Setting the CAN bus address
The Node No. (Nd.nnn = 1 .. 99) or CAN bus address is set by decade switches S1 und S2. Prior to startup, a
unique Node No. (Nd.nnn = 1 .. 99) or CAN bus address must first be set by the two decade switches (S1, S2)
on all case controllers installed in refrigerated display cases.
The CAN bus address will have been set by the manufacturer on controllers installed in the control panel
(UA 300 D xS), but can subsequently be changed.
So as to avoid confusion, it is recommended to choose the Item ID of the display case as its CAN
bus address. When both decade switches are at zero (giving address 00), the CAN bus is inactive
and the controller is not recognized as a CAN bus station. A different CAN bus address must be as-
signed to each refrigeration point and must be unique within the same system.
