ABB PQFM Instruction Manual page 19

In multi-unit filters consisting of more than one master, all the master units have a PQF-
Manager. However, only the PQF-Manager that is connected to the master unit which
has the overall control will be active. The PQF-Manager installed on the units operating
as "slaves" are capable of displaying the relevant information about that specific unit
only. Certain parameters which are specific to that unit (e.g. related to temperature
probes) can be set or changed locally using the PQF-Manager installed on that unit. The
PQF-Manager on the master unit has a "unit selection"
to select the unit number which he wants to consult. The data then displayed on the
master PQF-Manager is specific to that particular unit number. This unit selection
button is "deactivated" on the slave Managers.
