6.1 Troubleshooting
Problem Possible Cause Solution
The display is blank when the POWER
button is depressed
Discharged battery Recharge the battery; Allow at least four hours charge
Defective battery Replace the battery
Corroded battery or battery contacts Clean the battery contacts
Defective switch or circuit board Requires authorized service
The 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
The 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 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 changes such as moving the scale
from indoors to outdoors
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
The 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
The display toggles between

and

Weight exceeds capacity Reduce weight immediately
Faulty load cell or wiring Check load cell and load cell wiring
The 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
The display toggles between

and

A/D is saturated negative Check the load cell and load cell wiring
Display toggles between

is blinking The battery is low Recharge the battery
Unit turns on, then immediately turns off The battery is low Recharge the battery
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 mechani -
cally noisy crane, increase the filtering or increase the size
of the scale increment d; It is also possible to increase the
motion window; Contact MSI if there is a problem getting
the MSI-4260 IS 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 Func for Total
The weight must be stable Increase filtering for more stability
Auto Total does not work The weight must be stable Wait for the stable annunciator to turn on, or Increase
filtering for more stability
Weight thresholds not reached They must exceed 1% of capacity for autototal to work;
Then you must drop below 0.5% of capacity for additional
weighments to register
