This description contains the necessary information for the correct application of the product describedbelow. It is intended for use by technically qualified personal.Qualified personnel are persons who, because of their training, experience and position as well as theirknowledge of appropriate standards, regulations, health and safety requirements and working conditions,are authorised to be responsible for the safety of the equipment, at all times, whilst carrying out their nor- mal duties and are therefore aware of, and can report, possible hazards (Definition of qualified employees...

Notable Features: Operating manual > SFA 06/...-1 Adjustable output frequency, independent of mains frequency Օ Constant feeder throughput irrespective of mains fluctuations 1.0General Track control Օ Regulation control, automatic frequency search (resonance) The AViTEQ SFA... range comprises special, adaptable controllers for use withvibratory feeders. The units generate an output frequency, to drive feeders, that is independent of mains frequency and so exact tuning with springs is not nec- essary. The feeders also run quieter because of the sinusoidal output signal. The adjusted output...

Operating manual > SFA 06/...-1 8.0 Control Elements 8.1 Settings The six buttons and a LED display found in thefront panel, are used for operating and setting up the unit. All operating methods and adjustable parameters can be set up through this panel. The Iӓ and Oӓ buttons are used for switching the unit ON and OFF, however, these do not providemains isolation, they simply inhibit the powersemiconductors The Pӓ, Fӓ and Cursor Buttonsӓ are used for parameter adjustment. Parameters are set by using menu controls which are called up by en- tering operator codes. The functions are de-...

Operating manual > SFA 06/...-1 9.0 Commissiong 9.1 Preliminary steps Check that the unit is correct for the local mains supply (type label information) and that it is correctlyrated for the feed system. Օ Connect the controller according to the connection diagram Adjust the set point to zero Օ Close enable (when used) The unit is now ready to operate and can be switched on (mains, enable). > Using the control units described in this document, it is possible to adjust the feed systemso that it runs at resonance. In this condition it is possible to obtain excessive output for a very low set...

Operating manual > SFA 06/...-1 10.2.4.1 Instructions for using regulation mode An accelerometer must be fitted to the vibratory feeder in order to run in regulation mode. Օ All vibration signals, that are picked up by the accelerometer, are used by the regulator circuit. Straysignals generated by neighbouring machinery, a flimsy accelerometer mounting, or an unstable sup- port frame, can cause incorrect regulation to occur. It is especially important to ensure that there are no external influences, of this type, during the automatic frequency search routine. Resonant frequencies: It is...

Operating manual > SFA 06/...-1 Linear feeder example > SensorSwing DirectionMounting BlockMoving Part Fixed Part 1 2 1 = small amplitude because sensor is mounted vertically.2 = larger amplitude because sensor is mounted in the same plane as the springs.The controller, together with the sensor fitted on the feeder, produce a feed back loop, whereby the signalgenerated from the sensor determines the control range of the set point i.e. the regulator controls the feeder so that the effective value (feeder power or intensity of vibration) relates to the provided set point value. Because the...

Operating manual > SFA 06/...-1 Because of the vastly different acceleration values of various feeders there is a big difference in the feedback signals, which makes scaling necessary. 10.2.4.4 Instructions for setting up the controller in regulation mode Connect control unitInstall sensor and connect to controller 10.2.4.5 Determining the resonant frequencyManual setting of the vibrating frequency It is essential that the output frequency is adjusted with the set point set at a low frequency, otherwise onhitting the resonant frequency it is possible to achieve a high amplitude with a low...
