FAULT INDICATION AND DETECTION
fault
Functions FO F7 I
The fault indication function is composed of the
following three pans:
1. Indication of the present fault.
2. Indication of operating conditions at the time that
the fault took place.
3. Indication of previous faults.
When a fault occurs, the mode will automatically be
switched to the Fault Display Mode.
-- If the fault is a complex one (two or more
neous faults), use the UP or DOWN ARROW keys
to change the 4th data digit and the faults will be
displayed in the and 3rd digits.
-- Inaddition, the operating conditions at thetimeof
the present fault only can be indicated by Func-
tions
through F4.
-- Also, the first fault for the previous three fault trips
can be indicated by F5 through F7.
NOTE: First fault means the first detected fault
when multiple faults occur at the same time.
A more detailed explanation on obtaining fault
information can be found in Section 5 of this
Instruction Book. If the fault will be investigated,
obtain as much fault information as possible before
resetting the
to resume operation. Also
record the date, time, and any information about
the machine operation prior to the fault. This will
help in determining the cause more quickly.
