Last week we put in sevice the new ALS completly modified:

_ Main System with new reducer.

_ New Speed parameters for Main System (motor is at full speed but due to reducer the spped is slow). Decceleration sensors not installed since the speed is very slow.

_ All the sensors were replaced by new ones (2 logic embedded in each sensor (NC + NO) ) = only one type of sensor in the ALS. Sensor with connector to ease maintenance.

_ All sensor cabling were changed and new ducts were installed to ease maintenance.

_ The damaged cable of the loadcell was welded again and protected (Heat shrink tube + tape).

_ Add mechanical part to protect loadcell cable when opening over the opening position. It's now impossible to damage Loadcell cable.

_ Increase speed of plier. We add a deceleration sensor in each plier.

_ All the sensors support are new to avoid dammage if there is over position due to manual operation.

The ALS is now functionnal with human interface. The system are so slow 180s !!!, They were not integrated into automatic cycles.

Shifters must manage the Opening/Closing of the ALS at the Start/End od telescope operations.

A new error code is ride up if a door is opened during motion (3002).
