• There are two types of rotary switch setting available: setting addresses 1 to 9 and over 10, and setting branch
numbers.
a) How to set addresses
Example: If Address is "3", SWU2 (for over 10) remains at "0", and match SWU1 (for 1 to 9) to "3".
b) How to set branch numbers SWU3 (only for R2 seres)
Branch number matches the BC controller branch number. If two branches are used, SWU3 should be set to a
smaller branch number. For other than R2 series, remain SWU3 as "0".
