Descriptions and Features

The F&W Artesian Drive is a dependable water system

Variable Frequency Drive (VFD) that uses custom program-

ming to enhance the performance of standard centrifugal

pumps. When applied correctly to three phase motor driven

pumps, the Artesian Drive eliminates pressure cycling associat-

ed with conventional pressure switch controlled water pump-

ing 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 pres-

sure 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-the-

shelf 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 monitor-

ing (see Page 8)

- Bound pump – with auto-reversing torque

- High voltage / lightning surge

- Low line voltage

- Short circuit

Unpacking

When unpacking the unit, inspect carefully for any damage

that may have occurred during transit.

General Safety Information

Carefully read and follow all safety instructions in this

manual and on pump. Keep safety labels in good condi-

tion. Replace missing or damaged safety labels.

This is a SAFETY ALERT SYMBOL. When you see

this symbol on the pump or in the manual, look for one of

the following signal words and be alert to the potential for

personal injury or property damage.

Warns of hazards that WILL cause serious

personal injury, death or major property damage if ignored.

Warns of hazards that CAN cause serious

personal injury or death, if ignored.

Warns of hazards that MAY cause minor

personal injury, product or property damage if ignored.

IMPORTANT: Indicates factors concerned with operation,

installation, assembly or maintenance which could result in

damage to the machine or equipment if ignored.

NOTE: Indicates special instructions which are important but

are not related to hazards.

! Read these warnings and instructions carefully. Failure to follow could result in serious bodily injury and/or property damage.

Capacitors inside the Artesian Drive controller can still hold a lethal voltage even after power has been removed.

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.

the following procedure: a. Remove the rubber end-cap. b. Using a 7/32” Allen wrench (provided), turn the adjusting screw clockwise to increase pressure and counterclockwise to decrease pressure. The adjustment range is between 30 and 80 psi (1/4 turn = approximately 3 psi). c. Replace the rubber end cap. When increasing the pressure, do not exceed the mechanical stop on the pressure sensor or 80 psi. The pressure sensor may be damaged.

Reverse connection of motor cable wires at connection point U & V. Pump capacity cannot supply the demand. Use pump with higher flow rating (if head requirement is still satisfied). Temperature in the controller is too high.

Full pump output is restored when the controller temperature cools to a safe level. 5.0 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).
