(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 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.

8.8Open Echelon Device Connectivity

Open-Echelon E2s must be ordered pre-configured from Retail Solutions. Open-Echelon licenses must be purchased and enabled on units, and are not transferrable to other units without assistance from Retail Solutions. Call 770-425-2724for technical assistance or your sales representative. Your sales representative will know which devices your unit will connect to.
