• Operations : When a microcomputer detected abnormality, it turns the power supply OFF.
• LED display : Blinking in green
How to release shutdown
If the Power key on the remote control unit is pressed, the shutdown
status is released, and the unit will be turned on. (It is not necessary
to press the MAIN POWER button to turn off the unit.)
Example: How the LED blinks when DIGITAL-IIC communications fail
• Operations : In an emergency, the protection circuits are activated, and the power is turned off.
• LED display : Blinking in red
Note: If more than two protection circuits are activated at almost the same time, the LED indicates this by its
blinking-pattern.
Example: How the LED blinks for the first power-down (Y-DC/DC CONVERTER) and the second power-down (Y DRIVE)
