Power LED Blink Patterns for Echoflex Controllers

Question

The power LED on my Echoflex Controller is blinking (in some pattern). What does this mean?

Answer

Echoflex controllers use their power LED to indicate link status, including where they are in an active linking process or what and how many devices they are currently linked to.

Blink patterns can vary based on the controller, as not every controller is compatible with the same control devices. See chart below or reference the controller's installation guide.

If the controller is in LEARN mode, the learn LED will also indicate (see bottom chart).

If the controller is linked to multiple types of stations, you will see the blink patterns rotate through each type.

For each linked device type the controller sees linked, the power LED:

  • flashes X number of long blinks indicating the type of linked device (see chart below for what each long blink number means by controller)
  • then flashes X number of short blinks indicating how many devices of that type

Linked Device Type Power LED Long Blink Count

  Solid On 1 Long 2 Long  3 Long  4 Long  5 Long 6 Long  7 Long
ERDRC None Switch Occ/Vac Sensor Photo Sensor Central Command      
ELED1 None Switch Occ/Vac Sensor Photo Sensor Central Command Demand Response    
ELED2 None Switch Occ/Vac Sensor Photo Sensor Central Command Demand Response    
ELED3 None Switch Occ/Vac Sensor Photo Sensor Central Command Demand Response    
ER6CD None Switch Occ/Vac Sensor Photo Sensor Central Command Demand Response    
ER1C None Switch Occ/Vac Sensor Photo Sensor Central Command Keycard Entry Door Trigger Door/Window Switch
ERM None Switch Occ/Vac Sensor Photo Sensor Central Command Keycard Entry Door Trigger Door/Window Switch
ERNR None Switch Occ/Vac Sensor Photo Sensor Central Command Keycard Entry Door Trigger Door/Window Switch

 

Example: if an ELED1 controller is linked to 2 switches and 1 photo sensor, based on the chart below you will see the following repeat consistently:

  • 1 long blink, 2 short blinks (indicates 2 switches linked)
  • 3 long blinks, 1 short blink (indicates 1 photo sensor linked)
  • Repeat

Learn Mode Power and Learn LED Statuses

(these should be the same for all controllers)

Status/Indication Power LED Blink Pattern Learn LED
In link mode (waiting for a 'teach' telegram) Toggle on/off every 2 seconds On solid
Storing transmitter ID (linking to transmitter) On 4 seconds On solid
Clearing transmitter ID (unlinking from transmitter) Off 4 seconds On solid
CLEAR mode (unlinking all transmitters) Off On 1 second
