LED Display Indications
A 5 × 4 matrix of LEDs is used for diagnostics and testing of the unit (see Figure 10). The top
row indicates to which page or toggle (CPU, IO1, IO2, IO3, Page 4, Page 5, Page 6) the LED
panel is set. To advance from one page to another, press the push-button once quickly. The
first depression of the push-button activates the display. Subsequent short depressions of the
push-button advance the display to the next page: CPU > IO1 (I/O Page 1-DI) > IO2 (I/O Page
2-DO) > IO3 (I/O Page 3-AI) > Page 4 (AO) > Page 5 (User Application Controlled) > Page 6
(Hardware Test Controlled). In each page, the LEDs have different functions, as described in
the charts below.
