1 Safety instructions 1.1 Notes on symbols and instructions Symbols: Assembly and commissioning must be carried out by qualified person- nel only and according to these operating instructions. Please observe the meaning of the following symbols and notes. They are grouped into risk levels and classified according to ISO 3864-2.
These operating instructions must always be kept ready to hand where the BF is operat- 1.3 Appropriate use Afag BF bowl feeders are designed only for storing, transporting, separating and sorting workpieces of varying dimensions, shapes and material variants. Appropriate use also includes observation of all Notes in these operating instructions.
1.4 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.
2.2 Function description Afag BF bowl feeders use a vibration force compensation system based on the counter- vibration principle. In this case a utility weight (1) vibrates exactly opposite to a counter- weight (2). The utility weight is essentially formed by the mounting plate, the bowl and the magnetic anchor, the counterweight is formed by the counter ring and the vibration magnet.
. See section 2.4, Table 1, for the mounting hole dimensions. (see Figure 4) Ideally the devices must be mounted on a plate that can be height-adjusted and rotated around a central column. Suitable substructure components are available from Afag. Page 10 16/05/2019...
Mounting plate Central column Mounting foot Another possibility is to mount the device straight on to a base plate. Suitable Afag standard parts are available for complete station assemblies using Afag linear feeders. 3.3 Fixing the bowl 3.3.1 Central Fixing The bowl is secured to the mounting plate provided for it on the BF bowl feeder using a central mounting screw.

These kinds of bowls should be mounted with some screw, positioned radial to the centre.
3.4 Power supply WARNING ▪ Any work performed on the electrical supply may only be performed by trained, authorised, qualified personnel! ▪ The power supply must be protected by an FI switch (pro- vided by the customer). ▪ The bowl feeder may only be operated with the power sup- ply specified on the name plate.
4 Operating instructions 4.1 Standard operation No further settings are required for standard operation once the control is switched on. An uninterrupted operation only requires the re-filling of the feeder bowl. CAUTION The bulk material must be filled into the middle of the conveyor bowl.

5. If the transport speed only increases when the screw is loosened and does not decrease again even when the screw is fully loosened, the drive unit is too rigidly tuned. In this case, remove a leaf spring and retune the frequency. You must re- move as many leaf springs as necessary until the properties described in point 4) are achieved.
4.3 Torques Tightening torques M in Nm for shank screws with metric ISO control threads and head supports according to DIN 912 or DIN 931: Tightening torques M in Nm Screw Strength class 8.8 Strength class 10.9 Strength class 12.9 14,0 16,5 (M7)
The screws must be tightened using the torque shown in Table 3. During tightening the screws the spacer washers may not be turned. Table 3: Tightening torques for spring installation Type Unit BF20 BF25 BF30 BF35 BF40 BF50 Tightening torque [Nm] R06.0...
5.2 Adjusting the magnet gap To adjust the magnet gap between the oscillating magnets, the casing must be removed and the securing screws of the magnetic anchor) undone. Then the (see Figure 9, Figure 10) appropriate spacer gauges must be slid into the openings provided (Table 7: Adjusting tools) on the counterweight.

Soft-starting, all IRG and MSG types can be mounted in various different ways and offer extra controls for photoelectric barriers, initiator elements, or extern 24VDC signal. For a detailed description of the controllers refer full-range catalogue from Afag GmbH. Third-party controllers can also be used as long as they meet the technical requirements.
