Instructions for Use
1.Set the delay value in advance before powering on.
2.After setting is completed, the protective cover should be installed to avoid accidental contact with the DIP switch, which may cause malfunction.
3.When driving high currents, it should be used in conjunction with an AC contactor.
4.Reset function: At any moment, if terminals ① and ③ are connected, the contacts will return to the initial position. After disconnection, timing will start from zero. By connecting terminals ① and ③ to an external control contact, a power-off delay can be achieved (Note: DH48S-2Z does not have this function).
5.Pause function and use as an accumulating timer (Note: DH48S-2Z does not have this function): At any moment, if terminal ④ is connected, timing will pause and the display will hold. After disconnection, timing will resume. This function can be used as an accumulating timer.
6.Use shielded wires for reset and pause connections.
7.Do not apply external voltage to the pause and reset terminals.
8.This product should be used in environments free of corrosive gases, dust, direct sunlight, rain, freezing conditions, and oil vapor.
