Need help?Do you have a question about the Furuno BC-6158 and is the answer not in the manual?
Details the connection of the BC-6158 charger to the battery monitor circuit and its operational functions.
The BC-6158 is a battery charger designed to manage and maintain the charge of various battery types, specifically clad type or pasteboard vent type batteries, with capacities up to 300 AH. It operates as a constant voltage/current charger, providing a stable output of 28 V and a charging current that can be adjusted to either 20 A or 30 A, depending on the battery's capacity.
The primary function of the BC-6158 is to charge batteries efficiently and safely. It incorporates a sophisticated control system that allows for both automatic and manual charging modes. In "AUTO" mode, the charger intelligently monitors the battery voltage. It initiates charging when the battery voltage drops to between 24.5 V and 25.0 V and automatically ceases charging when the battery reaches a full charge, typically between 28.0 V and 28.5 V. This automatic operation is crucial for preventing over-discharge and ensuring the longevity of the battery. The "AUTO" position is specifically designed to prevent over-discharge and is not intended for "floating operation," where both the battery and AC/DC supplies are used simultaneously.
For situations requiring continuous charging, the "MANUAL" mode can be selected. In this mode, the charger will continue to supply current to the battery without automatic cutoff based on voltage. The charging process is controlled by a "CHARGE-L" signal, which activates or deactivates relay K1 on the AC power supply line of the BC-6158.
The charger's power supply is connected to a tap on transformer T1, which is selected based on the incoming supply voltage. This ensures that the charger receives the correct input voltage for optimal operation.
A critical safety feature of the BC-6158 is its thermal sensor, mounted on the heat radiator. This sensor monitors the internal temperature of the charger and activates if the temperature exceeds 60 degrees Celsius, preventing potential damage due to overheating.
The BC-6158 also integrates with a battery monitor circuit (05P0607), which continuously tracks the battery voltage. Should the battery voltage fall below 22 V, a "LOW" indicator will illuminate, and an audible buzzer will sound, alerting the user to the low battery condition.
Furthermore, the charger is designed to interact with other systems, such as the PR-850A (AR). An "AC FAIL" signal is generated by the PR-850A (AR) if the AC supply is interrupted, indicating a switch to battery power. This signal is sent to the battery monitor board (specifically to "2. EMG-L") to indicate "IN USE" status. This "AC FAIL" signal is also transmitted to other connected devices like the FS-5000/2550/1562-25, which then automatically reduce their transmission power to between 60 W and 70 W to conserve battery life.
The BC-6158 offers user-friendly controls for managing battery charging. The "BATT CHARGER switch" on the console panel allows users to select between "AUTO" and "MANUAL" charging modes, providing flexibility based on operational needs. The automatic mode simplifies battery maintenance by handling the charging cycle without constant supervision, making it ideal for routine use.
The maximum charging current can be adjusted via VR2, allowing the user to set it to either 20 A or 30 A to match the specific capacity of the battery being charged. For instance, a 200 AH battery would typically use a 20 A setting, while a 300 AH battery would require a 30 A setting. The output voltage of the charger can be precisely adjusted to 28 V using VR1. These adjustments ensure that the battery is charged at the optimal current and voltage, promoting battery health and extending its lifespan.
Visual indicators, such as the "LOW" indicator and the "IN USE" status, provide immediate feedback on the battery's condition and the system's operational state. The audible buzzer for low battery conditions ensures that critical alerts are not missed.
Maintenance of the BC-6158 involves periodic checks and adjustments to ensure its continued optimal performance. The adjustable VR1 and VR2 potentiometers allow for precise calibration of the output voltage and maximum charging current, respectively. These adjustments can be performed as part of routine maintenance or when changing battery types with different capacity requirements.
The thermal sensor is a key component for safety and longevity. While it operates automatically, ensuring that the charger's heat radiator is free from obstructions and dust is important to facilitate efficient heat dissipation. Regular cleaning of the radiator can prevent the thermal sensor from triggering unnecessarily and ensure the charger operates within safe temperature limits.
The modular design, with components like the battery monitor circuit (05P0607) and the power control board, facilitates easier troubleshooting and repair. Access to terminals like TB1, TB2, and TB3 allows for straightforward connection and disconnection of battery and AC power lines, simplifying installation and maintenance procedures.
The presence of a breaker (CP1) provides overcurrent protection, safeguarding the charger and connected systems from electrical faults. Regular inspection of the breaker and other protective components is part of good maintenance practice.
Overall, the BC-6158 is designed for reliable and efficient battery management, offering both automatic and manual control options, integrated safety features, and provisions for easy adjustment and maintenance.
