5、 the output stage is switched off. DC-detection The DC-detection circuit monitors all 6 outputs for DC. Whenever one or more outputs contain DC for more than 1 second, the circuit will be activated. A positive voltage will activate transistor 7710 and pin 10 of connector 1301 will be pulled down. In

6、 case of a negative voltage, transistor 7716 will be activated, which in turn activates 7710. The set microprocessor will take further action. 3104 217 07180 bl110 MECHANICAL EXPLODED VIEW MECHANICAL PARTS LIST & SCREWS 83104 211 29861SPRING 6 CHANNEL 9-D2.3 x 8 103104 211 29881EARTH SPRING Note:Onl
