2.11.4.3 Motor Nodes
Every motor node has collision detection on its own movement. A collision can be detected
in different ways, for instance if the control error in the motor node's regulator is too large, if
the final position is not reached in time, or if the position transducer has not moved although
the drive unit had an output voltage for a given time.
A detected collision stops all movements in that part of the System (e.g. OTC, Table or Wall-
stand) where the collision is detected. An error message is displayed.
2.11.4.4 Malfunctioning Node
If any node stops functioning, all movements are stopped and the power to the motors in the
System is removed.
2.11.5 Quick abortion of an auto positioning
When any of the buttons on the stand is pressed while the stand is moving toward its posi-
tion, it has the same effect as when the servo button is released, all movements are stopped.
2.11.6 Opposite buttons pressed
If, at any time, two from each other opposite buttons are pressed, for example movements
up and down, the movement is stopped. Both buttons must be released before any move-
ment is allowed.
2.11.7 Dead man’s grip
All movements require constant activation of the chosen button.
If the operator releases one of the buttons/controls, the system will immediately stop or en-
gage the brakes (manual movements). The exposure operator console has the same
functionality.
