The products are constantly being modernized and optimized. As a result of recent upgrades, an economical mode of operation has appeared, which differs from the main one by the algorithm for generating the operating current of the lifting electromagnet, which makes it possible to increase the productivity and efficiency of loading and unloading operations. Basic Mode The voltage of the electromagnet in the main mode is fixed and manually adjustable from 0 to 230 Volts. The default is 230 Volts. The current decreases during the working day as a result of the heating of the electromagnet coil. At elevated ambient temperatures and work intensity, the electromagnet heats up to the maximum temperature before the end of the working day. It is possible to extend the time of optimum performance by decreasing the voltage below the rated voltage. Thus, the performance of the electromagnet is maximum on a cold magnet and minimum on a hot one. When the coil is heated under the influence of a fixed voltage, the current, having reached the corresponding value, will begin to decrease, reducing the performance of the electromagnet. Summing up the above, the following disadvantages can be identified: different performance on a cold and hot electromagnet; high operating temperature, as a result of which the electromagnet overheats and, as a result, its failure. Economy mode The operating current of the electromagnet in economy mode is set automatically and is approximately 70% of the nominal. The correspondence between the hot and cold solenoid currents is given in the operating instructions for the control unit. During operation, the control unit maintains the current at a certain level, regardless of the heating of the electromagnet , and the supply voltage does not exceed the rated voltage of 220 ± 10% Volts. As a result of the operation of the electromagnet in the economical mode, the performance is equalized during the working day, the service life of the electromagnet is increased, the operating temperature is reduced and the risk of electromagnet failure is reduced. Overheating of the solenoid coil is indicated by a sound-visual alarm, which is very important when working with a hot load. We recommend working in basic mode if you need maximum performance for a couple of hours of work, and in economical mode - for long-term work with average performance, or for transferring hot loads.
