4.1 Viunganisho vya Wiring

Refer to Figure 1 for the physical layout of the terminals.

Power Supply (L-N 230V~): Connect the main 230V AC power supply to the 'L' and 'N' terminals at the bottom of the device.
Pato la Mzigo: Connect the lighting load to the output terminals (typically marked with a lamp symbol or 'L' out).
Control Inputs (A1-A2 8-230V~): These terminals are for connecting external switches or push-buttons to control the dimmer. The control voltage can range from 8V to 230V AC.
Aina za Mzigo: Ensure the dimmer is correctly configured for the connected load type. The device supports ohmic (R), inductive (L), and electronic (C) loads. For energy-saving lamps, utilize the dedicated ESL mode.

4.2 Usanidi wa Awali

After wiring, ensure the power is restored. The device may require initial adjustment of the dimming range and speed using the rotary dials on the front panel.

5. Maagizo ya Uendeshaji

The EUD12NPN-UC dimmer offers various operational modes and adjustable parameters via its front panel controls.

5.1 Operesheni ya Msingi

Kuwasha / Kuzima: Use the connected external switch or push-button. The soft start/stop feature will engage automatically.
Kupunguza: For continuous dimming, use a permanent control signal from a push-button.

5.2 Control Dials (Refer to Figure 1)

Dimming Range (% min/max): Adjusts the minimum and maximum brightness levels.
Dimming Speed (1-5): Controls the rate at which the light brightens or dims during soft start/stop and dimming operations.
Mode Selector (EC, AUTO, LC, ESL, OFF, ON):
- EC: Electronic Control mode.
- Otomatiki: Automatic detection of load type.
- LC: Inductive Load Control mode.
- ESL: Optimized mode for energy-saving lamps.
- BONYEZA: Turns the dimmer off.
- Washa: Turns the dimmer on to full brightness (if not dimmed).

5.3 Kazi Maalum

Kazi ya Usingizi: Gradually decreases lighting until it switches off completely. This function is activated via the control input.
Child Room Function: Gradually increases lighting to a pre-set brightness level. This function is activated via the control input. Note that direct connection in a child's room might not be possible depending on specific wiring configurations.

8. Utatuzi wa shida

If the dimmer is not functioning as expected, consider the following:

Hakuna Pato la Mwanga:
- Check the main power supply to the dimmer.
- Thibitisha miunganisho yote ya waya ni salama na sahihi.
- Ensure the load type selector is set appropriately (EC, AUTO, LC, ESL).
- Confirm the connected lamps are functional and compatible with dimming.
- Check if the dimmer is in 'OFF' mode.
Flickering or Unstable Dimming:
- Ensure the load type selector is correctly set for the connected lamps.
- Adjust the minimum dimming level. Some lamps may flicker at very low brightness.
- Verify the total load does not exceed 500 W.
- For energy-saving lamps, ensure ESL mode is selected.
