9.4.3 Mounting the Tube Closures
9.4.3.1 Installing the Tube Closure – Standard Equipment
Only open the compressed air valves after connecting all connecting hoses. Otherwise
uncontrolled door movements could damage the door and the process tube.
1. Switch off the compressed air at the pressure reducing valve within the toxic gas
exhaust.
2. Open the throttle valves to allow manual movements of the tube closure up to the
stops.
3. Mount the quartz stopper supports on the tube closure. Manually tighten the
screws.
4. Move the tube door closure lever into the lower moved out position.
5. Screw the quartz stopper with the quartz stopper support onto the tube closure
lever. The quartz stopper must be adjusted centrally to the process tube. The
adjustment is done through left and right slots and through fixing screws with
locknuts in prolongation of the swiveling cylinder.
6. Check the position of the quartz stopper. The distance between process tube end
and tube door must be at least 1 cm when the quartz stopper is moved out.
7. Manually close the tube closure. Set the "Boat SETPOINT – ACTUAL = 0"
command at the CESAR control computer, i.e. the tube closure is closed.
8. Close all throttle valves.
9. Set the compressed air for the toxic gas exhaust to 5 bar at the pressure controller.
10. Use the throttle valve to adjust each movement determined by the CESAR control
computer. There are throttle valves for each direction.
11. Adjust the limit switches.
