Figure 2. IB Tri-Color LED Status Patterns
On power up, the LED flashes the initialization sequence of Off-Green-Red-Yellow-Off indicating that the IB
passed the internal self test with no errors.
If one Display Head is communicating with the IB, the LED will flash: green, pause green, red then yellow, pause
and then repeat the sequence.
If two Display Heads are communicating with the IB, the LED will flash: green twice, pause green, red then yellow,
pause before continually repeating this pattern.
If one or more IB Relay is active, or a delivery is in process, the LED will flash an Off-Yellow-Off sequence until all
the relays are inactive.
If a communication error occurs, the LED will flash Off-Red-Off indicating a problem. Try swapping the Display
Heads as described above in order to locate the problem.
