Circuit Diagram Tool

Interactive support of maintenance personnel on site

Logistics Support

The circuit diagram tool is used for the interactive support of maintenance personnel on site.It permits the graphic display of electrical and functional interrelationships and possible causes of faults in the system on the basis of ascertained failures. Intuitive operation enables the user to get a quick and real overview of the operational sequences and interrelationships.

The tool supports the user in his service and training activities in a manner appropriate to the situation. Optimised and quicker detection of faults improves the availability of vehicles and weapon systems. The circuit diagram tool can be integrated into the Advanced Technical Helpdesk Environment (Athene) together with other applications. Effcient repair is ensured by quick andinteractive remote support of the service personnel on site.
