The 10 output LEDs (D8-D17) pictured correspond to
the output triacs, which engage power terminals (T1-

When the output triac switches on and engages a
power terminal, the corresponding output LED lights
up. When the power is disengaged, the LED is not lit.
The output LEDs can be used to troubleshoot problems
with the components supplied by the power terminals.
