Tower status event. If enabled, this trap is sent when the towerStatus indicates an error state ('noComm', 'fanFail', 'overTemp', 'nvmFail', or 'outOfBalance'). This trap is repeated periodically while the towerStatus remains in an error state. If the towerStatus returns to a non-error state ('normal'), this trap is sent once more with the non-error towerStatus, and then stops being repeated. While the towerStatus indicates a 'noComm' error state, all status and load traps are suppressed for input feeds and outlets on the tower.
