1 For Your Own Safety
1 For Your Own Safety
1.1 Intended Application
The pulse generators of the DG type series generate
pulses, the frequencies of which depend on the rotation-
al speed. The pulse generators are particularly suited for
application if high accuracy of operation, long service life
as well as wear and corrosion resistance are important.
The pulse generators meet the high requirements of the
relevant regulations.The device is intended for use in
stationary installations and in vehicles.
Applications other than specified and unauthorized mod-
ifications to the device or its components can lead to in-
jury to persons and damage to the device, for which the
manufacturer is not liable.
Make sure that the intended use is not impaired in any
way, even after unexpected outside influence on the de-
vice.
"Intended application" particularly means that any work
performed with or on the device is to be carried out in
accordance with these operating instructions. Only
skilled persons who are familiar with the Regulations
on the Prevention of Accidents as well as the other
generally accepted safety rules are allowed to work on
this device.
You protect yourself and prevent damage to the de-
vice when you apply the device as intended!
1.2 Symbols
Please pay particular attention to the text passages that
are marked with the following symbols:

2 Transport, Packing, Storage and Disposal
2.1 Transport and Packing
Choose a suitable packing when you send the device or
components to Vossloh Kiepe GmbH e.g. for repair.
Take great care that the device is protected against
shocks and humidity. In this way damage to the device
due to transport is prevented, for which the manufactur-
er is not liable.
2.2 Storage
Avoid significant variations in temperature as this can
lead to condensed water, which might damage the de-
vice.
The permissible storage temperature is between -25°C
and +70°C.
Attention!
Keep the device clean and dry.
2.3 Disposal
Reuse the packing material, if possible, or dispose of it
in an environment-friendly way.
Send defective devices and components to Vossloh
Kiepe GmbH for correct recycling or disposal (see com-
pany address on back cover).

3 Design and Function
3 Design and Function
The pulse generators of the DG type series generate
pulses, the frequencies of which depend on the rotation-
al speed. The pulse sequences are analysed by rota-
tional speed monitoring devices. The pulse generators
have a proximity-type design and work contactlessly.
They are particularly suited for application if high accura-
cy of operation, long service life as well as wear and cor-
rosion resistance are important.
3.1 2-Wire Pulse Generator according to
NAMUR-EN 50227
Essentially, these pulse generators consist of a transis-
tor oscillator, the high-frequency stray field of which
makes up the response zone. When a metallic object is
immersed into the effective area of the stray zone, the
resonant circuit is short-circuited, and its internal resist-
ance becomes high-impedance. The oscillations stop
and the current consumption of the pulse generator de-
creases. This current change is analysed by the rota-
tional speed monitoring devices.
3.2 PNP Switching 3-Wire Pulse
Generator
These pulse generators differ from the NAMUR pulse
generators by an additional downstream flip-flop, which
effects a change of the output potential from GND to
+UBwhen the active zone is damped. These pulse gen-
erators can also be directly connected with a PLC.

5 Mounting and Dismounting
5 Mounting and Dismounting
5.1 Scope of Supply
The pulse generators are delivered ready for operation.
The fixing nuts (1) or the plastic clip (2) together with the
weld-on plate (3) are included in the scope of supply
(see fig. 5-2).
5.2 Mounting
Danger to life – electric shocks!
The mounting and the electrical connection
may only be carried out by skilled electri-
cians.
De-energize the plant before the mounting.
Prevent unintentional reclosing of the plant.
Cover the adjacent, live parts in a shockproof
way.
5.2.1 General Mounting Instructions
The pulse generators are to be so installed that one or
several metal parts (Fe metals, if possible) can rotate
past the head (4) of the pulse generator within the re-
sponse distance (see fig. 5-1). One pulse is generated
per metal part. Pulse multiplication via symmetrical ar-
rangement of several metal parts is recommended for
low rotational speeds. The metal parts should at least
have the dimension of the head (4) of the pulse genera-
tor, and the distance between any two parts should not
be below the double diameter of the pulse generator.
The pulse generator is fastened with two fixing nuts (1)
or by means of the enclosed plastic clip (2) and the
weld-on plate (3) (see figs. 5-1 and 5-2). The pulse gen-
erators are also suited for a flush fitting. They can be
screwed directly into a thread.
In order not to influence the responsiveness of the pulse
generator, the distance between the head (4) of the
pulse generator and the metallic machine parts has to
be at least 24 mm for M 18 pulse generators and 30 mm
for M 30 pulse generators.

5.2.2 Mounting and Connecting the Pulse
Generator
1. De-energize the plant before the mounting and pre-
vent unintentional reclosing of the plant.
2. Mount the pulse generator with due regard to the
mounting instructions in section 5.2.1 and the me-
chanical data in section 4.1.3.
3. Connect the pulse generator in accordance with the
wiring diagram (see fig. 5-1).
