Built-in battery saves program memory during power outages.
: Electrical wiring must be handled with care. Always isolate incoming primary circuit breakers prior to interacting with bare wire lines.
You can find the raw PDF manual on most industrial supply websites (Amazon product pages often host the PDF under "Product Guides"). However, because many user guides are poorly translated, the following sections clarify the most confusing parts. sinotimer tm-630s manual
Pressing this button switches the operating mode between , AUTO , and OFF .
is a microcomputer-controlled digital time switch engineered to automate high-current industrial, commercial, and residential electronic circuits . Boasting a robust and unique down-to-the-second precision , this 24/7 programmable timer eliminates the need for expensive external relays or contactors when managing heavy electrical loads.

Press to choose the days of the week (e.g., Daily, Weekdays, or Weekends). Press H+ , M+ , and S+ (Second) to set the exact start time.
Wiring is critical. Incorrect wiring can damage the device or cause a short circuit. The timer uses a "1NO + 1NC" configuration, meaning it has one circuit that is normally open (disconnected when idle) and one that is normally closed (connected when idle). You can find the raw PDF manual on
A common issue is a blank or frozen display. This often happens if the internal rechargeable battery has been fully drained after a long period without main power. In many cases, simply plugging the timer into a powered socket for several hours will recharge the battery and restore normal operation.
12V DC, 24V DC, 110V AC, or 220V AC (Verify the specific model printed on your device casing). Switching Capacity: 30A resistive load, 20A inductive load. Power Consumption: < 2W. Time Control Range: 1 second to 168 hours. Program Memory: 28 On/Off programs per day or week.
Regular maintenance is minimal. Periodically check the timer's operation by manually activating it to ensure the relay clicks. Keep the panel clean and dry, and every few months, cycle through your programs to verify they are still accurate. If you notice the time drifting excessively, the internal battery may be reaching the end of its life.
