Below is the behavior of the FAULT LED when a FAULT is detected:
When a FAULT is present, and the motor is not running,
1.
only the FAULT LED and power LED will illuminate.
2. When a FAULT is present, and the motor is running, then
the FAULT LED will illuminate. During the FAULT condition,
the bar graph LEDs on the interface will turn OFF. However,
the power LED, start LED & active STEP LED will remain
illuminated.
3. When a FAULT is present and the FAULT LED is illuminated,
only the STOP key will function. The remaining buttons
become disabled.
4. When the FAULT LED is continuously ON (i.e. not blinking), a
FAULT is present in the controller. When the FAULT LED is
blinking every one (1) second, a FAULT is present in the user
interface.
5. When the FAULT has cleared, the FAULT LED will turn OFF.
6. Once the FAULT is cleared, if the V-Green 165 was previously
running, it will automatically resume running the normal
schedule.
Please see Section 14 for troubleshooting issues and their resolutions.
