In a filter system consisting of more than one unit, the filter with the lowest address will
be considered as the first unit in the chain. The filter with the highest address will be
considered as the last unit in the chain:
−
In master-slave filter arrangements, it is recommended to assign the lowest
address to the master unit and increment the address by 1 for the next slave etc.
−
In master-master arrangements, the lowest address must be assigned to the
master unit that is considered as the main controlling unit. When the main master
unit is faulty, the master unit with the next lowest address will become the main
controlling unit.

control board has to be set accordingly.
