Controller N2000S

UNIVERSAL PROCESS CONTROLLER – INSTRUCTIONS MANUAL – V2.1x

SAFETY SUMMARY

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.

INTRODUCTION

N2000S is a controller for servo positioners with two control relays:

one to open and other to close the valve (or damper). Moreover, it

has an analog output that can be programmed to control or retransmit

input or setpoint signals. Its universal input accepts most industry

manufactured sensors and signals.

Configuration can be entirely achieved through the keyboard, no

circuit changes are required. Selection of input and output type,

alarms configuration, and other especial functions are accessed and

programmed through the frontal panel.

It is important that you read the manual thoroughly before using the

controller. Be sure the manual corresponds to your instrument (the

number of the software version can be seen when the controller is

turned on).

CHARACTERISTICS

• Sensor break protection in any condition; Universal multi-sensor

input without hardware change;

• Potentiometer input for current position reading;

• Auto-tuning of PID parameters;

• Control outputs: relays;

• Automatic/Manual “bumpless” transfer;

• Two alarm outputs; functions: minimum, maximum, differential

(deviation), open sensor and event. Two-alarm temporization;

• 4-20 mA or 0-20 mA analog output for Process Variable (PV) or

SetPoint (SP) retransmission;

• 4-function digital input;

• Ramp and soak with 7 programs of 7 segments with linking

capability;

• RS-485 serial communication; RTU MODBUS protocol;

• Configuration protection;

PRESENTATION / OPERATION

The controller frontal panel is shown in Figure 1:

Figure 1 – Frontal panel

PV/Programming Display: Shows the PV value. When in

programming mode, shows the parameter name.

SP/Parameters Display: Shows the SP and other programmable

parameter values of the controller.

COM Indicator: Flashes when data is exchanged with the external

environment.

TUNE Indicator: Lights during automatic tuning.

MAN Indicator: Indicates that the controller is in the manual control

mode.

RUN Indicator: Indicates that the controller is active, with control and

alarm outputs enabled.

OUT Indicator: When the analog output (0-20 mA or 4-20 mA) is set

for controlling actions the indicator lights continuously.

A1, A2 Indicators: Indicates the respective alarm status.

A3 Indicators: Indicates the valve (I/O3) opening output status.

A4 Indicators: Indicates the valve/dumper (I/O4) closing output status.

PROG key: Shows the controller programmable parameters.

BACK Key: ReReturns to the previous parameter shown in the

parameter display.

Increase and

Decrease keys: Change the parameter values.

Auto/Man key: Shortcut for automatic/manual control selection.

Alternates the control mode between automatic and manual each

time the key is pressed.

Programmable Function Key: Can be assigned to the special

functions described for the f.fvnc

f.fvncf.fvnc

f.fvnc parameter.

When the controller is turned on, its firmware version is displayed for

3 seconds, after that the controller starts operating normally. The PV

and SV values are displayed in the upper and lower displays

respectively. Outputs are enabled at this moment as well.

The relay associated to the valve closing is activated during the time

required for the complete valve to close (see parameter “Ser.t

Ser.tSer.t

Ser.t) so

that the controller starts operating with a known reference.

To run smoothly, the controller requires some basic configuration:

• Input type (Thermocouples, Pt100, 4-20 mA, etc.).

• Control setpoint value (SP).

• Control output type (relays, 0-20 mA, pulse).

• PID parameters (or hysteretic for ON / OFF control).
