Troubleshooting Introduction
The LME7 has an extensive list of fault codes to help clarify the nature of any fault. Section 7-2
describes every fault code in detail and gives guidance on how to correct it.
When a fault occurs, the LME7 will alternate between displaying “Loc” and the fault number.
The fault history is stored in the 700 set of parameters. These are only accessible with an AZL23
remote display or through the ACS410 software. To access the 700 set of parameters on the
AZL23, press and hold the info button until “SEr” is displayed, then let go. The LME7 stores the
last 11 fault codes:
Parameter 701 displays information about the current status of the LME7.
Parameter 702 displays information about the most recent fault.
Parameter 703 displays information about the second most recent fault.
…
Parameter 711 displays information about the 10
th
most recent fault.
Each fault code listed has indexes that provide additional information about the fault:
Index 00 = Fault code
Index 01 = Start number
Index 02 = Phase
Index 03 = Load
Index 01 will display a value of “._._”. This means that the AZL23 display ran out of room to
display the start number. When this happens, hold down the info button to display the value.
An example of how the AZL23 displays a fault code in the fault history is shown below:
