Pressure Input Selection (DIP SW1 — Position 5)
Ensure that the drive is configured for the type of pressure transducer or sensor being used:
•
If using a 4-20 mA 100 PSI pressure transducer (included), DIP SW1 Position 5 must be in the XDCR
(down) position.
•
If using a standard pressure sensor, DIP SW1 Position 5 must be in the PS (up) position.
Adjusting Pressure Setting
IMPORTANT: Monitor pressure gauge during initial startup to ensure system does
not over-pressurize.
P P r r e e s s s s u u r r e e T T r r a a n n s s d d u u c c e e r r : : When using the 100 PSI pressure transducer, the desired
system pressure is set by using the pressure setpoint adjustment knob. The knob is
factory set to 50 PSI and is adjustable from 5 to 95 PSI in 5 PSI increments. Refer
to the indicator lines surrounding the switch and the corresponding legend printed
on the shield when setting the desired pressure setpoint.
The pressure setpoint must be adjusted with the drive powered OFF. When the
drive is powered ON, the screen will display the active system pressure.
NOTE: This knob is only compatible with the default 4-20 mA 100 PSI pressure transducer. If using a
pressure transducer with a different range, DIP Switch 1 – Position 1 must be in the O O N N (up) position and
the Pressure Transducer Type, Pressure Transducer Range, and Pressure Setpoint parameters must be
configured using the mobile app. Refer to
P P r r e e s s s s u u r r e e S S e e n n s s o o r r : : The sensor (1) is preset at the factory to 50 psi (3.4 bar), but
can be adjusted by the installer using the following procedure:
•
Remove the rubber end-cap.
•
Using a 7/32" Allen-wrench (2), turn the adjusting screw clockwise to increase
pressure and counter-clockwise to decrease pressure. The adjustment range is
between 25 and 80 psi (1.7 and 5.5 bar).
NOTE: 1/4 turn = approximately 3 psi (0.2 bar).
•
Replace the rubber end cap.
•
Cover the pressure sensor terminals with the rubber boot provided. Do not
place boot in direct sunlight.
IMPORTANT: Do not exceed the mechanical stop on the pressure sensor.
When the drive is powered ON, the display will show motor speed rather than the
active system pressure.
