(2) diaphragm tank (5) check valve or ball valve (8) pressure transducer
All plumbing work must be performed by a qualied technician. Always follow all local, state and provincial
codes.
A proper installation requires a pressure relief valve, a ¼" female N.P.T. threaded tting for the pressure sensor,
and properly sized pipe. Piping should be no smaller than the pump discharge and/or suction connections.
Piping should be kept as short as possible. Avoid the use of unnecessary ttings to minimize friction losses.
Some pump and motor combinations supplied with this system can create dangerous pressure.
Select pipe and ttings according to your pipe suppliers’ recommendation. Consult local codes for
piping requirements in your area.
All joints must be airtight. Use Teon tape or another type of pipe sealant to seal threaded connections. Use
caution when using thread sealant as any excess that gets inside the pipe may plug the pressure sensor.
Galvanized ttings or pipe should never be connected directly to the stainless steel discharge head or casing as
galvanic corrosion may occur. Barb type connectors should always be double clamped.

Hazardous
Pressure
CAUTION
SYSTEM DESIGN
Pressure Tank, Pressure Relief Valve and Discharge Piping
Use only “pre-charged” tanks on this system. Do not use galvanized tanks. Select an area that is always above
34º F (1.1º C) in which to install the tank, pressure sensor and pressure relief valve. If this is an area where a water
leak or pressure relief valve blow-off may damage property, connect a drain line to the pressure relief valve. Run
the drain line from the pressure relief valve to a suitable drain or to an area where water will not damage
property.
Pressure Tank, System Pressure
Sizing – A diaphragm tank (not included) is used to cushion the pressure system during start-up and shut-down.
It should be sized to at least 20% of the total capacity of your pump. Example: If your pump is sized for 100 GPM
then size your tank for at least 20 gal. total volume, not draw down. Pre-charge your bladder tank to 15-20 PSI
below your system pressure. The controller is pre-set for 50 PSI at the factory. Therefore a 35-40 PSI pre-charge in
your tank would be required. Use the higher tank pre-charge setting if the system drifts over 5 PSI at a constant
ow rate. NOTE: Pre-charge your tank before lling with water!
CAUTION
Maximum working pressure of HydroPro diaphragm tank is 125 psi.
Installing the Pressure Sensor
The pressure sensor requires a ¼" FNPT tting for installation. Install the pressure sensor with the electrical
connector pointing up to avoid clogging the pressure port with debris. Install the pressure sensor in a straight
run of pipe away from elbows or turbulence. For optimum pressure control install the pressure sensor in the
same straight run of pipe as the pressure tank. Ensure the pressure sensor is within 10 feet of the pressure tank.
Installing the pressure sensor far away from the pressure tank may result in pressure oscillations. Do not install the pressure sensor in a location where freezing can occur. A frozen pipe can cause damage to the pressure
sensor.
The pressure sensor cable is 30' as standard. The cable can be shortened for a cleaner installation. Longer cable
lengths are available, consult factory. Maximum recommended pressure sensor cable length is 300 feet. Avoid
leaving a coil of pressure sensor cable as this can induce unwanted transient voltages and noise into the system.
Do not run the pressure sensor cable alongside the input or output wiring. Maintain a distance of at least 8”
between the pressure sensor cable and input or output wiring.
WARNING
Discharge pressure within the piping system prior to removing pressure transducer or disconnecting any part
of the piping system. Open a valve until pressure on an external gauge reads 0 psi.

PRODUCT OVERVIEW
Section 3
3.1 Hardware Congurations
The HYDROVAR variable speed drive consists of two separate components: the power unit and the control card.
In its basic conguration (consisting of only the power unit) the HYDROVAR can be used as a Basic Inverter. In
that conguration the HYDROVAR can be used as a sequence pump in a multi pump system, or as a simple soft
starter for single pump applications.
By extending this Basic controller with the additional control card, the HYDROVAR is able to work in different
modes and can be used for multipump applications.
Three types of drives are available. They are each capable of different levels of control. They are:
Master controller:
• Full variable speed controller of itself in a single pump conguration, with more features than the Single
controller
• Full variable speed control of the attached motor and up to 7 additional Master or Basic controllers.
• Full variable speed control of the attached motor and on/off, xed speed control of up to 5 additional pumps.
(This requires an additional relay card.)
Basic controller:
• Single pump soft start control
• Full variable speed control when connected to a Master controller
Single controller:
• Full variable speed control of a single pump with fewer features than the Master controller
3.2 Modes of Operation
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.
NOTE
This mode can only be programmed with a Master or Single controller, and is for single pump systems
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.
→ Typical single pump operation
3.2.3 Cascade Relay
One pump is tted with a HYDROVAR Master controller and up to 5 xed speed pumps can be switched ON
and OFF on demand. For this purpose an additional Relay Card with 5 relays is used in the Master controller.
Separate motor starters are needed for each motor relay, because the relays in the HYDROVAR are control
contacts only.
Lead/Lag switching of the xed speed pumps to provide even wear and achieve even operating hours can
be programmed in this mode.
This conguration is a cost effective alternative compared with other solutions using VFD’s on each pump,
but additional equipment is required, and you only have xed speed control of the pumps.
7
PRODUCT OVERVIEW
Application Example
Booster sets up to 6 pumps where only one pump is speed controlled by the HYDROVAR and the others are
xed speed (1 HYDROVAR Master Inverter+5 xed speed). This should be the standard conguration when
the additional Relay Card is used.
3.2.4 Cascade Serial and Cascade Synchron
In these modes each of the pumps is equipped with a HYDROVAR unit. All units are connected and
communicate via the RS485 interface.
At least one Master controller is used. The other pumps can be controlled by Basic or Master drives. The
Master controller continually reads the status and failures of the Basic controllers. All failures are indicated on
the master unit, including the date and time.
The Master controller has complete control of all pumps in the system, including automatic alternation of the
lead and lag pumps, which provides even wear and achieves even operating hours for each pump.
If the control card of a Master controller fails, each of the Basic controllers can be manually started by an
external switch (manual operation) for “emergency operation” of the system.
Application Example
Each pump, (up to 8 pumps), is equipped with a HYDROVAR unit. At least one Master controller will be
connected to up to seven Basic controllers. All units are connected via the serial interface (RS485).
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 or more Master controllers can be used to increase reliability,
and up to 4 Basic controllers
without control card.
Minimum requirement: 1
Master controller and the other
pumps equipped with Basic
controllers.
8
PRODUCT OVERVIEW
To increase the reliability of a system, (in the event of a Master controller failure) a second Master controller
can be used.
Full-featured possibility: Each pump is equipped with a Master controller.
In this mode it is possible to run all pumps in cascade serial mode and synchronous mode as well.
This conguration allows each pump to become the lead pump. This also ensures a proper operation if one
Master controller fails. In this case another HYDROVAR takes control. This ensures that the operating hours of
each pump will be the same to ensure even wear of the pumps.

8.2 EMC – Electromagnetic Compatibility
To ensure electromagnetic compatibility the following points must be observed for cable installation:
Control Cables
General Recommendations
Use shielded cables, temperature rated at 60º C (140º F) or above:
• Control cables must be multi-core cables with a braided copper wire screen.
Double Shielded Single Shielded
Example: JAMAK by Draka NK Cables Example: NOMAK by Draka NK Cables
• The screen must be twisted together into a bundle not longer than ve times its width and connected to
terminal X1-1 (for digital and analog I/O cables) or to either X1-28 or X1-32 (for RS485 cables).
Route control cables to minimize radiation to the cable:
• Route as far away as possible from the input power and motor cables (at least 20 cm (8 in)).
• Where control cables must cross power cables make sure they are at an angle as near 90º as possible.
• Stay at least 20 cm (8 in) from the sides of the drive.
Use care in mixing signal types on the same cable:
• Do not mix analog and digital input signals on the same cable.
• Run relay-controlled signals as twisted pairs (especially if voltage > 48 V). Relay-controlled signals using
less than 48 V can be run in the same cables as digital input signals.
NOTE! Never mix 24 VDC and AC power signals in the same cable.
Motor Wires
To ensure the EMC compatibility and minimize noise level and leakage currents, use the shortest possible motor wires. Use shielded wires only if the total length exceeds 6 feet.)
Line Reactors
Line reactors are available as an option and should be mounted between the HYDROVAR and the main fuse.
The Line reactor should be as close to the HYDROVAR as possible, (max. 12").
Advantages:
• more efcient
• reduction of harmonic currents
For the following applications additional line reactors 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 proper grounds according to local codes and regulations
• Do not install the power wires in parallel to control wires
• Use screened control cables
• Connect both ends of the motor wire screen to ground
• Connect only one end of the control wire screen to ground
• Motor wires should be as short as possible

If these terminals are not used, they must be jumpered, otherwise the HYDROVAR will not start.
8.4.3.1 Solo Run (Hand Mode)
Terminals X1/SL are used to enable a Basic drive (when used in a multi-pump application) when the communication from the Master drive fails, or if the Master drive itself fails, or to use the Basic drive as a soft-starter.
• If the circuit is open between the two X1/SL terminals, the HYDROVAR works in standard operation as
controlled by a Master drive.
• When contact between the two X1/SL terminals is closed, (contact between X1/PTC terminals must also
be closed), the HYDROVAR starts up to the pre-selected Max Frequency, (set via xed speed, (parameter
0245) using ramps 1 and 2 or the fast ramps FminA and FminD).
A manual override switch can be placed between the 2 X1/SL terminals. When the circuit is open, the drive
will work with the Master. When it is closed, the drive will operate manually.

8.4.3.2 Addressing
When using the cascade serial/synchron mode in a multi-pump-application (where more than drive is used),
each drive must be addressed correctly.
Master drive – The address of the Master drive is set using the Hydrovar software. Dip switches are used to
program the Basic drives to a specic address. On all Master drives the dip switches must be set to address 1
(default setting, see below).
Basic Drive – When using a Basic drive in a Multi-pump-system the dip switches must be set to the appropriate address for each drive in the system. The addresses for the Basic drives start after the last address of the
nal Master drive in the system. The S1 switchbank is located on the lower board behind the control panel.
(See pictures below for locations.)
Example:
Multi-pump-system with 3 Master and 4 Basic drives
• Set address 1-3 for the Master Inverters via appropriate software parameters (See submenu CONF
INVERTER [0100] or submenu RS485-INTERFACE [1200])
• Address 4-7 for the Basic Inverters via dip-switches
The pre-selected address also denes the initial pump sequence.
• The HYDROVAR must be disconnected from power supply for at least 5 minutes before removing the top
cover!
• Use the dip-switch on the power unit. (See picture above!)
• Set the desired address for each HYDROVAR
E.g. Address 4 -> switch 1 is set to OFF
switch 2 and 3 are set to ON
• Mount the cover on the HYDROVAR and tighten the four fastening screws
• Reconnect HYDROVAR to power supply
Address 1 (default setting)
(Required setting for the use with control card)
ON
1 2 3 4
Address 8
Switch 4 not used!
8.4.4 Control Terminals
All control wires connected to the control-unit must be screened (See section 8.2 for recommended wire types).
External voltage free contacts must be suitable for switching <10 VDC.
NOTE
If unscreened control wires are used, signal interference may occur and could interfere with
the function of the HYDROVAR.
Do not connect the control card ground to other voltage potentials. All electronic ground terminals and GND of
the RS 485-interface are connected internally.

PROGRAMMING
Controller (Default Setting):
Select this mode when only one HYDROVAR Master/Single Drive is used and there is no connection to any
other HYDROVAR via RS-485 interface.
Cascade Serial:
Selected if multiple HYDROVAR controlled pumps operate together via the RS-485 interface.
The standard application for this mode is a multi-pump system with up to 8 pumps, each controlled by a
HYDROVAR Master Drive or a combination of Master and Basic Drives. Advantages: reliability, lead/lag for
balanced usage and wear and tear, automatic alternation in the event of a drive failure (duty standby).
Cascade Synchron:
The Synchronous Controller mode is similar to cascade serial mode. The difference is that all pumps in the
multi pump system run at the same frequency.
Advantages: In the synchronous mode the pumps can operate in a better efciency range and the system
Actuator: (For single pump operation only!)
Actuator mode is used if a xed speed setting is required or an external speed signal is connected to control the speed of the drive.
In this mode, the HYDROVAR does not control the set value but runs the connected motor at a frequency
proportional to the input signal from the analogue input, or is programmed on the HYDROVAR. The following input signals can be used:

Ramp settings:
• The ramps inuence the rate of change in speed.
• The fast ramps 1 and 2 control the rate of acceleration and deceleration of the drive when the system
pressure is outside the hysteresis window, set at Parameter (0310). Default = 4 seconds. The ramps
should be lengthened, (increased) up to 15 seconds for higher horsepower drives to avoid overload er-
ror.
• The slow ramps 3 and 4 determine the acceleration/deceleration rates of the drive when the pressure is
within the hysteresis window. (Default = 70 sec.)
• The Ramps FminA and FminD are used for start-up and shut off. These parameters allow faster accel-
eration and deceleration and should be used for applications where pumps shouldn’t operate below a
determined frequency for a certain time. (to prevent damages or decrease wear) To adjust the Ramps,
• Rapid acceleration may cause an error (OVERLOAD) during drive startup.
• Slow acceleration may cause a drop in outgoing pressure during startup.

Possible settings: 0 – 250 hours
This parameter allows an automatic change over of the master pump and the assist pumps, to provide
even wear and achieve even operating hours of the pumps.
The switch interval is used for HYDROVAR Master Inverters only (connected via the RS-485 interface) by using operation mode Cascade Serial or Cascade Synchron.
Synchronous Control
By using the synchronous control mode all pumps in the system maintain the set pressure by running at the
same frequency.
The 2nd pump starts, when the 1st pump reaches the ENABLE FRQ. [0515] and the system pressure drops
below ACTU. VAL. DEC. [0510] -> both pumps will run synchronously.
The assist pump will stop, when the frequency drops below the set SYNCHR. LIMIT [0560]. This function
creates a hysteresis effect which prevents the assist pump against a frequent on/off operation.
To determine the correct setting:
• Start the rst pump in JOG Mode [62]; Increase the frequency till you reach the required value. Check the
frequency ( = f0 ) at zero consumption
• Set the synchronous limit (f0 + 2..3 Hz)
• Set the synchronous window between 1 or 2 Hz (depending on the pump curve and set point).

Example for using the Offset function:
Constant pressure system with required value of 70 PSI.
Additionally a ow sensor is connected to the Offset input.

Below 20 GPM the pressure should be decreased to maximum 36 PSI at a ow rate of 8 GPM.
Settings:
Parameter [0910] - Level 1 = 50 = 20 GPM (rst limit where the offset function is active)
Parameter [0912] - Offset X1 = 20 = 8 GPM (xed point according the requirements)

FAILURE MESSAGES
Section 10
NOTE
If the HYDROVAR is stopped by an error (warning), the HYDROVAR and the motor remain
under voltage. Before any work is carried out on the electrical or mechanical part of the
system, the HYDROVAR must be disconnected from power supply for at least 5 minutes.
Difference between warnings and errors:
• Warnings are shown on the display and indicated by the red failure LED. If a warning is active and the cause is
not remedied within 20 seconds an error will be shown and the HYDROVAR stops. Note: Not all warnings will
result in an error.
• Errors are indicated on the HYDROVAR display and by the red failure LED on the control panel. In case of an
error the connected motor is stopped immediately. All errors are shown in plain text and saved in the error
memory including date and time when the failure occurred.
The following information describes the errors which can occur on the HYDROVAR (on the Master/Single and the
Basic Inverter). Additionally the possible countermeasures to reset these errors are described.
• Please note 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 indicated via the two status-relays on terminals X5/1-2-3 or X5/4-
5-6 depending on the conguration. (How to program see parameter CONF REL 1 [0715] and CONF REL 2
[0720].)
