Diagnostic LED Panel

Use the matrix display on the CPU Module for diagnostics and testing of Single Cable
Module (See Figure 3-13). The top row indicates which module (CPU, M1, M2 or M3) the
LED panel is set to display and the blue numerals on the LED panel are the I/O
indications.
Press the pushbutton once, momentarily, to activate the LED panel. Every consecutive
momentary depression of the pushbutton will advance the display to the next module, in
the following order: CPU, M1 (I/O Module 1), M2 (I/O Module 2), and M3 (I/O Module 3).
The next depression of the pushbutton will return the display to the CPU. Verify that the
relevant LED is lit.
For example; Figure 3-13 Single Cable Module LED Display shows indications from the
module in slot number 3 (M3). LED number 5 is on, indicating that at least one of the
connected RTUs is turned on.
Table 3-8 specifies the LED indications for the Single Cable Module.
