3. Safety Information

• Installation and maintenance should only be performed by a qualified electrician.
• Ensure the power supply is disconnected before any installation or wiring work.
• Do not exceed the maximum load ratings specified for the device.
• This device is designed for indoor use in dry environments. Avoid exposure to moisture or extreme temperatures.
• Verify all connections are secure to prevent electrical hazards.

4. Setup and Installation

4.1 Mounting

The Kanlux JVT3 16 AS is designed for DIN rail mounting. Securely attach the device to a standard DIN rail within an appropriate electrical enclosure.

4.2 Wiring

Refer to the wiring diagram on the side of the device (Figure 2.3) and the following instructions:

• Connect the Live (L) and Neutral (N) power supply wires to the corresponding input terminals (typically labeled 1 and 2).
• Connect the load (e.g., light fixture, appliance) to the output terminals. The common terminal is usually 3, with normally open (NO) and normally closed (NC) contacts labeled 4 and 5 respectively. Consult the specific diagram on your device for exact terminal assignments.
• Ensure all connections are tight and correctly insulated.

4.3 Initial Power-Up and Time Setting

1. After wiring, restore power to the circuit. The display should illuminate.
2. If the display is blank, check power connections.
3. Press the RESET button (small recessed button) using a pointed object (e.g., pen tip) to clear any previous settings and initialize the device.
4. Set the current time and day:
   • Press the P button repeatedly to cycle through day settings (e.g., MO, TU, WE...).
   • Use the H+ button to set the hour.
   • Use the M+ button to set the minute.

5. Operating Instructions

5.1 Programming ON/OFF Cycles

The timer allows for multiple ON/OFF programs. Follow these steps to set a program:

1. Press the P button once to enter program setting mode. The display will show "1 ON".
2. Use the D+ button to select the day(s) for this program (e.g., individual days, weekdays, weekends, all days).
3. Use the H+ button to set the desired ON hour.
4. Use the M+ button to set the desired ON minute.
5. Press P again. The display will show "1 OFF".
6. Repeat steps 2-4 to set the desired OFF time for the first program.
7. Continue pressing P to set additional ON/OFF programs (e.g., "2 ON", "2 OFF", etc.).
8. To exit program setting mode and return to the current time display, press the MANUAL button.

5.2 Manual Override

The MANUAL button allows you to override the programmed settings temporarily or permanently:

• Press MANUAL repeatedly to cycle through modes:
  • AUTO ON: The timer is currently ON and will follow the next programmed OFF event.
  • AUTO OFF: The timer is currently OFF and will follow the next programmed ON event.
  • ON: The timer is forced ON, ignoring all programs.
  • OFF: The timer is forced OFF, ignoring all programs.
• Select AUTO ON or AUTO OFF to resume automatic operation based on your programs.

5.3 Astronomical Function

The JVT3 16 AS includes an astronomical function, which can automatically adjust ON/OFF times based on sunrise and sunset times for your geographical location. Refer to the device's specific programming menu for setting up the astronomical function, which typically involves inputting your latitude and longitude or selecting a predefined region. This feature allows for energy-efficient control of lighting or other applications.

6. Maintenance

• Cleaning: Wipe the device with a soft, dry cloth. Do not use abrasive cleaners or solvents.
• Battery: The device typically contains an internal battery to maintain settings during power outages. This battery is usually non-replaceable by the user and has a long lifespan. If the display frequently resets or loses time during power interruptions, the internal battery may need servicing by a qualified technician.
• Inspection: Periodically check wiring connections for tightness and signs of wear.

7. Troubleshooting

• Device not powering on:
  • Check the main power supply to the circuit.
  • Verify that the Live (L) and Neutral (N) wires are correctly connected to the input terminals.
• Load not switching ON/OFF as programmed:
  • Ensure the device is in "AUTO ON" or "AUTO OFF" mode (not forced ON/OFF).
  • Review your programmed ON/OFF times for accuracy.
  • Check the current time and day setting on the timer.
  • Verify the load wiring (terminals 3, 4, 5) is correct and secure.
  • Confirm the load is not exceeding the maximum current rating of the timer.
• Display is blank or flickering:
  • Check power supply.
  • If power is stable, the internal battery may be low or faulty. Contact a qualified technician.
