1.1 Intended use
The belt misalignment switches HES and SEL are used
for monitoring the true running of continuous conveyors.
The switches serve to protect the belts from being dam-
aged or destroyed if the belt deviates from its designed
running line. The device is intended for use in stationary
installations and vehicles.
The documentation at hand is to be considered part of
the product and must be retained and be available to the
respective owner/user for the entire service life of the
product. The documentation must be passed on to each
subsequent owner of the product.
The manufacturer is not liable for personal injury and
property damage arising from non-intended use of the
device or unauthorized modifications to the device and
its components. Make sure that the intended use is not
impaired in any way even after unexpected outside influ-
ence on the device.
Intended use refers specifically to the operation of the
device in accordance with these operating instruc-
tions. Work on this device may only be carried out by
qualified personnel who are familiar with accident pre-
vention regulations as well as other generally recog-
nized safety regulations.
By using the equipment as intended, you protect
yourself and prevent damage to the equipment and
its components.
1.2 Design of warnings
Risks are classified in accordance with ISO 3864-2 and
ANSI Z535.6 using the keywords
•“Danger,” “Warning,” and “Caution” in the case of
bodily injury,
•“Beware” in the case of property damage, and
•“Note” to convey general information.
In this documentation, the Risks and Notes are classified
and presented as follows:
Danger!
indicates the immediate threat of danger. Not avoiding
this danger will result in death or extremely serious in-
jury (crippling).

CONFIDENTIAL
2 Transport, storage and disposal
2.1 Transport and packaging
Select suitable packaging when sending the device or
components of the device to Vossloh Kiepe GmbH, e.g.
for repairs. In particular, ensure that the components are
kept clean and protected from shock and moisture. This
prevents damage to the components that may occur dur-
ing transport, for which the manufacturer accepts no lia-
bility.
2.2 Storage
Avoid major temperature fluctuations, as these can lead
to condensation that can cause damage to the device
and its components.
Permissible storage temperature: see Chapter 4: „Tech-
nical data", page 10
2.3 Disposal
Only materials that are not considered hazardous ac-
cording to current engineering practice are used for
Vossloh Kiepe GmbH products. Furthermore, we devel-
op products that can be recycled after intended use. In
our selection of raw materials and components, we favor
reusable materials. This choice of materials used does
not compromise product safety in any way.
Damage caused by storage
Dirt or water getting into the device and exposure to
weather (e.g. buildup of condensation in the device,
sunlight) damage the device and lead to faster deterio-
ration.
Protect the device by storing it in a clean, dry place un-
der stable ambient conditions. If possible, store the de-
vice in its original packaging.

3 Description
Belt misalignment switches are used in conveyor belt
systems subjected to especially severe operating condi-
tions for monitoring the true running of continuous con-
veyors (see section 1.1: „Intended use“, page 5). The
belt misalignment switches serve to protect the belts
from being damaged or destroyed if the belt deviates
from its designed running line. Upstream systems can be
stopped in time to avoid material spillage or operational
malfunctions.
The roller lever (3) of the belt misalignment switch is
made of stainless steel and contains ball bearings for im-
proved handling of lateral forces and impacts. The
48 mm roller diameter means the device can be used at
high belt speeds. All external parts are either made of
stainless steel or have a special galvanized coating.
The roller lever (3) of the belt misalignment switches can
be moved in both directions (see fig. 3-1). By moving the
roller lever (3) the cam discs (11) are turned (see fig. 3-
2). The cam discs (11) operate the switches (7). The cam
discs (11) are adjustable and make it possible to adapt
the switch points to local conditions.

CONFIDENTIAL
The belt misalignment switch, for example, can be ad-
justed in such a way that when it reaches the first switch
point, an advance warning (adjustment range: 5° to 15°)
is triggered and when it reaches the second switch point,
the conveyor belt system is switched off (adjustment ran-
ge: by prying out a cam by 15° to 35°). The mechanical
stop of the roller lever (3) is reached at a deflection of
75°.
Belt misalignment switches are mounted in pairs on the
upper belt in front of the drive roller, on the lower belt in
front of the deflection roller and also on critical spots
where the axis distances are larger or material is
transferred (see fig. 3-3).

Danger of fatal electric shock
Work on the device may be performed only by a quali-
fied electrical technician.
Prior to working, switch off the power supply to the sys-
tem. Ensure that the system cannot be accidentally
switched on. Mask any neighboring components that
may be live to prevent contact.
Beware!
The belt misalignment switches are to be used in con-
trol circuits only.
Beware!
The device must only be operated when all three holes

!
Beware!
Make sure to mount the belt misalignment so that the
belt edge actuates the roller lever (3) in the lower half of
the roller when the belt deviates from its designed run-
ning line. This prevents the belt from sliding over the
roller lever (3) (see fig. 5-2).

where the axis distances are larger or material is trans-
ferred (see fig. 5-2).
1. Prior to working, switch off the power supply to the
system. Ensure that the conveyor system cannot be
accidentally switched on. Mask any neighboring
components that may be live to prevent contact.
2. Secure the belt misalignment switches on the con-
veyor structure (see section 4.4: „Dimensions“, page
13). Secure the belt misalignment switches by
screwing two screws through the long holes (10)
(see fig. 5-3).
In order to minimize roller lever (3) wear, mount the roller
lever (3) in such a way that it is located approximately 10
to 20 mm in front of the belt edge (see figures 5-2 and 5-
4).
3. Fit the roller lever (3) onto the shaft (14).

Danger of fatal electric shock
Work on the device may be performed only by a quali-
fied electrical technician.
Prior to working, switch off the power supply to the sys-
tem. Ensure that the system cannot be accidentally
switched on. Mask any neighboring components that
may be live to prevent contact.
Danger!
Only use connection cables with a diameter of at least
11 mm up to a maximum of 16 mm. The permissible
conductor cross-sections can be found in Chapter 4:
„Technical data", page 10.
Penetration of dirt and water when gaskets
are damaged
If gaskets are damaged, dirt and water can penetrate
into the device and damage the device and its compo-
nents.
Check gaskets for damage before assembling. If the
gasket is damaged, exchange the device cover.
