    摘要: A controller which controls the operation of the solenoid valve that regulates the flow of gas to the burner within a fuel-gas fired burner system is disclosed. The controller performs a number of diagnostic tests on the system components and provides an output in the form of a series of pulses having a specific code"embedded" therein to identify a fault condition when it occurs. The series of pulses is applied to a light emitting diode. A code reading device having an optical sensor and a liquid crystal display is provided to intercept the light pulses emitted by the light emitting diode and to"translate" the code embedded therein so that the specific fault condition can be identified and displayed on the liquid crystal display.
