7.1 Troubleshooting
Problem Possible Cause Solution
Display is blank when the POWER button is
depressed
Discharged batteries Replace batteries
Defective battery Replace batteries
Corroded battery or battery contacts Clean the battery contacts
Defective switch or circuit board
Requires authorized service
Display does not function properly, the front
panel button does not function normally or
the scale will not turn off
Improperly updated software Reinstall the software
Faulty circuit board Requires authorized service
Loose connectors Requires authorized service
Scale does not respond to weight changes Out of calibration Calibrate the unit
Faulty load cell Replace the load cell
Load cell connector Check the connector and wires
The 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
The display drifts AZM (Auto0) is turned off Turn AZM on
Rapid temperature change,
moving scale outdoors from indoors
Wait until the scale temperature has stabilized
The displayed weight shows a large error Scale not zeroed before load is lifted Zero the scale with no load attached
lb/kg units causing confusion Select the proper units
Requires recalibration Recalibrate the unit
Display reading is 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 the load cell connections
Display toggles between

and

Weight exceeds capacity Reduce weight immediately
Faulty load cell or wiring Check load cell and load cell wiring
Display toggles between

and

Weight in below the zero range If the scale is in compression, remove the source
Calibration faulty Recalibrate
Faulty load cell or wiring Check the load cell connections
Display toggles between

and

A/D is saturated negative Check the load cell and load cell wiring
Display toggles between

and

A key is stuck or is being held down Check switches for damage
Ensure that a remote is not transmitting continuously
RF remote device does not work Units are not paired Contact Rice Lake Weighing Systems
Unit turns on then immediately turns off Batteries are low Replace batteries
Weight will not zero The system not stable The stable annunciator must turn on for Zero to function;
Increase the filtering for more stability
Increase the filtering for more stability
Zero is out of range Legal for Trade units have limited zero range;
Reduce the weight or use Tare instead
The weight will not Zero, Tare or Total The system is not stable Wait for Stable annunciator to turn on, or if in a mechanically noisy
crane, increase the filtering or increase the size of the scale increment
‘d’; It is also possible to increase the motion window; Contact Rice
Lake Weighing Systems if you have a problem getting the MSI-4260M
to zero, tare, or total due to stability issues
Setpoint lights blink Setpoint is enabled and the trigger
point has been reached
Disable set points 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”
The weight must be stable Increase filtering for more stability
Auto Total does not work The weight must be stable Wait for stability annunciator to turn on, or increase filtering
Weight thresholds not reached Capacity must exceed 1% for autototal to work; Capacity must drop
below 0.5% of capacity for additional weighments to register
