UNIVERSAL PROCESS CONTROLLER – INSTRUCTIONS MANUAL – V3.0x A
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.
CAUTION or WARNING:
Electrical Shock Hazard
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;
• Comunicação serial RS-485, protocolo MODBUS RTU;
• 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.
