While enhancing your brilliance, it also saves you expenses reasonably. 5. Used for regular irrigation of gardens, regular drainage, and aquarium breeding. 6. It is used for monitoring video timing switch, school timing broadcast broadcast, etc. various uses. The product can be set to 17 groups per day, namely: 17 times of on and 17 times of off, direct control wiring, the controlled electrical appliances need to be single-phase power supply (220V), power consumption rated capacity (resistive load 16A, inductive load 8A)
Wiring diagram description: 1. The "switch" is a switch that is not connected to the "power" with "current" and only controls a live wire. 2. The timer has no voltage transformation function, and cannot input AC220V and output DC12V. The timer has only input (supply voltage) and no output. It is not a common type of two-in and two-out timers. The new wiring method can control non-current lines such as telephone lines. 3. It can control the voltage different from the "power supply", such as AC220V power supply, but control the on and off of one of the lines of the external power supply DC12V line. 4. The switch is off when it is not working, and current cannot pass through.
2. Timing setting
A. Press the "timing" button, the bottom left of the display shows the word "1 ON" (indicating the first turn-on time). Then press the "minute", "??" and "week" keys respectively to enter the required opening time.
B. After pressing the "timing" button, the word "1 OFF" is displayed at the bottom left of the display screen (indicating the time of first closing). Then press the "minute", "hour" and "week" keys respectively to enter the desired closing time.
C. Continue to press the "timing" key, the lower left of the screen will display (2 ON, 2 OFF…17 ON, 17 OFF) in turn, refer to steps A and B to set the switching time for each subsequent time. If you only need to set on and off once, you must press the "Cancel/Resume" button to cancel the time set later.
D. Press the "Set" button, and then press the "Week" button to set the same day, different day, the same from Monday to Friday, Monday to Saturday, or the same different cycle from Saturday to Sunday.
Troubleshooting:
1. If the switch is not turned on when the switch is set to on, or the time to turn off is not turned off after it is turned on, check whether the "week" is correct, otherwise please re-adjust.
2. If it is confirmed that the "on" and "off" times are adjusted completely correctly, but the switch is turned on at a time when it should not be turned on, or turned off at a time when it should not be turned off, please check whether the excess switching time is eliminated. No, please refer to the method introduced in "Time Setting" to eliminate (note: the switch time display "--:--" means elimination, don't think "00:00" means elimination)
3. If all the above two items are correct, but the switch still does not operate normally, please check whether it is in the automatic position.
Precautions:
1. In order to prevent electric shock and heat generation under strong current, the product is used in electrical appliances and the power supply is firmly in contact.
2. The incoming line of this switch can only be connected to the specified voltage power supply, not to other power sources. The damage of wrong wiring is not a quality problem (for special voltage specifications, please order).
3. For those equipment (such as medical equipment and large equipment, etc.) that may have life-related accidents or have a major impact on society due to the time control switch error, please do not use this control switch.
4. This switch should work in an environment free from humidity, corrosion and heavy metal content. Do not contaminate it with oil or water.
