The multicolored PROCESS LED is used to indicate the current state of
the processes being controlled by the FP-3000. When a PID function block
on the FP-3000 module is in initialization, the light flashes green. When all
the executing PID blocks on the FP-3000 are in Target mode, the light
remains lit solid green. Any active alarm of priority greater than eight
results in the light being lit red. For more information on PID blocks, refer
to the section

Table 2-1 describes the NETWORK LED states.
The red STATUS LED is lit when the FP-3000 detects a failure. If
STATUS is not lit, the FP-3000 has not detected a failure. The FP-3000
indicates specific error conditions by flashing STATUS a specific number
of times. Table 2-2 describes the STATUS LED flashing sequences and the
corresponding error conditions.
