The instrument has an active unbalance function as standard that signals if the load is unevenly distributed, compared to the condition saved via step STR.UNB. Imbalance occurs when the load distribution percentage value on a cell deviates by at least 10% for more than 3 seconds. 10 Visit our website www.RiceLake.com Example: 25% 25% Programming Errors 34% 23% 45% 20% 65% 15% 25% 25% Condition saved 23% 20% 20% 15% 15% 5% The unbalance condition is signaled via Modbus / Fieldbus or a digital output (refer to the complete manual to set the output). i This function is only available if EXCL.CH = NoNE. Use this function only in systems where the load is evenly distributed. 18. Programming Errors MESSAGE preC.

Check the connection of the load cell. Verify the load cell signal is stable, valid and greater than the previously acquired point. Increase the calibration weight. Check the signal from the load cell increases when weight is incremented on the scale. Repeat calibration and verify capacity and division have been correctly set. Transmitter needs to be configurated. Verify the signal from the load cell is not negative. Verify the signal from the load cell is not negative. Check in adC.uv parameter that the signal is stable. If the connection of the cells is with 4 wires, check that the sense jumpers are inserted. Converter failure. Reboot the instrument. Signal anomaly: check the load cells connection. Signal anomaly: check the indicated load cell connection. © Rice Lake Weighing Systems · All Rights Reserved 11 SCT-4X-Ethernet/IP 19.
