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.
NOVUS AUTOMATION 1/9
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.

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

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
“

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.

• 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

KEY AND DIGITAL INPUT (I/O6) FUNCTIONS
Both the key and the I/O6 digital input can be programmed to execute
functions 7, 8, 9 and 10 shown in Table 2. The key function is
configured in parameter “
”. The digital input function is
configured in parameter IO6.
The digital input can also be configured for function 6: Auto/Manual
mode change.
Programmable FUNCTION Key: Can be assigned to the
-
special functions described for the

When the controller is turned on, its firmware version i s display ed for
3 seconds, after which the controller starts normal operation. The
values of PV and SV are displayed and the outputs are enabled.
Before the controller is ready to be used in a given process, it
requires some basic configuration, such as:
• Input type (T/C, Pt100, 4-20 mA,...) at the “
” prompt,
according to Table 1;
• Output type at “I/O 1”, “I/O 2”,... “I/O 6” prompts (see Table 2);
• Setpoint variable SV. Set the remaining parameters.
• PID parameters (or hysteresis for ON/OFF control)
Other functions, including alarms, ramp and s oak, timer, digital input,
etc., may be useful for a better system performanc e. The parameters
are grouped in 7 cycles.

RAMP AND SOAK PROFILE PROGRAM
Seven ramp and soak profiles with up to 7 segments each can be
programmed. Longer profiles of up to 49 segments can be created by
linking 2 or more profiles.
Figure 11 - Example of a complete ramp
and soak profile
To execute a profile with fewer segments just program 0 (zero) for the
time intervals that follow the last segment to be executed.
The program tolerance “
between PV and SV for the execution of the profile. If this devi ati on is
exceeded, the program will be interrupted until the deviation falls to
within the tolerance band.
Programming 0 (zero) at this prompt disables the tolerance and the
profile execution will not t o be halted even if PV does not follow SV
(time priority as opposed to SV priority).
The ramp and soak event function is used to acti vate alarms at any
segment of program 1. This applies only to program 1.
LINK OF PROGRAMS
It is possible to create a more complex program, with up to 49
segments, joining the seven programs. This way, at the end of a
program execution the controller immediately starts to run another one.
When a program is created, it must be defined in the “LP" screen
whether there will be or not another program.
To make the controller run a given program or many programs
continuously, it is only necessary to l ink a program to i tself or the last
program to the first.
Figure 12 - Example of a pr of ile
with fewer segments. ( T4 i s set 0)
” defines the maximum deviation
To configure and execute a ramp and soak program:
• Program the tolerance value, SV, time and event.
• If any event alarm is required program the ramp and soak event
function.
• Set the control mode to automatic.
• Select ramp and soak program to be executed at prompt
• Start control at the
prompt by selecting YES.
(0 to 7)
Before executing the program the controller waits for PV to reach the
first set point SP0 if
is different than zero.
Should any power failure occur the controller resumes at the
beginning of the segment it currently is.
AUTO TUNE
During auto tune the process is controlled in ON/OFF mode at the
programmed SetPoint (SV). Depending on the process
characteristics large oscil lations above and bel ow 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
• Select auto mode operation at the
• Disable the ramp and soak function (select NO) and program a new
SV value other than the present PV (close to the desired set point).
• Enable auto tuning at the
• Enable the control output at the
During the auto tune procedure the soft-start function will not operate
and large oscillati ons will be induc ed around the setpoint. Make sure
the process can accept these oscillations and fast control output
changes.
If auto tuning results are not satisfactory refer to T able 6 for manual
fine tuning procedure.

INPUT CALIBRATION
All inputs are fac tory c al ibrated and recal i bration s houl d only be done
by qualified personnel. If you are not fami liar with these procedures
do not attempt to calibrate this instrument. The calibration steps are:
a) Select the input type to be calibrated.
b) Set the desired upper and lower display limits.
c) At the input terminals inject an electric al signal corresponding to
a known indication value a little higher than the lower display
limit.
d) Select the
PV so that it matches the injected signal.
e) Inject a signal that corresponds to a v alue a little lower than the
upper limit of the display.
f) Select the
PV so that it matches the injected signal.
g) Repeat steps c) to f) to improve calibration.

PROBLEMS WITH THE CONTROLLER
Connection errors or improper configuration will result in malfuncti oning
of the controller. Carefully revise all cable connections and programming
parameters before operating the unit.
Some error messages will help the user identify possible problems.
Pt100 cable resistance is too high or the sensor is badly
connected.
Different messages other than the ones above should be reported to
the manufacturer. Please inform the serial number if this should
occur. The serial number can be viewed at the display by pressing
key for about 3 seconds.
