Operating Instruction

1 Important safety instructions

In addition to the instructions contained in these operating instructions please pay attention to universal safety and accident prevention regulations.

The TECHNOVAR drive head must be disconnected from the power supply before any work can 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 and qualified 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 and the motor remain under voltage. For safety reasons, the unit has to be disconnected from the power supply when carrying out work on the machinery as locking out the equipment by switching off the release mechanism or set value cannot prevent accidental starting of the motor.

When the drive head is connected to power supply, the components of the power unit as well as certain components of the master control unit are also connected to the power supply.

Touching these components seriously endangers life !

Before removing the frequency inverter cover the system must be disconnected from the power supply. After switching off the power supply wait at least 5 minutes before starting work on or in the TECHNOVAR drive head (the capacitors in the intermediate circuit have to be discharged by the installed 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 be performed by qualified authorized staff.

Furthermore, care must be taken not to short circuit the neighbouring components when connecting the external control wires and that open cable ends which are not in use are isolated.

Operating Instruction

The TECHNOVAR drive head contains electronic safety devices which switch off the control element in the event of faults, whereby the motor has zero current but remains energized and comes to a halt. The motor can also be halted by mechanical blocking. If it is switched off electronically the motor is disconnected from the mains voltage through the electronics of the frequency converter but is not potentialfree in the circuit. In addition voltage fluctuations, especially power failures can cause the system to switch off itself.

Repair of faults can cause the motor to start up again!

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 personal

injury or death as well as property damage.

Operating Instruction

2 System Design

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

Operating Instruction

3 Pressure tank

A diaphragm pressure tank is used on the discharge side of the pump or pumps to maintain pressure in the line when there is no demand. This will keep the pumps from continuing to run. With the Technovar control unit, it is not necessary to have a large tank for supply purposes. In selecting a tank, make sure it is permit and suitable for systems pressure. The tank should have a capacity of more than 10% of the maximum system flow rate g/min of one pump (also in a multiple pump system!).

Pre charge the tank to the following:

Required pressure

Pre charge pressure (psi)

Note:

De-pressurize the tank prior to charging to ensure accuracy of the pre-charged pressure.

8.3 Single Pump – Pump Protection

Password:

The password protection prevents untrained personal from accidentally changing of the base settings:

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 Technovar. The cut out setting for a suction pressure switch should be greater than the minimum incoming pressure, required by the pump.

Run out protection is available for one pump systems and multiple pump systems with a common suction pipe. (described at chapter ”Conveyor Limit” 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.

8.4 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 can be expected in various sizes of pipes at different flow rates. Use these tables to determine the friction 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 shutoff and pressure increase is shown for increasing flow. Calculate the pressure required to overcome friction losses at maximum flow.

ACTUAL PRESSURE INCREASE (=LIFT VALUE):

This value, together with the fall value (ACTUAL VALUE DECREASE) determines the increase of the required value after starting of the following pumps (see example)

Operating Instruction

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 pump starts, however, you will want the system to resume its normal set pressure.

To do this, enter the amount of pressure drop you will allow before the next pump starts (= value of parameter ACTUAL VALUE DECREASE). The diagram shows the pressure drop and increase.

To increase the pressure even more to compensate for system loss at higher flows, enter the total of the system drop allowed before next pump starts and the increased pressure (ACTUAL VALUE INCREASE) desired.

Application example:

1) Pump 1 reaches the speed of ENABLE SEQ: CONTROL or more

2) Pressure falls and reaches the start-value of the 2nd pump

(= REQUIRED VALUE – ACTUAL VALUE DECREASE)

3) Pump 2 is switched on automatically

14 Maintenance

The TECHNOVAR control unit does not require special maintenance. However, the cooling fan and the vents should be free of dust occasionally.

14.1 Notes

When replacing the control card in a plant with more than one pump ensure, that the same control card version (V/STK/X) is used in all Technovar units.

For further information, please ask your distributor!
