Q: How to check win7 computer switch machine time: Method Two Open the win7 system in the "Start" menu "Run", and then enter "C: WINDOWS schedlgu.txt", in the open schedlgu.txt file "Task Scheduler Service" has been launched in the ... ... and "task Scheduler service "has been withdrawn from the time, there are respectively corresponding to the boot and shutdown time. Type "C: WINDOWSschedlgu.txt" Method 3, the use of script daily record, after the text file to open directly on the line, the specific method is as follows: For example, record the E disk switch machine time. 1, first of all, create a new text document, change the name "kai.bat" (do not forget to change the name), right edit open, the contents of the following two sub-lines into the middle of the content @echo off Echo% date%% time% boot >> E: switch machine time .txt Create a new switch file 2, and then create a new text document, change the name "guan.bat" (do not forget to change the name), right edit open, the contents of the input content; @echo off Echo% date%% time% shutdown >> E: switch machine time .txt Create the "guan.bat" file 3, then in the run dialog box, enter "gpedit.msc", open the Group Policy, expand the computer configuration, Windows settings, double-click to start, display the file, and then copy the kai.bat; 4, and then start the property where the point to add, browse, add kai.bat, the same token, guan.bat by the above steps to add to the shutdown there.

Q: There is no switch in the trigger after the start of the power can be set to automatically set the time after the arrival of automatic power failure 100 For example, a machine only need to work for a few seconds to complete the action in the action is completed after the need for manual processing at this time need a switch to automatically power off to cut off the power to let the machine to stop working and can manually power Requirements are small equipment Add the time to repeat the action after the device has completed the production action. This is the order in which the time of the repetition of the timing switch is not circulated. When the power is not needed, Standby but not completely off the power of a little confusing hope that we help a lot of problems I am troubled for a long time to find a lot of relay timers are not up to the request Thank you: Simple can use the trip switch, installed in the work surface, when there is a work piece touched when the closure, after the cut off; There is a proximity switch, inductive, electromagnetic, capacitive, photoelectric, and contactor combination, when the work piece is close to open the machine, after processing to complete the work surface automatically shut down the machine.

Q: For example, a week, I play every day, every day switch machine? Can you sleep all the time? If you can sleep, how long is the best sleep?: Do not sleep often, sleep some programs may also open the best is to shut down, sleep not too long

Q: I am a factory electrician, I would like to ask, how to control the total power switch? Mainly at work time the whole plant of the total power open, when the whole plant power supply automatically shut down. (To prevent accidental leakage accident occurred) The total power of the plant is about 200-300kw I used it on some lines Time control switch + contactor control circuit in the working hours of electricity, power off time. But I do not know whether the time control switch can control 300kw such a large contactor, And whether my current approach is the best way, is there any other way?: We are closing the total power when we leave. And each time to check whether the electrical equipment are all closed. And then closed. (Which is required by the Code of Practice for Electrical Safety) is usually the responsibility of the team leader to shut down their own team power, if not a direct fine. As an electrician, some things can not be simplified, unless you can have security risks are avoided, in order to achieve automation. But the cost of your transformation is quite scary!
