The igniter is installed next to the everburning lamp for easy ignition. Once the igniter lights the everburning lamp, the PLC issues a command for timely automatic ignition. Manual startup can also ignite according to the ignition program; emergency ignition can be initiated directly at the site without passing through the PLC. After ignition, the PLC and pressure transmitter are in a detection state, while the igniter, high-voltage generator, solenoid valve, and high-voltage self-tester are in a rest state, thereby protecting the high-altitude igniter and electrode arcing device, extending the service life of the high-altitude electric ignition system.
