4. Setup
4.1 Unpacking and Inspection
Carefully remove the component counter from its packaging. Inspect the device for any signs of damage during transit. Report any damage to your supplier immediately.
4.2 Mirror Installation
- Use a hexagonal wrench to loosen the two hexagonal screws on the back of the material point machine.
- Align the mirror with the holes on the machine and tighten the screws securely.

Figure 4.1: Visual guide for mirror installation. The image shows loosening screws with a hexagonal wrench, aligning the mirror, and tightening the screws.
4.3 Material Tray Installation
- Use a screwdriver to tighten the two screws on the shaft.
- Align the holes of the material tray with the shaft and tighten the screws.

4.4 Power Connection
Connect the power cord to the machine and then to a suitable AC 220V/110V power outlet. Ensure the power switch is in the OFF position before connecting.
5. Operating Instructions
5.1 Control Panel Overview

Figure 5.1: Detailed view of the control panel, showing number keys, function keys, and their descriptions. This includes keys for setting material spacing (PITCH), switching material point speed, external printer output (PRINT), material quantity, forward/reverse start (LEFT/RIGHT), stop/clear (STOP/CLEAR), and leak detection (LOSS).
5.2 Display Information

Figure 5.2: The LCD display shows the current operating mode (A: Material delivery mode, M: Inventory mode), material spacing (PITCH), preset quantity in A mode, total number of points (count), and speed setting (L: low, M: medium, H: high speed).
5.3 Basic Counting Operation
- Power On: Flip the power switch to the ON position. The LCD display will illuminate.
- Select Mode: Use the "SELECT" key (up arrow) to switch between "A: Material delivery mode" and "M: Inventory mode".
- Set Material Spacing (PITCH): Press the "PITCH" key and use the number keys to input the correct spacing for your component tape. Press "ENTER" to confirm.
- Set Speed: Use the speed adjustment keys (usually integrated with other function keys or a dedicated switch) to select Low (L), Medium (M), or High (H) speed.
- Load Component Reel: Place the component reel onto the appropriate reel holder. Guide the tape through the counting mechanism.
- Start Counting: Press the "RIGHT" key to start counting in the forward direction. Press "LEFT" for reverse.
- Stop Counting: Press the "STOP/CLEAR" key (short press) to pause or stop the counting process.
- Reset Count: Long press the "STOP/CLEAR" key to reset the counted quantity to zero.
5.4 Leak Detection Function
The YS-802 features an enhanced leak detection model. If the machine detects a missing component (leakage) during counting, it will typically stop and indicate an error. Refer to the "LOSS" indicator on the control panel.

Figure 5.3: This image highlights the YS-802 as an enhanced leakage detection model, noting its all-steel body, real-time leakage detection function, imported fiber optic sensing device, and 42 stepper motor, making it suitable for all reel-mounted electronic materials.
6. Maintenance
6.1 Cleaning
- Regularly clean the exterior of the machine with a soft, dry cloth.
- Ensure the photoelectric sensors and tape path are free from dust and debris to maintain counting accuracy. Use a soft brush or compressed air if necessary.
- Do not use abrasive cleaners or solvents.
6.2 Optical Fiber Leak Detection Adjustment
The distance between the upper and lower aluminum columns can be adjusted for optimal optical fiber leak detection. This adjustment ensures accurate detection across various tape thicknesses.

Figure 6.1: This image illustrates the YS-802 enhanced leak detection model, specifically showing the adjustable distance between the upper and lower aluminum columns, which is crucial for adjusting the optical fiber leak detection mechanism.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Machine does not power on. | No power supply; power cord loose; power switch off. | Check power connection; ensure power switch is ON; test power outlet. |
| Inaccurate counting. | Sensors dirty; incorrect material spacing (PITCH) setting; damaged tape. | Clean sensors; verify and adjust PITCH setting; inspect component tape for damage. |
| Machine stops unexpectedly. | Component leakage detected; tape jam; power interruption. | Check for missing components; clear any tape jams; verify stable power supply. |
| Display not working. | Power issue; display malfunction. | Check power; if power is present, contact support. |
