3. Select
the desired operating mode (pressure or
flow), u
sing the pull-down menu.
In pressure mode, the motor will adjust the
pump speed to maintain the fluid pressure
percentage set on Setup Screen 2. If the flow
limit is reached before the target pressure, the
unit will stop driving to the pressure (if set as
an alarm).
In flow mode, the motor will maintain a
constant speed to maintain the target flow rate
set on Setup Screen 3, regardless of the fluid
pressure, up to the pump’s maximum working
pressure.

4. If the system is equipped with a back pressure
regulator (BPR), set the target air pressure to the
BPR from 0 to 100 percent (approximately 1 to
100 psi). Leave the field set to 000 for a system
with no BPR. See manual 332142 for information
on the BPR control kit.
