The green LED is powered by the on-board +5V supply and indicates a
“power on” condition when illuminated.
R e d
The red LED is controlled by the fault protection circuitry on the INT-462H.
If the red LED is illuminated, remove power and check for a system fault.
Verify that the current adjust resistor is in place and the correct value. A fault
condition can only be cleared by cycling power or toggling the RESET input
at Pin 11 of the terminal strip.
