2. Use a transformer that has a power rating
equal to or higher than the total calculated
VA (see Table 8-3).
Example: Boards totaling 48VA can be connected to
either a 50VA or 75VA transformer.
Refer to the installation guides on the next few pages
for instructions on how to install these boards on the Eche-
lon Network.

Echelon Board Status
Red (D1) (Reset) ON: The Echelon port is being
held in reset or if momentary it
means the board has gone
through reset
Red (Service) During normal operation this
LED should be off. If the Ser-
vice 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 sequence where the user
will be asked in which Subnet
to put the controller (E2 will al-
ways be Node = 1 on the net-
work).
If the LED is blinking, then try
resetting the E2. If this does
not correct the problem, re-
place the Echelon board.
ON (no blinking): Replace the
Echelon board. The Neuron
processor has lost its applica-
tion program.
