1 Important safety instructions
Read and follow the operating instructions
and safety instructions carefully before
starting operations! All modifications must be
In addition to the instructions contained in these operating instructions please pay
attention to universal safety and accident prevention regulations.
The HYDROVAR 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.
Unauthorised 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 must 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 HYDROVAR drive
head (the capacitors in the intermediate circuit have to be discharged by the
installed discharge resistors first).
Voltages of up to 400 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 authorised 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 insulated.
done by qualified technicians!

The HYDROVAR 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 energised 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 potential-free 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.
The operating instructions must be read, understood and followed by the operating
personnel. We point out that we accept no liability for damage and operating disorders
which are the result of non-compliance with the operating instructions.
Please
note:
High voltage tests of the inverter or the motor may damage the
electronic components! Hence bridge before the in- and outgoing
terminals L -N -- U- V-W.
To avoid incorrect metering by capacitors incorporated in the
electronic part isolate the motor from the Hydrovar Drive head.

2 System Design
The following diagrams show typical single pump and multi-pump systems using the
Hydrovar 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.
Single pump layout
Multiple pump Layout
(1) pump with drive head
(2) diaphragm tank
(3) distribution panel
(4) gate valves
(5) non return valves
(8) incoming pressure switch
(9) pressure gauges
(14) pressure transmitter
7
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 Hydrovar control unit, it is not necessary to have a large tank
for supply purposes. In selecting a tank, make sure it can withstand systems pressure. The
tank should have a capacity of more than 10% of the maximum system flow rate l/min of
one pump.
Ask of required certificates needed for your country!
Precharge the tank to the following:
Solldruck / required pressure [bar]
Before checking the precharge pressure, take care, that the tank, is
pressureless (no water inside).
