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.
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 fault.
Failure to heed this warning can lead to total failure of the device and any other
connected equipment.
This symbol draws attention to important information.

Overspeed/Underspeed Monitor KF**-DWB-(Ex)1.D
Overview
4
Typical applications for the Overspeed/Underspeed
Monitors KF**-DWB-(Ex)1.D of the K-System
(abbreviated DWB) are limit-value monitoring during
flow and rotational-speed measurements (Max alarm
and Min alarm).
The Overspeed/Underspeed Monitors are
parameterized using an integrated control panel.
More information (for example, certificates and data
sheets for the DWB and the operating manual for the
K-System) can be found on our webpage
www.pepperl-fuchs.com (enter *DWB* in the product
search).
2.2 Model variants
The following variants of the Overspeed/Underspeed Monitor are available:
.D = with keypad
Ex = for connection of field devices in areas exposed to danger of
explosion
without identifier letters = for connection of field devices in the
safety area
D2 = with a power supply of 24 V DC
A5 = with a power supply of 115 V AC
A6 = with a power supply of 230 V AC

Overspeed/Underspeed Monitor KF**-DWB-(Ex)1.D
Overview
2.3 Inputs and outputs
A K-System DWB from Pepperl+Fuchs has
• an input for connecting a field device.
−With KF**-DWB-Ex1.D, this input is intrinsically safe
(blue terminal block). You may connect either a
NAMUR sensor or a mechanical contact.
−With KF**-DWB-1.D, the input is not intrinsically safe
(green terminal block). You may connect a NAMUR
sensor, a mechanical contact or a 3-conductor
sensor. A DWB also has
•tworelay outputs for limit-value display. These are for
−Max alarm and for
−Min alarm and
• a non-intrinsically safe input for the
−remote activation of the start-up override and the
−resetting of the restart inhibition (alarm freeze).

3 Safety Notes
The Overspeed/Underspeed Monitor KF**-DWB-(Ex)1.D must only be operated by
trained personnel in accordance with this handbook.
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 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 free.
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 devices of the K-system from Pepperl+Fuchs and thus also the
Overspeed/Underspeed Monitor KF**-DWB-(Ex)1.D can be mounted on a
35 mm standard rail corresponding to DIN EN 60175. 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 data sheets and in the K-System operating manual on our webpage
www.pepperl-fuchs.com (enter *DWB* in the product search).
The Overspeed/Underspeed Monitor KF**-DWB-(Ex)1.D is constructed in protection
degree IP20 and must therefore be protected from undesirable ambient conditions
(water, small foreign objects).

5.2 Connection
The removable terminals of the KF-series 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.
