1. Introduction
Thank you for choosing a Bianco nXt-Protect single pump control and protection module.
The nXt-Protect is a module intended to control and protect an individual single phase
pump. The user can select a control logic sequence to match their application and enjoy the
benefits of superior control and protection for the pumps.
There are 3 primary control logic modes:
•‘Drainage’ where control is concentrated at the source
•‘Boosting’ which references pressure switching on the delivery side for control
•‘Transfer’ which is a mix of source and destination control
The LCD screen displays the pump running state and provides the user a wealth of useful
information.
The controller is easy to set up with an initial push button calibration and individual
parameters can be fine-tuned.
A nXt-Protect controller is particularly useful where there is the need to control and protect
pump installations managing the automatic operation through a variety of switching
methods without the need to create a bespoke control solution.
2. Warnings and Cautions
Read the manual carefully before starting
Prior to starting installation or maintenance the controller must be
disconnected from the power supply.
Any changes or modification to the wiring must be carried out by
competent, skilled and suitably qualified personnel only.
A qualified electrician should correctly size and install circuit breakers
to protect the power supply. The fitment of additional surge protection
is recommended as good practice.
Never open the cover while controller is connected to electrical supply.
Disconnect and allow the internal electronics to discharge before
opening the cover
This appliance is not intended for use by persons (including children)
with reduced physical, sensory or mental capabilities, or lack of
experience and knowledge, unless they have been given supervision or
instruction concerning use of the appliance by a person responsible for
their safety. Children should be supervised to ensure that they do not
play with the appliance.
Ensure the controller is a suitable size for the pump motor (see
Section 6, Page 7: Technical Data). Size according to full load
current amperage.(P1 power)

5. Modes of Operation
On the main PCB there is a 2 position ‘Dip
Switch’
To alter the control logic to suit an application,
the installer must select the appropriate switch
position.
After selecting the desired switch position, cycle
the controller power to apply the setting.
Binary
Switch position
Control logic - Applications
1
‘Drainage’ Mode where the level control input is managed by
a flexible float on the pump.
2
‘Pressure Boosting’ Mode. Main control via (N/C) pressure
switch. Supports run / no run level protection at the source
via floats or probes.
3
‘Drainage’ Mode where the control inputs (generally level
floats or probes) are located at the source.
4
Default
Mode
‘Transfer’ Mode. Main control via control inputs (floats or
probes) at destination or by a pressure switch on the delivery
line. Supports run / no run level protection at the source.
4
Sensorless time control
When first powered on the nXt-Protect will display
the current dipswitch operating mode (binary code),
the hardware and the software version.

7. Display con’t
The nXt-Protect controller operates according to pre-programmed logic applied to each
‘mode’.
Changing the Dip Switches inside the controller then cycling the power will activate the
selected logic mode.
Examples of common applications are detailed later in this manual but with an
understanding of how the controller responds to various inputs in each of the modes the
controller can be used for application other than what is suggested.
The appearance of the front display changes according to each mode and provides a visual
indication to the state of the input signals.

Avoid installing the nXt-Protect where it could experience the following conditions:
i. Where there is significant vibration and/or mechanical shock.
ii. Where it could be exposed to corrosive liquids or gasses, or to flammable
materials, solvents etc.
iii. Extreme heat and cold. Operating range -25oC - 55oC.
iv. Protect the controller from rain, moisture, humidity or dust

8. Electrical Connections
Always use an electrical outlet that is protected by Residual Current Device
(RCD) Safety Switch with a trip current of 30mA or less. A Safety switch is
required by Australian/New Zealand Standard AU/NZS 60335.1-2011.
All high voltage wiring must be connected by a suitably qualified technician.
The nXt-Protect 1-22 has an internal cavity to
hold an external start capacitor. This is
especially useful when protecting and
controlling ‘3 wire’ single phase bore pumps.
Note that nXt-Protect is intended to control a standalone single pump only.
If the installation must connect to a BMS or must operate an external alarm, enquire about
nXt SPC/DPC controllers
It is the responsibility of the installing electrical technician to ensure that the
cable cross section (mm2) meets the requirements of AS/NZS 3008; taking
into consideration the cable type, the cable length, the current draw and
other relevant factors.
If in doubt online resources exist i.e. Cable Size Calculator AS/NZS 3008 or seek advice
from an electrical engineer or other suitably qualified person(s)
