Abstract
A control system for controlling the operation of a mobile distribution apparatus is disclosed. The disclosed control system includes an alarm tracking system wherein any errors noted by the control system are recorded in an addressable memory in chronological order. This addressable memory can be read out at any time in order to perform diagnostics and the like. In order to control the length of the list of errors generated by the system, the system will only record the same error three times. Upon the fourth occurrence of a given error, the oldest record of the error is deleted. In addition, the control system classifies errors into distinct categories and provides the user of the system with both audible and visual indications of the occurrence of an error.
