RLJ-2000B Flow Accumulator User Manual Core Overview This manual mainly covers the usage method and common troubleshooting solutions of RLJ-2000B Flow Accumulator. The following is the key content summary:
1. Product Function Overview RLJ-2000B Flow Accumulator is an intelligent instrument used for flow measurement and accumulation calculation, supporting multiple signal inputs (such as pulse, 4-20mA current), and can be adapted to different types of flow sensors (such as vortex street, electromagnetic, and turbine flow meters). Its core functions include real-time traffic display: displaying instantaneous traffic values through digital or graphical interfaces. Cumulative traffic calculation: Automatically record and store total traffic data, supporting periodic statistics such as shifts, days, and months. Alarm function: The upper and lower limit thresholds of flow can be set, and an audible and visual alarm will be triggered when the limit is exceeded. Data output: Provide 4-20mA analog signal output or RS485 digital communication interface for easy connection with the upper computer system.
2. Instructions for use Installation and wiring Connect the flow sensor signal line to the corresponding input terminal of the integrator (such as the pulse input terminal or current input terminal).
. Connect the power cord to the AC220V or DC24V power supply module (depending on the model). If remote monitoring is required, connect the RS485 communication line to the PLC or computer. Parameter setting instrument coefficient setting: Input pulse equivalent based on sensor calibration v
III. Common faults and solutions: Reasons for no flow display: sensor not powered, signal line disconnected, instrument parameter settings incorrect.
. Solution: Check the sensor power supply and wiring; Recheck the instrument coefficient settings. The reasons for large fluctuations in flow display are pipeline vibration interference and improper installation of sensors (such as near the pump outlet). Solution: Adjust the installation position of the sensor and add shock absorption measures; Check if the instrument filtering parameters are reasonable. The reason for the large cumulative flow error is that the instrument coefficient has not been calibrated and the sensor performance has decreased. Processing: Compare and calibrate using standard flow meters; Replace the sensor and recalibrate it. Reason for communication abnormality: RS485 wire reversed, mismatched baud rate setting. Solution: Check the communication line sequence; Unify the baud rate between the upper computer and the instrument (such as 9600bps). 4. Maintenance and Regular Calibration: It is recommended to calibrate with a standard flow meter every 6 months to ens
