8.1 Troubleshooting
Problem Possible Cause Solution
Display is blank when Power key is
pressed
Discharged battery Recharge, allow at least four hours charge
Defective battery Replace
Corroded battery or battery contacts Clean contacts
Defective switch or circuit board Requires authorized service
Display does not function properly, front
panel keys do not function normally, or
scale will not turn off
Improperly updated software. Reinstall software
Faulty circuit board Requires authorized service
Loose connectors Requires authorized service
Scale does not respond to weight changes Out of calibration Calibrate
Faulty load cell Replace
Load cell connector Check connector and wires
Display over ranges below 100% capacity Tared weight is added to load to determine overload
point
Return to Gross Weight mode
Zero requires adjustment Rezero the scale
Too much weight has been zeroed Rezero the scale
Display Drifts AZM (Auto0) is turned off Turn AZM on
Rapid temperature changes such as moving the scale
from indoors to outdoors
Wait until the scale temperature has stabilized
Displayed weight shows large error Scale not zeroed before load is lifted Zero the scale with no load attached
lb/kg units causing confusion Select proper units
Requires recalibration Recalibrate
Display reading not stable Excessive vibration in crane system Increase filtering or increase d in cal
Excessive side loading Improve load train symmetry
Load cell faulty Check LC connections
Display toggles between Error and Load Weight exceeds capacity Reduce weight immediately
Faulty load cell or wiring Check LC and LC wiring
Display toggles between Error and A2DLo A/D is saturated negative Check LC and LC wiring
Display toggles between Error and buttn A key is stuck or is being held down Check switches for damage
Ensure that a remote is not transmitting continuously
Optional RF remote does not work Units not mated
See Section 6.2 on page 27 for additional network
setup information
Lo Batt is blinking Battery is low Recharge battery
Unit turns on, then immediately off Battery is low Recharge battery
Weight will not zero System not stable Wait for motion annunciator to turn off
Increase filtering for more stability
Zero out of range LFT units have limited zero range; Reduce the weight
or use tare instead
Weight will not tare or total System is not stable Wait for motion annunciator to turn off, or if in a
mechanically noisy crane, increase the filtering or
reduce the size of the scale increment d ; The motion
window can also be increased. Contact RLWS if there
is a problem getting the MSI-3460 to zero, tare, or total
due to stability issues
Setpoint lights blink Setpoint is enabled and the trigger point has been
reached
Disable setpoints if they are not needed
Manual total does not work A function key is not set to Total Set up Func1 or Func2 for Total
Weight must be stable Increase filtering for more stability
Auto total does not work Weight must be stable Wait for the motion light to go out, or increase filtering
for more stability
Weight thresholds not reached Weight thresholds must exceed 1% of capacity for
autototal to work; Then it must drop below 0.5% of
capacity for additional weighments to register
