Disconnecting

If the vehicle reaches a point of the overhead system, where the overhead lines end, the GPS unit recognizes this. The corresponding control unit sends a control command to the main computer, which accordingly initiates a wiring off process. Alternatively the wiring off command can be triggered by the driver (e.g.: in case of disturbances on the route or an unscheduled deviation).

• Signal for wiring off
• Filling the cylinders for pivoting motion to enable a specific movement
• Lowering the trolley poles to disconnect from overhead line
• Moving the poles to center position
• Lowering the poles to deepest position (roof of the vehicle)
• Locking the poles
• Trolley collector is in non-operating mode now
