EPB-C30 is used as a magnetizing and demagnetizing current controller for all models of
lifting system which is comprised of 2 or more battery activated electro permanent
It is powered with batteries and outputs a few pulses of direct current to all modules of the electro permanent lifting magnets in the lifting system. Each current pulse lasts in a given time interval.
Operators can simply turn a knob at EPB-C30 to adjust the magnitude of the current to generate 3 different levels of attractive forces to work load. The lower level can be used to attract thin sheet metal one at a time from a stack, without clinging additional sheets underneath.
In order to get a maximum safety margin, EPB-C30 outputs magnetizing currents in two stages which are activated by a signal issued from an electronic sensor. First magnetizing current is not big enough and make all modules of the electro permanent lifting magnets partially magnetized only and therefore there is a portion of the rated lifting capacity to the load beneath them. A few seconds after the lifting system elevated off ground, the second and the bigger magnetizing current takes place. By now the entire electro permanent lifting magnets would be saturated with magnetization and obtain full rated lifting power. So, if the lifting system can lift a load after the first and partial magnetization, it can absolutely lift the load safely after the second and full magnetization.
After the first magnetization an intermittent alarm would sound to remind operators that the modules of the electro permanent lifting magnets are partially magnetized only and a portion of the rated lifting capacity is achieved. A few seconds after the lifting system lifted, the intermittent alarm would then stop. This indicates that the second magnetization occurs and the lifting system now has full lifting capacity. On the contrary, if the intermittent alarm continues to sound, it is an indication that an issue has occurred during the second magnetization which should not have taken place. In such case, it is dangerous to continue the lifting operation. You must immediately stop the lifting operation and have a qualified engineer fix it, or contact Armstrong Magnetics for technical assistance.
While the lifting system of electro permanent lifting magnets is lifted from ground, a sensor instructs the EBP-C30 to not output demagnetizing current to the modules of the electro permanent lifting magnets even if the operator presses the DEMAG buttons. With this safe feature design, no one can release the load from the lifting system when it is lifted. Operators can only release the load after the lifting system is laid down to the ground.
EPB-C30 detects the current values of the first magnetization, the second magnetization, and the demagnetization every time they occur. If any of them has not reached a set value, a continuous alarm would sound, and/or the light of “PARTIAL MAG”, “FULL MAG” would flash.
Customers can also have the option of having a wireless remote control EPRC-3 to operate the lifting system of electro permanent lifting magnets.
