程控器工作原理（Programmable controller working principle）

程控器工作原理（Programmable controller working principle） 1 LFL1... /LGK16... Programmable controller working principle First, the premise of burner start 1 、 program control reset. 2, throttle closed. The limit switch Z (such as QSN30) in the closed position must transmit the electrical signal on terminal 11 to terminal 8. 3 the control contacts at the closed position of the fuel valve (BV) or other contact points between the terminal 12 and the pressure switch (LP) must be closed. 4. The normally closed contact of the wind pressure switch (LP) must be closed (wind pressure test), that is to say, terminal 4 must output voltage. 5, the pressure switch (GP) and the restrictions on thermal switches or pressure switches (W) contacts must also be closed. Two, start program 1, the A start command uses R (that is, R) to turn off the control loop between terminals 4 and 5 2, (R) closed, the program-controlled machine started to run, fan, motor, contactor coil through terminal 6 to obtain voltage (only pre blowing). After the T7 (2S), the motor or the flue fan also receives the voltage (pre blow or back blow) through terminal 7. 3, the completion of T16 (start with the throttle opening instruction and the time interval between 4-6s), after the terminal 9 are open throttle control instructions, servo motor controller during the operation, no operation, because the terminal 8 is not charged, only when the door is fully open and throttle limit switch A (open position SQN30) to the terminal 8 the power supply controller according to the program of work, to start again. 4, pre briefing time T1 is fully open the door (rated) shortly after the start of the pre blowing time, pressure switch, select the terminal 4 from terminal 13 disconnected or the control unit will be closed (air pressure check, at the same time start) terminal 14 must be charged to the ignition and fuel valves and transformer power supply. 5, in the pre blowing time, the safety function of the flame monitoring loop has
