The electric elements on the automatic feeder shall be installed and operated according to their operating instructions, and their actions shall be accurate, reliable and flexible. The customer should provide an over-voltage protection device for power supply of this product.
In order to ensure the safety of working environment, please mount an emergency stop button at the place near the grinding machinery for convenience of workers' operation. The above schematic diagrams are only the running principle for a single machine of this product. The interlocking and linkage between the front and back technological equipment should be considered for design of control technological flow.
Prior to first startup, it is necessary tore move two cartridges clamping the magnetic gate at first, and the function of the cartridges is convenient for transport (when mounted in the air cylinder with magnetic gate).
After the feeder has been installed to its position, it is unnecessary to start the grinding machine for first startup and commissioning, so the starting and stopping switch shall be changed over to the starting position, to check firstly whether the feeding adjusting gate is being opened slowly or not.
The action procedure of the feeding adjusting gate is: quickly close it, and slowly open it within time delay for several seconds after the signal of the gate closed to its position has been detected. If the feeding gate on the hammer mill cannot be opened jet within about 40 s after startup, please shut down the power supply of the controller, and check the step motor for heat generation, and whether the switch of gate opened to its position is wired correctly or not, and the wiring in the controller of the step motor is loose or not. If the wiring is correct, but the step motor is heated up, so it indicates that the wiring of the step motor is wrong, and it is all right only by exchanging any two lines among U, V and W.
After the feeding adjusting gate works normally, please confirm whether the frequency of the frequency converter is normal or not, whether the feeding motor works normally or not.
After above several problems have been solved, the feeder can be put into normal operation.
