Refer to the installation guides on the next few pages 

for instructions on how to install these boards on the Eche-
lon Network.

The Echelon Board LEDs can be used to determine the 

status of normal operating parameters for the board.

ON: The Echelon port is being 
held in reset or if momentary it 
means the board has gone 
through reset

During normal operation this 
LED should be off. If the Service 
Pin is pressed, this LED will 
come on.

If the LED is blinking, the node 
does not have its Subnet/Node 
address set. (E2 should set this 
during the first power -up se-
quence where the user will be 
asked in which Subnet to put the 
controller (E2 will always be 
Node = 1 on the network). 

If the LED is blinking, then try 
resetting the E2. If this does not 
correct the problem, replace the 
Echelon board.

ON (no blinking): Replace the 
Echelon board. The Neuron pro-
cessor has lost its application 
program.

Open-Echelon E2s must be ordered pre-configured 

from Emerson Retail Solutions. Open-Echelon licenses 
must be purchased and enabled on units, and are not trans-
ferrable to other units without assistance from Emerson 
Retail Solutions. Call 770-425-2724 for technical assis-
tance or your sales representative. Your sales representa-
tive will know which devices your unit will connect to. 

Login to the controller and enter the desired number of 

Echelon devices to be added in the Connected I/O screen.
