Fast ground check
Fast Ground Check is used to quickly check the system for ground
faults. Every 30 seconds, the system checks for ground faults and
reports them by flashing the Ground Fault LED. If you are
troubleshooting ground faults on your system, you may not want to
wait 30 seconds for the ground fault to clear. If the ground fault was
not fixed, you may not want the LED to stay active. By using Fast
Ground Check, you can decrease the system check time to every 4
seconds, meaning that you will be able to troubleshoot your ground
faults much quicker and determine if they have been fixed or not.
Note: Once you solve the ground faults on your system, turn off the
Fast Ground Check.
