4 – 21
3) Communication failure details (Power LED flashes 3 times and OPC LED flashe
PANEL_POW
PNL_12V failure
Flashes 5 times
DET_PNL_12V (pin 58) failure (L). Panel power is not
applied.
If error is detected during operation, error standby is activated
by polling.
Main failure
Flashes 7 times
Main microprocessor detection error (FAN error, 1bitAMP
error, etc.)
The details are displayed in "ERROR STANDBY CAUSE" on
page 1 of process A for the main microprocessor.
Error type Notification LED operation (1 cycle)
Basically, communication logs are analyzed by a bus
monitor or debug print logs are analyzed.
Initial communication
reception failure
Flashes once
Initial communication from the main CPU is not received.
(After cancelling the reset, request for the monitor model No.
is not received.)
Communication line failure or main CPU start-up failure.
Time-out setting reception failure
Start-up confirmation reception failure
Flashes twice
Time-out setting and start-up mode change cannot be
received from the main CPU. (Start-up communication until
time-out setting and start-up mode change is not received.)
Main CPU start-up failure or monitor microprocessor's recep-
tion failure.
Regular communication failure
Flashes 3 times
Regular communication that is performed at 1 second inter-
vals in the normal operation is interrupted.
Main CPU operation failure or monitor microprocessor's
reception failure.
Error type Notification LED operation (1 cycle) Pins are microprocessor pins unless otherwise specified.
