7個步驟解決時控開關的故障問題
注意：當產品出現故障後，請先斷開電源，再進行設備檢查！
1 請檢查「星期」是否正確
如果時控開關沒有在設定的時間開啟或關閉負載，那可能是「星期」沒調對，請按照「定時設置」中介紹的方法檢查或重調。
2 請檢查多餘的時間組是否取消
如果第一點確認無誤，卻依舊出現不能按時開關負載的情況，那可能是因為沒有取消多餘的時間組，請參照「定時設置」中介紹的方法進行刪除。注意：只有顯示為「-- : --」才表示取消成功; 如果顯示「00：00」則表示0點（24點），並非取消成功。
3 請檢查時控開關是否工作在自動模式
如果上述兩點確認無誤，而時控開關仍無法正常工作，那有可能是時控開關處於「手動模式」，可通過調節「自動/手動」鍵將設備先調節到當前所需的工作狀態，然後再調節到「自動模式」。
4 請檢查保險管
如果以上三點確認無誤，可時控開關依舊無法正常工作，請打開後座保險蓋（端子蓋板），檢查保險管是否己經熔斷。如己熔斷，請換上新的0.1A~0.3A的保險管。
5 請檢查供電電源
如果遇到時控開關在工作時，工作燈亮（輸出指示燈），但是開關無法正常切換的情況，請檢查電源電壓是否過低。如果時控開關被燒壞產品，請檢查供電電源是否超出了產品的額定電壓，以及電源線是否接錯。
6 請更換電池
如果LCD液晶屏不顯示或者顯示不清，需更換相同規格的電池。（僅限可更換電池的時控開關）
7 請聯繫我們或當地經銷商
如用以上幾種方法還不能排除故障，請與本公司或者當地經銷商聯繫處理。
7 steps to solve the failure of time control switch (Timer Switch)
Note: When the product fails, please disconnect the power first, and then check the equipment!
1 Check the week:
If the timer switch does not turn on or turn off the load at the set time, it may be that the "WEEK" is not adjusted correctly, please check or reset it according to the method introduced in "Timing Setting".
2 Check the time groups:
If the first point is confirmed to be correct, but the load still cannot be switched correctly on time, the reason will be that the extra time group has not been cancelled. Please refer to the method introduced in "Timing Setting" to delete it. PS: Only when the display shows "--: --", it means the time group is deleted successful; if it displays "00:00", it means 0 o'clock (24 o'clock), not the deleting success.
3 Check the switching mode:
If the above two points are confirmed to be correct, but the timer switch still does not work normally, it may be that the timer switch is working in "Manual Mode". You can first adjust the "AUTO/MANU" key to set the timer switch to the right working state of the load (ON or OFF), then switch to the "Automatic Mode".
4 Check the fuse:
If the above three points are correct and the timer switch still cannot work normally, please open the rear seat insurance cover (terminal cover) and check whether the fuse has been blown. If it is blown, please replace with a new 0.1A~0.3A fuse.
5 Check the power supply:
If the Work LED (or Output LED) is on when the timer switch is working, but the load cannot be switched normally, please check whether the voltage of the power supply is too low. If the timer switch is burned out, please check whether the power supply voltage exceeds the rated voltage of the product and whether the power cable is connected incorrectly.
6 Please replace the battery:
If the LCD screen does not display or the display is not clear, replace the battery with the same specification. (Only for timer switch with replaceable batteries)
7 Please contact us or local distributor:
If the fault cannot be eliminated by the above methods, please contact us or the distributor (dealer) in your local area.
