Installation
The Beacon II Smart Controller should be installed in a location that allows for easy viewing of the LCD display while ensuring a secure and vibration-free environment. Proper placement is crucial, avoiding areas subject to extreme temperatures below 40°F or above 100°F. When installing the controller, it is essential to separate the 24-volt wiring from the line voltage wiring for safety and optimal performance. All low-voltage wiring must be at least 18 gauge and kept separate from high-voltage wiring. The maximum distance between the Beacon II Smart Controller and the Master Evaporator should not exceed 1000 feet. Adherence to these guidelines ensures a successful and reliable installation.
Wiring
The terminal strip in the Beacon II Smart Controller is labeled similarly to the Beacon II boards. Connect the corresponding terminals on the Beacon II Smart Controller to those on the Beacon II board. For single Refrigeration systems, connect MULTI OUT 1 from the Beacon II Smart Controller to the MULTI IN on the Beacon II board at the Evaporator. For multiple systems, the wiring process is slightly different. Connect MULTI OUT 2 from the Beacon II Smart Controller to the MULTI IN on the Beacon II board in the second system. Then, connect MULTI IN 2 from the Beacon II Smart Controller to the MULTI OUT on the Beacon II board in the second system. The wiring is crucial for the controller to communicate effectively with the refrigeration system. Refer to the wiring diagram for detailed instructions on connecting the various components.
Power Supply
The Beacon II board obtains its 24 VAC power supply from a transformer mounted in the electrical end of each evaporator. On 208-240 volt systems, the multi-tap transformer is shipped from the factory pre-wired for 240 volts. If your supply voltage is 208 volts, you must change the transformer wiring to accommodate this voltage. The transformer is essential for providing the necessary power to the Beacon II board. The Beacon II Smart Controller itself also requires a separate power supply. It is crucial to ensure that the power supply is functioning correctly and is providing the required voltage to the Beacon II board and the Smart Controller for optimal system operation. Any issues with the power supply can result in malfunctions or errors in the refrigeration system.
Button Functions
The Beacon II Smart Controller features a user-friendly interface with a set of buttons that allow you to control and monitor various aspects of the refrigeration system. The “COOL” button initiates the cooling cycle, bypassing the 4-minute hold-off period. The “DEFROST” button starts the defrost cycle. The “OFF” button shuts down the system. The “SETPOINT” button allows you to adjust the setpoint temperature for the refrigeration system. The “ENTER” button confirms your selections after using the SETPOINT button. The “UP” and “DOWN” buttons navigate through menus and adjust settings. The “MODE” button selects between different operating modes like cooling, defrost, or off. Understanding the functions of these buttons is essential for effective operation and troubleshooting of the Beacon II Smart Controller.
Error Codes
The Beacon II Smart Controller utilizes a system of error codes to indicate potential issues within the refrigeration system; These codes are displayed on the LCD screen and provide valuable information for troubleshooting. For example, “EXVSET” indicates an error with the expansion valve step setting, while “SUCTMP” signals a problem with the evaporator suction temperature. “SSVTMP” signifies an error with the suction sensor voltage temperature, and “SUPLO” alerts you to a superheat that is too low. “SHTDN” indicates a compressor shutdown due to various factors such as high or low refrigerant pressure or low oil pressure. Understanding these error codes is crucial for efficiently identifying and resolving issues within the Beacon II system, ensuring smooth and reliable refrigeration operation.
Alarm Codes
The Beacon II Smart Controller employs alarm codes to alert you to potential problems within the refrigeration system. These codes are displayed on the LCD screen and provide valuable information for troubleshooting. For instance, “SPSEN” indicates a short, open, or missing suction pressure transducer, while “ODSEN” signals an issue with the outdoor temperature sensor. “SUPLO” indicates a superheat that is too low, and “SHTDN” indicates a compressor shutdown. The alarm codes will flash alternately with the normal display information to draw your attention to the issue. By understanding and responding to these alarm codes, you can proactively address potential problems and maintain the optimal performance of your Beacon II system.
Data Logging
The Beacon II Smart Controller offers a powerful data logging feature, enabling you to record and analyze real-time system performance.
