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.

Controller N2000 USB INTERFACE The USB interface is used for CONFIGURING or MONITORING the controller. The NConfig software must be used for the configuration. It makes it possible to create, view, save and open configurations from the equipment or files in your computer. The tool for saving and opening configurations in files makes it possible to transfer configurations between pieces of equipment and to make backup copies.

Controller N2000 AUTO TUNE During auto tune the process is controlled in ON/OFF mode at the programmed SetPoint (SV). Depending on the process characteristics large oscillations above and below SV may occur and auto tuning may take several minutes to be concluded. The recommended procedure is as follows: • Disable the control output at the rvn prompt by selecting NO. • Select auto mode operation at the Avto prompt by selecting YES.
