Programming III. Single Pump - System Curve Compensation The AQUAVAR controller can automatically compensate for system friction losses due to increased flow. Tables are available in most pump catalogs indicating the amount of friction loss that can be expected in various sizes of pipe at different flow rates. Use these tables to determine the friction loss for the pipe size you are using at your maximum flow rate. H f = 100% %f WINDOW Diagram 15 shows a typical system curve.

Programming Circulator applications On circulator pumps, the system curve can be automatically tracked through the use of a differential pressure transducer. This pressure transducer reads the outgoing discharge pressure and the incoming return pressure and compensates for differences in pressure as demand and speed increase. Programming is the same as just covered for the single transducer version. Data on the differential pressure transducer can be found in Appendix A. IV.

Screen Save ??? Saved t 9.
Programming V. Single Pump - Level Control Applications For drainage applications using a surface pump, the transducer is typically needed to measure pressure on the suction line. As the catch basin or tank empties, the pressure will decrease, and the pump needs to slow down and eventually stop. This is the opposite way the AQUAVAR controller would usually respond. To change to suction side measurement: 1.
Programming VI. Single Pump - Submersible Applications and Minimum Frequency It is possible to use the wall mounted version of the AQUAVAR controller with a submersible pump. *Never attempt to mount an AQUAVAR controller on the pump itself in these applications since the AQUAVAR controller is not designed to be submerged. The standard distance allowed between the pump and the AQUAVAR controller is up to 60 feet. If you need a longer connection, be sure to contact your distributor for a drive applied filter.

Config.
Programming VII. Setting A Second Fixed Required Value The AQUAVAR controller can also be used in applications where the required value changes. As an example, a single pump system might be used to supply both water supply and irrigation needs on a farm. When the irrigation system is used, the pressure which needs to be maintained is higher than the pressure for normal water supply.

ADC-1, Ext ADC-U 0-10V, Ext ADC-V 2-10V) involve variable second values controlled by a second sensor. These are discussed in the next section.
Programming VIII. Variable Second Required Value In this section, we will cover the set up and programming of the AQUAVAR for a second sensor input. This sensor can be either a 4-20mA or 0/2-10V device such as a pressure transducer, flow transducer, heat sensor, etc. When connected to the AQUAVAR, the output of this second sensor becomes the new set point. As input from the second sensor changes, the set point will also change.

Offsets It is also possible to use second sensor input as an offset for the primary required value. An example would be locating the second sensor in a supply tank or well and setting an offset so that when the water level got too low, the pump discharge pressure setting would be reduced until the tank or well had recovered.
Programming analogue value 1 Level 1 % Level 2 % required value 75 PSI Intensity 1 - 10% 60 PSI Intensity 2 - 20% 45 PSI additional input 2 0%=4mA (0V/2V) 20% 80% 100%=20mA (10V) At Level 1 and Level 2, you enter the required value in percent from the Second Additional input (20%) and (80%). Intensity one and two depend on the Sensor range of the external value signal. The Intensity 1 that you have entered is valid until you reach Level 1, after reaching Level 1 the Required Value has no offset.
Programming Press * Intensity 1 +xx.x% key to advance to: Use the andtarrow keys to enter the % of the Intensity 1 -10.0% required value you want to increase or decrease when the second sensor input is below Level 1. The chart on the previous page uses -10% as an example. This represents an application where the second sensor is in a well or tank.
Programming Electrical Connection Dry contacts are available to connect a relay at X2/4-X2/5 (normally closed) or X2/6-X2/5 (normally open). The relay is located between main line power and the second, full speed, pump. NOTE: 250 VAC, 1 amp is maximum for the above contacts. In this method, the second (slave) full speed pump may be either single or three phase with any motor enclosure. The main pump (AQUAVAR controlled) must still be a three phase motor and TEFC if the AQUAVAR is to be pump mounted.

Saved andtarrows until: Using the above settings, when there is system demand, the AQUAVAR pump will start first and maintain pressure until it reaches 58 Hz. At that point, the relay will start the slave pump at full speed.
Programming X. Multiple Pump Constant Pressure and System Curve Compensation When two, three, or four AQUAVAR controller controlled pumps are connected in a system, they can be programmed to work together to maintain system pressure up to the maximum flow rate of all pumps combined. As the first pump reaches its maximum speed and flow, the second pump will automatically turn on (and so on).
Programming Multiple Pump Constant Pressure... continued Generally, a slight pressure drop is allowed on the first pump before the next is started. This allows for brief system fluctuations without pump cycling. Once the next pump starts, however, you will want the system to resume its normal set pressure. 7 H ∆P 6 ∆P 5 4 P1 P1 + P2 P1 + P2 + P3 3 5.

Programming XI. Multiple Pump - Pump Protection The AQUAVAR controller can protect the pump by shutting it off in low/no suction or run out conditions. Note Low/no suction protection depends on the installation of a suction line pressure switch or float switch for a tank. This switch is connected to the AQUAVAR controller as described earlier in the electrical installation section. The cut out setting for a suction pressure switch should be greater than the maximum NPSH required by the pump.

Operator Custom Features and Displays Refer to the overall Program Flow Chart for the location of the following operator custom features. To access a particular feature: • Enter the password (66) at the Main Menu. * • Scroll to the selected feature by using the “ ” key. Other features have already been discussed in the application set-up instructions described earlier. Note Custom features are pre-programmed to default settings.
Operator Custom Features and Displays Ramp 1 This ramp is the fast run up time used when the pump first comes on and is trying to reach the set point. The normal set point for this ramp is 4 seconds for the horse power range 2 through 15 hp. For versions with higher horsepowers, 20 hp and above, the setting should be 10 seconds minimum. A setting which is too fast may overload the inverter. A setting which is too slow tends to cause uneven outgoing pressure (pressure drops).
Operator Custom Features and Displays Minimum Frequency Settings between 0 and 50 Hz are possible. When a minimum frequency is set, the AQUAVAR will not run the pump below this speed. See the section on submersible pumps. Config. F Min This setting allows you to configure a minimum frequency in one of two ways. If you select “f>0”, the inverter will go down to the minimum frequency and then continue running at that level for the delay time (see next features).
Operator Custom Features and Displays Controller - Used for a single AQUAVAR controlled pump Multicontroller - Used where several AQUAVAR pumps are connected via RS485 Synchronous Controller - Used for multipump systems where all pumps will run at the same frequency. Actuator - Used if you have an external (PID) controller. In this mode the internal controller is turned off. The output frequency changes proportionally based on sensor input (X1/2) and the following chart.
Operator Custom Features and Displays Regulation Mode The “Normal” setting increases the output speed with falling signal (constant pressure in discharge). The “Inverse” setting decreases the output speed with falling signals (suction control). Submenu Sequence Control - for further information see Section V Use this menu to allow starting and stopping of up to 4 pumps with the RS-485 communication port. The following setup items allow the user to determine when the pumps will start and stop.
Operator Custom Features and Displays Synchronous Limit To deactivate synchronous control, set this value below 0 HZ. This will be the lowest speed that multiple pumps will operate prior to switching off the last pump in sequence. For 60 Hz systems using synchronous mode, this would normally be set to 40 Hz. This window is also used for the stop value of a slave pump. Synchronous Window This is a frequency offset that increases the synchronous limit that each lag pump is stopped at.
Operator Custom Features and Displays ADC Reference This setting tells the unit where to look for the actual value signal. Set to “LOCAL” if the actual value is obtained from a 4-20mA transmitter wired to the unit’s actual value input terminals (X1: 2, 3). Set to “REMOTE” if the actual value is obtained from the RS-485 port via a remote device. Default is local. Frequency Lifting Allows modification of the required pressure to accommodate for system frictional losses due to increased flow.
Operator Custom Features and Displays Test Run The AQUAVAR controller can carry out a test run of the pump either automatically or manually. For automatic settings, enter the number of hours you want to elapse between the last pump shut down and the test. Possible settings are between 10 and 100 hours. When the time has elapsed, the pump will automatically turn on at 50% of maximum frequency (normally 30 hz) for 20 seconds and then turn off again.
Operator Custom Features and Displays Operating Hours This counter displays the total amount of time that the AQUAVAR controller drive head has operated, (whether the pump was running or not). This time can be reset to zero by pressing the up and down arrows at the same time for 25 seconds. Total Run Time This display shows the total run time of the pump motor in hours and minutes. This display resets automatically when Operating Hours is reset.
Repair of Faults and Errors Repair of Faults and Errors WARNING Disconnect power from the AQUAVAR controller before connecthazardous voltage ing the faults to avoid potential for automatic pump restart. WARNING Lack of Water This error message will be displayed when a switch has indicated that the incoming water pressure or water level in a suction tank falls below the required NPSH of the pump.
Repair of Faults and Errors Overloaded The most common problem is incorrect program settings causing the pump to exceed its duty range. When this happens, the AQUAVAR controller will shut down the system to protect the pump and motor. Check programming, maximum system requirements, pump blockage due to solids, broken mechanical seal, defective non-return valve, pump motor run in reverse, motor amps, and pump selection.

Appendix C Interference Suppression Measures Introduction Electrical/electronic devices are capable of influencing or disturbing each other through connecting cables or other metallic connections. Interference suppression measures (electromagnetic compatibility) consists of two elements: interference resistance and interference emission.
Appendix C • Take care not to damage the shield cross section when connecting it to the continuing lines. This raises the RF resistance of the shield and radiates rather than discharges the RF energy traveling on the shield. Shields, particularly those on control cables, must not be routed through pin contacts (plug connectors). • When shielded cables must pass through a plug connection, use the metallic hand guard of the plug for the continuation of the shield.
Appendix D The final difference is the addition of a DIP switch SW4 which can be used to select a lower switching frequency. This could be used to improve the motor efficiency of submersible pumps, and overall power consumption. This will also increase the audible motor noise. Before changing this switch the AQUAVAR controller must be disconnected from the power supply.
