Include:
21) spout channel check, process include:
21a) go booster switch, and spout indicator light is bright, and receiving spout, indicator light off, connects SM switch, spout indicator light is still
It so keeps bright, disconnects reinforcing switch, receipts spout indicator light is bright, and indicator light off for spout；
21b) go booster switch, and when spout inspection-function switch is placed in " inspection " position, receipts spout indicator light is bright,
Indicator light off for spout, then spout inspection-function switch is placed in " work " position, and spout indicator light is bright, receives spout
Indicator light off；
DK switch 21c) is connected, spout state is constant, then connects XK switch, and receipts spout indicator light is bright, and indicator light off for spout, breaks
XK switch is opened, spout state is constant, then disconnects DK switch, and receiving spout at this time, indicator light off, and spout indicator light is bright；
XB switch 21d) is connected, receipts spout indicator light is bright, and indicator light off for spout, disconnects XB switch, and receiving spout, indicator light off, puts
Spout indicator light is bright；
21e) disconnect SM switch；
22) reinforcing is normally entered and exits, process includes:
22a) enter Afterburning condition；
22b) exit Afterburning condition；
23) emergency enters into and exits from Afterburning condition, and process includes:
When 23a) emergency enters Afterburning condition, spout switch is placed in " spout answers emergency opening " position, then connects that XK switch, TM opens
Pass, JL switch, afterburner ignition coil 33Q indicator light (6), afterburner ignition coil 48Q (7), vaporizer electromagnetic valve I indicator light (8),
Vaporizer electromagnetic valve II indicator light (9), booster pump solenoid valve indicator light (12), spout indicator light (11) and reinforcing signal lamp
It is bright, it receives spout indicator light (10) and goes out, go booster and pump limit switches, at this point, afterburner ignition coil 33Q indicator light (6), 48Q
Indicator light (7), vaporizer electromagnetic valve I indicator light (8), vaporizer electromagnetic valve II indicator light (9) should go out；
23b) shutdown TM switch, booster pump solenoid valve indicator light (12), spout indicator light (11) and reinforcing signal lamp go out, and
It is bright to receive spout indicator light (10) indicator light.
