The 50A65-143 control continuously monitors its own operation and the operation of the 
system.  If a failure occurs, the LED will indicate a failure code as shown below.  If the 
failure is internal to the control, the light will stay on continuously.  In this case, 
the entire control should be replaced, as the control is not field-repairable. 
 
If the sensed failure is in the system (external to the control), the LED will flash in the 
following flash-pause sequences to indicate failure status (each flash will last 
approximately 0.25 seconds, and each pause will last approximately 2 seconds).
