6. MAINTENANCE
As the Divert Control System is a pure digital system, no special maintenance is needed. The LIGHT TEST
button on the operator panel (Figure 2.50) sends a signal to the microprocessor, and the microprocessor
switches all 11 LED lights on as long as the button is pressed. This way not only the lights but also the proc-
essing system is checked.
To assist the identification of a faulty component, the information flow and the circuit diagrams are given in
Sections 6.1 and 6.2. Also the logic diagrams of Chapter 7 may be of help.
6.1. INFORMATION FLOW
The power and information flow of the total Divert system is shown by Figure 6.10. Additional information
about the cable connections is found in Figures 3.10, 3.11 and 3.12.
