3) Power failure details (Power red LED flashes twice and OPC (preset) LED flashes)
4) Communication failure details (Power green LED flashes once and OPC (preset) LED flashes)
5) Other failure details (Power green LED flashes twice and OPC (preset) LED flashes)
Error type
OPC LED operation (1 cycle)
Pins are monitor microprocessor pins unless otherwise
specified.
PS_ON
AC_DET failure
Flashes once
H: On
L: Off
AC_DET(72pin: Abnormal (L).
If error is detected during start-up or operation, the power is
turned on again by interrupt handling (instantaneous blackout pro-
cessing).
D_POW
Main 12V failure
Flashes twice
H: On
L: Off
DET_12V(34pin): Abnormal (L). Main 12V is not applied.
If error is detected during start-up or operation, the power is
turned on again by polling.
D_POW
Digital 3.3V
Failure Flashes 3
times
H: On
L: Off
DET_D3V3(36pin): abnormal (L). Digital 3.3V is not applied.
If error is detected during start-up or operation, the power is
turned on again by polling.
PANEL_POW
PNL_12V Failure
Flashes 5 times
H: On
L: Off
DET_DET_PNL12V(35pin): abnormal (L). Panel_Power is not
applied.
Error is started detecteing after Panel Piower - ON, the power is
turned on again by polling.
Error type
OPC LED operation (1 cycle)
Note: Basically, debug print logs are analyzed or
communication logs are analyzed by a bus monitor.
Initial communication
reception
failure Flashes once
H: On
L: Off
Initial communication from the main CPU is not received.
(Request for the monitor model No. is not received.).
→
Communication line failure or main CPU start-up failure.
Start-up confirmation
reception failure
Flashes twice
H: On
L: Off
Start-up reason confirmation from the main CPU cannot be
received. (Startup communication until start-up reason notification
command is not received.)
→
Main CPU start-up failure or monitor microprocessor reception
failure.
Regular
communication failure
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.
Other communication
failure
Flashes 5 times
H: On
L: Off
When a request (PM_REQ=H) is sent from the main microproces-
sor, the request command is not output from the main CPU, etc.
→
Main CPU operation failure or monitor microprocessor recep-
tion failure.
Error type
OPC LED operation (1 cycle)
Note: Pins are monitor microprocessor pins unless otherwise
specified (IC2002).
Monitor temperature
failure
Flashes once
H: On
L: Off
If the panel temperature is 60
°
C or more for 15 seconds or more
in a row, CAUTION appears on the OSD (flashes in red in the
lower right screen).
If the panel temperature is 60
°
C or more for 25 seconds or more
in a row, error standby is activated.
(MONITOR MAX TEMP on page 13/17 of the adjustment process:
Change of temperature failure AD value): Thermistor
Main failure
Flashes 3 times
H: On
L: Off
Main microprocessor detection error (CPU temperature error, etc.)
Details are displayed on page 1/17 of the adjustment process for
the main microprocessor.
