Commissioning
Preparations
Attention
Make sure that the machine frame (rack, substructure, etc.) is connected to the protective earth conductor
(PE). Protective earthing has to be provided by user as necessary.
Attention
It is imperative that the vibrating motor be connected to the equipotential bonding system of the overall equipment be-
fore commissioning.
The adaptation points are marked with earth symbols.

Attention
Electrical connection of the vibratory feeder must be made by trained professional electricians only! When
making any change to the electrical connection make absolutely sure that the 'Control Units' operating in-
structions are duly observed.
Verify that
•
the vibratory feeder is arranged freely without contact to any solid body.
•
the bowl is firmly bolted in place
•
the vibratory feeder connecting cable is plugged into the control unit.
•
The available electricity supply (frequency, voltage, power) must correspond to the connection data of the con-
trol system (see rating plate on the control unit).
Plug the cable of the control unit into a power socket and operate the power switch to energize the control unit.
Notice
For vibratory feeders that are supplied as a completely set-up system the optimum feed rate has been fac-
tory-set. It is marked with a red arrow on the dial of the rotary knob. In this case set the rotary knob (or
keys) to this mark.
Optimum tuning is achieved when the desired feeder speed is obtained with a controller setting of 80 %. In case of
larger deviations (> +/- 15%) you should re-tune the system.
Tuning
Vibratory feeders are factory-tuned for standard feeder bowls (without orienting devices).
To ensure optimum sorting behaviour the vibratory feeder has to be fine-tuned for the actual local operating condi-
tions.
Tuning is done by adding or removing leaf springs and spacers.
First check that the correct control unit is connected (see table with frequency, voltage and power ratings in Section 1).
Now perform following steps:
•
Unscrew the sheet metal enclosure. Firmly tighten all spring and bowl fastening screws. For the tightening
torque of spring fastening screws refer to section 1 'Technical data'.
•
Check that the magnets are compatible with the voltage and frequency ratings specified under Technical Data.
•
Measure the air gap. Adjust the air gap to the correct setting if it doesn't match the values specified under Tech-
nical Data.
•
Fill the bowl with parts. Switch the vibratory feeder on and set the feeding capacity to 90% via the rotary knob
(or keys).
•
Loosen the bottom fastening screw on one spring pack (by about a quarter turn or half turn).
