System Design - Typical Constant Pressure Systems

The following diagrams show typical single pump and multi-pump systems using the AQUAVAR con-troller. Connection can be made directly to a water supply or water can be drawn from a supply tank or well. In the case of supply tanks and wells, level switches, (item 10) can be used to shut down the pumps when water is low. In the direct connection, a pressure switch on the suction side (item 8) can be used.

A diaphragm pressure tank is used on the discharge side of the pump or pumps to maintain pres-sure in the line when there is no demand. This will keep the pumps from continuing to run. With the AQUAVAR controller, it is not necessary to have a large tank for supply purposes. In selecting a tank, make sure it can withstand maximum system pressure. The tank should have a capacity of at least 10% of the maximum system flow rate in gpm. Pre-charge the tank to the following:

CONTROLLER CAN CAUSE SHOCK, BURNS, OR DEATH.

WARNING!

TOUCHING THESE COMPONENTS SERIOUSLY ENDANGERS LIFE! Voltages of up to 800 volts are possible (higher if there is a fault).

Before removing the AQUAVAR controller drive top cover, the system must be discon-nected from the main power supply. After switching off the power supply, you must wait at least 5 minutes before starting work on or inside the AQUAVAR controller drive head. This allows the capacitors in the circuit to be discharged by the discharge resistors.

Note

Care must be taken when connecting external control wires and jumpers to avoid short circuit to neighboring components.

Note

Repair of electrical faults can lead to the automatic restart of the motor and pump.

You must remove all main line power to the AQUAVAR controller before attempting to correct a fault.

Installation Procedures

Step 2 - Mounting the AQUAVAR II controller:

AQUAVAR Controller The AQUAVAR controller may be installed as a wall or panel mounted unit. The AQUAVAR controller may be mounted up to 60 feet away from the pump motor*. In addition, alternative motor enclosures may be selected such as ODP, explosion proof or wash down motors in addition to the TEFC enclo-sure required for on the pump mounting.

Typical applications for the AQUAVAR Wall Mount controller include:

1. Hazardous environment applications including high heat, humidity or combustibility.

2. Installation to an existing pumping system with non-standard motors.

3. Installations where the operator desires all controls to be grouped together.

Mounting of the AQUAVAR II Controller

1. An alternative mounting style is used in the AQUAVAR II controller configuration.

In this style, the AQUAVAR II controller is supplied with a fan and mounting bracket already installed and can be mounted to a wall or panel.

2. The mounting bolts for all units should be 1⁄4". The length of bolt and the strength of the mounting surface must be adequate to support the weight of the AQUAVAR II controller.

3. The AQUAVAR II controller may be positioned up to 60 feet from the pump motor. The pump motor must be three phase. Unlike the standard AQUAVAR controller, the motor may be ODP, TEFC or explosion proof.*

4. Mount the AQUAVAR controller to the panel, wall or frame using bolts at the points indicated on the following drawings. Be sure the unit is level and secured to the mounting surface before continuing.

5. Ensure plenty of airflow for the AQUAVAR controller, when mounting.

*NOTE: If the AQUAVAR II controller is more than 60 feet wire length to motor, then the use of a load reactor (impedance coil) is required.

TION CAN RESULT IN INJURY OR EQUIPMENT DAMAGE.

Step 5 - Considerations for Mounting AQUAVAR Controllers in Host Enclosures

The AQUAVAR controller is available from stock in a variety of enclosures that meet the requirements of almost any application. Yet, special applications (such as use in washdown environments or in integrated systems) may make it desirable to mount AQUAVAR controllers in a host enclosure.

When the AQUAVAR controllers are mounted in a host enclosure, the watts dissipated by the drives must be dissipated by the host enclosure. If this is not accomplished, the control circuitry of the AQUAVAR controller will be damaged.

Two techniques are available for mounting AQUAVAR controllers in a host enclosure:

• The controllers may be entirely enclosed in the host enclosure or

• The controllers may be mounted with their cooling fins outside of the host enclosure.

The following sections discuss these two mounting techniques in greater detail.

Models Entirely Enclosed in the Host Enclosure When an AQUAVAR controller is entirely enclosed in a host enclosure, the host enclosure must be properly sized to dissipate the heat generated by the controller and any other power-dissipated by the various models of the AQUAVAR controller at various switching frequencies. Use this information to adequately size the host enclosure.

Models with Fins External to the Host Enclosure By mounting an AQUAVAR controller so that its heatsink fins are outside of the host enclosure, you may select a smaller host enclosure than that required when the controller is mounted entirely inside the host enclosure. For most applications with this type of mounting, typically you will not need such additional cooling devices as fans, heat exchangers or air conditioners.

The amount by which the load on the host enclosure is reduced is the amount of watts dissipated by the heatsinks of the controllers. Table 3 shows the watts dissipated by each AQUAVAR model after deducting the amount of watts dissipated by the heatsinks of the model. Use the values shown in the table to adequately size the host enclosure.

Step 6 - Maintenance Minimum Torque Values to Secure Cover

If you remove the cover of an IP55 AQUAVAR controller, it is imperative that the cover be closed and re-secured with sufficient tightness to maintain environmental integrity. The table below specifies the torque values for the bolts that secure the covers on the various models.

Step 7 - General Wiring Information Wiring Practices

When making power and control connections, observe these precautions:

• Follow all Federal, State, NEC codes and local codes.

• Never connect input AC power to the motor output terminals T1/U, T2/V or T3/W – or damage to the controller will result.

• Power wiring to the motor must have the maximum possible separation from all other power wiring. Do not run in the same conduit, this separation reduces the possibility of coupling electrical noise between circuits.

• Cross conduits at right angles whenever power and control wiring cross.

• Good wiring practice also requires separation of control circuit wiring from all power wiring.

Since power delivered from the controller contains high frequencies which may cause interference with other equipment, do not run control wires in the same conduit or raceway with power or motor wiring.

Considerations for Power Wiring Power wiring refers to the line and load connections made to terminals L1/R, L2/S, L3/T and T1/U, T2/V, T3/W respectively. Select power wiring as follows:

• Use only UL recognized wire. (Shielded or armored wire is recommended for power and motor wiring.)

• Wire voltage rating must be a minimum of 300 V for 230 Vac systems and 600 V (Class 1 wire) for 460 Vac and 575 Vac systems.

AV2 Enclosure Type Torque Value

English Metric 1-20 HP, 230 Vac input 12 in-lbs 1.35 Nm

IP55 1-20 HP, 460 and 575 Vac input 18 in-lbs 2.03 Nm 25-75 HP, 460 and 575 Vac input 12 in-lbs 1.35 Nm

• Use circuit breakers on the incoming power lines.

• Grounding must be in accordance with NEC and CEC. If multiple AQUAVAR controllers are installed near each other, each must be connected to ground. Take care to not form a ground loop. Maintain a common ground.

• Wire must be made of copper and rated 60 / 75ºC (unless otherwise specified in the table below). Refer to Tables 4, 5 and 6 for recommended wire gauges and temperature ratings.

Considerations for Control Wiring Control wiring refers to the wires connected to the control terminal strip. Select control wiring as follows:

• Shielded wire is recommended to prevent electrical noise interference from causing improper operation or nuisance tripping.

• Use only UL™ recognized wire.

• Wire voltage rating must be at least 300 V for 230 Vac systems.

Table 6: Recommended Wire Gauges (575 Vac Models)

Step 8 - Input Line Requirements Line Voltage

See the Power and Current Ratings table for the allowable fluctuation of AC line voltage for your particular model. A supply voltage above or below the limits given in the table will cause the drive to trip with either an overvoltage or undervoltage fault.

When supplying line voltages other than the factory default values (either 230 Vac, 460 Vac or 575 Vac depending on the model), set the Supply Voltage parameter to the appropriate value.

Exercise caution when applying the AQUAVAR controller on low-line conditions.

For example, and AQUAVAR controller will operate properly on a 208 Vac line – but the maximum output voltage will be limited to 208 Vac. Now if a motor rated for 230 Vac line voltage is controlled by this drive, higher motor currents and increased heating will result.

Therefore, ensure that the voltage rating of the motor matches the applied line voltage. If other than 60 Hz output is desired, proper V/Hz can be programmed into the AVII by setting the Nom Mtr Voltage and Nom Mtr Freq parameters.

Use of Isolation Transformers and Line Reactors The AQUAVAR controller is is perfectly suitable in most cases for direct connection to a power source as specified in this manual and the technical nameplate affixed to the unit. There are however a few cases where a properly sized isolation transformer or line reactor should be employed to minimize the risk of drive malfunctionor damage or nuisance tripping:

• As noted in Table 7, transformer sizing, when line capacity is greater than 10 times the KVA rating of the drive. Consult the factory for assistance in sizing the reactor.

• When power factor correction capacitors are employed on the drive’s power source.

• When the power source is known to be subject to transient power interruptions or significant voltage spikes.

• When the power source supplying the drive also supplies large devices such as DC drives that contain controller rectifiers.

Transformer kVA 2 4 5 9 13 18 23 28 36 42 56 70 90 112

Phase Imbalance Phase voltage imbalance of the input AC source can cause unbalanced currents and excessive heat in the drive’s input rectifier diodes and DC bus capacitors. Phase imbalance can also damage motors running directly across the line.

3. Place the square gasket over the end of the transducer, plug the cable connector on, and tighten the screw.

• The transducer is supplied with 1⁄4” NPT threads for direct mounting in the discharge piping.

4. Now select one of the remaining ports in the AQUAVAR controller to route the transducer cable.

Route the transducer cable through the strain relief, cut to length and connect to locations X1 #2 and #3 as shown in Diagram 7. (Note: Control board is mounted to the inside front cover of the drive enclosure.) The brown wire is connected to X1 #3 and the white wire to X1 #2.

Tighten strain relief.

5. Terminals Found on the AV II Drive Control Board (Internal Drive) Description of the Control Terminals: Figure 8 shows the control terminals found on the I/O board of the AV II drive. (The actual control board cannot be accessed by the user.) These terminals are prewired by the factory with color coded wires below.

Note that due to labeling constraints, the labels for some terminals start on the left (either on the side or top of the terminal block), are interrupted by the terminal screw, and then finish on the right (either on the side or top of the terminal block). For example, terminal A11 is labeled with A on the left side of the block and 11 to the right of the terminal screw on top of the block. Similarly, terminal NC2 is labeled with N to the left of the terminal screw on top of the block and then C2 on the right side of the block.

As is shown in the figure, the terminals are divided into four terminal blocks, each of which pulls apart for ease of field wiring:

• TB1 - analog input, analog output and digital output terminals.

• TB2 - output relay 1 (R1).

• TB3 - output relay 2 (R2).

• TB4 - digital input terminals.

Table 12 starting on the next page describes the control terminals.

Cable connector will fit on one way only! Do not force on or damage may occur.

Electrical Connections continued Table 12: Description of AV II Drive Control Terminals (Internal Drive)

Terminal Description TB2 Terminal Block

Common terminal for the first auxiliary relay. The function of the relay is RC1 set by parameter R1 Configure. The default setting is for the relay to activate when a fault is detected (Drv Flted).

NC1 Normally-closed contact for the first auxiliary relay. It will open when the relay is activated.

NO1 Normally-open contact for the first auxiliary relay. It will close when the relay is activated.

TB3 Terminal Block (Drive Run Contacts) Common terminal for the second auxiliary relay. The function of the relay

RC2 is set by parameter ROUT R2 Config. The default setting is for the relay to activate when the drive is running.

The contact ratings are 115 VAC at 1 A or 230 VAC at 0.5 A.

NC2 Normally-closed contact for the second auxiliary relay. It will open when the relay is activated.

NO2 Normally-open contact for the second auxiliary relay. It will close when the relay is activated.

TB4 Terminal Block Enable terminal. A jumper is placed between this terminal and the +2 terminal at the factory. You may replace this with a contact if desired. The

EN circuit from EN to +24 must be closed for the drive to operate.

Note that unlike all other terminals, this terminal cannot be configured for “pull-down logic.” That is, a high input to this terminal is always regarded as true – and must be present if the drive is to operate.

Digital inputs. The function of a digital input is configured by the

D3 to D10 parameter with the same name as the digital input in the DI Configure parameter group.

Digital input. In 3-wire control, this must be a Stop input. In 2-wire

D2 control, it may be configured to another function with parameter D2 Configure.

D1 Digital input. This must be a Start or Run input.

6. For multi-pump systems: Use a three core shielded cable to connect terminals 1, 2, and 3 on X5 between the AQUAVAR controller units. These are the RS-485 interface connections.

(See Diagram 11 and 13). Note: either RS485 port can be used.

• Connect pump one to pump two, two to three, and three to four (maximum is 4 pumps).

7. External pressure switch or float switch- (if used) to check incoming pressure and low/no suction. Connect to terminal block X1 at the 6 and 7 location. Refer to Diagram 11.

When using a suction pressure switch, set the cut off at the maximum NPSH required by the pump.

8. External on/off If used to turn the AQUAVAR controller on or off from an external panel or controller, connect to terminal block X1 at the 4 and 5 location (refer to Diagram 7, page 24).

9. Analog output of pressure A meter can be connected to X9 pins 2 and 1 for remote display of actual system pressure.

The meter must be 0-10 VDC volt with no more than 2 mA.

10. Second Sensor Input The ground pin (X1-10) used for analog output can also be used to bridge a connection for a second sensor. This can be digital (on/off) such as a switch which would be connected between X1-10 and X1-14. Another choice is a sensor with a voltage signal of 0-10V or 2-10V which would be connected to X1-10 and X1-13. A final choice is a 4-20 mA current sensor which would be connected to pins X1-10 and X1-12.

Installation Procedures

Power supplies using G.F.I. breakers will cause nuisance tripping which will result in the AQUAVAR controller displaying an “undervoltage” fault.

Note

If an external switch is NOT used, install a jumper wire between X1 Locations 4 and 5.
