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
ll 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
The N3000 is a process controller incorporating a PID algorithm and
universal inputs (sensor and standard signals) 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.
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 circuit in case of overheating. Please
note that the alarm relays within the controller will not give protection
under all failure conditions.

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 m ), pulse 10 V max, digital I/O;
•I/O6 – Digital Input;
The function code of each I/O can be selected 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 configured with functions 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 - larm output - vailable for all I/O channels
(except I/O6). The selected channel can be used as output to
larms 1 to 4.
• CODE 6 - Digital input - Standard for I/O5 and I/O6.
Closed: Manual control
Opened: utomatic control

REMOTE SETPOINT
The remote Setpoint (SP) is enabled by an external digital signal in
either I/O5 or I/O6, when programmed with the code 8 (Select remote
SP input).
n 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 specific 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 activated. This alarm function requires an
optional device (option 3). Details of the "resistance fail" option can
be found in a specific documentation that is sent with the product
when the option is purchased.

ALARM INITIAL BLOCKING
The initial blocking option inhibits the alarm from being recognized if
an alarm condition is present when the controller 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
vailable when input type 19 is selected. 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 m . This
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 “SPLL
SPLLSPLL
SPLL” and
“SPkL
SPkLSPkL
SPkL”. To obtain a voltage output, connect a resistor shunt to the
current output terminals (terminal 1 and 2).
SOFT START
Defines the time interval for the output to reach its maximum value
(100 %). The soft start value is programmed in “SfSt
SfStSfSt
SfSt”. See also
parameters “ovLL
ovLLovLL
ovLL” and “ovkL
ovkLovkL
ovkL”.
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.
ll electrical connections are made to the screw terminals at the rear
of the controller. They accept wire sizes from 0.5 to 1.5 mm2 (16 to
22 WG). 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 should 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 should be laid out away from power lines and
preferably inside grounded conduits.
•Instrument mains (line) supply should be suitable for this purpose
and should not be shared.
•In controlling and monitoring applications, possible consequences
of any system failure must be considered in advance. 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 digital signal in
either I/O5 or I/O6, when programmed with the code 8 (Select remote
SP input). n external resistor shunt of 100  is required between the
terminals 7 and 8.

DIGITAL INPUT
I/O5 and I/O6 can be used as digital inputs, accepting either dry contact
or NPN open collector signals. Figure 7 shows a switch driving the I/O6
digital input. The digital input at I/O5 is driven only by dry contact
signals. Figure 8 shows a typical digital input wiring for I/O5.
Figure 7 – Digital input at I/O6 Figure 8 – Digital input at I/O5
DIGITAL OUTPUT
I/O5 can also be configured as digital output. n example of usage is
shown in Figure 9. I/O5 is electrically isolated from the sensor input.
Figure 9 – I/O5 digital output wiring.
KE 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 “fFvn
fFvnfFvn

When the controller is turned on, its firmware version is displayed 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 m ,...) at the “tYPE
tYPEtYPE
tYPE” 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 soak, timer, digital input,
etc., may be useful for a better system performance. 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
Figure 12 - Example of a profile
with fewer segments. (T4 is set 0)
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 “Ptol
PtolPtol
Ptol” defines the maximum deviation
between PV and SV for the execution of the profile. If this deviation 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 to 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 activate 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
LPLP
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 link a program to itself or the last
program to the first.

Table 5 - Event codes for ramp and soak
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 Prn
PrnPrn
Prn (0 to 7)
• Start control at the rvn
rvnrvn
rvn prompt by selecting YES.
Before executing the program the controller waits for PV to reach the
first set point SP0 if PtoL
PtoLPtoL
PtoL 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 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
rvnrvn
rvn prompt by selecting NO.
• Select auto mode operation at the Avto
AvtoAvto
Avto prompt by selecting YES.
• 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 Atvn
AtvnAtvn
Atvn prompt by selecting YES.
• Enable the control output at the rvn
rvnrvn
rvn prompt by selecting YES.
During the auto tune procedure the soft-start function will not operate
and large oscillations will be induced 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 Table 6 for manual
fine tuning procedure.

CALIBRATION
INPUT CALIBRATION
ll inputs are factory calibrated and recalibration should only be done
by qualified personnel. If you are not familiar 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) t the input terminals inject an electrical signal corresponding to
a known indication value a little higher than the lower display
limit.
d) Select the inL(
