The Brecknell SBI-505 Indicator is a versatile device designed for basic weighing functions, offering a range of features for efficient and accurate measurement. It supports operations such as zeroing, taring, displaying gross and net weights, accumulation, printing, and animal weighing. The indicator is capable of displaying measurements in both kilograms (kg) and pounds (lb).
The core function of the SBI-505 is to provide precise weight readings. It includes an initial zero setting feature, where the indicator automatically displays zero if the weight on the scale is within the initial zero tolerance during power-up. A center of zero and stable annunciator will illuminate to confirm this. For manual zeroing, users can press the "Zero" key when the scale is stable and not showing a negative weight, provided the weight is within tolerance.
Tare operations are straightforward: when a gross weight is tared, the indicator switches to display the net weight, with the "Net" and "Tare" annunciators lighting up. To clear the tare weight and revert to gross weight display, the "Tare" key can be pressed.
The device also supports a printing function. If the weight is stable, pressing the "Print" key will send the weight data to a connected printer. The default print format includes the serial number, gross weight, net weight, tare weight, date, and time.
Counting items of the same weight is another key feature. This involves a simple process: first, clear the scale with the "Zero" key. Then, load a pre-counted sample (e.g., 5, 10, 20, 50, 100, 200, or 500 pieces) and press the "Count" key. The display will show "PCS 0". Users can then select the desired sample quantity using the "Zero" key and confirm with the "Print" key. After removing the sample and zeroing the scale, the items to be counted can be loaded, and the quantity will be displayed. Pressing "Count" again returns the device to weighing mode. For items with a different piece weight, the unit must be turned off and on again, and the counting process repeated.
Accumulation is a useful feature for totaling multiple weights. Starting with a zero display, the first weight is added to the scale, and the "Total" key is pressed to enter accumulation mode. The "Total" annunciator turns on, and the display shows "n 001" before reverting to the loaded weight. After unloading, subsequent weights can be added and accumulated by pressing the "Total" key again, up to a maximum of 999 times. To view accumulated values, the "Total" and "ON/OFF" keys are pressed and held. The display will show "nnn" (the number of accumulations) followed by the total accumulated weight. If the total exceeds the display capability, it will show the first four digits, then the last four digits. Clearing the accumulated weight involves holding the "Total" key while viewing the last four digits of the total, then toggling between "clr n" (no clear) and "clr y" (clear) using the "Zero" or "Tare" keys, and finally accepting the choice with the "Print" key.
The SBI-505 offers various configuration options through its parameter setting menu. This menu is divided into calibration and parameter configuration sections. Accessing these sections requires specific key combinations and, for calibration, may involve a "Seal switch" on the main board.
The indicator supports different output formats for communication with peripheral devices. Option 2, "PRINT key only," sends a detailed format including net weight, tare weight, gross weight, time, and date when the "Print" key is pressed in net weighing mode. In gross mode, the net and tare lines are omitted.
Option 3, "Host commands," allows the indicator to respond to specific ASCII commands (T for Tare, Z for Zero, P for Print, R for Gross/Net Weight, C for Kg/lb conversion) with corresponding data formats. For example, the "R" command triggers a response that includes weight data, units (lb/kg), and gross/net status.
Option 4, "Continuous Send," provides a continuous output string that includes ASCII characters, gross/net status, polarity, weight data, units, carriage return, and line feed.
Option 5, "Host Device/Remote Display (RD65)," is compatible with the Brecknell RD65 remote display and other host devices. This option sends a structured output format including start of text, polarity, weight data, units, gross/net status, stability status, carriage return, and line feed.
The manual provides a comprehensive troubleshooting guide for common errors. For instance, "UUUUUU" indicates an overload, wrong load cell connection, or a load cell problem. Solutions include reducing weight, checking connections, and inspecting the load cell's voltage or resistance. "Nnnnnnn" suggests an underload, LC connection issue, or load cell problem, with similar troubleshooting steps.
Calibration-related errors like "ERR1" (no input weights or overload during calibration) require inputting correct weights. "ERR2" (weights below minimum during calibration) suggests using weights between 60% and 80% of the maximum capacity. "ERR3" (negative input signal during calibration) points to connection issues or a faulty load cell. "ERR4" (unstable signal during calibration) advises waiting for the platform to stabilize before calibrating. "ERR5" indicates a need to change the PCB, and "ERR6" signifies no load cell signal.
The device also allows for resetting configuration parameters to their default settings. This is done by placing the Cal switch in the "ON" position and selecting the "restore default parameters" option in the menu. However, users are cautioned against doing this after making new parameter settings to avoid losing them.
The SBI-505 is designed for ease of use and maintenance, with clear instructions for operation, calibration, and troubleshooting, ensuring reliable performance in various weighing applications.
