(2 × 4VA ) + (1 × 40VA ) = 48VA

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.

8.7LEDs

The Echelon Board LEDs can be used to determine the status of normal operating parameters for the board.

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 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.
