dependably, even as water demand changes. For example,
a small demand on the system, such as a kitchen faucet,
results in the motor/pump running at a relatively low speed.
As greater demands are placed on the water system, such as
opening additional faucets or using appliances, the motor/
pump speed increases accordingly to maintain the desired sys-
tem pressure.
MOTOR SOFT START
Whenever the Artesian Drive detects that water is being used,
the controller always “ramps up” the motor speed at the
same time as gradually increasing voltage, resulting in a cool-
er running motor and lower in-rush current compared to a
motor being used on conventional water systems. If the water
demand is very low, the system may cycle on and off at very
low speeds, but due to the drive’s soft-start feature and pres-
sure switch’s dependable design, this will not harm the motor
or the pressure sensor.
SYSTEM DIAGNOSTICS
In addition to regulating system pressure and accurately
controlling motor operation, the Artesian Drive continuously
scans the system and can detect a variety of abnormal condi-
tions. If there is elevated risk of damage to a part of the sys-
tem, the drive will protect the system and display a code for
the fault. If possible, the drive will try to restart itself when
the fault condition passes.
PUMP SIZING – ARTESIAN DRIVE (CENTRIFUGAL)
The Artesian Drive is configured at the factory for use with
standard 3-phase motors and pumps.
NOTE: The Artesian Drives are factory programmed to F&W
pumps to provide optimum performance and motor protec-
tion. The Artesian Drive can be used with other pumps, but
the maximum motor amperage needs to be compared to the
factory programmed current value (refer to the Specifications
section under the appropriate model). If the maximum motor
current varies more than 5% from the programmed value,
the motor current value in the drive needs to be changed
for motor protection and optimum performance. For details
on how to change this value in the drive, please contact
Technical Support at 1-800-345-9422.
!
The motor rated current must be set
correctly to avoid a risk of fire in the
event of a motor overload.
DRIVE CONFIGURATION
When sized correctly, the Artesian Drive systems are ready to
go right out of the box and need no configuration. Under
certain circumstances there are several programming param-
eters that can be changed to accommodate non standard
systems. For further information to change these parameters,
please call Technical Support at 1-800-345-9422
!
Serious or fatal electrical shock may result
from contact with internal electrical components. DO NOT,
under any circumstances, attempt to modify connections to
the drive until power has been removed and 10 minutes have
passed for internal voltages to discharge!
UNDERLOAD SENSITIVITY
The Artesian Drive controller is configured at the factory
to ensure detection of Underload faults in a wide variety
of pumping applications including dead head and run dry
conditions. In very rare cases (as with certain pumps in shal-
low wells) this trip level may result in nuisance faults. If the
pump is installed in a shallow well, activate the controller
and observe system behavior. Once the controller begins to
regulate pressure, check operation at several flow rates to
make sure the default sensitivity does not induce nuisance
Underload trips. If it becomes necessary to desensitize the
Underload trip level, please call of Technical Support at 1-800-
345-9422 for further details.

Serious or fatal electrical shock may result
from contact with internal electrical components. DO NOT,
under any circumstances, attempt to modify connections to
the drive until power has been removed and 10 minutes have
passed for internal voltages to discharge!
Before Getting Started
!
Serious or fatal electrical shock may result
from failure to connect the ground terminal to the motor,
Artesian Drive controller, metal plumbing, or other metal
near the motor or cable, using wire no smaller than motor
cable wires. To minimize risk of electrical shock, disconnect
power before working on or around the Artesian Drive
system. CAPACITORS INSIDE THE ARTESIAN DRIVE CONTROLLER
CAN STILL HOLD LETHAL VOLTAGE EVEN AFTER POWER HAS
BEEN DISCONNECTED. ALLOW 10 MINUTES FOR DANGEROUS
INTERNAL VOLTAGE TO DISCHARGE BEFORE REMOVING
ARTESIAN DRIVE COVER.
!
Do not use motor or system in swimming
areas.
IMPORTANT: This equipment should be installed by technically
qualified personnel. Failure to install it in compliance
with national and local electrical codes and within F&W
recommendations may result in electrical shock hazard, fire
hazard, unsatisfactory performance, or equipment failure.
Installation information is available directly from F&W at our
toll-free number 1-800-345-9422.
Use Artesian Drive only with properly sized
three phase motors. Use of this unit with improperly sized
motors may result in damage to both motor and electronics.
Controller Location Selection
!
The drive’s enclosure is NEMA 1 rated
and is intended for indoor use only. It
should be mounted in a location that provides protection
from water spray/drips and only be accessed by trained and
authorized personnel.
The Artesian Drive controller is intended for operation in
ambient temperatures up to 104°F (40°C) at 230 VAC input.
The following recommendations will help in selection of the
proper location of the Artesian Drive unit:
1. A tank tee is recommended for mounting the tank, pressure
sensor, pressure gauge, and pressure relief valve at one
junction. If a tank tee is not used, the pressure sensor should
be located within 6 feet (1.8 meters) downstream of the
pressure tank to minimize pressure fluctuations.
NOTE: There should be no elbows between the tank and pres-
sure sensor and the tank should be between the the pump
and pressure sensor.
2. The unit should be mounted on a sturdy supporting
structure such as a wall or supporting post. Please take into
account the weight of the unit (refer to the Specifications
section under the appropriate model).
3. The electronics inside the Artesian Drive are air-cooled. As a
result, there should be at least 4 inches of clearance on each
side and below the unit to allow room for air flow.
