2.5.1 LED Indicators

The FloBoss 407 has three LED indicators to verify operational functionality. Figure 2-10 shows the
location of the indicators and Table 2-3 gives the indicator functions.
When lit, the POWER LED shows that power is applied to the FloBoss 407.
The STATUS LED, located on the processor board, gives a first-level indication of the operation of the
FloBoss 407. After the power is switched on, the STATUS indicator should come on, and remain on to
indicate normal operation. If the STATUS indicator does not remain on, check Table 2-3 for possible
causes.
The PI LED located on the termination board shows the state of the Pulse Input channel. When the
LED is on, the PI channel is active.
