1 Important safety instructions
In addition to the instructions contained in these operating instructions please payattention to universal safety and accident prevention regulations.
The TECHNOVAR drive head must be disconnected from the power supply before any workcan be carried out in the electrical or mechanical part of the system.Installation, maintenance and repair work may only be carried out by trained, skilled andqualified personnel.Unauthorized modifications or changes to the system make all guarantees null and void.When in operation, the motor can be stopped by remote control, whereby the drive head andthe motor remain under voltage. For safety reasons, the unit has to be disconnected from thepower supply when carrying out work on the machinery as locking out the equipment byswitching off the release mechanism or set value cannot prevent accidental starting of themotor.
When the drive head is connected to power supply, the components of thepower unit as well as certain components of the master control unit are alsoconnected to the power supply.
Touching these components seriously endangers life !
Before removing the frequency inverter cover the system must bedisconnected from the power supply. After switching off the power supplywait at least 5 minutes before starting work on or in the TECHNOVAR drivehead (the capacitors in the intermediate circuit have to be discharged by theinstalled discharge resistors first).
Voltages of up to 800 volts are possible (if there are faults it can be higher)
All work, carried out when the frequency inverter is open, may only beperformed by qualified authorized staff.
Furthermore, care must be taken not to short circuit the neighbouringcomponents when connecting the external control wires and that opencable ends which are not in use are isolated.
Operating Instruction
6
The TECHNOVAR drive head contains electronic safety devices whichswitch off the control element in the event of faults, whereby themotor has zero current but remains energized and comes to a halt. Themotor can also be halted by mechanical blocking. If it is switched offelectronically the motor is disconnected from the mains voltagethrough the electronics of the frequency converter but is not potential-free in the circuit.In addition voltage fluctuations, especially power failures can cause thesystem to switch off itself.
The system may only be put into operation when it has been earthened. In addition,equipotential bonding of all pipes must be ensured.
Warns that failure to observe the precautions may cause electrical shock.Failure to follow these instructions could result in serious personal injury or death.
Warns that failure to follow these instructions could result in serious personalinjury or death as well as property damage.
Repair of faults can cause the motor to start up again!

2 System Design
The following diagrams show typical single pump and multi-pump systems using theTechnovar control unit. Connection can be made directly to a water supply or water can bedrawn from a break tank or well. In the case of break tanks and wells, level switches, shouldbe used to shut down the pumps when water is low. In the direct connection, a pressureswitch on the suction side should be used.

3 Pressure tank
A diaphragm pressure tank is used on the discharge side of the pump or pumps to maintainpressure in the line when there is no demand. This will keep the pumps from continuing torun. With the Technovar control unit, it is not necessary to have a large tank for supplypurposes.In selecting a tank, make sure it is permit and suitable for systems pressure. The tank shouldhave a capacity of more than 10% of the maximum system flow rate g/min of one pump (alsoin a multiple pump system!).
Pre charge the tank to the following:
Required pressure
Note: De-pressurize the tank prior to charging to ensure accuracy of thepre-charged pressure.

8.3 Single Pump – Pump Protection
The Technovar has the ability to protect the pump by shutting off in low/no suction or run outconditions.
Note: Low/no suction protection depends on the installation of a suction linepressure switch, or float switch for a tank. This switch is connected tothe Technovar. The cut out setting for a suction pressure switch shouldbe greater than the minimum incoming pressure, required by the pump.
Note: Run out protection is available for one pump systems and multiple pumpsystems with a common suction pipe. (described at chapter ”ConveyorLimit” 11.30.1 In multiple pump systems with separate suction pipes,you can not avoid dry running by measuring the system pressure,because the pressure is produced from another pump in the system.
8.3.1 To set run out protection
Hold the button for 3 seconds and the display changes to PASSWORD0000
Password:The password protection prevents untrained personal from accidentally changing of the basesettings:
Set ‘Password 0066’ by pressing or PASSWORD0066

8.4 Single Pump – System Curve Compensation
The Technovar can automatically compensate for system friction losses due to increased flow.Tables are available in most pump catalogs, indicating the amount of friction losses that canbe expected in various sizes of pipes at different flow rates. Use these tables to determine thefriction losses for the pipe size you are using at maximum flow rate.This Diagram shows a typical system curve. The system pressure set point is shown at shutoffand pressure increase is shown for increasing flow.Calculate the pressure required to overcome friction losses at maximum flow.

8.5 Multiple Pump - Constant Pressure and System Curve Compensation
When two, three or four Technovar controlled pumps are connected in a system, they can beprogrammed to work together to maintain system pressure up to the maximum flow rate ofall pumps combined. As the first pump reaches its maximum speed and flow, the second willautomatically turn on (and so on). In addition, the sequence of the pump that will run first(lead pump) can be automatically varied to reduce premature wear of any pump in thesystem.
Hold the button for 3 seconds and the display changes to PASSWORD0000

If more than one pump are working together, connected via the RS485 interface(follow-up pump control), the Multicontroller must be set with the buttons or .Synch. Controller:The Synchronous Controller mode is working in the same way like the Multicontroller. Theonly difference is, that all pumps in the multi pump system are running at the samefrequency.Actuator:The Actuator application is only used if you have an external controller and the Technovar isused as a standard frequency converter. In the Actuator-Mode, the internal controller is shutoff, and the output frequency is proportional to the input signal (X1/2) � 4-20 mA = 0 -fmax. The frequency changes with the programmed ramps 1 and 2. The functions of lowwater, thermal protection and external ON/OFF are still working.

ACTUAL PRESSURE INCREASE (=LIFT VALUE):This value, together with the fall value (ACTUAL VALUE DECREASE) determines theincrease of the required value after starting of the following pumps (see example)
Operating Instruction
40
Generally a slight pressure drop is allowed on the first pump before the next is started.This allows for brief systems fluctuations without pump cycling. Once the next pumpstarts, however, you will want the system to resume its normal set pressure.
To do this, enter the amount of pressure drop you willallow before the next pump starts (= value ofparameter ACTUAL VALUE DECREASE). The diagramshows the pressure drop and increase.
To increase the pressure even more to compensate forsystem loss at higher flows, enter the total of thesystem drop allowed before next pump starts and theincreased pressure (ACTUAL VALUE INCREASE) desired.
Application example:1) Pump 1 reaches the speed of ENABLE SEQ: CONTROL or more2) Pressure falls and reaches the start-value of the 2nd pump
(= REQUIRED VALUE – ACTUAL VALUE DECREASE)3) Pump 2 is switched on automatically4) The required value is calculated new, after the start of the 2nd pump in the following
way!
New required value = REQUIRED VALUE – ACTUAL VALUE DECREASE + ACTUAL VALUE INCREASE
Generally:k ... Number of active pumpsP = Pset + (k-1)*[lift value – fall value]
� Lift value = Fall value � Pressure constant when pumps switch on� Lift value > Fall value � Pressure rises when lag-pump switches on� Lift value < Fall value � Pressure falls when lag-pump switches on
Enter the required value by pressing the and button ACTU. VALUE INC.7,1 psi
