This section covers the installation and replacement of optional accessories such as grating turrets, filter wheels, shutters, and motorized slits.

Grating Turret Replacement
Grating turrets can be interchanged easily, with settings stored for up to three turrets. The procedure includes safety warnings and steps for replacing the turret.

Installing a Filter Wheel
Instructions for installing a filter wheel include aligning it with mounting holes and connecting it to the spectrograph electronics.

Accessing and Changing Filters
Filters can be added or replaced via the filter access hole. The procedure includes using a filter removal tool and synchronizing the filter wheel with the software interface.

Shutter
Accessing the shutter requires removing slit mechanisms, spacers, and filter wheels. Safety warnings are provided regarding the shutter assembly's heat during operation.

Specifications and Procedures
The document provides detailed instructions for handling and operating the Kymera 328i spectrograph. Key procedures include careful handling of motorized input accessories to avoid cable stress, accessing electrical connectors for shutters, and installing slits using supplied screws. A warning is issued regarding the wide aperture slit, which poses a pinch hazard.

Operation
The spectrograph is controlled via the Dashboard interface, which allows users to manage hardware components and acquisition parameters. The interface displays only installed accessories, with options to show all panels for demonstration purposes. Emergency disconnection involves removing the mains power cord.

Detector Controls
Exposure time can be set between a minimum value and 3600 seconds using an edit box or slider bar. The Read Mode Control offers four modes: Full Vertical Binning, Image Readout, Single Track, and Multi-track, each affecting data display differently.

Spectrograph Controls
Reset options are available for wavelength, slit width, and flipper mirror positions. The Wavelength Drive Control sets the system to target wavelengths and controls grating selection. The Step and Glue function allows for composite spectrum creation by merging overlapping spectra.

Grating Turret Control
The Grating Turret Control allows selection of new gratings by rotating the turret. Up to two gratings can be fitted at a time, with additional turrets available for swapping. The software indicates busy status during grating changes.

Key Warnings and Recommendations
- Avoid placing fingers in the input/output slits to prevent injury.
- Ensure proper emergency disconnection procedures are followed.
- Use the appropriate filters to avoid invalidating Relative Efficiency Correction (REC) due to second-order light.

Grating Information and Offset Adjustment
The document describes the process of changing gratings in the Kymera series spectrographs, which takes approximately 20 seconds. Grating information is stored in the spectrograph's EEPROM and can be updated. Each grating turret is equipped with an RFID tag that updates the spectrograph with the new grating information.

The Offset Adjustment function allows calibration adjustments for detector and grating offsets. Detector offsets correct mechanical shifts affecting the displayed spectrum, while grating offsets are specific to each grating. The procedure involves using a spectral light source, resetting offsets, and adjusting them to align spectral lines with the CCD center.

Focus Mirror and Slit Drive Control
The focus mirror function enables precise focus adjustments, either manually or via Auto Focus, which optimizes the focus using an algorithm. Focus positions are stored in the EEPROM.

The Slit Drive Control manages motorized slit assemblies, allowing slit width adjustments between 10 μm and 2500 μm. Narrower slits improve resolution but reduce throughput. Slit width can be adjusted through various methods, including direct input and graphical manipulation.

Filter Wheel and Shutter Control
The Filter Wheel Control manages optional filter wheel accessories, storing filter details in EEPROM. Filters can be selected and modified through a graphical interface.

The Shutter Control offers six modes, including Always Open, Always Closed, and Fully Automatic. Shutter operation can also be managed via external TTL signals, allowing synchronization with other equipment.

Flipper Mirror and Dispersion Optimizer
The Flipper Mirror Control allows rapid selection of input or exit ports by clicking on the desired port.

The Dispersion Optimizer function recalibrates the spectrograph if needed, using multiple wavelengths to ensure accuracy across the spectrum. The process involves selecting gratings and wavelengths, optimizing, and adjusting offsets if necessary.

Section 5: Maintenance

• General Maintenance: The spectrograph contains no user-serviceable parts. Tampering with marked screws voids the warranty. Contact Andor for service.
• Regular Checks: Regularly inspect the product, especially the power supply and mains cable. Ensure the AC mains plug is accessible for disconnection.
• Annual Electrical Safety Checks: Conduct annual checks on insulation and protective earth, but avoid frequent dielectric strength tests to prevent insulation damage.
• Fuse Replacement: Use a SIBA type 70-001-40 4A Ultra Fast fuse internally. For the UK and similar regions, use a BS 1362 type fuse with specific characteristics.
• Cleaning: Use a dry, lint-free cloth for cleaning. If necessary, use a mild detergent solution. Avoid alcohol, solvents, or aerosol cleaners.
• Grating Adjustment: Adjustments may be needed after shipping. Yaw is software-corrected, while roll and tilt require manual adjustment using specific screws.
• Warnings: Removing the lid exposes moving parts and potential pinch points. Follow safety procedures if the lid is removed.

Section 6: Troubleshooting

• Unit Power Issues: Ensure the power lead is correctly connected. Check internal and mains plug fuses if the unit does not power on.
• Grating Information Issues: Check the RFID tag for damage, ensure the turret is correctly mounted, and try restarting the unit.
