Ventri System does not pull the table out when UNLOAD key is pushed.

Ventri System does not pull the table out when UNLOAD key is pushed. The table will move down to 76.0 cm but does not proceed to move out of the ring System does not pull the table out when UNLOAD key is pushed. The table will move down to 76.0 cm but does not proceed to move out of the ring. Can hear the linear brake release but linear axis never moves. Brake will engage again. Briefly displays UNLOAD CANCELLED message on the monitor. At this time the table can not be moved out with the RCU either - brake releases but no motion. IF the table is raised a small amount with the RCU to f.ex. 76.1 or 76.3 cm then linear moves with RCU IN/OUT (UNLOAD still doesn't work as it takes vertical back to 76.0 cm). The same issue intermittently happens when the table is positioned using automatic load (SET). It started as intermittent issue but now it happens more like on 60-70 % of all LOADS / UNLOADS CSO #1-1797576527
