Hello, Since SF LED is RED, it indicates BUS fault. Hence I suggest you to check MCP & other components address. You need to refer documents submitted by OEM & check DIP switches e.g. on MCP etc. etc. Moreover please check 611D drive LED status. You can disconnect data/bus cable which is between CCU & 611D drive one by one & switch ON power. Check if SF LED on 7 segment display lits or is OFF. A faulty drive could also trigger SF fault. Please refer this link which will display FAQs on 120202 error, may help you to understand more. HTH |
