The application manager is the controller in the Nex-
™
icon system.
Main features:
• Control and monitoring of a pumping station
• Connection to supervision systems through field-
bus
• Plug and play functionality as a standard setup
• Configurable for different applications
• Optional programming with CODESYS
• A real-time clock (RTC) energized by a battery
• Option to install an SD card
• Analog inputs, and digital inputs and outputs
The module is energized from the backplane.

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
– 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
• EMC requirement – The cables that connect to
HMI, Ethernet network, RS-485 terminals, and
analog inputs must be screened.
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 application manager
For images, see the appendix.
The module is installed on a backplane, immediately
to the right of the backplane supply module.
1. Install the RTC battery.
The delivery includes the RTC battery.
a) Open the battery hatch.
b) Put the battery in the battery holder.
If the battery is already installed on delivery,
remove the protective film that separates the
battery from the battery holder.
c) Close the battery hatch.
2. If applicable, install an SD card.
3. Remove the dust plugs from slot 1 and 2 of the
backplane.
4. Install the module on the backplane.
The spring lock engages with a click.
