Issue:In SoMove the Fault history shows "Hour of Fault".
Product line:ATS48, Altistart 48
Environment:all models
Cause:Troubleshooting
Resolution:
The time is based on the ATS48 operating time (run time), not a realtime clock. Run time can be found in the Monitoring menu, parameter rnt.
Since this follows Operating Time, if the Run time is reset using the rPr parameter under the drC menu, then the fault history Hour of Fault will match the updated run time. Replacing the control board will also cause the Run time to reset to 0.
Note: To reach the maximum run time of 65535 hours, the unit would have to run for almost 7.5 years at continuous operation, 24hrs a day, 7 days a week.
