2Obtain the AC power of out of phase, thereby produce the magnetomotive opposite, linear electric motors 11 are moved to closing the curtain direction along guide rod 15, moving to the eve of closing the curtain end, make linear electric motors 5 stop to move because of limit switch normally closed interlock KB2 is disconnected with above-mentioned direction.
The course of work under other curtain working method repeats no more.
The curtain end of run, after time-delay in 1 minute, CPU can pipe after three, withdraws from the curtain attitude automatically and be back under the working method of the former setting of light modulation attitude to work on.
Under the light modulation attitude normality working method and the situation of not lighting a lamp, press mode key S earlier
1(or AJ
1) and then press key point S
2(or AJ
2) pipe after, CPU just switches to the speed governing attitude, and places and transfer the opening speed operating conditions, this moment CPU P1.3 pin output low level, charactron LED
4Normal dark.The pulse signal of P1.0 output certain frequency, its frequency is directly proportional with the opening speed of Set For Current, makes left indicator lamp LED
2By this frequency scintillation, P1.1 exports high level, makes right indicating lamp LED
3Extinguish.
Click key point S
2(or AJ
2) buzzer FM can send and key in tweeting sound and make the opening speed value in the CPU internal memory promote one grade simultaneously, meanwhile, left indicator lamp LED
2Flicker frequency is obviously accelerated, and presses key point S again
2(or AJ
2), can make opening speed promote one grade more again, left indicator lamp flicker frequency is obviously accelerated again.When opening speed was raised to maximum, buzzer FM also can follow and send the indication sound that intermittently pipes, if think that speed is too big, then can press crucial S
3(or AJ
3) order the opening speed in the CPU internal memory to descend one grade, meanwhile, left indicator lamp flicker frequency is also slack-off thereupon.When speed drops to hour, buzzer FM can send intermittently tweeting sound.
Press mode key S
