A cable fault or deteriorating transformer to the red can cause an excess
current to flow. The Microsense controller registers this as a conflict in
the fault log and this excess current will cause the problems you are
experiencing.
Alternately, the controller lamp monitoring may have been learned with -1
red and when the red failure occured 2 reds were seen unlit.
