7.2 Twin or Triple Systems
The Magnum Electronic Controls may be configured as
a twin parallel or triple parallel system which assures,
through an electrical interlock built into the 962
controls, that only one unit will regenerate at a time.
Compared to a single system, the parallel system also
provides twice the available service flow rate when
both units are on line in a twin system and three times
the available service flow rate when all three units are
on line in a triple system. When the capacity of one of
the units in a parallel system has been exhausted, the
962 control takes the unit “off-line”, regenerates the
unit, then returns the unit to “on-line” status while
preventing the other units in the system from
regeneration through an internal electrical lockout.
