9 Protection System The protection system is based around Q0-Q. Under normal conditions Q0 Q will be off. t turn-on 0 will charge through R towards the +LT supply rail. The voltage is fed to the base of Q via. When the voltage across 0 reaches approximately 0V Q will turn on and thus turn on Q. Resistor/diode network R & connected between Q collector and Q base provides positive feedback in order to make the turn-on/turn-off of Q more defined. The collector of Q is connected via R R0 & Q to the coils of relays RLY-. Transistors Q0 and Q are connected in such a way that a voltage of -0mV applied to the emitter of Q0 will turn on Q0 and hence Q. This will rapidly discharge 0 and hence turn off Q and Q thus opening the output relays. Similarly Q is connected such that a base voltage of +0mV will turn it, and hence Q, on with the same resultant opening of the output relays. The output of each channel is fed via resistors R and R into -9 and then via 9 and 0 to Q base and Q0 emitter respectively. The combination of -9 with R and R forms a low-pass filter, and so at signal frequencies -9 will have no voltage across it. In the event of a offset appearing at the output, however, -9 will charge to a voltage, turning on Q & Q or Q0 & Q depending upon the polarity, and hence opening the output relays. The Network consisting of R, R and provide the rapid turn-off feature of the protection system. R is connected through the 90 degree thermal switch to and, which are connected to the secondaries of the mains transformer. The union of and will, therefore, show a full-wave rectified version of the secondary voltage. This is averaged by to a negative voltage, reverse biasing and, therefore, having no effect on the protection system. Should one of the thermal switches open, or the power be turned off, will be rapidly charged towards the +LT rail via R, forward biasing, turning Q on and opening the output relays. If there is no rapid turn off, suspect R (00k) this may be open circuit. It is worth noting that failure of this resistor will render the thermal shutdown useless.
