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

or upon application restart.

 

 

 

 

 

NO_ALARM

0

No alarms presently detected.

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):
