LED Indicators
There are four LED indicators located inside the converter in the upper right
hand corner of the 300-SJB2 Junction Board (see Figure 3-9 in Section 3).
The indicators are numbered D5, D6, D7, and D8. They serve as status
indicators for digital outputs on terminal block X7. These visual status
indicators are helpful during start up for diagnosing and resolving problems
(see the following table).
