		Table 9. Excel 10 Alarms.

		Alarm type
	Name of alarm or error bit	number	Meaning of alarm code or error bit

	RETURN_TO_NORMAL	128U	Return to no alarm after being in an alarm condition. This code is added
			numerically to another alarm code to indicate that the alarm condition has
			returned to normal.

	ALARM_NOTIFY_DISABLED	255U	The alarm reporting has been turned off by the DestManMode. No more
			alarms are reported via nvoAlarm until DestManMode turns on alarm repor
			or upon application restart.

	NO_ALARM	0	No alarms presently detected.

	INPUT_NV_FAILURE	1	One or more NV inputs have failed in receiving an update within their spec
			FAILURE_DETECT_TIME.

	NODE_DISABLED	2	The control algorithm has stopped because the RIO device is in
			DISABLED_MODE, MANUAL, or FACTORY_TEST mode. No more alarms
			reported when the device is in the DISABLED_MODE. Alarms continue to
			reported if the device is in the MANUAL or FACTORY_TEST mode. The
			control is shut down and disabled until power is cycled or the node is reset
			See note 1 below.

	SENSOR_FAILURE	3	One or more sensors have failed.

NOTE: The node can be reset by switching the node to MANUAL and then to the normal operating mode.

Also, the Excel 10 variables, AlarmLogX where X is 1 through 5, that store the last five alarms to occur in the device, are available. These points can be viewed through XBS or E-Vision.

Broadcasting the Service Message

The Service Message allows a device on the E-Bus to be positively identified. The Service Message contains the device ID number and, therefore, can be used to confirm the physical location of a particular Excel 10 in a building.

There are two methods of broadcasting the Service Message from an Excel 10 W7761A Device. One uses a hardware service pin button on the side of the device (see Fig. 24). The other involves using the PC Configuration tool, as follows.

The commissioning tool is used to perform the ID Assignment task (see the E-Vision User’s Guide form, 74-2588).

W7761A Device Status LED

The LED on the front and center of a W7761A Device provides a visual indication of the status of the device. See Fig. 25. When the W7761A receives power, the LED should appear in one of the following allowable states (see Table 10):
