Pins are monitor microprocessor pins unless otherwise
DET_15V (34pin). UR10V or A9V is not applied.
If error is detected during operation, error standby is activated by
polling.
DET_D3V3 (36pin) error (L). D3.3V is not applied.
If error is detected during operation, error standby is activated by
polling.
DET_5V (33pin) error (L). D5V or A5V is not applied.
If error is detected during operation, error standby is activated by
polling.
DET_PNL_12V (35pin) error (L). Panel power is not applied.
If error is detected during operation, error standby is activated by
polling.
Main microprocessor detection error (AMP error, etc.)
Details are displayed in "ERROR STANDBY CAUSE" on page 1 of
the process A for the main microprocessor.
LCD controller ROM error
It is notified by communication from the main CPU.
Basically, log analysis of debug print statements or com-
munication log analysis by a bus monitor is performed.
Initial communication from the main CPU is not received.
(Request for the monitor model No. is not received after cancel-
ing the reset.)
→ Communication line error or main CPU start-up failure.
Time-out setting and start-up mode change from the main CPU
is not received. (Start-up communication of time-out setting and
start-up mode change is not received.)
→ Main CPU start-up failure or monitor microprocessor recep-
tion failure.
Regular communication that is performed at 1 second intervals
in the normal operation is interrupted.
→ Main CPU operation failure or monitor microprocessor recep-
tion failure.
