The side of the module has product information printed on it, including 'DINUY IH.BIM.T' and electrical specifications. Connection terminals are visible on the bottom right.
4. Setup and Installation
Follow these steps for proper installation:
- Power Disconnection: Before starting any work, ensure the main power supply to the circuit where the timer will be installed is completely disconnected. Use a voltage tester to confirm.
- Mounting: The Dinuy Bimo T is designed for DIN rail mounting. Snap the device onto the DIN rail securely within your electrical panel or enclosure.
- Wiring: Connect the timer switch according to the wiring diagram provided on the device or in the product packaging. Typically, this involves connecting the phase (L), neutral (N), and the load wires to the designated terminals.
- Input Power: Connect the incoming phase and neutral to the timer's input terminals.
- Load Connection: Connect the load (e.g., light, fan) to the timer's output terminals.
- Secure Connections: Ensure all wire connections are tight and secure to prevent loose contacts and potential hazards.
- Power Restoration: Once wiring is complete and verified, restore power to the circuit.
5. Operating Instructions
To set and operate your Dinuy Bimo T timer switch:
- Set Current Time: Rotate the 24-hour dial clockwise until the current time aligns with the small arrow or indicator mark on the timer's face. The dial is marked in hours (e.g., 0, 2, 4, ..., 22).
- Program ON/OFF Periods: The dial has small segments (pins) around its circumference. Each segment typically represents a specific time interval (e.g., 15 minutes).
- To set an ON period, push the corresponding segments outwards.
- To set an OFF period, leave the corresponding segments pushed inwards.
Example: To turn a device ON from 6:00 AM to 8:00 AM, push out the segments corresponding to that time range.
- Manual Override: The timer typically has a manual override switch (often a small lever or button).
- Position 'I' or 'ON': Keeps the circuit permanently ON, overriding the program.
- Position 'O' or 'OFF': Keeps the circuit permanently OFF, overriding the program.
- Clock Symbol: Returns control to the programmed schedule.
Always ensure the manual override is set to the clock symbol for automatic operation.
- Operation: Once programmed, the timer will automatically switch the connected device ON and OFF according to the set schedule. The dial will continuously rotate, indicating the current time.
6. Maintenance
The Dinuy Bimo T timer switch requires minimal maintenance. Follow these guidelines:
- Cleaning: Disconnect power before cleaning. Use a soft, dry cloth to wipe the exterior of the device. Do not use abrasive cleaners, solvents, or liquids.
- Inspection: Periodically inspect the device for any signs of damage, loose connections, or overheating. If any issues are found, disconnect power and consult a qualified electrician.
- Environment: Ensure the operating environment remains within the specified temperature and humidity ranges to prolong the device's lifespan.
