8.1.1 Service Counters
The MSI-3460 maintains two service counters for safety.
• The first counter counts the number of times the scale has been overloaded.
• The second counter counts lifts above 25% of capacity.
These counters serve to warn the user to inspect the load train after a number of
overloads, also when there is a chance of fatigue failure. The power up routine will be
interrupted when the lift counter exceeds 16383 lifts or the overload counter exceeds
1023 overloads. If the screen displays LFCNT when unit is powered on :
1. Push TARE to display the 25% lift counter.
2. Push TARE again to see the overload lift counter.
3. Push the ZERO key to acknowledge the warning and return to standard scale
operation.
WARNING
Note
The power up warning message won't appear again for another 16383
lifts ( or 1023 overloads).
To access the service counters:
4. Program a user function key to be TEST (see function key setup).
5. Press TEST (USER).
6. Within two seconds of pressing the TEST (USER) key, press TARE.
7. The display flashes “LFCnt” (for Lift Counter) followed by the number of times
the weight has exceeded 25% of capacity.
8. Press TEST (USER). The display flashes “OLCnt” (for Overload Counter)
followed by the number of times the weight has exceeded capacity.
9. Press TEST (USER). The display flashes the C-Cal value.
10.Press TEST (USER). Returns to standard weighing mode.
Only a MSI factory representative can reset the service counters,
as these are important safety warning features. Depending on
the circumstances, a thorough load train inspection might be
necessary to ensure user safety.
