APT-P Power Car Fault Panel

Located in the power car is a panel with 64 windows arranged for easy reference in a grid form.

Each window will indicate by two lamps (one for the top half and the other for the bottom half of the display) a specific fault condition

the fault has occurred and persists
the fault has occurred and disappeared

The panel displays can all be tested by a test switch and the memory or record display part can be reset by the second switch.
