Descriptions and Features

The F&W Artesian Drive is a dependable water system Variable Frequency Drive (VFD) that uses custom programming to enhance the performance of standard centrifugal pumps. When applied correctly to three phase motor driven pumps, the Artesian Drive eliminates pressure cycling associated with conventional pressure switch controlled water pumping systems and provides a constant output pressure.

KEY FEATURES OF THE ARTESIAN DRIVE INCLUDE:

• Constant water pressure with a wide range of settings (30-80 psi) (Note: The maximum obtainable system pressure is limited by the performance of the pump installed)

• Smaller pressure tank can be used

• Fits the pump to the application – pump speed is con-

trolled to provide the optimum performance without overloading the motor

• Flexibility – you can use this unit with standard off-theshelf pumps and 3-Phase motors

• No in-rush (power-on transient) current

• Low motor start-up current (soft-starting)

• Active Power Factor Correction minimizes input RMS cur-

rent

• Protection features

- Dry run conditions – using intelligent load monitoring (see Page 8)

- Bound pump – with auto-reversing torque

- High voltage / lightning surge

- Low line voltage

- Short circuit

Constant Pressure

The F&W Artesian Drive provides consistent pressure regulation using custom programming to run a standard motor and pump according to the pressure demands indicated by a heavy duty pressure switch. By adjusting the motor/pump speed, the Artesian Drive can deliver consistent pressure

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 system 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 cooler 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 pressure 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 conditions. If there is elevated risk of damage to a part of the system, 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 protection. 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 parameters 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

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!

Serious or fatal electrical shock may result

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 shallow 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

95 North Oak St. • Kendallville, IN 46755 • 1-800-345-9422

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 1-800345-9422 for further details.

Serious or fatal electrical shock may result

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 pressure 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.

Wiring Connections

Serious or fatal electrical shock may result from failure to connect the motor, the Artesian Drive, metal plumbing and all other metal near the motor, or cable to the power supply ground terminal, using wire no smaller than motor cable wires. To reduce risk of electrical shock, disconnect power before working on or around the water system.

To avoid a fire hazard and maintain validity of the UL listing, torque the power terminal screws to 12 lb.-in. (1.4 N-m).

Do not use motor or system in swimming areas.

BEFORE BEGINNING WIRING

1. Verify that the power has been shut off at the main breaker.

2. Verify that the dedicated branch circuit for the Artesian

Drive is equipped with a properly-sized circuit breaker. Refer to Table 2 (Page 8) for minimum breaker size.

3. Insert the provided strain relief into the mounting holes on

the bottom of the enclosure. (Strain relief fittings are not supplied for the motor supply cable and power supply leads on AD150145).

4. Remove the Artesian Drive cover. Line up the alignment

notches and slip the memory stick into the slot on the front of the controller. Note: Do not force the stick into place; it should slip into the slot and protrude about 3/4” from the face of the controller with the cover off when fully seated.

5. Feed the motor supply cable and 230 VAC power leads through the bottom right and left strain reliefs respectively. Connect the motor ground and power supply ground wires the terminal block marked GND and PE respectively.

Because of the leakage current produced by the internal filtering, permanent fixed ground connections must be made using two independent conductors each with a cross-section equal to or exceeding that of the supply conductors. The drive is provided with two ground terminals marked PE to facilitate this.

6. Connect motor supply leads to terminal block positions

marked U, V and W (right hand side). Connect power leads to terminals marked L1 and L3 (left hand side).

Note: For correct motor rotation and pump performance on F&W manufactured motors, leads 1-7, 2-8 & 3-9 on the motor should be connected to U, V & W respectively. Three phase motors from other manufactures may require that connection U & V be switched at the drive for proper motor rotation and performance.

Figure 11

LEAKY SYSTEMS

Leaky water systems might keep the controller running due to the accurate pressure sensing capability of the pressure sensor. Continuous running or starts and stops do not hurt the controller, pump or motor. However, to reduce the on-time of the controller/pump/motor, a “Bump-Mode” procedure has been programmed into the drive. During very low flow (or leaky) conditions this feature periodically increases the speed of the pump several PSI above the set point and shuts off the pump. This adds some time to bleed off before the system starts up again. This “Bump-Mode” can be turned off if desired. Please call Technical Support at 1-800-345-9422 for further details.

NOTE: Artesian Drive maintains a constant pressure at the pressure sensor. Although the pressure is constant at the pressure sensor, pressure drops may be noticeable in other areas of the system when additional taps are opened. This is due to restrictions in the plumbing and will be more pronounced the farther the taps are from the pressure sensor. This would be true of any system, and if observed, should not be interpreted as a failure in the performance of the Artesian Drive.

8 (FW1086)

95 North Oak St. • Kendallville, IN 46755 • 1-800-345-9422

Although the pressure sensor can be adjusted up to 80 PSI, the maximum obtainable pressure in the system is dependent upon the full load capability of the pump at a given flow. For example, a pump is only capable of producing a pressure of 60 PSI at the flow demand. Increasing the pressure setting of the pressure sensor to 75PSI would only result in the pump running at full speed and producing a pressure of 60 PSI.

UNDERLOAD INTELLIGENT RESET

(Display showing  )

If a motor Underload fault condition occurs, the most likely cause is an overpumped well (dry well) or loss of incoming feed water to the pump. In a dry well situation to allow the well to recover, the Artesian Drive controller will wait 30 seconds to 5 minutes, determined by the amount of time the motor had been running before sensing the underload, before restarting the motor. For example, the first time the fault occurs and the pump has been running 6 minutes, the controller stops the motor and will wait 30 seconds before attempting to restart the pump. If the system would then run for 2 minutes and an underload fault recurs, the controller will wait 3 minutes before attempting to restart the pump. This schedule allows for the minimum off-time possible based on the recovery time of the well or water feed supply.

If there is an obstruction (such as a closed valve) between the pump and the pressure sensor, the controller will also sense an underload is this “dead head” condition stopping the motor to avoid damaging the pump.

OVER-TEMPERATURE

The Artesian Drive controller is designed for full power operation in ambient temperatures up to 104°F (40°C) as long as the input voltage is kept at 230 VAC. Under extreme thermal conditions, the controller will reduce the switching frequency in an attempt to avoid shutdown. If the temperature of the controller is still too hot the controller will shut itself off to

avoid causing damage to itself. Full pump output is restored when the controller temperature cools to a safe level.
