Before using this product, you must follow the detailed instructions in the system manual to ensure proper use of the product. Safety warnings are used to prevent injury to humans and property. The installer must be a relevant industry or a technician with relevant experience. This manual must be read in detail before installation.
Verify that the selected power supply matches the specifications you require. It is strictly forbidden to install or plug in and pull out the plug when the power is on. Install the location as far away as possible from the heat source. The controller enclosure must be well grounded to prevent electrical shock or to affect controller operation. The steel to be cut must be well grounded and maintain a good connection to the controller casing to ensure the accuracy of the height control.
Do not collide or vibrate strongly to avoid damage to the product. Do not disassemble the torch height controller or change its internal structure to prevent accidents or malfunctions. This product adopts 32-bit arm as the core and two sets of 3-digit digital tube displays, which adopt digital control mode. The linear adjustment device is not included inside, which greatly improves stability. The speed parameters can be modified, and can be modified arbitrarily according to the power supply and lifting mechanism.
The circuit adopts the chip technology, there is no adjustable device inside, and the full digital control technology ensures the high reliability of the product. The operation is simple, and the two sets of digital tubes respectively display the set arc voltage and the actual arc voltage, which are simple and intuitive.
There are 3 knobs for setting parameter operations. Simple and convenient interface, suitable for all plasma cutting CNC systems, can also be used alone. Adopt the proximity positioning mode of the proximity switch. Pwm output, 255 speed adjustable, precise control of motor speed, multi-speed current setting, short circuit protection. The anti-collision function of the cutting tool, when the cutting nozzle touches the steel plate, the controller will quickly lift the cutting tool a certain distance to effectively protect the cutting nozzle.
All input and output are opto-isolated, plasma voltage feedback adopts linear opto-isolation, independent isolated power supply, and can be very compatible with imported plasma power supply of each brand with its own voltage divider. Integrated arc start success judgment function, arc start success feedback function. Power requirements: DC 24 V ± 10% 3 A / 50 Hz. Applicable motor: 24 V DC brush motor.Initial positioning mode: proximity switch or mechanical switch (normally open normally closed through jumper cap setting). Maximum control accuracy: ±1 V. Box size: host 145 X 90 X 42. Panel: 120 X 55 X 40. Working environment temperature: -10 60 ° C.
Detection system: isolated arc voltage divider. SF-HC25G arc voltage height controller has no special port. Four wires are required from the voltage divider of the SF-HC25G height adjuster and the plasma power connection. The two wires are at the port where the plasma starts to arc, and the plasma cutter will have it.The arc voltage signal is two lines divided into positive and negative poles. If the plasma power supply does not have a dedicated port, the plasma power supply housing needs to be opened and connected from the secondary rectification inside the plasma power supply, which is the original arc voltage of the plasma power supply. You only need to connect the ground wire because the interference from the plasma power supply is too large. The ground wire needs to use a copper rod with a diameter of 50 mm or two angle steels with a length of 2 meters. Connect to the housing of the plasma power supply. There are many options, including China Post.
