Gp 6.3 Input/Output Leds - Challenge CMT-130TC Service Manual

GP 6.3 Input/Output LEDs

The main PWB has LED indicators for each in-
put and output. An input or output LED lights up
whenever the corresponding input or output is
on. This can be helpful for troubleshooting input
and output devices as well as the main PWB.
Certain status indicator RAPs refer to these.
The main PWB is located on the electrical panel
as shown in Figure 6-5. The location of the
LEDs are shown in Figure 6-6.
