UNIVERSAL PROCESS CONTROLLER – INSTRUCTIONS MANUAL – V3.0x E
SAFETY ALERTS
The symbols below are used on the equipment and throughout this
document to draw the user's attention to important operational and
safety information.
CAUTION or WARNING:
Read complete instructions prior to
installation and operation of the unit.
All safety related instructions that appear in the manual must be
observed to ensure personal safety and to prevent damage to either
the instrument or the system. If the instrument is used in a manner
not specified by the manufacturer, the protection provided by the
equipment may be impaired.
PRESENTATION
The N2000 is an extraordinarily versatile process controller. It holds
in one single instrument all the main features needed for the vast
majority of industrial processes. It accepts in a single model virtually
all the sensors and signals used in the industry and provides the
main output types required for the operation of diverse processes.
The configuration can be performed directly on the controller or through
the USB interface. The NConfig software (free) is the configuration
management tool. Connected to the USB of a Windows computer, the
controller is recognized as a serial communications port (COM) running
with a Modbus RTU protocol.
Through the USB interface, even if disconnected from the power
supply, the configuration performed in a piece of equipment can be can
be saved in a file and repeated in other pieces of equipment that
require the same configuration.
It is important that the users read carefully this manual before using the
controller. Verify if the release of this manual matches the instrument
version (the firmware version is shown when the controller is
energized).
• Multi-sensor universal input (sensors and standard signals);
• Relay, 4-20 mA and logic pulse control outputs all available in the
standard model;
• Self-tuning of PID parameters;
• Automatic / Manual function with "bumpless" transfer;
• Four modes of independents alarms, with functions of minimum,
maximum, differential (deviation), open sensor and event;
• Timer functions that can be associated to the alarms;
• Retransmission of PV or SP in 0-20 mA or 4-20 mA;
• Input for remote setpoint;
• Digital input with 5 functions;
• Programmable soft-start;
• 7 setpoint profile programs with 7 segments each, with the ability
to be linked together for a total of 49 segments;
• RS-485 Serial communication, MODBUS RTU protocol;
• Password for parameters protection;
• Universal power supply.

OUTPUTS, ALARMS AND DIGITAL INPUTS CONFIGURATION
The controller input/output channels can assume multiple functions,
depending on configuration: control output, alarm output, digital
output, digital input, and PV or SV analog retransmission. These
channels are identified as I/O1, I/O2, I/O3, I/O4, I/O 5 and I/O6.
The basic controller model comes loaded with:
I/O1 and I/O2 - SPDT relay output;
I/O3 and I/O4 - SPST relay output;
I/O5 - analog output (0-20 or 4-20 mA), pulse 10 V max, digital I/O;
I/O6 - Digital Input.
Note: When a function is selected to operate through digital
input, the controller does not respond to the equivalent function
command given in the frontal keypad.
