Why does the red LED come on my Drews HCC 11 Control Unit?

  Jasmine BrownAug 3, 2025
  The red LED might illuminate due to several reasons: * There could be an interruption in the circuit or load, so you should check those. * There might be a partial load condition; inspect the load. * A fuse might have blown; check and replace it if necessary. * The SSR might be malfunctioning; check the SSR. * The current could be outside the monitoring window, so adjust the current accordingly.
