Function number “0” is used to display and clear the Fault List. The following
steps explain how to display and clear faults via the LCDU display:
❏ Press the Up or Down Arrow keys to select the desired function number, 0.
The display shows a description of the function on the top line, and the
action that may be performed on the bottom line.
❏ Press the ENT key. If there are no faults in the list, then a no fault message
will be displayed.
If there are faults in the list, then a top of fault list message will be displayed.
❏ Press the Down Arrow key to view the faults in the list. For example:
The top line describes the fault, and the bottom line displays the fault code
along with the PAC block that was executing when the fault occurred. A
PAC block number of “00000” indicates that the fault was declared by the
Kernel software and not by the execution of a PAC block.
The oldest fault is on the top of the list. Therefore, pressing the Down
Arrow key displays a newer fault, and pressing the Up Arrow key displays
an older fault. The end of the list is reached when the Down Arrow key is
pressed enough times and the end of fault list is displayed.
❏ Press the ESC key to return to the function entry mode.
