field current circuits of these devices are intrinsically safe and are galvanically

isolated from the not intrinsically safe circuits. The devices thus represent an electrical isolation

between the hazardous area and the safe area within a system.

Devices without an "Ex" code can be used for signal transmission between field devices in the safe area

and the process control system or the control.

This symbol indicates a warning about a possible danger.

Failure to observe this warning may result in personal injury or death, or property

damage or destruction.

This symbol warns of a possible fault.

If the instruction given in this warning is not heeded, the device and any systems or

plants connected to it could develop a fault or even fail completely.

This symbol brings important information to your attention.

Temperature Trip Amplifier KFD2-GU-(Ex)1

Overview

The temperature trip amplifier KFD2-GU-(Ex)1 of the

K-system are used for temperature measurement.

Further information (e. g. certificates, the data sheets

for the device and the manual for the K-system) can

be found on our Internet page www.pepperl-

fuchs.com/pa (under product search, enter *GU*).

• You can connect resistance temperature sensors or thermocouples to

the input of the device (types: B, E, J, K, L, N, R, S, T). The device can also process a unit current

signal or a unit voltage signal.

• Two different limit values of the input signal can be monitored with the aid of the two relay outputs

on the device and parameters can be set freely for them.

• You can connect a PC for programming and diagnostics with PACTware™(see section 6 and

section 7) on the device.

2.2 Versions

The following versions of the device are available:

• KFD2-GU-1, device with a power supply 24 V DC for connection of field devices in the safe area

• KFD2-GU-Ex1, device with a power supply 24 V DC for connection of field devices in areas exposed

to danger of explosion

Safety Instructions

3 Safety Instructions

The device may only be operated by trained personnel in a manner corresponding to

this manual.

Protection of operating personnel and the plant is only guaranteed if the device is used

according to their specifications. Any use other than that described in the manual

endangers the safety and functionality of the device and the connected systems.

The device may only be mounted, connected and adjusted by electrical professionals

outside the explosion hazardous area.

If malfunctions cannot be eliminated, places the device out of service and protect them

from accidental use. The device may only be repaired directly by the manufacturer

Pepperl+Fuchs. Any opening or change in the device is dangerous and are therefore

not to be performed. They void any warranty.

Responsibility for adhering to local safety regulations and directives is held by the

operator.

Explosion Protection

4 Explosion Protection

For primary explosion protection, that is, measures to avoid or restrict the

production of a dangerous, explosive atmosphere, please consult the

ATEX directive or the corresponding national provisions.

For secondary explosion protection, that is, measures to avoid the

ignition of a surrounding explosive atmosphere by electrical equipment,

Pepperl+Fuchs will gladly provide you with a copy of the "Ex-protection

manual" for a nominal fee.

Please pay particular attention to EN 60079-0, EN 60079-11, and

EN 60079-15 or the corresponding national provisions.

Pepperl+Fuchs also provides a seminar on the topic of explosion

protection.

5 Mounting and Connection

5.1 Mounting

The devices of the K-System from Pepperl+Fuchs can be mounted on a

35 mm top-hat rail corresponding to EN 60715. The devices must be snapped

onto the rail vertically, and never slanted or tipped to the side.

Further mounting alternatives, e. g. using the Power Rail, can be found in the

operating instructions for the K-System on our internet page

www.pepperl-fuchs.com/pa (under product search, enter *GU*).

The temperature trip amplifier KFD2-GU-(Ex)1 are constructed in protection classIP20

and must therefore be protected from undesirable environmental conditions (water,

dust, small foreign objects).

5.2 Connection

The KF series' slip-off terminals significantly simplify connection

and construction of switching cabinets. They allow quick and

error-free exchange of the unit when service is needed.

The terminals can be screwed on, are self-opening, and have

generous connection room for a wire diameter of up to 2.5 mm²

and coded plugs, so that leads cannot be confused.

284503 2015-09

Temperature Trip Amplifier KFD2-GU-(Ex)1

Mounting and Connection

The intrinsically safe field circuit is connected to the blue

terminals 1 to 6 of the KFD2-GU-Ex1. The circuit can be

directed with interface cable based on EN 60079-14 into

the area subject to the danger of explosion.

The non-intrinsically safe field circuit is connected to the

green terminals 1 to 6 of the KFD2-GU-1.

In both cases you can connect:

• a resistance temperature sensor Pt100 or Ni100

in 2-wire design (terminals 2 and 3)

in 3-wire design (terminals 1 to 3)

in 4-wire design (terminals 1 to 4)

• a thermocouple of type B, E, J, K, L, N, R, S, or T

(terminals 1 and 2). For an internal cold junction

compensation, you will need terminal K-CJC as an

accessory instead of the normal terminal 1 to 3.

• a source for a unit current signal of 0 mA ... 20 mA or 4

mA ... 20 mA (terminals 2 and 5)

• a source for a unit voltage signal 0 V ... 10 V (terminals

2 and 6)

The function of the green terminals 7 to 15 is as follows:

• terminals 7 to 9: relay 1

• terminals 10 to 12: relay 2

• terminals 14(+)/15(-): 24 V DC power supply (13 free)

For power supply via Power Rail, please refer to the

"Interface Technology" catalog of Pepperl+Fuchs.

For a detailed account of the terminal assignments,

please refer to the data sheet.
