(2) Trouble mode process

The machine can be operated under some conditions.
Operations except for the trouble mode are enabled (READY). For the
modes which cannot be operated, only setting is enabled and a mes-
sage is given to show the operations are disabled. (NOT READY in this
case)
(Display)
When a trouble occurs, a dialog is shown. In the mode where the oper-
ation is enabled, the OK button is added to the message. In the mode
where the operation is disabled, the OK button is not shown and the
display is kept until the trouble is canceled.
B. Power ON trouble detection sequence.
• When the power is turned ON, if H3, H4, H5, U1, U2, PF, L4-31, F3-12/22, or U6 (LCC-related sub code 09 only) is saved, a trouble code is imme-
diately displayed. E7 (50, 55, 56, 57, 60, 65, 66, 67) trouble is not saved.

H3, H4, U1, U2, U6 PF trouble check
Trouble check is made in each block when initializing
and data are sent to the ICU.
H3, H4, H5, L4-31, F3-12/22: Saved in the PCU.
U1: Saved in the ICU.
U2: Saved in each block.
PF: Saved in the ICU.

(3) Writing to the trouble memory

In case of a same trouble in this machine, selection is made with the
simulation to write into the trouble memory or not. If this simulation is
set, any trouble is written into the trouble memory unconditionally.
(SIMULATION. 26-35)
0: A same trouble as the previous one is not written. (Default)
1: Any trouble is written into the trouble memory unconditionally.
Communication of trouble status
[Trouble data ID] [Trouble code]
Trouble cancel command

communicated.
Each block
When the power is turned on,
check is made in each block.
