Subdrive20 - Franklin Electric SubDrive15 Manual De Uso

SubDrive/MonoDrive

SubDrive20

The SubDrive20 is capable of use with 1.0 hp (0.75 kW) pumps that are mounted to 2.0
hp (1.5 kW) Franklin Electric three-phase motors. In general, the SubDrive20 will enhance
the performance of a 1.0 hp (0.75 kW) pump to a similar or better performance than a
conventional 2.0 hp (1.5 kW) pump of the same flow rating (pump series).
To select the proper 1.0 hp
(0.75 kW) pump, first choose
a 2.0 hp (1.5 kW) curve that
meets the application's head
and flow requirements. Use
the 1.0 hp (0.75 kW) pump in
the same pump series (flow
rating). The SubDrive20 will
adjust the speed of this pump
to produce the performance of
the 2.0 hp (1.5 kW) 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 SubDrive20 can also be set up to run a 1.5 hp (1.1 kW) or 2.0 hp (1.5 kW) pump if
desired, but larger pumps will still produce to the 2.0 hp (1.5 kW) curve and may only be
operated with a 2.0 hp (1.5 kW) motor. To operate a different pump size, a DIP switch must
be positioned to select the correct pump rating. Otherwise, the SubDrive20 may trigger
erroneous faults.
See the Basic Set-up section of this manual for DIP switch information and settings.

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.
