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)

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

10 BIA-nXt-PROTECT1 Instruction Manual
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)

BIA-nXt-PROTECT1 Instruction Manual 11
9. Parameter Calibration
The pump must be able to pump water to enable correct calibration.
Calibrated without water, overload and pump stalled errors may occur later.
Calibration can be performed automatically as detailed in the shortcuts on
page 3. Alternately the user can enter Underload, Overload and Pump Stalled
Amperages at Parameters 001, 002 and 003
Always perform a fresh calibration after installing a new pump, or when
reinstalling an existing pump following maintenance.
Either erase the existing calibration or manually program Parameters 1 -3.
Controller operation is managed using the
buttons on the front cover and a sequence of
short, long and combination button presses.
To access parameter settings the controller should be in its Manual operational mode and
the pump should NOT be running.
Press and hold STORE/SET for 5 sec to enter the parameter menu.
To enter a parameter, press the STORE/SET button. This will display the current value for
the parameter.
●Press the START/STOP button to increase a value.
●Press the AUTO/MANUAL button to decrease a value.
To store the value and return to the main menu press STORE/SET button.
To store all changes and exit the parameter menu press the STORE/SET button
Pump current draw MUST be greater than 1 amp for Auto Calibration to be successful.
Grinder / Macerating Pumps
Manually programming the nXt-Protect around the pump nameplate Full Load Current
allows the pump to generate maximum torque.
This may be a preferred alternative to calibration around the ‘normal’ hydraulic loading
current value in situations with heavily contaminated liquids.

BIA-nXt-PROTECT1 Instruction Manual 13
nXt-Protect controllers are a cost
effective, reliable means to provide
better control and protection without
the need for costly bespoke
switchboards
The following quick guides provide
information regarding common
applications.
The pumps illustrated in the following
quick guides are mostly submersible
type but the nXt-Protect controller is
not limited to this type of pump.
With an understanding of how the
controller responds to various inputs in each of the modes the controller can be used for
applications beyond what is suggested.
For example, the controller can be connected in series with a VFD controlled pump to
provide additional control inputs or to utilise the nXt-Protect controller delay times.
For even greatly flexibility in your installation the nXt-Protect controller can be used as a
‘module’ in a more complex control environment.
Floats
3 wire’ floats allow for NO or NC wiring.
Connecting to the
controller using the
black and brown wires
the circuit is closed
when the float is up,
open circuit when the
float is down.
For greater differential,
dual floats can be
attached on the source
inputs 1, 2 and 3.
When using a single
float on the source
input terminals #2 and
#3 need to be bridged

14 BIA-nXt-PROTECT1 Instruction Manual
11. Quick guide: Transfer – source/destination control
Default mode - As Supplied
Pump On/Off operation is requested by a normally closed float or probes at the
destination or a pressure switch in the delivery line.
A normally closed float switch at the source controls whether the pump will run or not
depending on the liquid level.
Set the dip switches on
the main PCB and cycle
the power
In situations where the destination is a significant
distance from the source it is possible to control
by fitting a normally-open pressure switch to the
delivery line OR to use a remote wireless sensor
to trigger a switched input.
Connect across #4 and #5

BIA-nXt-PROTECT1 Instruction Manual 15
12. Quick guide: Drainage Mode, float connected to pump
The pump On/Off operation is controlled by the float fitted to the pump.
The Controller provides additional protections excluding dry run protection.
A float connected to the controller can provide high level alarm function
Parameter 001 must remain set to 0.0A to prevent underload alarming when the pump float
interrupts pumping operation
Set the dip switches on
the main PCB
and cycle
the power

16 BIA-nXt-PROTECT1 Instruction Manual
13. Quick guide: Drainage Mode, external control inputs
A pump with its own float can be used in this
configuration so long as the operational level of
Pump Stop Switch #1is HIGHER than the
float attached the pump.
Switched input - bridge terminals 5/6 and 2/3.
Pump switches on when the Pump Start switch 1/3 is in the On (Up) position
Pump runs until the Pump Stop switch 1/3 is in the Off (Down) position
High-Level alarm triggers when the High Level alarm switch 4/6 is in the On (Up) position.
The alarm will turn off when the Hi Level alarm switch 4/6 in in its Off (Down) position.
The pump will continue to run until the Pump Stop switch 1/3 is in the Off (down) position
See page 13 for wiring twin control floats to achieve greater switching differential
Set the dip switches on
the main PCB and cycle
the power

BIA-nXt-PROTECT1 Instruction Manual 17
14. Quick guide: Pressure Boosting
Pump On/Off operation is controlled via a pressure switch on the delivery line.
Additional (optional) run/no run protection can be fitted at the source
Or employ probes at the source
Set the dip switches on
the main PCB and cycle
the power

18 BIA-nXt-PROTECT1 Instruction Manual
15. Quick guide: Sensorless Time control
In Auto mode, any a ‘normal’ START REQUEST actives the timer(s) 009 / 010 until that start
request is terminated.
The next start request resets the timer count
008 00 Timer control (auto mode) – Parameters 009 – 101
00 = inactive
01 = active
009 5 min
Pump run timer: range 0 – 254 min
In Auto mode the pump will run for the time set then stop and
consider parameter 010 value
An input requesting the pump to start after stopping takes priority and
resets the timer count
010 5 min
Pump Stop timer:
range 0 – 254 min
In Auto mode having turned off at parameter 009 value the pump will
remain off for the parameter 010 value then restart running for
parameter 009 value etc
Application example: A low yielding bore controlled by a pressure switch.
•The pump starts on the pressure switch input but through experience, the customer knows it
can only run for 10 mins before it will run dry and then will need 20mins for the water to
recover.
•Set 009 to 10 minutes, and 010 to 20minutes.
•Activated by the pressure switch the pump will run for 10mins, turn off for 20mins then run
again for 10mins etc.
•If the destination tank fills closing the ballcock the pressure switch will turn the pump off
irrespective of the 009 run time.
•The process will start again on next run cycle
In Manual operation mode, the pump can be set running and it will switch off after the time
value at parameter 011 has passed.
011 0 min
Pump stop timer (manual mode):
range 0 – 254 min
In Manual operation mode the pump can be set running and it will
stop after the time set in parameter.

16. Fault Messages
Fault Message Possible Cause Potential Solutions
UNDER V
The actual running voltage is lower
than the calibrated voltage parameter
004. The pump is in an under-voltage
protection state
The controller will attempt to restart
the pump every 5 minutes until line
voltage is restored to normal
If this fault occurs repeatedly, report
low line voltage to the power supply
company
OVER V
The actual running voltage is higher
than the calibrated voltage parameter
005. The pump is in over-voltage
protection state
The controller will attempt to restart
the pump every 5 minutes until line
voltage is restored to normal
If this fault occurs repeatedly, report
high line voltage to the power supply
company
PUMP STALLED
The pump motor running amperage
has exceeded the normal (calibrated)
running amperage by more than
parameter 003
This could be due to physical
jamming or a mechanical issue.
If the pump stalled error occurs
repeatedly at commissioning check
the controller rating is matched to the
pump
Pump Stalled is a ‘critical error’ and
will not automatically reset.
Isolate the power supply and inspect
the pump for anything which has
caused the sudden increase in load
OVER LOAD
Pump motor running amperage
exceeds the normal (calibrated)
running amperage by more than
parameter 002
Isolate the power supply and inspect
the pump for anything which is
causing the pump to draw more
amperage than the initial calibration
value
UNDER LOAD
Pump motor running amperage is less
than the normal (calibrated) running
amperage by more than parameter
001
Under-load is sometimes referred to
as Dry-run protection as a pump
motor will draw less current when
there is no load.
OPEN PHASE The power supply has lost power. Check fuses and wiring.
PUMP NO
CALIBRATION Calibration not complete Check the calibration.
Pump draw must exceed 1 amp
