Prekawzjonijiet tas-Sigurtà
Always disconnect power before installation or maintenance. Installation should be performed by a qualified electrician in accordance with local electrical codes. Do not expose the device to moisture or extreme temperatures. Ensure proper wiring to avoid damage to the unit or connected appliances.
Setup u Installazzjoni
- Immuntar: The TM-919B is designed for DIN rail mounting. Securely attach the timer to a standard 35mm DIN rail within your electrical distribution board.
- Wiring:
- Connect the main power supply (220-240V AC, 50/60Hz) to the input terminals (typically marked L and N or 1 and 2).
- Connect the load (appliance) to the output terminals (typically marked 3, 4, 5 for a changeover switch). Refer to the wiring diagram on the device for precise connections. Ensure the load does not exceed 30A (resistive) or 15A (inductive).
- Qawwa Inizjali: After wiring, restore power. The display should illuminate. The built-in battery will begin charging, which may take a few hours for full capacity.
- Irrisettja: If the display is erratic or you wish to clear all settings, press the "R" (Reset) button using a pointed non-metallic object. This will clear all programs and reset the clock.
Istruzzjonijiet Operattivi
Issettjar tal-Ħin Kurrenti
- Agħfas il- "P" button (Program) once to enter time setting mode.
- Agħfas "D+" biex tissettja l-ġurnata kurrenti tal-ġimgħa.
- Agħfas "H+" biex tissettja s-siegħa kurrenti.
- Agħfas "M+" biex tissettja l-minuta kurrenti.
- Biex taqleb bejn il-format ta' 12-il siegħa (AM/PM) u 24 siegħa, agħfas "P" u "H+" fl-istess ħin.
- Agħfas il- "P" button again to exit time setting and return to normal operation.
Programming ON/OFF Cycles (16 Programs)
It-tajmer jappoġġja sa 16 programm ON/OFF. Kull programm jikkonsisti minn ħin ON u ħin OFF.
- Agħfas il- "P" button repeatedly to cycle through the program settings (1 ON, 1 OFF, 2 ON, 2 OFF, ..., 16 ON, 16 OFF). The display will show "1 ON", "1 OFF", etc.
- When "1 ON" is displayed, use "D+" to select the day(s) of the week for this ON event. Options include individual days, weekdays, weekends, or all days.
- Użu "H+" u "M+" to set the desired ON hour and minute.
- Agħfas "P" again to move to "1 OFF". Set the day(s), hour, and minute for the OFF event using "D+", "H+", u "M+".
- Repeat steps 2-4 for any additional programs (up to 16).
- Wara li tissettja l-programmi mixtieqa kollha, agħfas il-buttuna "P" button until the display shows the current time, or wait for 30 seconds for it to automatically return to normal operation.
Manwal Override
The timer has a manual override function to temporarily change the output state.
- Agħfas il- "MANUAL" button (or a button labeled with a hand icon, if present) repeatedly to cycle through modes:
- FUQ: L-output huwa kontinwament mixgħul.
- AUTO ON: L-output bħalissa huwa mixgħul, u jsegwi l-programm.
- MITFI: L-output huwa kontinwament MITFI.
- AUTO OFF: L-output bħalissa huwa MITFI, u jsegwi l-programm.
- Select "AUTO ON" or "AUTO OFF" to ensure the timer follows the programmed schedule.
Manutenzjoni
The SINOTIMER TM-919B is designed for low maintenance. Keep the device clean and free from dust. Do not use abrasive cleaners. The built-in rechargeable battery is designed for long life and typically does not require replacement under normal operating conditions. If the display frequently goes blank during power outages, the battery may need servicing by a qualified technician.
