Figure 33: Entire Machine Faulted with Indicators
When the entire machine is faulted and has turned itself off, the machine will normally take the user
to the Maintenance Screen. The Maintenance screen will also give the user an indication what has
caused the gravity to fault and to shut off. If the PLC doesn’t automatically cause the HMI take you to
the Maintenance Screen, which can sometimes happen if the gravity has faulted multiple times, or
you have accidently navigated away, then you will need to go there yourself. Please refer to the
Section on using the Manual Mode for the gravity on instructions for navigating to the Maintenance
Screen and diagnosing problems with the machine.
VII. Faulting on Power Cycling the Machine
If the gravity has had to be power cycled, or there has been a power outage, when the machine has
powered back up, it will show that all of the functions of the machine controlled by a VFD are faulted.
This is due to the fact that the PLC has temporarily lost communication with the VFDs as the power
was lost, and due to the fact that the VFDs will themselves fault and report a power loss. In this
situation, follow the directions given in the section on operating the machine in Manual Mode and
navigating to the Maintenance Screen to clear the faults.
