DALI Group Selection (for HED3075-A only)
DALI group configuration can be done via software setting from PC or by hardware setting of the rotary switch on the driver.
1. PC grouping can overwrite the rotary switch grouping and vice versa. The latest setting is always applied.
2. There are 16 channels available on the rotary switch. "0" means ungrouped. The rotary switch channel corresponds to the groups listed below:
| Switch Channel | DALI Group | Switch Channel | DALI Group |
|---|---|---|---|
| 0 | ungrouped | 8 | group 7 |
| 1 | group 0 | 9 | group 8 |
| 2 | group 1 | A | group 9 |

Dimming Characteristics
DALI Dimming Curve
The DALI dimming curve illustrates the relationship between the digital light value (0-250) and the light output percentage (0-100%). The curve shows a non-linear response, with light output increasing more sharply at higher digital values.
Switch-Dim Dimming Curve
The Switch-Dim dimming curve shows light output percentage over time (seconds) for actions triggered by a momentary switch. A short press toggles light on/off. A long press initiates a dimming sequence (down to minimum, then up to 50% brightness).
Note: We recommend the number of drivers connected to a switch does not exceed 25 pieces. The maximum length of the wires from push to driver should be no more than 20 meters.
1-10V Dimming Curve
The 1-10V dimming curve shows a linear relationship between control voltage (0V to 10V) and light output percentage (0% to 100%).
Dimming Interface Operation Notes
DALI
These products are supplied as DALI default group 0 and are 'plug n'play DALI' or 'independent DALI' system ready. They are also fully DALI addressable and can be assigned to groups using a DALI programming tool, within the limits specified by the DALI protocol or supporting DALI controllers.
Switch-Dim
The Switch-Dim interface allows simple dimming using commercially available non-latching (momentary) wall switches. Up to 64 LED drivers can be connected to one switch. The Switch-Dim interface can also serve as a manual override for DALI systems.
- Switch Action: Short press (<0.4 second) - Response: Toggle light on / off. (Note: short press must be longer than 0.1s to be valid).
- Switch Action: Long press (>0.4 second) - Response: Toggle dim light / increase brightness.
- Synchronization Switch Action: Long press (>15 seconds) - Response: All lights will dim down to minimum then return to 50% brightness.
1-10V
The 1-10V input is operable via commercially available simple rotary wall switches designed for 1-10V dimming equipment or from dedicated system central dimming controllers.
Note: If the LED driver is used with Switch-Dim or DALI interface before the 1-10V interface, the 1-10V interface may need to be re-set. This is achieved by placing a short circuit across the 1-10V terminals until the light returns to full brightness (approx. 3-5 seconds).
