7.1.1 Error Codes
The ScaleCore processor that is the heart of the MSI-7300 Dyna-Link 2 detects errors and generates error codes to aid in
troubleshooting.
Table 7-2. Error Codes
LcOFF LC Disabled A load cell was not enabled
2CAL In Cal The system is in calibration mode. Do not send commands unrelated to calibration.
unCAL Not Calibrated System has not been calibrated.

UnLd
Underload Tension/Weight is more than 20% negative
Load cell damaged or disconnected
7.2 Service Counters
The Dyna-Link 2 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 warn the user to inspect the load train after a number of overloads and 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

when unit is powered on:
Note
1. Press the
TARE F-key
key to display the 25% lift counter.
2. Press
TARE F-key
key again to see the overload lift counter.
3. Press to acknowledge the warning and return to standard scale operation.
The warning message during power up will not display again for another 16383 lifts (or 1023 overloads).
To access the service counters:
1. Program an
F-key
to

. See Section 4.2 on page 9.
2. Press
F-TEST .
3. Press . Test sequence including the following will begin.
• Lift Counter (

) – followed by number of lifts where the weight exceeded capacity by more than 25%.
• Overload Counter (

) – followed by number of lifts where the weight exceeded capacity.
• C-CAL value
Once the test is complete, the Dyna-Link 2 returns to the weigh mode.
Note
Press
F2
to stop the sequence, use
F1
and
F2
to view parameters. Press to return to
weigh mode.
The Service Counters are safety warning features, only Rice Lake Technicians can reset these.
WARNING
In some circumstances, a thorough load train inspection may be necessary to ensure user safety.
Reference the Crane Scale Safety and Periodic Maintenance manual for proper loading techniques to
improve the safety and longevity of the crane scale, available online and is included on the CD shipped with the scale.
Manual total does not
work A function key is not set to “Total” Set up Func1 or Func2 for Total
Tension must be stable Increase filtering for more stability
Auto total does not work Tension must be stable Wait for standstill annunciator to turn on, or increase
filtering for more stability
Tension thresholds not reached The tension threshold must exceed 1% of capacity for
autototal to work, and then, must drop below 0.5% of
capacity for additional weighments to register.
