5.8 Fault memory menu
This menu records the last 20 faults on the machine and the associated values measured at the time the faults occurred.
To enter the FAULT MEMORY menu, use the + or – buttons to position the cursor on 7 then press OK.
The list of faults appears on the display. The top left of the screen flashes first, followed by the line being queried. Press the + or – buttons to
scroll through the faults.
Accessing the fault memory.
Below is a list partial of fault memory messages for all fault types (main circuit fault, main unit fault, temporary fault).
Important: Faults can be manually reset from this menu only.
