2. EXPLANATION OF OPERATION 2.2. Automatic cutoff The MAGSCREEN is supplied by an external box through the control of MAGLIFE C PLUS. The "automatic cutoff" board realize the supplies communication system according to the signals given on the optical cable from the MAGLIFE C PLUS. The main voltages +12V, -12V and +5V arrive from the connector J3 (D8). They are protect by fuses F1, F2 and F3 (D6). The capacitors C6, C7 and C8 (C7) are present to delete the electromagnetics radiations.
