Instellen en installeren
- Montage: The TM-919B is designed for DIN rail mounting. Securely attach the timer to a standard 35mm DIN rail within your electrical distribution board.
- Bedrading:
- 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).
- Eerste keer opstarten: After wiring, restore power. The display should illuminate. The built-in battery will begin charging, which may take a few hours for full capacity.
- Reset: 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.
