detected Remains on if normal status is restored.
• Turn on if a momentary power interruption of less than
OFF : AC/DC DOWN 20ms occurred during use of the AC power supply
not detected module, and reset by turning power off to on.
ON : AC/DC DOWN
• Turn on if a momentary power interruption of less than
detected
10ms occurred during use of the DC power supply
module, and reset by turning power off to on.
• Turned on when the voltage of the external battery
reduces to less than specified value. Turn off when the
OFF : Normal voltage of the external battery becomes normal.
ON : Battery low • Synchronizes with "BAT. LED"
• Check the voltage of the external battery, only when it is
set with "external battery use" by system setting.
• Turn on when the voltage of the external battery reduces
to less than specified value. Remains on if normal status is
OFF : Normal restored.
ON : Battery low • Synchronizes with "BAT. LED"
• Check the voltage of the external battery, only when it is
set with "external battery use" by system setting.
OFF : No error • Turn on when error is found as a result of self-diagnosis.
ON : Error Remains on if normal status is restored.
OFF : No error • Turn on when error is found as a result of diagnosis.

OFF ON : Error reset • A release of the error is executed.
• Turn on when a "watchdog timer error" is detected by the
Motion CPU self-diagnosis function.
When the Motion CPU detects a WDT error, it executes
