Q:How to prohibit the computer record switch machine time
Path: c: / windows / SchedLgU ("~ .txt" file) The file from the "Task Sheduler" service control, into the service management, the service off, after the file will no longer record whether you switch machine, Off this service you can delete the file, or delete, but also can not change.
Q:Microcomputer tb-12 timer switch how to adjust the time
* Adjust the clock: Press and hold the [CLOCK] button while pressing [TIME], [DIV], [DAY] button to adjust the clock, week.
Q:Aluminum windows have a long time difficult to switch how to do
1, if it is a flat window, with the oil point of the sash of the hinge of the axis, back and forth switch several times on the line;
Q:How to define the mechanical equipment in advance switch machine time?
Set the automatic shutdown, if you want to cancel, you can run in the input "shutdown-a". Also enter "shutdown-i", you can open the set automatic shutdown dialog box, set the automatic shutdown. Shutdown.exe parameters, each with a specific purpose, the implementation of each will have a different effect, such as "-s" means that the closure of the local computer, "- a" that cancel the shutdown operation, the following list of more parameters , We can use in Shutdown.exe on demand.
Q:During the day automatically power off, night fixed time bright, called what switch?
Timing switch, with the same time as the lights a few lights, a few points off.
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
1. Automatic timing boot This feature needs to be set in the BIOS, and your motherboard's advanced power management settings must support this feature, but now most of the motherboard support, rest assured to use it. step one: Start the system press DEL, enter the BIOS, and then select the "POWER MANAGEMENT FEATURES" (Power management settings), enter in the power window to find "RESTORE ON AC / POWER LOSS "item, press Enter, and then set the value to" POWER ON "with the arrow keys. Step two: Select "RESUME ON RTC ALARM" and press Enter, then use the arrow keys to set its value to "ENABLE" Step three: Select "RTC ALARM DATE" press Enter, and then set its value to "EVERYDAY", that every day the same operation, in accordance with the same method, respectively, "RTC ALARM HOURS" "RTC ALARM MINUTE" "RTM ALARM SECOND "Set to" 07 "" 15 "" 00 ", which means the boot time for the morning" 7:15:00 ", all set up, press F10, save and restart. (Due to the different motherboard BIOS is not the same, some motherboard settings may be a little bit different from the above, but just remember to find in the power management "WAKE UP" words on the line, because this is set the timing boot option)
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
With a time delay to pull the time relay, a normally open button, a contactor to complete the entire circuit. Wiring: 1. Firewire then open the button to the time relay closed point and then press the contactor coil and then to the zero line. 2. Contactor self-locking. Take the normally open ignition line through the contactor and connect to the button and the time relay. 3. Fire line through the contactor normally open point connected to the time relay power L-side, N then zero line. 4. Three-phase electric air open to the receiver and then to the motor Wiring is complete. Press the button (no lock button) contactor pull, self-locking to keep the contactor pull. At the same time the time relay power, began to delay. To set the time, time relay pull, normally closed point off. The contactor coil is de-energized. The motor stops. Until the start button is pressed again, the next job starts.
Q:With two time relay how to achieve 10 seconds repeated switch
A time relay control on, another time relay control off. But each time the relay to be equipped with a small relay Caixing.
Q:Want to use a proximity switch, a time relay, a solenoid valve to control the automatic reciprocating motion of the cylinder.
The solenoid valve controls the reciprocating motion of the cylinder and sends a signal to the solenoid valve through the proximity switch, with the time relay being used.
Q:For example, I use the IGBT circuit switch, using the same gate resistance and drive circuit. Then use it to make a normal working current only 1A off the external circuit off time And let a current up to 100A of the external circuit completely off the turn-off time, Will there be a big difference between the two times? Or that depends entirely on the drive part of the control of the gate G, CE voltage at both ends of the voltage is not much relationship?
If both IGBTs are able to operate under these two currents, there is a difference in turn-off time. When the shutdown signal is issued, due to the circuit can not avoid the role of inductance, the current will not immediately drop to 0, need to wait until the accumulation of the cathode in the CE gradually disappeared, in order to completely shut down. The greater the current, the more carriers that flow through, and the more the stacking, the longer the natural shutoff time. Although there are differences, but such as IGBT power electronic devices, the difference is between several tens to two hundred milliseconds. I do not know this time for you is long and short.
