KV-27HS420/29DRC420/30HS420/32HS420/34HS420/36HS420 +B overcurrent (OCP) Occurs when excessive current fl ows through R5013. The increase in voltage across R5013 causes the output of Q5004 to go high, and this high signal goes to the micro. +B overvoltage (OVP) IC6505 detects +B OVP condition and turns on Q6522. This sends a high signal to the micro and also shuts down the AC relay. V-STOP Occurs when an absence of the vertical defl...
