How to set the timer time of electric fan? What should I pay attention to when using a timer?

We all choose the right time when using electric fans, especially at night. If we blow the electric fan for a long time, we will catch a cold and even get a stiff neck. Usually after a period of time, the ceiling fan is turned off. Timers are popular now, which can control the time and is convenient to use. So how to set the timer time of the electric fan? What should I pay attention to when using a timer? We all choose the right time when using electric fans, especially at night. If we blow the electric fan for a long time, we will catch a cold and even get a stiff neck. Usually after a period of time, the ceiling fan is turned off. Timers are popular now, which can control the time and is convenient to use. So let me introduce the time setting method of electric fan timer? What should I pay attention to when using a timer?

How to set the timer time of electric fan?

1. At present, the time adjustment mode of electronic timer is relatively simple, and it needs to be combined with key operation (Note: by default, the three keys of week, hour and minute are shielded, and there is no response after being pressed alone. You need to press the clock key first, and then press any key of week, hour and minute, which is also a way to prevent accidental misoperation, so all three keys are shielded).

2. Adjust the week: press the clock key first, and then press the week key to adjust to the current week value. (Every time you press 1 time, it will increase 1 day. Long press can be quickly adjusted. ) Adjust the hour: press the clock key first, then press the hour key to adjust to the current hour value. (Every time you press 1 time, you will increase 1 hour. Long press can be quickly adjusted. ) Adjust score: press the clock key first, and then press the subkey to adjust to the current score. (Every time you press 1 time, you get 1 point. Long press can be quickly adjusted. )

3. Adjust daylight saving time: the timer has its own daylight saving time function, which can be selected and is not turned on by default. Operation method: press and hold the clock key for 3 seconds, the current time increases by 1 hour, and the LCD screen displays? Daylight saving time? Words, enter the daylight saving time function; Press the clock button for 3 seconds, the current time will be reduced by 1 hour, and the LCD screen will be cancelled? Daylight saving time? Words, exit the daylight saving time function.

What should I pay attention to when using a timer?

1. If timers such as T0 and T 1 are used in FC, there will be problems if they are called many times. A timer cannot be used for two devices at the same time! The solution is to create an input parameter with the parameter type Timer in FC, and specify different arguments for this parameter when calling, such as T0 for device A, T 1 for device B, and so on. The essence of structured programming and its comparison with other PLCs (including S7-200) lies in the portability and reusability of FB and FC. Its basic rule is that FB and FC do not use global variables, but all use local variables.

2. The internal programs of 2.FB and FC can be called many times in the same project or transplanted to other projects without any modification. Many parameter types of FC and FB can meet this requirement. Programmers who have accumulated a lot of FC and FB in their work can quickly create similar system programs that meet the requirements of different customers like building blocks. Programmers should get into the habit of not using global variables inside FB and FC!

How to set the timer time of electric fan through personal introduction? What should I pay attention to when using a timer? Every brand has a different way to use the timer, so before setting it, we can look at how it is written in the manual and then operate it step by step. Or we can consult a professional when buying.
