You can use the 4AO module for dimming using an external third-party LED driver/LED dimmer module.
0-10 V
This is the default option where 0V = 0% = off, 10V = 100% = on
- Open Service Settings of the analog output device
- Open the Device tab.
- Default setting is:
| ← AO Dimmer | |
|---|---|
| Min value | 0V |
| Max value | 10V |
| Use other value when output is turned off | ✗ |
| Off value | 0V |
0/1 V - 10 V
Some dimmers require 0V when the light is off, and to start dimming, they use the range 1V - 10V.
- Open Service Settings of the analog output device
- Open the Device tab.
- Change the setting according to the following table:
| ← AO Dimmer | |
|---|---|
| Min value | 1V |
| Max value | 10V |
| Use other value when output is turned off | ✓ |
| Off value | 0V |
Combining Analog Output with Relay (Optional)
If you want to save energy, you may want to turn off the power supply when all lights powered by it are set to 0%. This way, more energy is saved when lights are off.
To extend the power supply’s lifespan, you should use a Smart Rule to turn off the power after all lights have been off for a certain period:
- Open the switch that controls the power supply
- Add a Smart Rule: Equation
| ← Equation | |
|---|---|
| Variables Dimmer 1 Dimmer 2 Light 24 V | Le = 0.20 Le1 = 0 St = 1 (On) |
| Equation (Le = 0) AND (Le1 = 0) AND NOT St alternative: (Le = 0) AND (Le1 = 0) AND (St = 0) | |
| Actions If result is TRUE, perform following actions: Power Supply | Off |
| If result is FALSE, perform following actions: Power Supply | On |
| Duration When to stop executing specified actions Minimum duration Value: 5 minutes Maximum duration Value: No action | True False |
