3.1. Wiring Diagram

Proper wiring is crucial for the safe and correct operation of the TM618 timer module. Refer to the diagram below for connection details. Ensure power is disconnected before performing any wiring.

Figure 3.1: Wiring Terminals and Specifications.

• Input (200-250VAC): Connect your main power supply to terminals 1 and 2.
• Output (16 AMP / 250VAC, 20 AMP @30 VDC): Terminals 3, 4, and 5 are for the controlled output. Terminal 3 is common, Terminal 4 is normally open (NO), and Terminal 5 is normally closed (NC). Connect your load to the appropriate terminals based on your application (e.g., between 3 and 4 for normally off, turning on when timed).

3.2. Initial Power-Up and Battery

Upon initial power-up, the timer's internal rechargeable battery (40mAh) will begin charging. This battery saves your programmed settings during power interruptions. Allow the unit to be powered for at least 30 minutes for the battery to gain sufficient charge before programming or disconnecting power.

4.4. Recall Function

The RECALL button (often marked 'R' or 'RESET') is used to clear specific program settings or to reset the timer. A small pinhole button (R) is typically used for a full reset, which clears all programs and resets the time.

5. Maintenance

5.1. Battery Care

The TM618 features a built-in rechargeable battery. To ensure its longevity and proper function, keep the timer connected to power for regular charging. If the timer is stored for extended periods without power, the battery may discharge, requiring a full charge upon reconnection.

5.2. Cleaning

Clean the exterior of the timer module with a soft, dry cloth. Do not use abrasive cleaners or solvents, as these can damage the plastic casing or display. Ensure no liquids enter the device.

6. Troubleshooting

• Display is blank: Check power connections. Ensure the unit has been powered for at least 30 minutes to charge the internal battery.
• Programs not executing: Verify that the current time is set correctly. Check that the timer is in "AUTO ON" or "AUTO OFF" mode, not forced ON/OFF. Review your programmed ON/OFF times for accuracy.
• Timer not responding to buttons: Perform a full reset using the small 'R' pinhole button. If issues persist, ensure proper power supply.
