Press the "source inspection" button and do not release it, the display shows 1.00 (this value is only for reference, there is an error due to the radiation dose of the radioactive source); after the counter tube inspection is completed, the low alarm light is on, and the low alarm signal is output at the same time, driving The personnel task terminal or the commander’s task terminal displays the "nuclear radiation" alarm information. At this time, the SFY-1 three prevention integrated controller "fan port", "filter port", "filter ventilation", "fan operation" and "comprehensive alarm" indicator lights are on , At the same time the blower port is closed, the filter port is closed (observe whether the indicator light is on), and the blower is running; after 2S, a high alarm signal is output, at this time the high alarm light is on, and the driver task terminal or the captain task terminal displays "nuclear" Alarm information, at this time, the three-proof booster fan stops, all shut down machines are turned off, and the engine is turned off. After about 40 seconds, the three-proof device automatically starts the "filter ventilation" working condition, indicating that the "source inspection" function is normal;

Press the "source check" button does not release, the display shows 1.00 (this value is only for reference, affected by the radiation dose of the radioactive source there is an error); Show "nuclear radiation" alarm information, at this time SFY-1 three anti-integrated controller "fan port", "filter", "filter ventilation" "fan operation" "integrated alarm" indicator on, while the fan port shut-off machine, filter shut-off machine on ( Observe whether the indicator is lit), fan operation, 2S output high alarm signal, at this time high alarm light, driver task terminal or captain task terminal display "core" alarm information, at this time, three anti-boost fan stop, all shut down, engine stall, about 40 seconds later, the three defense device automatically turn on "filter ventilation" operating conditions, indicating that the "source inspection" function is normal;

Press the "source check" button, and the display screen will display 1.00 (this value is only for reference, and there is error due to the influence of radiation dose of the radioactive source); after the completion of the counter check, the low alarm light will be on, and the low alarm signal will be output, and the driver task terminal or the commander task terminal will display the "nuclear radiation" alarm information, At this time, the indicator lights of "fan port", "filter port", "filter ventilation", "fan operation" and "comprehensive alarm" of sfy-1 three prevention integrated controller are on. At the same time, the fan port is turned off and the filter port is turned on (observe whether the indicator light is on), and the fan is running. After 2S, the high alarm signal is output, and the high alarm light is on, The "nuclear" alarm message is displayed on the driver's task terminal or the commander's task terminal. At this time, the three prevention booster fan stops running, all shut-down fans are shut down, and the engine is flameout. About 40 seconds later, the three prevention device automatically turns on the "filter ventilation" condition, indicating that the "source detection" function is normal;<BR>
