Subdrive50 - Franklin Electric SubDrive15 Manuel Du Propriétaire

SubDrive50

The SubDrive50 is configured at the factory for use with 3.0 hp (2.2 kW) pumps that are
mounted to 5.0 hp (3.7 kW) Franklin Electric three-phase motors. In general, the SubDrive50
will enhance the performance of a 3.0 hp (2.2 kW) pump to a similar or better performance
than a conventional 5.0 hp (3.7 kW) pump of the same flow rating (pump series).
To select the proper 3.0 hp
(2.2 kW) pump, first choose
a 5.0 hp (3.7 kW) curve that
meets the application's head
and flow requirements. Use
the 3.0 hp (2.2 kW) pump in
the same pump series (flow
rating). The SubDrive50 will
adjust the speed of this pump
to produce the performance of
the 5 hp curve.
An EXAMPLE of this is
illustrated in the graph at right.
Please consult the pump
manufacturer's pump curve for
your specific application.
The SubDrive50 can also be set up to run a 5.0 hp (3.7 kW) pump if desired, but the larger
pump will still produce to the 5.0 hp (3.7 kW) curve and may only be operated with a 5.0 hp
(3.7 kW) motor. To operate a different pump size, a DIP switch must be positioned to select
the correct pump rating. Otherwise, the SubDrive50 may trigger erroneous faults.

WARNING
!
Serious or fatal electrical shock may result from contact with internal electrical components.
DO NOT, under any circumstances, attempt to modify DIP switch settings until power has been
removed and 5 minutes have passed for internal voltages to discharge! Power must be removed
for DIP switch setting to take effect.
