4.3.2 DIP Switch Settings
The individual 2T sensor must be given a unique address on the CANbus cable run to the associated
Liebert unit. DIP switches are used to give the 2T sensor its unique address. It is important to
confirm that the DIP switches have been set correctly using Table 17. Although it is not required, it
is recommended that the DIP switch sensor number settings correspond to the number of 2T sensors
on the CANbus run. For example, if there are only four 2T sensors used for a particular Liebert CW
unit then the individual DIP switch settings should correspond to address #1, #2, #3 and #4. If the
DIP switches are not set correctly, the control will not operate properly.
