1. CapDRIVE Introduction
CapDRIVE is a variable frequency drive designed to control and protect pumping systems by varying the outputfrequency
to the pump.
CapDRIVE can be applied to both new and existing pumping systems, and provides:
energy and cost savings
simplified installation and an overall lower pumping system cost
longer life of the pumping system and relevant components
improved reliability
CapDRIVE, when connected to any pump, manages the system operation to maintain a certain constantphysical quantity
(pressure, differentialpressure, flow, temperature, etc.) regardless of theconditions of use. Thepump is operated onlywhen
needed thus avoiding unnecessary energy consumption.
CapDRIVE at the same time is able to:
protect the motor from overload and dry running
implementsoft start and soft stop toincrease the systemlife andreduce currentpeaks
provide an indication of current consumption, voltage, and power
maintain a record of run time and display any errors and/or failures reported by the system
control up to two additional pumps at a constant speed (Direct On Line)
connect to other CapDRIVE units for combined operation
Through the use of inductive filters (optional) CapDRIVE eliminates dangerous surges that are inducedin longcables,
making CapDRIVE suitable for control of submersible pumps.
2. Safety Instructions
CAPRARI strongly suggests carefully reading this operation manual before using and installing its products
Any operation (installation, maintenance and repair) must be carried out by trained, skilled, and qualified personnel.
Failure to observe and follow the instructions in this manual may result in dangerousand potentially lethal electric shock.
Pay attention to all standard safety and accident prevention regulations.
The device must be connected to main power supply via a switch to ensure the
complete disconnection from the network before any operation on the CapDRIVE itself
(including visual inspection) and/or on the connected load.
Disconnect CapDRIVE from the main power supply before commencing any work.
Do not remove, for any reason, the cover and the cable plate without having first
disconnected the device from the main power supply and having waited at least 5
minutes.
CapDRIVE and pumping system must be grounded properly before operation.
For the entire period CapDRIVE is powered, high voltage is present on the output
terminals of the inverter whether or not the pump is running.
Tightening all 4 screws on the cover with washers is recommended before powering
the device. Otherwise, there may be a failure to connect the cover to ground, creating
the risk of electric shock or even death.
Avoid any shock or significant impact during transport.
Check the CapDRIVE immediately upon delivery and check for damage and/or missing parts. If either occurs, immediately
notify the supplier.
Damages due to transport, incorrect installation, or improper use of the device will null and void the warranty.
Tampering or disassembly of any component will automatically void the warranty.
CAPRARI cannot be held responsible for any damages to people and/or property due to improper use of itsproducts.

4.1 Protections
The protections required upstream each CapDRIVEsdepends on the type of installation, and local regulations. We
recommend to use overload protection with the characteristic curve of type C and type B circuit breaker, sensitive to both AC
and DC current.
4.2 Electromagnetic compliance
To ensure electromagnetic compatibility (EMC) of the system, it is necessary to apply the following measures:
Always connect the device to ground
Use shielded signal cables by placing the screen at one end.
Use motor cable as short as possible (<1 m / <3 ft). For longer lengths, it is recommended to use shielded cables
connecting the screen at both ends.
Separate signal, motor,and power supply cables.
Note: To enable the restoration of the display screen when there are electromagnetic interference, CapDRIVE
periodically provides some fast "refresh" of the display.
4.3 Installation with long motor cables
With long motor cables it’s recommended to decrease the
commutation frequency from 10 kHz (default) to 2.5 kHz
(advanced parameters). This reduces the probability of
voltage spikes in the motor windings whichmay damage the
insulation.
To prevent dangerous overheating of dv/ dt andsinusoidal
filters it is recommended to set the correct PWM value in
relation to the cable length.
For motor cable lengths up to 50 metersit’s recommended
to place between CapDRIVE andmotor a dv / dt
reactance, available on request.
For motor cable lengths greater than 50meters it’s
recommended to place between CapDRIVE and motor a
sinusoidal filter, available on request.

Make sure the manufacturer that the electric motor is suited for operation in the inverter.
Make sure to properly attach the grid of the auxiliary cooling fan.
Make sure to remove the auxiliary cooling fan if CapDRIVEis coupled to a motor. Failure to do so
creates a high risk ofoverheating the motor and CapDRIVE unit.

5.1 CapDRIVE Installation for constant pressure control
CapDRIVE controls the pump speed tomaintain constantpressure at a set point independent of the water demandin the
system.
A basic schematic is shown below:
5.1.1 Pressure tank
Installation of a pressure tank in the hydraulic system is recommended to compensate leakage of water in the system (or
during minimum water demand) and to avoid continuousstart/stop cycling of the pump (check the appendix for more
information). Selecting the proper volume and pre-charge pressure of the tank is very important; smaller tank volumeswill
not compensate adequately for minimum water usage or leakage, while larger volumes make it more difficult for CapDRIVE
to control the pressure evenly.
Recommended tank volume is equalto the 10% of the maximum water flow of thesystem (expressed in volume unit/min)
Example: if the max water flow is 50 liters/min, the pressure tank should have a capacity of 5 liters
If the max water flow is 20 gpm, the pressure tank should have a capacity of 2 gallons
Pre-charge pressure of the pressure tank should be at least 80% than the set-pressure of thesystem.
Example: if the set-pressure of the system is 4 bar, the pre-charge pressure of the tank should be 3.2 bar
If the set-pressure of the system is 60 psi, the pre-charge pressure of the tank should be 48 psi
5.1.2 Pressure sensor
CapDRIVE requires a pressure sensor with a linear output signal within the range 4 – 20mA. The pressure transducer can
be powered by any range of DC Voltage which includes the value 15 V dc.
CapDRIVE accepts the signal of a second pressure sensor in order to:
realize constant differential pressure (AN1 – AN2).
substitute first pressure sensor when it fails
switch pressure sensor by closing digital input IN2
SENSOR 1 AN1: 4-20 mA (-) signal
+15V: 15 Vdc (+) power supply

6. CapDRIVE Use and Programming
CapDRIVE software is extremely simple to use, but allowsa wide variety of parameters to be set for ideal system
calibration. Setting Parameters are organized in 2 levels:
1: Installer level
A password is required for this level; these parameters are adjustable by trained professionals
Default password: 001
From the menu a different password can be set up.
2. Advanced level
A second and different password is required; improper setting of these advanced parameters could compromise the
integrity and the life of CapDRIVE and pump;
Default password 002
It is possible to set up a different password.
Installer and Advanced levelscan be entered only with the correct password; otherwise, it is impossible to set up
and/or modify anyparameters (they can beonly displayed).
6.1 CapDRIVE display
Screen is a back-lit LCD displaying 2 rows of 16 digits each. Alarms are indicated by an audible signal.
6.2 Initial configuration
When CapDRIVE isswitched on forthe first time, theinitial setting menuis displayed for the initialsettingofparameters to
configure pump characteristics, pressure sensor range, and system characteristics.
If the initial setting procedure is not completed properly, it is impossible to run the pump. Initial setting procedure can be
repeated if necessary.
The initial setting procedure can be repeated (by using the 2rd level password) to reconfigure CapDRIVE or if CapDRIVE is
installed in a different system.

To ensure proper operation of pressure control is recommended to place the sensor near the pump.
To compensate the pressure loss in the pipes (proportional to flow) it is possible to vary the pressure set in a linear
relation with respect to frequency.
It can perform the following test to verify the correct value of compensation:
1. install a pressure gauge away from the pressure sensor
2. open completely the valve
3. check the pressure gauge
--> Set the value of compensation. equal to the difference of the values from the two gauges.
When using a group of pumps, the pressure compensation to be applied to each pump is equal to the total pressure
compensation (when all the pumps are running at full speed) divided by the number of pumps in the group.
