The ball press forging itself should be kept well grounded to prevent electrostatic accumulation on the ball machine. The power cable, communication cable, and video cable should be properly connected during installation. When connecting the cable, carefully refer to the installation instructions to confirm the communication mode and corresponding pin definition. Generally, the equipment should be installed in the later stage of construction to avoid a large number of dust in the construction site into the ball machine, which directly affects its use effect and life.
In addition, additional attention should be paid to the following considerations:
In order to ensure the normal operation of the forging of the ball press, the power supply should not be lower than the nominal value of the input voltage of the ball press. When the nominal value is 24VAC, the voltage fluctuation should not exceed ±25%. The common working voltage of ball press forgings is 24VAC. There are 220VAC models on the market, which essentially have a transformer built into the ball cover to supply power to the press forgings after changing the pressure. Wiring should emphasize strong, weak current separate, in order to avoid the interference of strong current to weak current. The internal space of the ball press forging is limited, and the built-in transformer makes the strong and weak electricity coexist, thus affecting the weak current signal. In addition, the built-in transformer will increase the heat dissipation burden, which increases the possibility of the built-in circuit burning out. Depending on the site environment, you can choose from local 220VAC to 24VAC, or remote voltage change or centralized power supply. When centralized power supply, full consideration should be given to the loss of electric energy by transmission lines. Select equipment with high output power and increase the output voltage appropriately to bear the line voltage drop. For example, select 28VAC output to power the remote ball press.
Are the ball press forgings adequately powered? It can be tested by multimeter. The method is to measure the voltage of one end of the power line of the forging of the ball press with a multimeter when the load (ball press) is opened, and observe whether the voltage is within the permissible range of the ball press. In particular, it should be noted that the power consumed by the outdoor ball press is very different when the heater is started or stopped. When supplying power to the outdoor ball press forgings, the maximum power supply required by the ball press in the worst environment must be considered. When the voltage fluctuation of the mains exceeds +5%~-10%, an AC voltage regulator should be installed. UPS can be installed to provide uninterrupted and stable power supply. The grounding of ball press forgings is mainly divided into shell grounding and internal electrical grounding. Shell grounding is mainly used to prevent electrostatic accumulation, electrical leakage, etc., outdoor ball press forging also special external lightning protection measures. Generally speaking, the outdoor ball press forging shell installed on the pole support has naturally formed grounding protection due to the screw connection on the metal support, so it can not be treated specially. The data cables and video cables inside the ball press forgings have been grounded accordingly. Connect the GND end inside the ball press forgings with the ground cables to ensure that the equipment is grounded effectively.
