FAN_NG1 FAN1
Shutdown occurs when
the signal is "H."
1 S ∗ 3 times
TEMP2 High temperature at
MTB
Shutdown occurs if any
values equal to or
greater than minimum to
require a shutdown are
detected.
1 S ∗ 3 times
Monitoring conditions
RST4 = H and FAN_ON1 = H
(Monitoring starts 3 sec after the
above conditions are established.)
Operation
If FAN_NG1 (for details on detection logic, see "File of
fan-control specifications") is detected (established) under the
monitoring conditions, a shutdown process starts. A specific
LED flash pattern (blue LED, 10 times) starts.
The next PON operation is valid, and the flag is cleared upon
the next power-on.
RST4 = H
(Monitoring starts 1 sec after the
above conditions are established.)
If any values equal to or greater than minimum to
require a shutdown are detected (established) under
the monitoring conditions, a warning indication will be
displayed for 30 sec, after which a shutdown process
starts. A specific LED flash pattern (blue LED, 11 times)
starts.
The next PON operation is valid, and the flag is cleared
upon the next power-on.
TMP_NG

Shutdown occurs if any
values equal to or

require a shutdown are
detected.

Digital video RST2 = H
If any values equal to or greater than minimum to
require a shutdown is detected (established) under the
monitoring conditions, those changes in status will be
transmitted to the main microcomputer via the UART.
Upon receiving the data, a warning indication will be
displayed for 30 sec, after which a shutdown process
starts. The main microcomputer orders a specific LED
flash pattern (blue LED, 4 times).
The next PON operation is valid, and the flag is cleared
upon the next power-on.
If any values equal to or greater than minimum to
require a shutdown is detected (established) under the
monitoring conditions, those changes in status will be
transmitted to the main microcomputer via the UART.
Upon receiving the data, the main microcomputer
orders a specific LED flash pattern (blue LED, 4 times).
The next PON operation is valid, and the flag is cleared
