Instructions:
 
Note: The start button needs to be able to withstand the load current for a short time (about 0.3 seconds), which means that if you control the 5A current fan, the start button should be able to withstand 5A and above for a short time.
 
Time range setting:
When the selector switch is placed in the 30 position, it means 0-30 adjustable
When the selector switch is placed at position 300, it indicates that 0-300 is adjustable.
 
Adjustment of time value:
Adjustable resistance rotates counterclockwise to the direction of the number to reduce the time, clockwise to the + direction to increase the time
 
Time unit setting:
When the selector switch is placed in the Sec position, the unit is: second
When the selector switch is placed in the Min position, the unit is: minute
 
Example:
Request a delay of 50 minutes:
1. The range is placed at 300 position
2. The time unit is placed in the Min position.
3. Adjust the adjustable resistance to 50 position, adjust to 300, so adjust to 1/5 is 50.
Note: The potentiometer adjustment can also be quickly adjusted with the multimeter voltage file. For example, the range is 30, and it needs to be adjusted to 12, then the voltage can be adjusted to 2.
 
t=Ut/5*30=2.0V / 5.0V * 30 =12
 
Ut is the voltage measured by the multimeter, 30 is the range selected by the selector switch, and can also be selected to 300.
