The line fault input state is reported as true (logic ‘1’) for a line fault condition (open circuit, short circuit, and no

field supply voltage). The logic state is the majority voted value.

3.2.6. Rack 6: Discrep

Channel Description

1 Discrepancy status outputs 1 to 16 (output 1 is LSB)

2 Discrepancy status outputs 17 to 32 (output 17 is LSB)

3 Discrepancy status outputs 33 to 40 (output 33 is LSB)

Table 10 Rack 6: Discrepancy descriptions

Each of the words reports the discrepancy status of 16 output channels. The corresponding bit within the word is

set to ‘1’ when a discrepancy condition is detected on that output channel’s output state (rack 2).
