Bailey Infi 90 - Status Signals; Power System Status; Power Distribution to the IEPAS02 System Power Module

DESCRIPTION AND OPERATION
STATUS SIGNALS
I-E96-506B1 2 - 5
STATUS SIGNALS
The block diagram in Figure 2-4 shows the flow of status sig-
nals through the system.
Power System Status
All status lines, AC line, bus voltages, external power inputs,
external customer status inputs, and power module status are
ANDed in the bus monitor module. Bus monitor circuitry
determines if any status line is bad. If any status is bad, the
bus monitor module generates a low-true output signal to the
communication system hardware, which is the bus interface
module for Plant Loop systems, and the network interface
module for INFI-NET systems.
