RA3 Blink Codes for Sunnata Devices

 

Sunnata Devices 
 

NOTE: Indicator lights are numerically ordered from bottom to top.   

Example: Indicator light "1" is the bottom LED, indicator light "9" is the top LED.

 

Symptom: 

  • Main dimmer: LEDs 6, 8, and 9 are flashing slowly (once per second). 
  • Some companions: LEDs 1, 2, and 4 are flashing quickly (three times per second). 
  • Other companions: LEDs 7, 8, and 9 are flashing slowly (once per second) or no LEDs are illuminated. 

Sunnata dimmer with LEDs 6, 8, and 9 flashing slowly (once per second)

Cause: 

  1. One or more companion dimmers are on the load side of the main dimmer. Main dimmer must be on the load side of the circuit.

Action:  

  1. Swap the main dimmer with a companion dimmer that has LEDs 1, 2, and 4 flashing quickly (three times per second).   

 



Symptom: 

  • Main dimmer: LEDs 1,7, and 9 are flashing. 
  • Companion: No LEDs illuminated.

Cause: 

  1. Wiring error. 

Action:

  1. Swap wires on blue and brass terminals on the main dimmer.   
  2. Ensure wiring matches wiring diagrams.  

 



Symptom: 

  • Main dimmer: LEDs 7, 8, and 9 are flashing. 
  • Companion: No LEDs illuminated. 

Sunnata dimmer with LEDs 7, 8, and 9 flashing

Cause: 

  1. Wiring error. 

Action:

  1. Swap wires on blue and brass terminals on the main dimmer.   
  2. Ensure wiring matches wiring diagrams.  

 



Symptom: 

  • Main dimmer: LEDs 1 and 7 are flashing.
  • Companion: No LEDs illuminated.

Sunnata dimmer with LEDs 1 and 7 flashing

Cause: 

  1. Improper phase selection.
  2. Incoming line voltage is too high.

Action:

  1. Change to forward-phase. Confirm load compatibility in Step 2 and use instructions in Step 7 / Phase-Select Mode to change phase.  
  2. Ensure that the input voltage to the device is less than 130 V~.  

 



Symptom: 

  • Main dimmer: LEDs 1, 2, and 3 are flashing. 
  • Companion: No LEDs illuminated. 

Sunnata dimmer with LEDs 1, 2, and 3  flashing

Cause: 

  1. Incompatible load. 
  2. Hot and neutral connections are reversed. 

Action:

  1. Check if lamp is compatible on www.lutron.com/ledfinder. Change to a compatible lamp. 
  2. Swap wires on the black and silver terminals.  

 



Symptom: 

  • Main dimmer: LED 5 is flashing.
  • Companion: No LEDs illuminated.

Sunnata dimmer with LED 5 flashing

Cause: 

  1. Load or ambient temperature exceeds ratings.

Action:

  1. Ensure load is within ratings. See Step 2 of the installation guide or refer to "Sunnata PRO Dimmers & Switches".
  2. Note deratings for multi-gang applications.
  3. Ensure ambient temperature is less than 104 °F ( 40 °C). 
  4. Pull FASS and replace. See Step 6 of the installation guide.  

 



Symptom: 

  • Main dimmer: LEDs 1-9 are flashing.
  • Companion: No LEDs illuminated.

Sunnata dimmer with LEDs 1-9 flashing

Cause: 

  1. Wiring issue at main dimmer.
  2. Wiring issue at load or load failure.
  3. Improper phase selection.
  4. Incompatible load.

Action:

  1. Swap wires on the silver and brass terminals on the main dimmer.   
  2. Check wiring at all the terminals.   
  3. Check for short circuits to neutral or ground in all wiring locations, including at the load.   
  4. Remove load and check if it failed as a short.   
  5. Change phase. Confirm load compatibility in Step 2 and use instructions in Step 7 / Phase-Select Mode to change phase.   
  6. Check if lamp is compatible on www.lutron.com/ledfinder. Change to compatible lamp.

 


 

 

Standard Sunnata Keypads  


 

Symptom: 

  • Status LEDs on the keypad don’t light up when buttons on it are pressed.

 

Cause: 

  1. Power is not present at the keypad.  
  2. Incorrect wiring.

Action:  

  1. Circuit breaker OFF. Turn ON breaker. 
  2. Wire the keypad according to the installation section.  
     

 

Symptom: 

  • All status LEDs on the keypad flash when any button is pressed. 

 

Cause: 

  1. The keypad is in the Factory Settings Mode and has not been configured to work in a system. 

 Action

  1. Refer to the RadioRa3 programming software and ensure that the device is assigned to that keypad. Perform a transfer and make sure it is successful.  

 


Hybrid Sunnata Keypads  


 

Symptom: 

  • Top LED blinks once per second and bottom LED is off (or dimly lit).

 

Cause: 

  1. Hybrid keypad is detecting a wiring error.  

Action

  1. Check the wiring against Step 3 of the instructions. Verify that the black and red wires are not swapped.  

 



Symptom: 

  • Top and Bottom LEDs flashing alternatively, once per second.  

 

Cause: 

  1. Hybrid keypad is seeing higher voltage than expected.  

Action:

  1. Change between forward-phase and reverse-phase. Refer to Step 7 "Phase-Select Mode" of the installation guide.  
  2. Ensure that the input voltage to the device is less than 130V~.

 



Symptom: 

  • One LED flashes once per second, another stays on. 

 

Cause: 

  1. Hybrid keypad is detecting a problem with the circuit.  

Action:

  1. Verify that the bulb is dimmable. Test with an incandescent/halogen bulb. Check compatibility on www.lutron.com/ledfinder.
  2. Check the wiring against Step 3 of the instructions. Verify that the black and white wires are not swapped.  
  3. Test on another lighting circuit.  

 



Symptom: 

  • Top and Bottom LEDs flashing together, once per second.  

 

Cause: 

  1. Hybrid keypad has exceeded its rated temperature.  

Action:

  1. Ensure load is within ratings noted in Step 2 of the install guide. Note derating for multi-gang applications.   
  2. Ensure ambient temperature is less than 104°F (40°C).

 



Symptom: 

  • Top LED stays on, bottom LED blinks once a second.  

 

Cause: 

  1. Hybrid keypad is seeing higher current than expected.  

Action:

  1. Check the wiring against Step 3 of the instructions. Verify that the white and red wires are not swapped.  
  2. Check the short circuits to neutral and ground in all wiring locations, including at the load.  
  3. Replace the load(s) to check if it failed as a short.  
  4. Change between forward-phase and reverse-phase. Refer to the instructions under Setup for phase selection.  
  5. Check if bulb is compatible on www.lutron.com/ledfinder. Change to compatible bulb.
