6. Installation and Wiring
Wiring Diagram:
Refer to Image 1 in Section 4 for a visual guide to the connection points.
Connection Steps:
- Identify Terminals: Locate the terminals labeled 'Battery', 'Charger', and 'Load' on the module.
- Connect Battery: Connect your battery to the 'Battery' terminals. Ensure correct polarity (positive to positive, negative to negative).
- Connect Charger: Connect your battery charger to the 'Charger' terminals. Ensure correct polarity.
- Connect Load: Connect your electrical load (device to be powered by the battery) to the 'Load' terminals. Ensure correct polarity.
- Power On: Once all connections are secure, apply power to the charger. The module will automatically begin monitoring the battery voltage.
Note: Always double-check all connections before applying power to prevent short circuits or damage.
7. Operation
Automatic Charging Function:
The YX-1708 module automatically monitors the battery voltage. When the battery voltage drops below a preset threshold (under-voltage), the module will activate the charger to begin charging the battery. Once the battery reaches its full charge voltage (over-voltage), the module will automatically stop charging to prevent overcharging.
Indicator Lights:
- Power Supply Indicator (Green LED): This light illuminates when the module receives power.
- Load Working Indicator (Red LED): This light indicates the status of the load. It will be off when the battery is charging and on when the battery is discharging to power the load.
Forced Start Function:
The module includes a 'forced start' function, primarily for the load. This function allows the load to be activated even if the battery voltage is not within the normal operating range for automatic load activation.
Image 3: The two points indicated by the red line are for activating the forced startup function. Connecting these two points will force the load to start.
- Activating Forced Start: To activate the forced start for the load, temporarily connect the two designated points on the circuit board as shown in Image 3.
- Functionality: This action will force the load to operate. Note that the forced start function is specifically for the load and does not affect the charging process.
8. Maintenance
- Regular Inspection: Periodically check all wiring connections to ensure they are secure and free from corrosion.
- Cleanliness: Keep the module clean and free from dust and debris. Use a soft, dry cloth for cleaning.
- Environmental Conditions: Ensure the module is operating within its specified environmental conditions (temperature, humidity).
- Avoid Physical Damage: Protect the module from impacts or excessive vibrations.
9. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Module not powering on (Green LED off) | No power supply to the module or incorrect wiring. | Check power connections to the 'Charger' terminals and ensure correct polarity. Verify power source is active. |
| Battery not charging | Battery voltage is above the low threshold, charger not connected, or charger malfunction. | Verify battery voltage is below the charging threshold. Check charger connections and ensure the charger is functional. |
| Battery overcharging | Module malfunction or incorrect voltage setting. | Disconnect charger immediately. Verify module functionality. Ensure the module is rated for your battery voltage. |
| Load not receiving power | Battery voltage is too low, load not connected, or load malfunction. | Check battery voltage. Ensure load is correctly connected to 'Load' terminals. Test the load independently. Use the forced start function to test the load connection. |
| Red LED always on/off incorrectly | Module malfunction or incorrect wiring. | Verify all connections. If the issue persists, the module may be faulty. |
