Q:Does the timer switch call the time to work?: Different timing switches work in different ways. Some do not necessarily support no electricity work.

Q:Photoelectric switch control time relay control AC contactor delay closed: Photoelectric switch relay is through the box or the container within the material flow, fall, making the photoelectric switch infrared or bright or dark optical reaction, the resulting photoelectric signal amplification circuit, so that the photoelectric switch relay closed. Because the flow of material and the speed of the fall soon, the photoelectric switch relay closed off frequently, can not be used by the transmission mechanism, so to install the time relay to extend the signal time so that the transmission mechanism has enough time to run, use. The way they control is such that the normally open contacts of the photoelectric switch relay are connected to the time relay coil to control the time relay. Time relay delay disconnect contact to connect the transmission mechanism of the AC contactor coil, control AC contactor.

Q:If there are three lights can use a microcomputer when the control switch to the different time: Only in this way, it is best to buy three for each one. Hope it helps you.

Q:Why did i press the button a little bit? Solution.: 3, set the first time of the opening time: press the "timer" button, the LCD screen shown above, a "1 open" words, then press "time" and "points" to set a few points A few minutes to open. 4, set the first time of the closing time: then click the "timer" button, the LCD screen shows the above figure, a "1 off" words, then press "time" and "points" to set a few Point off a bit.

Q:Mobile phone every time switch, the time has changed, how will not save, you save the time?: if you still can not remember the time, then you must be fast for the battery speed, in 1-2 seconds must win, it will save the original time

Q:How to switch the time switch off their own time: Mobile phone to find the system settings, point to open, find the timing switch machine word point open

Q:How does the computer view the last time on the switch machine? Please talk about the steps.: "C: WINDOWS schedlgu.txt" in "Run" in the "Start" menu. In the open schedlgu.txt file, "Task Scheduler Service" has been started and the "Task Scheduler Service" has been exited In the time, respectively, corresponding to the boot and shutdown time, is not it convenient? Every day for the record is not difficult. D: If you want every time the switch machine can be clearly recorded, it can be "script + batch" approach. But you have to hands-on, we use the "script + batch" approach to achieve. Simply add two batch-time batch commands on the power-on, shutdown script, and let them start or close the recording time with the system into the C: aaa.txt file. First create two new text documents, respectively, used to record the boot and shutdown information, enter the following command, and then save as ". Bat" file on it. Where the boot batch (start.bat) is as follows: @echo off >> c: aaa.txt echo *** boot record *** >> c: aaa.txt echo. >> c: aaa.txt echo% date%% time: ~ 0, -3 %% Username% >> c: aaa.txt echo. >> c: aaa.txt echo ************** >> c: aaa.txt echo. >> c : Aaa.txt echo. And shutdown batch (shutdown.bat) command as long as the start.bat in the "*** boot record ***" to "*** shutdown record ***" can, the rest unchanged. After the above two batch commands are done, enter gpedit.msc in "Run" in the "Start" menu, open Group Policy, and then click "Computer Configuration → Windows Settings → Script (Startup and Shutdown)", double click "Start", in the Properties dialog box, click "Add" button, and in the "Script Name" column fill in the "start.bat" absolute path, click "OK" button. Similarly set the shutdown script. This can be a switch machine to do an experiment, open the C: aaa.txt file, is not recorded you just shut down and boot tim

Q:When the high voltage isolating switch needs a grounding switch: Inconvenient to install the ground wire, outlet isolation must be ground switch, maintenance ground

Q:1, usually the brightness of the light control switch is determined by road driving, the community can be a little dark start the lighting, how can the current market control of the light switch to adjust? 2, stairway walkway in the sound and light control switch to be delayed, is there any simple way? Thank you!: I did not actually look apart, the specific can not say, just say something about: Light control part of a corresponding resistance (usually connected with the photosensitive resistor), you change its resistance can adjust the sensitivity of the "brightness"

Q:Electric water heater sometimes power leakage switch trip, sometimes over a period of time trip, what is the reason?: one. May be a safe leak protection device bad two. The heating tube is broken
