2.2 Connection Ports and Wiring
The device utilizes a connection port for power and signal connections. Follow the wiring diagrams carefully.
- Direct Power Connection: Connect directly to the battery for continuous power.
- Key Switch Power Connection: Integrate with a key switch to power the device on/off with the equipment.
- CAN Communication Connection: For data exchange, connect to your machine's CAN system.
Note: Port 3 must be connected with Port '+' to correctly display battery power progress bars.
2.3 Programmable Battery Types and Voltages
The RL-BI022AC supports various battery types and voltages. These settings are programmable to ensure accurate readings.
Figure 3: Programmable battery types and voltage settings.
- Applicable Battery Types: Lead acid (bt-1/bt-7/bt-8/bt-9), GEL (bt-2), LiFePO4 (bt-3), Trojan (bt-4), AGM (bt-5), 18650 lithium (bt-6).
- Programmable Voltages: 12V (U-12), 24V (U-24), 36V (U-36), 48V (U-48).
3. Operating Instructions
3.1 Battery Power Percentage Display
The device provides real-time battery power information through percentage and a 5-bar LCD progress indicator. Each bar represents 20% of battery power.
Figure 4: Battery power display and low battery reminders.
- Real-time Display: Shows current battery charge level.
- Low Battery Reminder: The red backlight will activate when battery power falls below a preset threshold (e.g., 10% or 30%).
3.2 Total Hours (TOT) and Service Hours (SVC)
The RL-BI022AC tracks total operating hours and provides a service reminder function.
Figure 5: Total hours (TOT) and Service hours (SVC) display.
- TOT (Total Hours): Records the cumulative running hours of the machine when power is on. Initial hours can be set for new meter replacement.
- SVC (Service Hours): Performs regular maintenance task reminders by countdown. A flashing LED light indicates when service hours are approaching or have arrived.
3.3 Battery Voltage Measurement
The device measures and displays the real-time battery voltage. It also provides alerts for voltage anomalies.
Figure 6: Battery voltage measurement and alert indicators.
- Real-time Voltage: Displays the current battery voltage when powered on.
- Voltage Alerts: Reminds the user of voltage exceedance (range: 12V to 60V) or lack (range: 8.5V to 59V) based on preset alert values.
3.4 CAN for Data Transfer
The RL-BI022AC can exchange working data via two built-in CAN frames, provided your machine has a corresponding CAN setup.
- Standard Frame (SId): Default ID: ID0X18FF0b50.
- Extended Frame (EId): Default ID: ID0X201.
3.5 Backlight Display
The white backlight assists in viewing the display in low-light conditions. The backlight can be configured for always-on, off, or automatic mode. A red backlight indicates low battery status or voltage alerts.
4. Maintenance
The RL-BI022AC is designed for durability and minimal maintenance. Regular checks and adherence to service hour reminders are recommended.
- Scheduled Maintenance: Utilize the SVC hour function to arrange and perform regular maintenance tasks for your equipment.
- Cleaning: Wipe the display with a soft, damp cloth. Avoid abrasive cleaners.
- Water Resistance: The device features IP68 water resistance, allowing it to function normally up to 10 meters underwater. However, avoid prolonged submersion unless necessary and ensure all connections are properly sealed.

5. Troubleshooting
If you encounter issues with your Runleader RL-BI022AC, consider the following general troubleshooting steps:
- No Display: Check power connections and ensure the device is receiving adequate voltage. Verify that Port 3 is correctly connected to Port '+'.
- Incorrect Readings: Ensure the correct battery type and voltage settings are programmed for your specific battery.
- CAN Communication Issues: Verify your machine's CAN setup and ensure proper wiring to the device's CAN ports.
- Backlight Malfunction: Check backlight settings (always-on, off, automatic).
