Update:
First, Thank You guys for all the help!

Finally, get the elevator going.
Problem is DOR-220 board OUT-1 connector (Bad Connection).
Even fix the connection, the fault E085 still stay and R5SC relay still not picking up.
Need to turn off mainline, set DOC-220 board SW5 dip switch 4 on, then turn on mainline, then the R5SC relay pickup and the fault E085 go away.
Don't know it is the right thing to do. Still looking for a manual.
One thing I do learn from this call is. It is close to impossible to troubleshoot this controller without the right print and manual, most of all you guys help!
Ken :-)
