- Q: For example, I hope that at some time the computer is unable to boot, unless there is an administrator password. Or at a certain point in time to shut down, is mandatory. How to operate, or what software to download? Please heroes pointing to help!
- Ah can be specific to the Internet check
- Q: It is best to have pictures, the effect is to achieve this, power, light does not shine, press the button switch, 15 minutes after the light, then press the switch, the lights and then off, do not press the lights immortal. Can not achieve such a procedure. The relay is energized.
- Now the electronic time relay does not perform the normally open contacts, can not complete the LZ requirements, if there is a reset contact can be (button to reset the contact, that is, the relay delay 15 minutes after the lights, when the button when the relay reset Light off, wait until 15 minutes and then bright, that is, a light off for 15 minutes). However, if you use a balloon-type time relay can meet the requirements of LZ, because the relay has two delay contact and two normally open contacts and two normally closed contacts.
- Q: How to give the computer a fixed time switch machine
- Open the Run dialog box shortcut key is WIN + R Enter at 20:50 shutdown-s It is at 20:50 off - s is off, -r is restart Start - run - enter shutdown.exe -s -t 3600 carriage return can be Note 3600 means 3600 seconds = one hour you can also change it to 7200 1800 and the like Set a certain time automatically shut down If you need the computer to automatically shut down at 20:20, then only in the "Start" menu, select "Run", then enter at 20:20 Shutdown-s, click "OK" can be. So when the computer system time to 20:20, the computer will automatically appear "system shutdown" dialog box, 30 seconds later will automatically shut down, this 30 seconds is to allow users to save the current operation before the shutdown, so as not to cause Unnecessary loss. Note: The -s parameter refers to the local computer. Set two countdown auto shutdown If you need the computer to automatically shut down after 10 minutes, then only in the "Start" menu, select "Run", and then enter Shutdown-s-t 600, click "OK" button. So that the computer began to countdown, 10 minutes after the computer will automatically shut down. Note: The -t parameter is the countdown auto-shutdown command, the 600 parameter is 10 minutes or 600 seconds. Set three to cancel automatic shutdown If you have set the automatic shutdown, but changed your mind, do not have to automatically shut down, then only in the "Start" menu, select "Run", and then enter Shutdown-a, click "OK" button. This closes the automatic shutdown that has been set. Note: The -a parameter is a command to cancel the automatic shutdown.
- Q: 1, how can the length of a switch in the PLC to control the length of the output voltage? The longer the input switch closure time, the higher the output voltage, which type of PLC to choose? 2, in the input to a signal, the PLC internal program can control the output voltage from a specific value of a linear transformation to another value? 3, PLC can directly drive the load? The load is a DC solenoid with a power of 30W.
- You can need to add analog expansion module but is a level of voltage changes rather than stepless changes should be used to control the timing is only a very short time interval and the output of the analog signal and then through the amplifier output control voltage on the line because the PLC The rated voltage on the point of the estimated that you can not reach the requirements of the PLC is not directly add the load are generally added to the middle of the relay or the rules do not lose the craft Oh
- Q: How can we set up the morning 6 o'clock in the morning how to set up the computer when the machine automatically boot ah How to set it to automatically shut down? Thank you
- 3. Automatic shutdown If you work very much, often forget to rest at night, or forget to shut down, then this can help you step one: In the "Task Schedule" window, double-click the Add Task Plan, Next, and then click Browse, in the Select Program to Program the window in the C: WINDOWS SYSTEM32 "directory to find the SHUTDOWN.EXE program and click the Open button. Step two: Set the time to execute this task to "Every day", click Next, set the start time to "23:00" and click Next to enter the user name and password as required, and open the task plan when you click Finish The advanced properties are also completed Step three: In the pop-up SHUTDOWN window point "task", and then in the "line" stop type "C: WINDOWS system32 shutdown.exe -s-t 60" (where -S said to turn off the computer, -T 60 for 60 seconds Automatically turn off the computer, the shutdown time can be set according to their own needs) click on the application, and re-enter the user password, the last point to determine! (If you want to cancel the automatic shutdown, in the operation of the input "Shutdown-a" command on the carriage return
- Q: The diode is a switching element, and its switching time includes what and what
- The general reverse recovery time is greater than the opening time, so the use of switching diodes on the parameters only gives the reverse recovery time. Switching diode switching speed is quite fast, like silicon switching diode reverse recovery time only a few nanoseconds, even germanium switching diodes, but also a few hundred nanoseconds.
- Q: I produced the power supply is output 12V and 5V two groups. Current is 2A. Will the normal aging time is how much the load should be connected to the number of normal. Please advise experts. Thank you so here.
- The initial trial production can be 24 hours of aging, and take 10% of which for a long time aging (at least half a month) to ensure quality. Into the first five batches of 100% load aging 40 minutes, if no problem and then you can use 80% or 100% load aging 25-30 minutes. General power plants are the same operation.
- Q: With two time relay how to achieve 10 seconds repeated switch
- You can buy a dual-time relay finished products, it has two time above the knob, you can adjust the "open" and "together" time, power will continue to cycle in accordance with set a good time off.
- Q: The difference between voltage time switch and current time type switch
- Mainly in the switch tube control in different ways, the voltage type of the switch is a field effect transistor (voltage control), the current type of bipolar high-power three-pole (current control).
- Q: How to adjust the time switchlight switch
- [Adjust the clock]: Press and hold the [Clock] button and press [Time], [minutes], [Week] to adjust the clock and week; * There are 15 combinations of weeks on each opening and closing time setting; * Note: If you do not need to set 10 groups, the number of redundant groups with the [Cancel / Resume] button to cancel, display "-: -" that is eliminated, if you press the [Cancel / Resume] button to restore Before the original time set; * Check: Press the [TIMING] button continuously to check the time set for each group, and whether the week is correct;
