(3 ) Asahi remote switch button pressed to stay more than three times can not boot, just about off the power switch K401, over a period of time to boot. Description is to protect the circuit from the control . Analysis shows the same circuit according to the principle of the protection circuit when the silicon can be controlled from the control V604 , which have only the anode voltage , the thyristor is always in the ON state, the machine always remain in the standby state can be switched by remote control should be focus on examination of X -ray protection circuit , beam current protection circuit and control circuit protection .eyLservice manual download site
