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.
Basic Setup (DIP Switches)
For basic set-up, DIP SW1 Position 1 (FE Connect switch) must be in the "OFF" (down)
position for DIP switch, Pressure Setpoint Potentiometer, and Underload Potentiometer
settings to be recognized.
Motor Type Selection (DIP SW1 - Position 2)
SubDrives have the ability to perform as MonoDrives when needed (SubDrive15 can
be set as a MonoDrive. SubDrive20, SubDrive30, and SubDrive50 units can be set as a
MonoDrive or MonoDriveXT). If you wish to operate a single-phase motor with a SubDrive
unit, ensure that DIP SW1 Position 2 is in the "ON" (up) position This is indicated by
"MD" printed above DIP SW1 Position 2 on the black shield. If using a SubDrive with a
three-phase motor, ensure DIP SW1 Position 2 is in the "OFF" (down) position, which is
indicated by "SD" printed below DIP SW1 Position 2 on the black shield (this is the default
setting for SubDrive units).
NOTE: When operating a SubDrive as a MonoDrive, the MonoDrive pump and motor
specifications on Page 5 apply.
Motor / Pump Size (DIP SW2 and DIP SW3 - Positions 1-6)
The SubDrive/MonoDrive can be configured to operate by setting only two (2) DIP switches;
one (1) for the motor size and one (2) for the pump size. The DIP switches are located on
the top of the User Interface board as shown in the figure below.
NOTE: When operating a SubDrive as a MonoDrive, the MonoDrive pump and motor
specifications on page 5 apply.
Select the one (1) DIP switch from SW2 that corresponds to the motor hp being used
and one (1) DIP switch from SW3 that corresponds to the pump hp being used. The
corresponding hp values are printed above the SW2 and SW3 diagrams on the black
shield. Selecting none or more than one switch in either SW2 or SW3 will result in an
Invalid DIP Switch Fault indicated by F24 on the display.
