Automatic clock calibration function
In the unlocked state, first press and hold the “Cancel/Resume” button, and at the same time press the “Clock” button to display “7d=00” to enter the automatic clock calibration function, indicating that the time that needs to be adjusted in one week is seconds. “7d=- xx” means automatic decrease, and “7d=xx” means automatic increase, with a maximum adjustment range of 28 seconds. Press the ‘School Week’ button to adjust the time required for each week, and press the ‘Clock’ button to return. After the setting is completed, it will automatically increase or decrease the time at 00:31:30 every Saturday.
Precautions for operation
To prevent contact heating under high current, it is necessary to tighten the screws on the terminal when wiring.
It is strictly prohibited to install or disassemble products with electricity.
Please replace the battery regularly to avoid insufficient battery power, which may cause unclear or no display. (The time control switch uses battery No. 7)
For equipment that may cause significant economic losses or personal safety, it is important to design with sufficient margin for technical characteristics and performance values, and safety measures such as dual circuit protection should be adopted
Common faults and troubleshooting methods
1. LCD has no display or unclear display, please replace the battery.
2. After power on, if the time control switch is not working properly, check whether the time period setting of the time control switch meets the required requirements, and whether the setting of the week is set to the “automatic” position.
3. The time control switch outputs the indicator light when it reaches the set time, but the relay does not switch. Check if the power supply voltage is too low.
4. Burn out the product
Check if the power supply exceeds the rated power voltage of the product and if the power cord is connected incorrectly.
5. Troubleshooting
When the product malfunctions, first disconnect the power supply, connect the wires correctly according to the wiring diagram, check the circuit for errors, and then follow the operating precautions. If it is indeed a quality issue with the product itself, please contact the local distribution company or our company.
