This manual provides essential information for the safe and effective use of your Sumitomo Type-72C+ Fusion Splicer.

2. Setup

Before operating the Sumitomo Type-72C+, ensure all components are present and undamaged.

2.1 Unpacking and Inspection

Carefully remove the splicer and its accessories from the carrying case. Inspect all items for any signs of damage that may have occurred during shipping. If any damage is found, contact your supplier immediately.

2.2 Power Connection

The splicer operates on battery power or can be connected to an AC power source using the provided adapter. Ensure the battery is fully charged before use, especially for field operations. Connect the AC adapter to the splicer's power input and then to a suitable power outlet.

2.3 Initial Placement

Place the splicer on a stable, level surface. The multi-position monitor can be adjusted for optimal viewing angle depending on your working environment.

3. Operating Instructions

The Type-72C+ is designed for user-friendly operation via its touch screen interface.

3.1 Powering On/Off

Press and hold the power button located on the control panel to turn the splicer on. The 5-inch LCD touch screen will illuminate. To power off, press and hold the power button again until the device shuts down.

3.2 Fiber Preparation

1. Strip the Fiber: Carefully remove the fiber coating to expose the bare fiber using a fiber stripper.
2. Clean the Fiber: Clean the bare fiber with an alcohol wipe to remove any contaminants.
3. Cleave the Fiber: Use a high-precision fiber cleaver (e.g., FC-6S) to create a clean, perpendicular fiber end face. A proper cleave is crucial for low-loss splices.

3.3 Splicing Procedure

1. Place Fibers: Open the wind protector and fiber clamps. Carefully place the prepared fibers into the V-grooves on the splicer, ensuring the fiber ends are positioned correctly between the electrodes.
2. Close Clamps and Protector: Close the fiber clamps and then the wind protector. The splicer will automatically begin the alignment process.
3. Monitor Alignment: Observe the fiber images on the 5-inch LCD screen. The HDCM software will perform core alignment.
4. Initiate Splicing: Once alignment is complete, the splicer will automatically initiate the fusion process. The ultra-fast splicing cycle will complete in approximately 5 seconds.
5. Splice Loss Estimation: After splicing, the device will display an estimated splice loss.
6. Remove Fiber: Open the wind protector and fiber clamps. Carefully remove the spliced fiber.

3.4 Heat Shrink Protection

Place a fiber protection sleeve over the spliced area and position it in the splicer's built-in heater. Close the heater cover. The ultra-fast heating cycle will complete in approximately 9 seconds (for 60mm sleeves), shrinking the sleeve to protect the splice.

4. Maintenance

Regular maintenance ensures the longevity and optimal performance of your Sumitomo Type-72C+ Fusion Splicer.

4.1 Cleaning

• V-Grooves and Electrodes: Regularly clean the V-grooves and electrode area with a cotton swab moistened with isopropyl alcohol. Dust and fiber debris can affect splicing performance.
• LCD Screen: Use a soft, lint-free cloth to clean the touch screen. Avoid abrasive cleaners.
• Exterior: Wipe the exterior of the splicer with a damp cloth. The IP52 rating provides protection against dust and water splashes, but proper cleaning is still recommended.

4.2 Electrode Replacement

Electrodes have a limited lifespan and will need to be replaced periodically. The splicer will typically indicate when electrode replacement is necessary. Refer to the detailed electrode replacement procedure in the full service manual or contact authorized service personnel.

4.3 Software Updates

The Type-72C+ supports software updates via the internet. Periodically check the official Sumitomo website for the latest software versions to ensure your splicer has the most current features and performance enhancements.

5. Troubleshooting

This section addresses common issues you might encounter with your fusion splicer.

5.1 Power Issues

• Splicer does not power on: Ensure the battery is charged or the AC adapter is properly connected to a working power outlet. Check the power button for proper engagement.
• Battery not charging: Verify the AC adapter connection. If the issue persists, the battery or adapter may need replacement.

5.2 Splicing Problems

• High splice loss: This can be caused by improper fiber preparation (poor cleave, dirty fiber), worn electrodes, or dust in the V-grooves. Re-cleave and clean fibers, clean V-grooves, or replace electrodes as needed.
• Fibers not aligning: Check for debris in the V-grooves or on the fiber clamps. Ensure fibers are correctly placed.
• Arc discharge failure: This may indicate worn electrodes or an issue with the arc power. Replace electrodes or contact service.

5.3 Display Issues

• Screen unresponsive: Try restarting the splicer. If the issue persists, contact technical support.
• Image unclear: Ensure the camera lenses are clean.

For persistent issues not covered here, please refer to the comprehensive service manual or contact authorized Sumitomo technical support.
