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
unit.
CAUTION OR WARNING:
Electrical S hock 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 i nstrument is used in a manner
not specified by the manufacturer, the protection provided by the
equipment may be impaired.
INTRODUCTION
The N3000 is a proc ess controller incorporating a P ID algorithm and
universal inputs (sensor and standard si gnals) and outputs (logical,
relay and analog outputs). It holds in one single instrument all de
main features that are needed for the vast majority of industrial
processes.
CONFIGURATION
INPUT TYPE SELECTION
Select the input type (in parameter “
Pt100
range: -200 to 530 °C (-328 to 986 ºF)
”) from Table 1 below.
OVER-TEMPERATURE PROTECTION
When designing any control system it is essential to consider what
will happen if any part of the system should fail. In temperature
control applications the primary danger is one in which the heating
remains constantly on. In any application where physical injury or
destruction of equipment might occur, it is recommend to install an
independent protection equipment, with a separate temperature
sensor, to disable the heating c ircuit in case of overheating. Please
note that the alarm relays within the controller wil l not give protection
under all failure conditions.

Table 1 - Input Types
OUTPUTS, ALARMS AND DIGITAL INPUTS CONFIGURATION
The controller input/output c hannels 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;
The function code of each I/O can be selec ted among the options on
Table 2. Only valid function codes are displayed for each I/O (for
example, I/O1, which is a relay , can be confi gured with functi ons 0 to
5 only; on the other hand, I/05 can perform all 16 functions).
The description for the functions follows:
• CODE 0 - No function. The I/O channel programmed with code 0
will not be used by the controller. It is available to be used by serial
communication as digital output.
• CODES 1 to 4 - Alarm output - Available for all I/O channels
(except I/O6). The selected channel can be used as output to
Alarms 1 to 4.
• CODE 6 - Digital input - Standard for I/O5 and I/O6.

• CODES 13 to 16 - Analog retransmission. I/O5 only. Configures
I/O5 to output a 0-20 mA or 4-20 mA analog signal proportional to
PV or SP.
REMOTE SETPOINT
The remote Setpoint (SP) is enabled by an external digi tal signal in
either I/O5 or I/O6, when programmed with the code 8 (Select remote
SP input).
An external resistor shunt of 100 Ω is required between the terminals
7 and 8.
ALARMS FUNCTION
The controller has 4 alarms. The alarms can the configured to
operate in any of the nine functions listed on Table 3.
• Open sensor
It is activated whenever the input sensor is broken or disconnected.
• Event alarm
It activates alarm(s) in specifi c segments of the program. See item
7.2 in this manual.
• Event alarm
Detects a heater broken condition, by monitoring the load current
when the control output is ac tivated. This alarm functi on requires an
optional device (option 3). Details of the "resis tance fail" option can
be found in a specific documentation that is sent with the product
when the option is purchased.

• Minimum value
It is activated when the measured value i s below the v alue defined i n
the alarm Setpoint.
• Maximum value
It is activated when the meas ured val ue is above t he val ue defi ned in
the alarm Setpoint.
• Differential (or Band)
In this function, the parameters “

” represent the PV
deviation as compared to the main SP.
In a positive deviation, the di fferential alarm will be triggered when
the measured value is out of the range defined in:
( SP – Deviation) and (SP + Deviation)
In a negative deviation, the differenti al alarm will be triggered when
the measured value is within the range defined above.
• Minimum differential
It is activated when the measured value is below the value defined in.
(SP - Deviation)
• Maximum differential
It is activated when the measured value is above the value defined in:
(SP + Deviation)
ALARM TIMER FUNCTIONS
Alarms 1 and 2 can be programmed to have timer functions. The 3
modes of operation are:
1- Pulse 2- delayed actuation 3- Oscillator
The desired function can be achieved programming the parameters

The LEDs associated to the alarms will light when the alarm condition
is recognized, not following the actual state of the output, which may
be temporarily OFF because of the temporization.

ALARM INITIAL BLOCKING
The initial blocking opti on inhibits the alarm from being recognized if
an alarm condition is present when the controll er is first energized.
The alarm will actuate only after the occurrence of a non alarm
condition followed by a new occurrence for the alarm.
The initial blocking is disabled for the sensor break alarm function.
SQUARE ROOT EXTRACTION
Available when input type 19 is sel ected. The indicator displays the
square root of the current signal input applied to terminals 22 and 24.
ANALOG RETRANSMISSION OF PV AND SP
The analog output, when not used for control purposes, is available
for retransmitting the SV and SP values in 0-20 or 4-20 mA. Thi s
analog output is electrically isolated from other inputs and outputs.
The analog output signal is scaleable, with the output range
determined by the values programmed in the parameters “
”. To obtain a voltage output, connect a resistor shunt to the
“
” and
current output terminals (terminal 1 and 2).

INSTALLATION / CONNECTION
Insert the unit into the panel cut-out and slide the mounting clamp
from the rear to a firm grip at the panel.
All electrical connecti ons are made to the screw terminals at t he rear
of the controller. They accept wire siz es from 0.5 to 1.5 mm2 (16 to
22 AWG). The terminals should be tightened to a torque of 0.4 Nm
(3.5 lb in).
To minimize the pick-up of electrical noise, the low voltage DC
connections and the sensor input wiring s hould be routed away from
high-current power conductors. If this is impractical, use shielded
cables. In general, keep cable lengths to a minimum.
RECOMMENDATIONS FOR INSTALLATION
• Input signal wires s hould be laid out away from power lines and
preferably inside grounded conduits.
• Instrument mains (line) supply should be suitabl e for this purpose
and should not be shared.
• In controlling and monitoring applicati ons, possible consequences
of any system failure mus t be considered in advanc e. The internal
alarm relay does not warrant total protection.
• Use of RC filters (47 R and 100 nF, serial) are highly
recommended when driving solenoids, contactor coils or other
inductive loads.

• RTD (Pt100)
Figure 4 shows the Pt100 wiring, for 3 conductors. Terminals 10, 11 and 12
must have the same wire resistance for proper cable length compensation.
For 2 wire Pt100, shor t circuit t erminals 10 and 11.
• 4-20 mA:
Refer to Figure 5. (The controller provides an internal electronic
shunt for the input current. No changes in the circuit are necessary).
• Alarm and output connection
When I/O channels are set up as output channels, they must have
their capacity respected, according do specifications.
• Remote setpoint:
The remote Setpoint (SP) is enabled by an external digi tal signal in
either I/O5 or I/O6, when programmed with the code 8 (Select remote
SP input).An external resistor shunt of 100 is required between the
terminals 7 and 8.
