Diakont D40 Radiation Tolerant Cameras offer exceptional resolution, sensitivity, and radiation tolerance. For best results the camera should be properly maintained and have a good CRT tube installed.
Replacement of the CRT tube is fast and easy, since no tuning is required – but care should be taken such that camera components are properly handled. The following guide is meant to be used as an overview, and should not be used in place of appropriate training.
1.) Assemble required materials:
- General knowledge of safe D40 operation and maintenance practices
- Replacement tube and tuning board
- Spanner tool (4026)
- Tube removal tool (4038)
- Small thin-blade slotted screwdriver
- Lint-free cloth
- Gloves
- Compressed dry air
- 1:1 alcohol-ether mixture
Note: Before starting this process, connect the Camera to the CCU and turn power on; “Focus Near” until the Focus Motor stops. This moves the Tube and Focusing Assembly backward in the Module, so that it is more-accessible during removal and installation.
2.) With the Camera Module removed from the Housing, and the Lens removed, unscrew the 8 small fasteners that hold the Lens Mounting Bracket in place, and remove the bracket.
3.) Remove the 2 small screws that hold the Anti-lag Cover in place, and remove the cover.
4.) Unscrew and remove the Anti-lag Board Locking Nut located in front of the Tube using the short pins of spanner 4026.
5.) Carefully disconnect the 2-pin Anti-lag Board connector from the Ring Board, and remove the Anti-lag Board.
6.) Unscrew the Tube Locking Nut using the short pins of spanner 4026, and remove the nut.
7.) Disconnect the wiring harness from the Tuning Board and remove 4 screws holding the board in place. Carefully lift the board, disconnect the wire connector from the bottom of the board, and remove the board.
8.) On the opposite side of the Camera from the Tuning Board is the Intermediate Amplifier Board; disconnect the wire connector from the top, remove the 4 screws, and lift the board out of the way (NOTE: It is OK to leave the wiring harness connected to the Intermediate Amplifier Board, and just setting the board slightly aside).
9.) Using a small slotted screwdriver, carefully disconnect the Tube from the tube connector.
10.) Use the Tube Removal Tool 4038 to remove the old Tube - slide the shoehorn side into the front of the Focusing Assembly so that the end of the tool is flush with the Tube (this protects the pogo pins on the front of the Tube). Align the tube connector so that its sockets do not line up with the tube pins, and push on the connector so that the Tube moves forward and can be accessed from the front of the module (NOTE: Be careful not to shoot the tube across the room!). Slide the old Tube out of the Focusing Assembly.
11.) With the Tube removed, inspect module internals for debris, and blow out with dry air. Unpack the new tube and tuning board.
12.) Align the short pin of the new tube with the red dot located on the white connector (usually also aligned with iris drive axle). Cradle the new Tube with the 4038 tool, and fully insert the Tube into the Focusing Assembly.
13.) Mate the connector to the Tube, ensuring that the red dot aligns with the short pin. Attach the connector by pushing in on the 4038 tool while also pushing in on the connector, until it is firmly seated.
14.) Reinstall the Intermediate Amplifer PCB, ensuring the connector is secure.
15.) Install the new Tuning Board, ensuring that both the bottom and top connectors are secure.
16.) While still accessable, ensure that the Tube front window is clean and free from debris; use a lint-free cloth, canned air, or ether/alcohol mixture to clean the tube window.
17.) Carefully align the threads of the Tube Locking Nut. Screw in the nut as far as possible using the short pins of spanner 4026, until hand-tight.
18.) Reinstall the Anti-lag Board, ensuring that it is flat and level with the locking nut. Connect the wire harness to the Ring Board, making sure the red wire is oriented toward the outside of the camera module. Run the wires through the slot of the tube holder.
19.) Reinstall the Anti-lag Locking Nut using the short pins of spanner 4026; screw the nut in as far as possible until hand-tight.
20.) Reinstall the Anti-lag Cover and 2 fasteners.
21.) Reinstall the Lens Mounting Bracket and 8 fasteners.
