Use instruction:
1.Set delay time first, then switch on electric power.
2.After delay time set, should cover the protective hat, to avoid to press the dial switch then timer action.
3. If the load current is big, should be used with contactor.
4. When switch on ①③ terminal, the contact position will reset, when switch off, the time will begin with zero, can use this function to achieve Off‐delay function (DH48S‐2Z don’t have this function).
5. Use pause function as a counter: (DH48S‐2Z don’t have this function), when switch on ①④ terminal, the time is pause, display hold, when switch off, the time continue.
6. Reset and pause wire, please use shield wire.
7. Forbid add voltage to pause or reset terminal.
8. The use circumstance should be without causticity, dust, rain, frost, oil mist.
9. Note: This product can full display, hidden zero, count, countdown.
