INSTRUCTIONS MANUAL

– V2.0x

INTRODUCTION

N120 has all the main features needed for control and alarm functions in

different industrial processes. It accepts in a single model the majority

of the sensors and signals used in the industry and provides the main

output types required for dual action control (Heat and Cool) and

alarm monitoring.

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.

The N120 in addition to being a controller is an electronic datalogger.

The logger function operates independently of the controller. The

parameter setting of the datalogger is made using LogChart-II

software.

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).

CARACTERÍSTICAS PRINCIPAIS

• Capable of storing 32700 registers (datalogger);

• Universal multi-sensor input without hardware change;

• Protection for open sensor in any condition;

• Relay and logic pulse control outputs available in the standard

model;

• Self-tuning of PID parameters;

• Automatic / Manual function with “bumpless” transfer;

• Up to 4 alarm outputs, with functions of minimum, maximum,

differential (deviation), open sensor and event;

• Timer functions that can be associated to the alarms;

• Digital input with 4 functions;

• Programmable soft-start;

• 20 setpoint profile programs with 9 segments each, with the ability

to be linked together for a total of 180 segments;

• Password for parameters protection;

• Função LBD (loop break detector);

• Universal power supply: 100-240 Vac, ±10 %.

OPERATION

The controller front panel is shown in Fig. 1.

Fig. 1 – Front panel elements

Display: Shows the value and status of the controller parameters.

COM indicator: Flashes to indicate communication activity in the

RS485 interface.

TUNE indicator: Stays ON while the controller is in tuning process.

MAN indicator: Signals that the controller is in the manual control

mode.

RUN indicator: Indicates that the controller is active, with the control

output and alarms enabled.

OUT indicator: For relay or pulse control output; it reflects the actual

state of the output. If an analog output is assigned for control, the

OUT indicator lights continuously.

A1, A2, A3 and A4 indicators: signalize the occurrence of alarm

situation.

P Key (Program key): used to walk through the menu

parameters.

Back Key: used to retrocede parameters.

Increment key and

- Decrement key: allow altering the

values of the parameters.

When the controller is turned on, its firmware version is delayed for 3

seconds, after which the controller starts normal operation. The

values of PV and SP are displayed and the outputs are enabled.

In order to operate appropriately, the controller needs a configuration

that is the definition of each one of the several parameters presented by

the controller. The user must be aware of the importance of each

parameter and for each one determine a valid condition or a valid value.

Important:

Always the first parameter to set is the input type.

The parameters are grouped in levels according to their functionality

and operation easiness. The 7 levels of parameters are:

3- R&S Programs

4- Alarms
