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 the 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 the system, turn off the Fast Ground
Check.
To turn on and off Fast Ground Check:
1. Press the menu button and choose Diagnostics.
2. Enter a level two password.
3. Choose Fast Ground Check.
4. Choose Start to turn on Fast Ground Check or choose
End to turn off Fast Ground Check.
