There are two lights on the power supply of the computer gongs processing center unit. One is the power indicator light, which is green; the other is the power alarm light, which is red. The power supply unit here includes power input unit and power control part.
First of all, we should know that when the power supply of Dongguan mold machining center cannot be connected, if the power indicator (green) is not on. The fuses F1 and F2 of the power supply unit have been blown. This is due to high input voltage, or the components of the power supply unit itself have been damaged.
The input voltage is low. Please check the voltage entering the power supply unit. The allowable voltage value is ac200v + 10%, 50Hz ± 1Hz. The power supply unit is not good, there is element damage in it. The power indicator light is on, and the alarm light is also gone, but the power supply cannot be connected. Dongguan machine parts processing at this time because the power on (on) conditions are not satisfied. By the following switching circuit, the power supply conditions are as follows:
There are three conditions for the power supply of Dongguan large CNC machining center: first, the source on button is closed. Second, the power off button is closed. Third, the external alarm contact is opened.
The alarm light of power supply unit of Dongguan large CNC machining center is on: the fuse of 24 V output voltage is fused, and + 24 V voltage is used on 1.9 “display screen, as shown in the figure below. Check whether + 24 V is short circuited to the ground.
