1 Important safety instructions
Read and follow the operating instructions
and safety instructions carefully before
starting operations! All modifications must be
done by qualified technicians!
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.
6
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.

(2) diaphragm tank
(3) distribution panel
(4) gate valves
(5) non return valves
(8) incoming pressure switch
(9) pressure gauges
(14) pressure transmitter

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:
Before checking the precharge pressure, take care, that the tank, is
pressureless (no water inside).

a) motor cable:
Locate the motor connections, labeled U, V, W inside the Hydrovar. Connect wires to the
terminals and rout the cable through the cable gland.
You must take a motor cable at least Ø 11.5mm if you want protection IP55. (only HV1.1)
The earth-wire of the cable has to be fixed with the screws with the earth-symbol to the
cooling body of the Hydrovar.
Connections in the conduit box
The connection of the motor cable depends on the type of the motor and can be done in
star or delta connection:
(you have to use the connection for a motor voltage of 3x230V shown on the motor label)
Star-connection
Delta-connection
b) supply cable
The main power cable is connected to the terminals labelled L1, N for the 230 VAC, single
phase input (shown in the diagram 6.2.2.1).
22
6.2.3 Control
By using the HYDROVAR drive head for constant pressure control, together with
a pressure or differential pressure transmitter, or, if required, according to
external manual control by reference of 0,5-4,5VDC, this external signal has to
be connected to the terminals X2/1, X2/2 and X2/3 of the control terminals.
6.2.4 Terminals
All externally used cables have to be shielded. Do not connect the mass of the electronic
components to other higher potentials.
All electronic ground and GND of the RS 485-interface are internally connected.
For external off/on and low water, switch contacts suitable for <10 V are necessary.
The control cable must be at least Ø 5mm.
If unshielded control cables are used, signal interference may occur and interfere with the
function of the inverter.
When connecting together the variable speed pumps (max. 4 pumps) via the interface RS
485, the terminals X3/1 and X3/2 and X3/3 are to be connected in parallel by means of a
shielded cable to every HYDROVAR drive head and programmed accordingly (*

11.2 Single Pump - Pump Protection
31
Note:
Low/no suction depends on the installation of a suction line pressure switch, or float switch
for a tank. This is connected to the Hydrovar as described earlier in the Electrical Installation
section (see chapter 6.2).
The cut off setting for this switch should be the maximum NPSH required by the pump.
To set run out protection:
Note:
Run out protection is available for one pump systems and multiple pump systems with a
common suction pipe. 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.

11.3 Single Pump – System Curve Compensation
The Hydrovar can automatically compensate
for system friction losses due to increased
flow. Tables are available in most pump
catalogues indication the amount of friction
loss that can be expected in various sizes of
pumps at different flow rates. Use these
tables to determine the friction loss 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 loss at maximum flow.

11.5 Multiple pump constant pressure and system compensation
36
When two, three or four Hydrovar speed controlled pumps are connected together in a
system via the RS485-interface, they can be programmed to work together to maintain
system pressure up to the maximum flow rate of all the pumps combined.
As the first pump reaches its maximum speed and flow, the second pump will
automatically 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 on any one pump in the
system.
Instructions:
!! Refer to chapter 11.1 (setting single pump constant pressure).
Follow these instructions for setting the required pressure and then continue with the
following steps.

ACTUAL VALUE INCREASE
0.15 bar
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 attached application
example on next page)
37
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.
For example, if the pressure drop allow 0,35 bar before the next pump starts, and
the increased pressure needed to compensate for system losses is 0,2 bar, you would
enter 0,35 + 0,20 = 0,55 bar (= calculated value of the parameter ACTUAL VALUE
INCREASE) to compensate for both system pressure drop and compensation
requirements.
Application example:
1) Pump 1 reaches the speed of ENABLE SEQ: CONTROL
2) Pressure falls and reaches the start-value of the 2
nd
pump
(= REQUIRED VALUE – ACTUAL VALUE DECREASE)
3) Pump 2 is switched on automatically
4) The required value is calculated new, after the start of the 2
nd
pump in the
following way!
New required value = REQUIRED VALUE – ACTUAL VALUE DECREASE + ACTUAL
VALUE INCREASE
Generally:
k ... Number of active pumps (k >1)
P = P
set
+ (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
Note:
This value is cumulative. An extra 0,2 bar will be added to the total system pressure with
each additional pump which turns on. For example, if the initial system pressure was 3,5
bar, pump two would create 3,7 bar, pump three would create 3,9 bar, and pump four
would create 4,1 bar system 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.

15 Possible Error messages
15.1 Low Water
XXX
Error Water
Remedy:
Check incoming pressure
If incoming pressure is normal the unit restarts itself. If there is no external low water
protection (e.g. circulating systems), you have to bridge terminals X2/6 and X2/7.
15.2 Overheating – Motor
XXX
Error-Mot-Temp
Possible causes: insufficient cooling,
ambient temperature is too high or motor
overloaded. After the cause has been remedied, the malfunction has to be reset by
cutting off the power supply for >30 seconds.
15.3 Overvoltage
XXX
Error-Overvolt
Possible cause: Check mains supply, supply
voltage too high, peak voltage owing to
switch heavy loads on the network, or RAMP 2 is to fast! Find the cause and take
countermeasures (e.g. network filter, RC-elements). Disconnect the power supply for
> 30 seconds (acknowledgement).
15.4 Undervoltage
XXX
Error-Undervolt
Possible cause: Check mains supply, faulty
fuse or phase Unsymmetry.
Disconnect the power supply for > 30 seconds (acknowledgement).
15.5 Overload
XXX
Error Overload
Possible causes: false data settings or the
pump is working at a capacity significantly in
excess of its performance data.
Ramp 1 to fast: (see chapter 13.6.3)
Max. frequency to high: (see chapter 13.5.1)
Boost to low: (see chapter 13.5.3)
Disconnect the power supply for > 30 seconds (acknowledgement).
56
15.6 Overheating of the heat sink
XXX
Error KK-Temp
The thermal sensor, mounted on the cooling
body of the HYDROVAR indicates over
temperature. Possible causes: insufficient cooling, ambient temperature is too high or
motor overloaded. After the cause has been remedied, the malfunction has to be
reset by cutting off the power supply for >30 seconds.
15.7 Sensor fault
XXX
Sensor Fault
The voltage level of the incoming analogue
input signal is supervised.
If the signal falls below the 0,5VDC-level, an Error will be displayed.
Possible causes: break of the sensor cable or the sensor itself, bad connection of the
plug of the sensor. After the cause has been remedied, the malfunction has to be reset
by cutting off the power supply for >30 seconds.
15.8 Conveyor limit fault
XXX
Error Water
The value of the programmed Conveyor limit
is not reached within the programmed delay
time Error Delay( see chapter 13.11.1 and 13.11.2).
Possible causes can be: break of the pipe before or after the pump, closed valve before
the pump, air in the pump. After the cause has been remedied, the malfunction has to
be reset by cutting off the power supply for >30 seconds.
15.9 Additional internal processor Error messages:
ERROR 1 :
EEPROM-ERROR
(corresponding data block malfunction)
ERROR 2 : Not used
ERROR 3 : Processor RAM error
ERROR 4 : Not used
ERROR 5 : Processor ROM error
ERROR 6 : Watchdog error
ERROR 7 : Clock error (quarz)
ERROR 8 : Programme error
These ERROR signals are acknowledged by disconnecting the power supply for
> 30 seconds.
If the error signal should appear again, contact customer service and provide a
detailed description of the error.

16 Maintenance
The HV1.1-1.2 control unit does not require special maintenance.
However, the cooling fan and the vent should be freed of dust occasionally.
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 Hydrovar units.
Fur further information, please ask your distributor!
