troller's display is highlighted red.
The NCD controller sends optical commands via the TX connections to the control
unit in the chamber's lower compartment. This unit converts the optical commands
to electrical signals and forwards them to the azimuth turntable and to the elevation
positioner. The return path for control communication uses the RX connections.

Testing Safety Systems
When the door is open, the chamber's lower interlock system (
) must prevent
any positioner movement. You can check whether the interlock is functioning properly
by opening the door; the positioner has to stop moving.
To test the interlock
1. Make sure that the chamber is connected to power; see
2. Make sure that the chamber is connected to control; see
Chapter 7.3.3, "Opening the Door"
4. Take note of the positioner's position.
5. Close the door; see
Chapter 7.3.4, "Closing the Door"
6. Send a command from the controller to start movement of the positioner.
7. Open the door.
8. Check the positioner as follows:
●
Test passed
If the positioner has moved, but is now no longer moving, the interlock suc-
cessfully stopped movement when the door was opened.
●
Test result is unclear
If the positioner has not moved from its original position noted in
possible to state unequivocally that the interlock is functioning properly.
●
Test failed
If the positioner continues to move when the door is open, the interlock has
failed.
