Notes for Pacemakers and Defibrillators
Afag vibration conveyors are tested in accordance with regulation 15 of the German Statuto-
ry Accident Insurance Association [Deutsche Gesetzliche Unfallversicherung, DGUV] (previ-
ously BGV B11 of German Accident Prevention Regulations). The permissible values of ex-
posure area 2 are not exceeded, therefore no measures are required pursuant to Section 4
(2) of the DGUV regulation 15. The definitions of Section 12 “Indirect Effects, Medical Im-
plants” remain unaffected by the above.
The alternating magnetic fields that occur in the immediate vicinity of certain vibration con-
veyors may affect the proper functions of active implants, i.e. pacemakers and defibrillators.
Anyone with active medical implants, for which no individual risk assessment has been pro-
vided, must observe the specified safety distances to the vibration conveyors. The distances
each relate to the position of the upper body and the active medical implant relative to the
field source.

Description of the device
2.1
General
The BF bowl feeder is used in conjunction with a bowl for storing, transporting, separat-
ing and sorting bulk goods. The transport motion is generated by vibration. The parts are
moved in the transport direction by micro-jumps.
The mass and the moment of inertia of the bowl used should not exceed the values and
tolerances specified in section 2.3 as otherwise the goods will not be transported as well
as possible.
The BF is designed in such a way that if the tolerance ranges for the mass moment of
inertia and mass specified in section 2.3 are observed, no mechanical tuning is required.
If these tolerances are exceeded, mechanical tuning by fitting or removing leaf springs
will be necessary. Please note, however, that in this case perfect transport will no longer
be guaranteed. In addition the vibration force compensation system will be adversely af-
fected in this case, which means that more vibrations will be guided into the sub-
structure and this may affect the area around the machine.
NOTE
BF feeders are to be operated in conjunction with an Afag control
unit. This is the only combination that will guarantee perfect
transport characteristics.
