    KP-46WT520/51WS520/57WS520 Self Diagnosis SELF-DIAGNOSTIC FUNCTION Supported model The units in this manual contain a self-diagnostic function. If an error occurs, the STANDBY/TIMER LED will automatically begin to fl ash. The number of times the LED fl ashes translates to a probable source of the problem. A defi nition of the STANDBY/TIMER LED fl ash indicators is listed in the instruction manual for the user’s knowledge and reference.

  • Page 9 KP-46WT520/51WS520/57WS520 Self-Diagnosis Function Operation +B overcurrent (OCP) Occurs when excessive current fl ows through R6812. The increase in voltage across Q6803 causes it to turn on which sends a high signal to the micro. +B overvoltage (OVP) IC6801 detects +B OVP condition and turns on Q6802. This sends a high signal to the micro and also shuts down the AC relay.
