• Error messages are cleared when the condition is remedied. Troubleshooting • RUN mode errors are suppressed during PROGRAM mode, zero or span calibration. • Zero and span errors are cleared when zero or span is initiated. Errors that happen during the calibration require re-starting the procedure. • Program errors are cleared when any key is pressed. • The messages E101 through E104 can be turned off (P949). • The load cell errors are detected by certain conditions where it is apparent that the load cell is not functioning or incorrectly wired. It is not a conclusive test, since even with incorrect wiring, the resulting input from the load cell may be within a valid range.
Page 66 Milltronics BW100 - INSTRUCTION MANUAL 7ML19985DJ01 message diagnosis action E101 (run) load cell A mV reading is out of range error will appear if:
• mV signal from load cell A or B is out of the 0-50 mV range • the mV signal from load cell A or B is less than the zero calibration mV level minus one half the span mV level • A or B mV is greater than 4 times the span mV value check load cell mV signal and ensure that it is within range check wiring E102 (run) load cell B mV reading is out of range E103 (run) combined mV signal from load cell A and B is out of range error will appear if the com- bined mV signal from load cell A and B is too low check both load cell signals and ensure that they are greater than 0 mV check wiring E104 (run) faulty memory location found cycle power and perform mem- ory test (P901) if error reappears, the BW 100 must be repaired or replaced.
