3、风机全自动燃烧机在锅炉系统中,受锅炉控制器(温度、压力、水位等参数)的控制,可自动的启动和停止,通常无专人专职看管。原电路将风机接在TR、TB之前,并且不受PROG-110系统的控制。见图1,只要QS闭合风机就不会停止(除非损坏),TR、TB的通断对风机毫无影响;若断开QS,虽然风机停了,但整个燃烧机也因失去电源而停止工作,无论TR、TB在何种状态也启动不了燃烧机。
3, automatic fan blower in the boiler system, by the boiler controller (temperature, pressure, water level and other parameters) control, can be automatically started and stopped, usually without full-time custody. The original circuit connected the fan to TR, TB and was not controlled by the PROG-110 system. See Figure 1, as long as the QS closed fan will not stop (unless damaged), TR, TB on and off has no effect on the fan; if you disconnect the QS, although the fan stopped, but the entire burner also lost power due to stop working , Regardless of TR, TB in which state can not start the burner.
