2. Safety directives
We have taken great care in design and manufacture of our conveyors in order to ensure smooth and safe operation.
You, too, can make an important contribution towards safety at work. We therefore ask you to read these brief operating
instructions completely prior to commissioning the system. Observe the safety directives at all times!
Attention
This warning sign indicates safety directives. Non-observance of such warnings may cause serious injury or
even death!
Caution
This warning sign indicates safety directives. Non-observance of this warning may cause minor injury or
material damage.
Notice
This hand indicates useful tips for operation of the conveyors.
Make sure that all persons working with or at the equipment also read the following safety directives carefully and follow
them!
These Operating Instructions only apply to the equipment types indicated on the cover page.
They must be available at all times at the place of installation of the conveyor.
If the conveyor is to be used in a humid or wet environment (wet area) make sure that the required degree of protection
is provided.
Notice
For comprehensive information on the full range of control devices please refer to the 'Control Units' operat-
ing instructions.
Any commissioning, retooling, maintenance and repair work shall be carried out by qualified and authorized personnel
only (see also 'Operator's duties' in this section).
For installation, maintenance and repair work all poles of the power supply must be disconnected from the conveyor in
compliance with VDE provisions.
Any work on the electrical equipment shall be carried out exclusively by a professional electrician, or by instructed
persons working under the supervision of a professional electrician, according to electrotechnical rules.
Attention
Risk of injury and electric shock hazard!
•The equipment user and operators shall ensure that only authorized personnel works at the conveyor.
•Any changes that have occurred on the feeding system affecting safety shall immediately be reported to the
user.
•Operate the conveyor in perfect condition only.
•Use the belt conveyor only for its intended use.
•Observe the accident prevention provisions VBG 10 for continuous conveyors and VBG 4 for electrical equip-
ment and components"
Machine hazards
•If the belt conveyor comes into contact with moisture or liquids there is risk of electric shock.
•Make sure that protective earthing of the power supply system is in perfect condition.
•Never operate the conveyor without guards and cover panels in place!

Intended use
The intended use of the belt conveyors is the feeding of parts.
The shortest side of such parts must be at least 5 mm long. Special versions or accessory equipment are available to
modify the belt conveyors for use with parts having smaller side lengths (> 0.5 mm). If necessary, please contact the
manufacturer.
Caution
Smaller parts may get under the belt and cause damage or failure of the belt conveyor.
Parts handled with standard belts must be dry, clean and without sharp edges. The handling of sharp-edged, oily, wet
or hot (>70°C) parts requires the use of special belts.
Caution
For handling parts that may fall over, roll or slide, be sure to install sufficiently dimensioned side guides or
slatted belts from our range of accessories.
The parts must not drop on the conveyor belt from height. The maximum permitted impact energy is 0.1 J.
If in doubt, please contact the manufacturer.
The belt conveyors are designed for horizontal transport at maximum loading. A slight inclination of the conveyor is
possible in some cases. Please consult the manufacturer to determine what is possible for your specific application!
For permitted belt loading see Technical Data in section 1.
Noise emission
The constant sound pressure level is 70 dB(A) max. Specific part handling applications or belt designs may result in
higher noise levels. For such exceptional cases noise abatement options are available from manufacturer.
Equipment user's duties
Commissioning, retooling, maintenance and repair work shall be performed by qualified and authorized personnel only.
We distinguish between four qualification levels:
Qualified personnel
refers to persons who are familiar with installation, start-up and operation of the conveyor. Their qualifications are ap-
propriate for their activities.
Authorized personnel
refers to qualified personnel that has been assigned a clearly defined task by the user of the belt conveyor.
Qualified electrical worker
According to IEC 364 and DIN VDE 0105 Part 1, the term 'qualified electrical worker' refers to persons who, through
their professional training, know-how and experience and through their knowledge of applicable standards are able to
assess the work assigned to them and to recognize potential hazards.
Instructed person
According to IEC 364 and DIN VDE 0105 Part 1, the term 'instructed person' refers to persons who have been instructed
in the tasks assigned to them by a qualified electrical worker. These persons have also been briefed on potential dangers
resulting from inappropriate behaviour, and on the requisite guards and precautions to be used/taken.

2.1. Applicable directives and standards
The hopper has been manufactured in accordance with the following directives:
•EC Machinery Directive 2006/42/EC
•EC Low-Voltage Directive 2014/35/EU
•Electromagnetic Compatibility Directive 2014/30/EU
We assume that our product will be incorporated into a stationary machine. The requirements of the EMC Directive
must be satisfied by the user.
The applicable standards are specified in the Declaration of Incorporation.
3. Design and functional description of belt conveyors
The belt conveyor bodies are made up of either special T-slotted aluminium profiles (FP120) or a folded sheet metal
body (FK120).
Fig. 1: Conveyor body types
Up to belt widths of 200 mm the conveyors can be fitted with knife edges at the entry and exit ends. If a knife edge is
fitted it is not possible to arrange a drive station at the respective location. Belt tension and tracking are adjustable by
means of the return roller arranged underneath the knife edge (see arrow).

For belt drive a number of motors are available for constant and variable speed. The motor may be arranged at the entry
or exit end of the belt or in the middle. Drive stations can be attached to the belt conveyor in different ways. Control of
the belt feeder is effected, depending on motor type, by motor protection breaker, electronic control devices or variable-
frequency control units.
Fig. 3: Drive configurations
After loosening the setscrews (see arrow) you can rotate the drives on the driving roller shaft for variable motor position-
ing. Re-tighten the setscrews to fix it back in place. Adjusting the chain drive may affect chain tension. Therefore be sure
to always check and adjust chain tension before restarting.
Notice
For information on the control devices please refer to the separate 'Control Units' operating instructions.
The brackets of the return station come with or without edge protectors. Brackets without edge protectors are smaller
in size and are used when parts or side guides extend beyond the brackets, or for belts installed in hopper-type feeders.
Belt tension and tracking are adjustable by means of the return roller (see arrow).
Fig. 4: Return station brackets
Depending on the application on hand the different belt feeders can be fitted with various accessories.
These include cleated belts, anti-slip belts, reversible belts, angled belts, ESD versions, pharmaceutical versions, split
conveyor bodies, side guides, top covers, sealing bars, supporting rollers, dirt trays, various support types etc.
