4. Opsætning og installation
4.1 Montering
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 Ledningsføring
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.
- Sørg for, at alle forbindelser er tætte og korrekt isolerede.
4.3 Initial Power-Up and Time Setting
- After wiring, restore power to the circuit. The display should illuminate.
- If the display is blank, check power connections.
- Tryk på NULSTIL button (small recessed button) using a pointed object (e.g., pen tip) to clear any previous settings and initialize the device.
- Set the current time and day:
- Tryk på P button repeatedly to cycle through day settings (e.g., MO, TU, WE...).
- Brug H+ knappen for at indstille timen.
- Brug M+ knappen for at indstille minutter.
5. Betjeningsvejledning
5.1 Programming ON/OFF Cycles
The timer allows for multiple ON/OFF programs. Follow these steps to set a program:
- Tryk på P button once to enter program setting mode. The display will show "1 ON".
- Brug D+ button to select the day(s) for this program (e.g., individual days, weekdays, weekends, all days).
- Brug H+ -knappen for at indstille den ønskede ON-time.
- Brug M+ -knappen for at indstille det ønskede ON-minut.
- Trykke P igen. Displayet vil vise "1 OFF".
- Gentag trin 2-4 for at indstille den ønskede SLUKNINGstid for det første program.
- Fortsæt med at trykke P to set additional ON/OFF programs (e.g., "2 ON", "2 OFF", etc.).
- To exit program setting mode and return to the current time display, press the MANUEL knap.
5.2 Manuel tilsidesættelse
De MANUEL button allows you to override the programmed settings temporarily or permanently:
- Trykke MANUEL gentagne gange for at skifte mellem tilstande:
- AUTO TIL: 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.
- PÅ: The timer is forced ON, ignoring all programs.
- OFF: The timer is forced OFF, ignoring all programs.
- Vælge AUTO TIL or AUTO FRA 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. Vedligeholdelse
- Rensning: Tør enheden af med en blød, tør klud. Brug ikke slibende rengøringsmidler eller opløsningsmidler.
- Batteri: 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.
- Inspektion: Kontroller regelmæssigt ledningsforbindelserne for tæthed og tegn på slid.
7. Fejlfinding
- Enheden tænder ikke:
- 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.
- Skærmen er tom eller flimrer:
- Tjek strømforsyningen.
- If power is stable, the internal battery may be low or faulty. Contact a qualified technician.
