Operational sequence, closing vario roof (VR) - AD77.50-P-2000-24A

Operational sequence, closing vario roof 

Starting position: vario roof opened

Every picture illustrates a procedural step with the limit switches actuated, together with the energizing status of the hydraulic unit and power windows that is required for the next procedural step to be reached.
