MONITOR_ERR_CAUSE list
Error type OPC LED operation (1 cycle)
Pins are monitor microprocessor pins unless otherwise
specified.
DET_15V error
Flashes once H: On
L: Off
DET_15V (34pin) error (L). UR13V is not applied.
If error is detected during operation, error standby is activated by
polling.
DET_D3V3 error
Flashes twice H: On
L: Off
DET_D3V3 (36pin) error (L). D3.3V is not applied.
If error is detected during operation, error standby is activated by
polling.
DET_5V error
Flashes 3 times H: On
L: Off
DET_5V (33pin) error (L). 5V is not applied.
If error is detected during operation, error standby is activated by
polling.
PNL_12V error
Flashes 5 times H: On
L: Off
DET_PNL_12V (35pin) error (L). Panel power is not applied.
If error is detected during operation, error standby is activated by
polling.
Main error
Flashes 7 times H: On
L: Off
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.
TCON ROM error
Flashes 8 times H: On
L: Off
LCD controller ROM error
It is notified by communication from the main CPU.
Error type OPC LED operation (1 cycle)
Basically, log analysis of debug print statements or com-
munication log analysis by a bus monitor is performed.
Initial communication reception error
Flashes once H: On
L: Off
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 reception error
Start-up confirmation reception error
Flashes twice H: On
L: Off
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 error
Flashes 3 times H: On
L: Off
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.
