1.2 System description
™
The Nexicon is a programmable and extendable
monitoring and control platform. Nexicon
signed as a modular system where each module is
configured to monitor or control different assets or
set of features.
Communication between the modules in the system
is made through the backplane.
The communication to a web interface or to a SCA-
DA system is made through the application manag-
er. The communication to a Xylem HMI or a service
tool is made through the backplane supply module.
This image shows an example of a configuration of a
controller for a pumping station. The following mod-
ules are seen from left to right: Backplane supply
module, application manager, two pump modules,
and one I/O module. All modules are connected to
the backplane.
2 Installation
2.1 Installation requirements
The safety of any system that includes these mod-
ules is the responsibility of the assembler of the sys-
tem.
The safety instructions must be read before installa-
tion.
• Indoor use. The modules are rated IP20.
• Operating temperature -20°C – +60°C (-4°F –
+140°F)
• For North America and other applicable markets
– The modules must be installed in an industrial
control cabinet.
• IEC requirements
Description
Digital input/output mod-
ule with six inputs and
four outputs
™
is de-
– The modules must be installed in a safety en-
closure with minimum IP54 rating.
• The modules must be installed on a Nexicon
backplane.
• Do not block air vents. Make sure that there is
sufficient air for cooling.
• The modules must be installed in the direction
that is shown in the images.
• Any equipment connected to the modules must
meet local standards and regulations.
• The supply and all connected voltages below
30 V , 60 VDC, or 42.4 V
RMS
with PELV according to EN/IEC/CSA/
UL61010-2-201.
• The maximum current for the terminal blocks is
15 A.
• The system must be powered off before installing
a new module.
• The cables that are connected to the
modules must meet the following requirements:
– 0.2 mm² to 2.5 mm² (AWG 24 to AWG 12)
– Minimum temperature rating + 105°C
(+ 221°F)
– Copper conductors only
2.2 General digital inputs
A general digital input can be configured as active or
passive.
• Configured as active, the digital input must be
connected to GND to activate the related func-
tion. An open input deactivates the function.
• Configured as passive, connection to GND deac-
tivates the related function, while an open input
activates the function.
2.3 Install the I/O module
For images, see the appendix.
The module is installed on a backplane, in any emp-
ty slot to the right of the application manager.
1. Install the module on the backplane.
The spring lock engages with a click.
2. Connect the applicable equipment to the termi-
nals.
3. Attach the cables to the cable tie holder.
3 Operation
3.1 Startup and operation
Pumps, switches, sensors, and other equipment are
installed according to separate instructions, and then
connected to the Nexicon
is connected to the application manager or to the
backplane supply module. When all the modules are
installed and energized, the Setup Wizard starts au-
tomatically.
