(g)
The 3-digit display shows code 000 when the BIT switch is pressed and the memory contains no LRU entries, or all entries have been recalled.
(h)
If the BIT switch has been pressed and the BITE panel shows LRU fault, the display goes off 2 minutes |10 seconds after the last BIT switch actuation. Repeated operation again starts the latest recorded fault.
(i)
A memory RESET switch clears all memory contents when pressed.
C.
Control
(1)
Primary 28v dc operating power for the system is supplied by circuit breakers on overhead circuit breaker panel P11 and APU external power panel P34 (Fig. 4). The system is in operation when these circuit breakers are closed.
(2)
The front of the PSEU (Fig. 2) provides switches and indicator lights for checking out sensors, targets, cards and on-ground system trouble shooting. No adjustment is required at either the sensor or the PSEU.
