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!
Warns that failure to observe the precaution may cause electric shock
Warns that failure to observe the precaution may cause personal injury or
damage to property.
In addition to the instructions contained in these operating instructions please pay
attention to universal safety and accident prevention regulations.
Basically the HYDROVAR 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.
During operation, the motor can be stopped by open a digital input or manually operated,
whereby the HYDROVAR and the motor remain under voltage. For safety reasons, the
HYDROVAR has to be disconnected from the power supply when carrying out work on the
machinery.
When the HYDROVAR is connected to power supply, the components of the
power unit as well as certain components of the control unit are connected to
the power supply.
Touching these components seriously endangers life!
Before removing the HYDROVAR cover the system must be disconnected from
the power supply. After switching off the power supply wait
at least 8 minutes before starting work on or in the HYDROVAR (the
capacitors in the intermediate circuit are discharged by the installed discharge
resistors).
Voltages of up to 800 volts are possible (in case of an error these also can be
higher)
5
All work, carried out at opened HYDROVAR, may only be performed by
qualified and authorized staff.
Furthermore, care must be taken not to short circuit the neighbouring
components when connecting the external control wires and all cable ends
which are not in use are isolated.
The HYDROVAR 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
HYDROVAR 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 grounded.
In addition, equipotential bonding of all conductive pipes must be
ensured.
(Please consider local installation standards!)
High voltage tests of the HYDROVAR or the motor may damage the
electronic components! Hence bridge the in- and outgoing
terminals L1 - L2 - L3 -- U-V-W before.
To avoid incorrect metering by capacitors incorporated in the electronic
part isolate the motor from the HYDROVAR.
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.

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. In such a case,
a pressure switch on the suction side should be used.

(7) pressure gauge
(8) pressure transmitter
(9) drain tap
2.1 Pressure tank
A diaphragm pressure tank is used on the discharge side of the pump to maintain pressure
in the line when there is no demand. This will keep the pumps from continuing to run at
zero demand. With the HYDROVAR, no large tanks are required for supply purposes.
The tank must be permitted and suitable for systems pressure. The tank should have a
capacity of min. 10% of the maximum system flow rate [l/min] of one pump (also valid for
multi-pump system).
Example:
Maximum flow rate of the pump = 250 litres per minute
Minimum volume of the tank = 250 x 0.10 = 25 litres
The pre-charge pressure of the tank can be determined by using the following table:
required pressure (bar) (system pressure)
precharge pressure (bar) (air pressure)
NOTICE:
To check and set the right pre-charge pressure, please make the tank
pressure less before.

3 Product Overview
3.1 Hardware Configurations
The HYDROVAR Modul Concept consists mechanically of two main parts, the Power Unit
and the Control Card. In its basic configuration (consists only of the Power Unit) the
HYDROVAR can be used as “Basic Inverter” without the need of the Control Card. In that
form the HYDROVAR can be used as a sequence pump in a multi pump system, but also as
a simple soft starter for single pump applications.
By extending this “Basic Inverter” with the additional Control Card, the HYDROVAR is able
to work in different modes and can be extended by the implementation of different
modules.
General Versions:
Basic Inverter – HYDROVAR in its simplest configuration, consists only of the power unit.
Application: Single pump operation as soft-starter, sequence pump in a multi pump system
Master Inverter – Full featured HYDROVAR including the high level Control Card (supports
also the optional modules like the optional “Relay Card” and all special software features).
Application:
- Single pump control including all extended features
- Multi pump system of “Master” and “Basic Inverters” (up to 8 pumps)
- Multi pump system equipped with up to 8 “Master Inverters”
- in combination with the optional “Relay Card” up to 5 fixed speed pumps can be
controlled with this kind of configuration
Single Inverter – HYDROVAR with Control Card developed only for Single pump operation
and less features in comparison with the Master Inverter. Additionally the Single Inverter
isn’t able to support any optional Modules like the Relay Card.
Application:
- Single pump control
3.2 Operation Modes
3.2.1 Actuator (for single pump operation only!)
In this mode the HYDROVAR operates as an Actuator with external speed signal or
switching between 2 programmed frequencies by using the corresponding digital input.
For this application the HYDROVAR operates like a standard frequency converter when an
external controller is used.
!!! Please consider that this mode is only possible by using a HYDROVAR Master or
Single Inverter and is limited for single pump operation only!!!
3.2.2 Controller
This mode should be selected if only one HYDROVAR pump is in operation and there is no
connection to any other HYDROVAR via RS485 interface.
9
3.2.3 Cascade Relay
One pump is fitted with a HYDROVAR “Master Inverter” and up to 5 full speed slave pumps
can be switched ON and OFF on demand. For this purpose an additional relay card with 5
relays is used in the “Master Inverter”. Each Relay can be activated or deactivated
depending on how many pumps are connected.
Basically an external panel is needed for all the motor relays, because the relays in the
HYDROVAR can’t switch the pumps directly as they are just used as switch contacts.
Also an automatic change over of the fixed speed pumps to provide even wear and achieve
even operating hours is possible in this mode.
This configuration would be a simple alternative compared with other solutions using
VFD’s on each pump, but in any case care has to be taken due to the lower operating
safety of such a system.
Application Example
Booster sets up to 6 pumps where only one pump is speed controlled by the HYDROVAR
and the others are fixed speed (1 HYDROVAR Master Inverter+5 fixed speed). This should
be the standard configuration when the additional “Relay Card” is used.

3.2.4 Cascade Serial
In this mode there are various possibilities to combine the different versions of the
HYDROVAR, which will be explained on the following pages.
In general each of the pumps is equipped with a HYDROVAR unit. All units are connected
via the RS485 interface and are communicating via standard MODBUS-Format (fixed with
9600 Baud, RTU, N81).
To realise a fully controlled system at least one “Master Inverter” is needed, the other
pumps could be fitted just with a “Basic Inverter”.
The controller in the “Master Inverter” is informed about the status and a possible failure
of the “Basic Inverters” all the time. All possible failures will be indicated on the Master
unit, including also the date and real time when the failure happened.
The completecontrol will be done via the “Master Inverter” every time, but also an
automatic change over of the lag pumps to provide even wear and achieve even operating
hours will be possible .
If the Control Card of a “Master Inverter” fails, each of the “Basic Inverters” can be
manually started by an external switch (manual operation) in order to ensure an
“emergency operation” of the system.
Application Example
Each pump of the system (extended up to 8 pumps) is equipped with a HYDROVAR unit (at
least one “Master Inverter” and the others can be “Basic Inverters” in order to ensure a
proper control of the system) which are connected via the serial interface.
The combination of the different HYDROVAR units that are used in a multi-pump-system
depends on the system requirements (i.e. in a 6 pump system 2 “Master Inverters” can be
used due to safety reasons and 4 “Basic Inverters” without Control Card – or just any other
configuration)
Minimum requirement: 1 “Master Inverter” and the others equipped with “Basic Inverters”
RS 485
connection
extended up
to 8 pumps
11
To increase the operating safety of such a system, also a second “Master Inverter” could be
used:
RS 485
connection
extended up
to 8 pumps
Full-featured Possibility: Each pump is equipped with a “Master Inverter”
RS 485
connection
extended up
to 8 pumps
In this mode it is possible to run all pumps in multi-controller mode and synchronous mode
as well!
This configuration allows each pump of the system to become a lead pump. This ensures a
proper operation if one “Master Inverter” fails, either another one is used to take the “full
responsibility” and a steady control of the system. That ensures that the operating hours of
each separate pump will be on the same level to ensure even wear of the pumps.

Make sure that the HYDROVAR’s electrical data match those of the electric
pump. Improper combinations may cause malfunctions and fail to ensure the
protection of the electric motor.
The rated current of the motor must be lower than the rated current of the HYDROVAR
to prevent overheating or shutdown due to “OVERLOAD”.
The max. output current of the HYDROVAR could reach 110% of the nominal current for
max. 60 sec. before the error “OVERLOAD” will occur.

The EMC requirements differ between two environments which depending on the intended
use.
• First environment – class B (EN 61800-3: Class C2)
Environment that includes domestic premises, it also includes establishments directly
connected without intermediate transformers to a low-voltage power supply network
which supplies buildings used for domestic purposes.
E.g. Houses, apartments, commercial premises or offices in a residential building are typical
examples of first environment locations.
Be careful
: The relevant EMC regulations for which the HYDROVAR is tested in the first
environment consider that the HYDROVAR is a restricted available product. That means the
voltage of the inverter is less than 1 000 V, it is neither a plug in device nor a movable
device and, when used in the first environment, is intended to be installed and
commissioned only by a person or an organisation having necessary skills in installing
and/or commissioning power drive systems, including their EMC aspects.
• Second environment – class A (EN 61800-3: Class C3)
Environment that includes all establishments other than those directly connected to a low
voltage power supply network which supplies buildings used for domestic purposes
E.g. Industrial areas, technical areas of any building fed from a dedicated transformer are
typical examples of second environment locations.
The HYDROVAR complies with the general EMC regulations and is tested according
to the following standards: EN 61800-3/2005
EN 55011 (2002) Disturbance voltages / Disturbance field strength

Power Unit
In its standard form it will be used as Basic Inverter or as simple soft starter in a
single pump application!
When using a Master configuration the power unit is fitted with an additional
control card!
To remove the HYDROVAR – cover, the 4 fastening screws must be opened.
o Ensure that there is no water on the unit before you open the cover.
• The HYDROVAR has to be positioned on the motor fan cover (check if the mounting of
the motor fan cover is done properly).
• Try to centre it as good as possible using the rubber centre bit.
o
If the HYDROVAR is mounted on a motor with plastic fan cover, a stainless steel
mounting ring must be used.
• The HYDROVAR is installed on the motor fan cover by using the mounting brackets, the
four screws and the related washers.
• The HYDROVAR has to be centred and then the four screws must be tightened.
• Tighten each fastening screw until the two bottom teeth in the brackets start to grip the
fan cover.
• After the electrical components are connected, the top cover on the HYDROVAR can be
mounted and tightened by the four fastening screws.
o Make sure of a good connection of the ground wire.
o Control the gasket of the HYDROVAR before tighten the fastening screws.
o Ensure that the mounting of the cable glands is done properly and use closing
glands for cable-bushings which aren’t used.

9 Electrical installation and wiring
All installations and maintenance have to be performed by properly
trained and qualified personnel with proper tools!!
Use personally protection equipment.
In case of a failure, the electrical power has to be disconnected or
switched off. Wait at least 8 minutes for capacitor discharge before
servicing the HYDROVAR.
Otherwise it can cause shock, burns or death.
9.1 Means of protection
Ask your power supply company which means of protection are required.
Applicable:
• protective earthing
• AC and DC residual current operated protective devices (RCD)
• TN systems
Protective earthing:
• Please note that a current to earth can occur due to the capacitors in the input filter.
• A suitable protection unit has to be selected (according local regulations).
Residual current device (RCD/RCCB):
• When using a RCD, make sure that it also releases in the event of a short circuit inside
the DC-part of the HYDROVAR to earth!
o single phase HYDROVAR => use pulse sensitive RCDs
o three phase HYDROVAR => use AC/DC sensitive RCDs
• The RCD has to be installed according local regulations!
Automatic circuit breaker:
• Use automatic circuit breaker with C-type characteristic curve
• Rating of the line-protection (see chapter Technical Data)
Internal protective devices of the HYDROVAR:
• The malfunctions short circuit, under- and over-voltage, overload and the
overheating of the electronic components are monitored internally by the
HYDROVAR.
External protective devices:
• Additional protective functions like motor overheat and low water protection, are
controlled by external equipment.
24
9.2 EMC-electromagnetic compatibility
To ensure the electromagnetic compatibility the following points must be observed for
cable installation:
Earth / ground to ensure EMC
• Protection earth
It is important to connect the HYDROVAR to PE, because of the earth leakage
current.
• HF earth connection
Ground cables should be as short as possible and with lowest impedance.
Signal cables
Control and signal cables should be screened types to prevent disturbances from outside.
The screen should be only connected to ground on one side; otherwise it is possible that
the screen has a ground current. The screen should be extensively connected with cableclips to HYDROVAR GND (use pre mounted cable-clips).
Pre-mounted cable-clips
To connect a screen with lowest impedance to ground, remove the isolation from the
signal cable and connect the screen extensive to ground.
Signal cables must be installed separate from motor- and power- supply cables
If signal cables are installed in parallel to power supply cables (motor cables) for a longer
distance, the distance between these cables should be more than 200mm.
Don’t cross power cables with control cables-if this is not possible, cross them only in an
angle of 90°.
25
Motor cables
To ensure the EMC compatibility and minimize noise level and leakage currents, keep the
motor cable as short as possible.
Additional component line choke (coil)
Line coils are available as an option and should be mounted between the HYDROVAR and
the main fuse. The Line coil should be as near as possible to the HYDROVAR.
Advantages:
• better efficiency
• reduction of harmonic currents
For the following applications additional line chokes are strongly recommended:
• high short circuit currents
• compensation-plants without a coil
• asynchronous motors which are responsible for a voltage drop >20% of the line
voltage
EMC summary
• Install potential equalization according local regulations
• Don’t install the power-cable in parallel to signal-cables
• Use screened signal-cables
• Connect only one end of the screen of a signal-cable to ground
• If screened motor-cables are used, both ends of the screen have to be connected to
ground
• Motor-cable as short as possible
• “Pigtails” should be prevented
9.3 Recommended Cable Types

be connected to the power unit. They must be connected to X1/PTC in serial and will stop
the HYDROVAR in case of a failure! (Also a low-water switch or any other protective devices
can be connected to these terminals!)
If there aren’t connected any external protective devices or they are connected directly to
the Control Card when using a Master Inverter, bridge terminals X1/PTC, otherwise the
HYDROVAR can’t be started.
30
9.4.3.1 Solo Run
The Terminals X1/SL are used to release a Basic Inverter (when used in a multi-pump
application) when the communication to the Master Inverter fails, or even the Master
Inverter itself fails, or in case the Basic Inverter is just used as simple soft-starter.
• At opened contact X1/SL the HYDROVAR works in standard operation. So a Basic Inverter
only starts up, if it is released and requested by a Master Inverter via the serial RS485Interface.
• When contact X1/SL is closed the HYDROVAR starts up to pre-selected MAX. FREQUENCY
[0245] using Ramp 1 and 2 and even the Fast Ramps FminA and FminD.
(X1/PTC must be closed too - all external connected safety devices are still active)
A manual start up is always possible, even the HYDROVAR is equipped with a Control Card.
For example, if it is necessary because of safety reasons to operate the Basic Inverters when
the Master Inverters fail, it is possible to equip this terminal with an AUTO/MANUAL switch.
Connection Example

If the HYDROVAR is used as Basic Inverter in a multi-pump system, the internal interface on
the power unit is used for the serial RS-485 connection to the other HYDROVAR in the
system. (Be careful: Internal Interface is not active for Single Inverter configuration!)
……. Parameter not available for a HYDROVAR Single Inverter
The internal RS-485 Interface on the Power Unit is used for the communication between
up to 8 HYDROVARs in a multi-pump system (Minimum 1 Master Inverter). For the
connection to each HYDROVAR via the RS-485 interface the terminals X2/1-3 on the power
unit can be used twice. Even the terminals X4/4-6 on the Control Card, can be used.
RS485 – Internal Interface
Mechanical connection of the Terminal:
- Use recommended Cable type (see chapter 9.3)
- Strip the end of the used wire (about 5 … 6mm)
- push down the orange wedges by using a small screwdriver
- insert the stripped wire
- remove the screwdriver to fix the wire
- To remove, push down the orange wedges and pull out the wire!
Connection example using one Master- and three Basic - Inverters:

9.4.3.2 Addressing
When using the Cascade Serial Mode in a Multi-pump-application where more than one
Master Inverters, or additional to Master Inverters also Basic Inverters are used, the right
Address must be set to guarantee the correct function of this system.
Master Inverter – The desired Addresses of the Master Inverter have to be set via
HYDROVAR-Software. So for all Master Inverters the below shown Dip-Switch on the Power
Unit must be set to Address 1 (Default setting).
Basic Inverter – When using a Basic Inverter in a Multi-pump-system it is necessary to set
the Dip-Switches on the Power unit in order to get a separate address for each Inverter
within your pump group. (pls. consider reserved Addresses for the Master Inverters)
for example:
Multi-pump-system with 3 Master and 4 Basic Inverters
• Set Address 1-3 for the Master Inverters via appropriate Software Parameters
(See Submenu RS485-INTERFACE [1200])
• Address 4-7 for the Basic Inverters via Dip-Switch
The pre-selected Address is also responsible for the pump sequence.
Switch 1 Switch 2 Switch

Switch 4 is not used!
Setting of the correct Address:
oThe HYDROVAR must be disconnected from power supply at least for 8 minutes
before removing the top-cover (open four fastening screws)!
o Find the Dip-switch which is placed on the power unit (see Picture next page!)
o Set the desired address for each Inverter
e.g. Address 4 -> Switch 1 is set to OFF
Switch 2 and 3 are set to ON
o Mount the cover on the HYDROVAR and tighten the four fastening screws
o Reconnect HYDROVAR to power supply

9.4.4 Control Unit
Regarding the Hardware configuration of your HYDROVAR there are available two different
Control Cards.
The control unit of the HYDROVAR Master Inverter basically consists of the Control Card
and the additional boards which are connected to the Control Card via slot connectors. This
configuration is able to support all special software features and optional Boards.
The second available control card included in the HYDROVAR Single Inverter is developed
just for single pump operation. This control card also doesn’t support any additional
boards and includes just the minimum necessary software parameters.
9.4.4.1 Control Card – HYDROVAR Master Inverter
The Control Card is connected to the power unit with a
ribbon cable on terminal X8.
• The display is connected to terminal X9
(the connection depends to the installation position).
• The connection terminals X6 and X7 can be used if optional boards are available.
e.g. The additional Relay Card can be connected to the Control Card at connection slot
X6.

RS-485 – Internal Interface RS-485 - User Interface
The internal RS-485 Interface is used for the communication between up to 8 HYDROVARs
in a multi-pump application. For the connection of each HYDROVAR via the RS-485
interface the terminals X4/4-6 on the Control Card, and even the terminals X2/1-3 on the
power unit can be used. (Connection example: using one Master- and three Basic -
Inverters.)
By using the RS-485 – User Interface on the Control Card, one or more HYDROVAR can
communicate via the standardized Modbus-protocol with an external-control-device (e.g.
PLC). This interface can be used for parameterising and controlling the HYDROVAR via
external devices. Also active for HYDROVAR Single Inverter - Configuration.
Do not use the Internal Interface as User Interface and vice versa!

42
Connection example:
The following wiring diagram shows a standard cascade control system where the
HYDROVAR is fitted with an additional Relay card, in selected mode “Cascade Relay”.
To switch the fixed speed pumps via the internal relay card, an external panel for the
contactors of the D.O.L or STAR/DELTA starters (and optional A/0/M – switch) is required.
In the example below 3 fixed speed pumps (motors) are connected to the Relay Card. For
such an application, an optional HAND/OFF/AUTO switch (SW1, SW2, SW3) is
recommended.
- During normal operation the switch is set to AUTO, so the Relay Card of the HYDROVAR
would start and stop the follow-up pumps.
- The “HAND” position allows a manual operation of the pumps.
- If one of the additional switches is in OFF position, the related relay must be disabled in
the submenu STATUS [20] to ensure correct operation of the multi-pump system.

Selection of the Operation Mode
Possible settings: Controller, Cascade Relay, Cascade Serial, Actuator
Controller (Default Setting):
This mode should be selected if only one HYDROVAR Master-Inverter is in operation and no
connection to any other HYDROVAR via RS-485 interface has been done.
Cascade Relay:
S
The standard application for this mode is one Master–Inverter fitted with an additional
Relay-Card, to control up to 5 fixed speed pumps.
There is no connection to any other HYDROVAR via RS-485 Interface.
Advantages: costs, realizing of simple systems
Cascade Serial:
If more than one speed controlled pump has to operate together via the RS-485 interface,
this mode must be selected.
The standard application for this mode is a multi-pump system with up to 8 pumps, each
fitted with a HYDROVAR Master Inverter or a combination of Master and Basic Inverters.
Advantages
: operation safety, switch interval, switching over in case of a failure
59
Actuator: (For single pump operation only!)
The Actuator mode has to be used if an external speed signal is connected and the
HYDROVAR is just used like a standard frequency converter.
In this case, the internal controller is shut off, so the HYDROVAR won’t control the set value
but it is responsible for running the connected motor at a frequency proportional to the
input signal connected to the analogue inputs:
X3/13: Voltage signal input (Required value 1) ⇒ 0 - 10V = 0 - MAX. FREQ. [0245]
X3/15: Voltage signal input (Required value 2) ⇒ 0 - 10V = 0 - MAX. FREQ. [0245]
X3/18: Current signal input (Required value 1) ⇒ 4-20 mA = 0 - MAX. FREQ. [0245]
0-20 mA = 0 - MAX. FREQ. [0245]
X3/23: Current signal input (Required value 2) ⇒ 4-20 mA = 0 - MAX. FREQ. [0245]
0-20 mA = 0 - MAX. FREQ. [0245]
• A manual switching between the analogue inputs is possible by using the corresponding
digital inputs.
• The frequency varies along the programmed Ramps 1 and 2. The functions thermal
protection and external ON/OFF remain still active.
• The functions “External ON/OFF”, “Motor Overheat”, “Lack of water” and all other
internal protections still work.
In the Actuator Mode it is also possible to work with a pre-selected frequency for a manual
control of the HYDROVAR. It is possible to set two different frequencies in the Submenu

Ramp settings:
• Time setting of the Ramps influence the control of the pump and shouldn’t be changed
at standard operation.
• The fast Ramps 1 and 2 are determined by the type (power) of the HYDROVAR and the
type of the pump.
(Default = 4 sec.; depending on the power of the HYDROVAR they should be increased
up to 15s for higher power ratings)
,
• The Ramps 3 and 4 determine the speed of the internal HYDROVAR controller and
depend on the system, which has to be controlled. (Default = 70 sec.)
• The Ramps FminA and FminD are used for a fast start-up and shut off time. These
parameters especially should be used for applications where pumps or other devices are
powered, which shouldn’t work below a determined frequency for a certain time. (to
prevent damages or decrease abrasion)

pumps, in order to provide even wear and achieve even operating hours of the pumps.
The Switch Interval is valid for HYDROVAR Master Inverters only (connected via the RS-485
interface) and using operation mode Cascade Serial.
Synchronous Control
By using the synchronous control mode all pumps in the system maintain the set
pressure by running at the same frequency.
S
The 2nd pump starts, when the 1st pump reaches the ENABLE FRQ. [0515] the system and
pressure drops below ACTU.VAL.DEC. [0510] -> both pumps will run synchronously.
The follow-up pump will stop, when the frequency drops below the set SYNCHR. LIMIT
[0560]. This function creates a hysteresis effect which prevents the follow-up pump
against a frequent on/off operation.
To find out the right setting:
• Start the first pump in JOG Mode [62]; Increase the frequency till you reach the required
value. Check the frequency ( = f
• Set the synchronous limit (f
) at zero consumption
0
+ 2..3 Hz)
0
• Set the synchronous window between 1 or 2 Hz
(depending on the pump curve and set point).

Frequency limit for synchronous regulation
Possible settings: 0 .0 Hz - Max. Frequency
This parameter is used for switching off the first follow-up pump in synchronous mode.
So if the frequency of both pumps goes below this selected value, the first follow-up
pump stops.

This Parameter determines the switching order when Master and Basic Inverters are
Used together. In such a case you have to choose if the Master or the Basic Inverters should
be switched on first.
ON- All Master Inverters in the System are released (unless it is stopped by a failure or
manually) before the first Basic Inverter gets released.
For example: Address 1-3 ..... Master Inverters
Address 4-8 ….. Basic Inverters

shown.
The internal counter of the automatic error reset is being decreased after each operating
hour, so if an error could be reset after 3 restarts, there are 3 further restarts possible after
one hour, 4 after two hours and 5 automatic restarts after 3 operating hours.
A manual reset can be done by switching the External ON/OFF (X3/7-8).
Not each error can be reset automatically.

11 Failure Messages
If the HYDROVAR is being stopped by an error (warning), both the
HYDROVAR and the motor remains under voltage.
So before any work can be carried out on the electrical or mechanical part of
the system, the HYDROVAR must be disconnected from power supply.
It has to be differed between warnings and errors:
•Warnings are shown on the display (and even by the red failure led) but it is possible
that the HYDROVAR keeps running (depends to the different warnings).
If a warning is active and the cause can’t be remedied during 20 seconds in most cases
an error will be shown.
•Errors are indicated on the HYDROVAR and by the red failure LED placed on the
control panel, and the connected motor is stopped immediately. All errors are shown
on the Display and saved in the Error Memory including date and time when the
failure happened.
The below mentioned points describe each error which can occur on the HYDROVAR (even
on the Master and the Basic Inverter). Also the possible countermeasures to reset these
errors are described.
• Please notice that an automatic error-reset can be activated in SUBMENU ERRORS to
reset an occurred failure automatically for 5 times. For more information about this
function see parameter ERROR-RESET [0615].
• All error signals and warnings can be also indicated at the two Status-Relays on
terminals X5/1-2-3 or X5/4-5-6 depending on the configuration.

to cut the power supply for > 60 seconds.
Reset:
A reset of all other errors can be done by open/close the START/STOP_PTC
input (X1/SL) on the power unit.
If the Basic Inverter is used in combination with a Master Inverter, each failure can be
indicated on the Master Inverter too and will be saved in the failure memory including date
and time when the failure happened.

Booster unit
Problem: no stop of the HYDROVAR
Parts to check Solution
• existing demand
• non return valve is not closed
• pre charge pressure in the pressure tank
• no correct settings of WINDOW and
RAMPHYSTERESIS
• shut down Ramp too slow
• suction line too long
Control on constant flow
• check pipes and valves
• change non return valve
• adjust according the diagram
(Look at chapter 2.1)
• set WINDOW [0310] (ca.10%) and
HYSTERESIS [0315] (80-50%)
• set RAMP 2 [0220] to 4...15 sec.
• the MINIMUM FREQUENCY [0250] should be
activated for pressure increase at 0 demand
