List of self-diagnostic
items
If an error is found through the self-diagnostic check of the CPU of
the T3, error messages (and related information) shown in the
tables on the following pages will be recorded in the T3's event
history table. If the error is so severe and continuation of operation
is not possible, the T3 turns OFF all outputs and stops the operation
(error-down).
The iatest 30 error messages and the time and date of the errors
are stored in the event history table. Those error messages can be
displayed on the programmer. (Power ON/OFF is also registered.)
If the T3 has entered to error-down, connect the programmer to the
T3 to confirm the error message in the event history table. The
procedure to display the event history is as follows:
© Connect the CPU module of the T3 and the programmer (T-PDS)
via dedicated cable.
(D Turn ON the power of the programmer (T-PDS). The power of
the T3 must be turned ON in advance,
d) Type "TPDS 0" from the programmer (T-PDS) to start the T-
PDS.
© Press any key to display the main menu of the T-PDS. At this
time, check that "Receive timeout" is not displayed on the
screen.
(D in this state, type the S and E keys to display the event history.
