6.2 Wiring Connections

Refer to the wiring diagram below for correct electrical connections. All wiring must comply with local electrical codes.

Figure 5: Wiring Diagram
This diagram shows the terminal layout: L (Live Input), N (Neutral Input), and output terminals 1, 2, 3, 4, 5 for connecting the load. Terminals 1 and 2 are typically for the normally open contact, while 3, 4, 5 represent common, normally closed, and normally open contacts respectively for the internal relay.

• Connect the Live (L) wire from your power supply to the terminal marked 'L'.
• Connect the Neutral (N) wire from your power supply to the terminal marked 'N'.
• For the load connection, use terminals 3, 4, and 5. Terminal 3 is the common contact. Terminal 4 is normally closed (NC) and Terminal 5 is normally open (NO). Connect your appliance's live wire to Terminal 5 (for switching ON) and the neutral to the neutral supply.
• Ensure all terminal screws are tightened securely.

9. Maintenance

9.1 Cleaning

To clean the timer, wipe it with a soft, dry cloth. Do not use abrasive cleaners or solvents. Ensure no liquids enter the device.

The timer includes an internal NiMH 1.2V rechargeable battery to maintain time and program settings during power outages. This battery is designed for long-term use and typically does not require replacement. If the display is blank or settings are lost frequently after power interruptions, the battery may need professional servicing.

10. Troubleshooting

• Display is blank:
  Check power supply to the timer. Ensure the main power is ON. If power is present and the display remains blank, the internal backup battery might be fully discharged or faulty. Allow the timer to charge for several hours with power connected. If the issue persists, contact support.
• Programs are not running:
  Ensure the timer is in 'AUTO' mode (check the MANUAL button setting). Verify that the current time and day are set correctly. Double-check your program settings for accuracy (ON/OFF times and selected weekdays).
• Time is incorrect:
  Reset the timer using the 'R' button and then re-set the current time and day. Check if Daylight Saving Time (DST) is incorrectly activated/deactivated.
• Appliance does not switch ON/OFF:
  Verify the wiring connections are correct and secure (refer to Section 6.2). Ensure the appliance itself is functional and properly connected. Check the timer's operating mode (AUTO, ON, OFF).
