SAFETY ALERTS
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:
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

PRESENTATION
The N1100 is an extraordinarily versatile process controller. It holds
in one single instrument all the main features needed for the vast
majority of industrial processes. It accepts in a single model virtually
all the sensors and signals used in the industry and provides the
main output types required for the operation of diverse processes.
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.
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).

Table 4 - Temporization Functions for the Alarms
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 option inhibits the alarm from being recognized
if an alarm condition is present when the controller is first energized.
The alarm will be enabled only after the occurrence of a non-alarm
condition followed by a new occurrence for the alarm.
The initial blocking is useful, for instance, when one of the alarms is
configured as a minimum value alarm, causing the activation of the
alarm soon upon the process start-up, an occurrence that may be
undesirable.
The initial blocking is disabled for the sensor break alarm function.
SQUARE ROOT EXTRACTION
When the input type is configured as
SQRT
the controller assumes
the input as a 4-20 mA while extracting the square root of the applied
input signal.
ANALOG RETRANSMISSION OF PV AND SP
The analog output, when not used for control purposes, is available
for retransmitting the PV and SP values in 0-20 or 4-20 mA. This
analog output is electrically isolated from other inputs and outputs.
The analog output signal is scalable, with the output range defined by
the values programmed in the parameters “
SPLL
” and “
SPkL
”.
It is possible to obtain a voltage output by installing a resistor shunt
(550 Ω max.) to the current output terminals (terminals 7 and 8). The
actual resistor value depends on the desired output voltage span.
There is no electrical isolation between serial communication
(RS485) and channel I/O5.
SOFT-START
The soft-start feature avoids abrupt variations in the power delivered
to the load regardless of the system power demand.
This is accomplished by defining a limiting ramp for the control output.
The output is allowed to reach maximum value (100 %) only after the
time programmed in the soft-start parameter has elapsed.
The Soft-start function is generally used in processes that require slow
start-up, where the instantaneous application of 100 % of the available
power to the load may cause damages to parts of the system.
In order to disable this function, the soft-start parameter must be
configured with 0 (zero).
REMOTE SETPOINT
The controller can have its Setpoint value defined by an analog,
remotely generated signal. This feature is enabled through the
channels I/O3, I/O4 or I/O5 when configured as digital inputs and
configured with the function
rsp
(Remote SP selection) or through
the parameter
E.rsp
. The remote Setpoint input accepts the signals
0-20 mA, 4-20 mA, 0-5 V and 0-10 V.
For the signals of 0-20 and 4-20 mA, a shunt resistor of 100
Ω
is
required between terminals, as shown in Figure 4c.
CONTROL MODE
The controller can operate in two different manners: Automatic mode
or Manual mode.
The parameter “
avto
” defines the control mode to be adopted.
In Automatic mode the controller defines the amount of power to be
applied on the process.
In Manual mode the user himself defines this amount of power. The
user can then adjust the MV percentage while displaying PV/MV.
PID AUTOMATIC MODE
For the Automatic mode, there are two different strategies of control:
PID automatic control and ON/OFF automatic control.
PID control has its action based on a control algorithm that takes into
account the deviation of PV with respect to SP, the rate of change of
PV and the steady state error. These parameters are particular to a
system and can be obtained automatically by the controller’s Auto
Tune feature (
Atvn
parameter).
On the other hand, the ON/OFF control (obtained when
Pb
=0)
operates with 0 % or 100 % of power, when PV deviates from SP.
The determination of parameters
Pb
,
Ir
and
Dt
is described in the
item DETERMINATION OF PID PARAMETERS of this manual.

N1100 Controller
NOVUS AUTOMATION 4/11
USB INTERFACE
The USB interface is used for CONFIGURING or MONITORING the
controller. The NConfig software must be used for the configuration.
It makes it possible to create, view, save and open configurations
from the equipment or files in your computer. The tool for saving and
opening configurations in files makes it possible to transfer
configurations between pieces of equipment and to make backup
copies. For specific models, the NConfig software also makes it
possible to update the firmware (internal software) of the controller
through the USB.
For MONITORING purposes you can use any supervisory software
(SCADA) or laboratory software that supports the MODBUS RTU
communication on a serial communications port. When connected to
the USB of a computer, the controller is recognized as a conventional
serial port (COM x). Use the NConfig software or consult the
DEVICE MANAGER in the Windows CONTROL PANEL to identify
the COM port that was assigned to the controller. Consult the
mapping of the MODBUS memory in the controller’s communications
manual and the documentation of your supervisory software to
conduct the MONITORING process.
Follow the procedure below to use the USB communication of the
equipment:
1. Download the NConfig software from our website and install it on
your computer. The USB drivers necessary for operating the
communication will be installed together with the software.
2. Connect the USB cable between the equipment and the
computer. The controller does not have to be connected to a
power supply. The USB will provide enough power to operate the
communication (other equipment functions cannot operate).
3. Open the NConfig software, configure the communication and
start recognition of the device.
The USB interface IS NOT SEPARATE from the
signal input (PV) or the controller’s digital inputs and
outputs. It is intended for temporary use during
CONFIGURATION and MONITORING periods. For
the safety of people and equipment, it must only be
used when the piece of equipment is completely
disconnected from the input/output signals. Using the
USB in any other type of connection is possible but
requires a careful analysis by the person responsible
for installing it. When MONITORING for long periods
of time and with connected inputs and outputs, we
recommend using the RS485 interface, which is
available or optional in most of our products.
INSTALLATION / CONNECTIONS
The controller must be fastened on a panel, following the sequence
of steps described below:
•Prepare a panel cut-out of 45.5 x 45.5 mm;
•Remove the mounting clamps from the controller;
•Insert the controller into the panel cut-out;
•Slide the mounting clamp from the rear to a firm grip at the panel.
RECOMMENDATIONS FOR THE INSTALLATION
•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.
•All electronic instruments must be powered by a clean mains
supply, proper for instrumentation.
•It is strongly recommended to apply RC'S FILTERS (noise
suppressor) to contactor coils, solenoids, etc.
•In any application it is essential to consider what can happen when
any part of the system fails. The controller features by themselves
can not assure total protection.

situation.
P
P 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 powered on, its firmware version is presented
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.
Note: Since many parameters depend on the input type chosen, it
is recommended that the parameter
TYPE
be the first one to be
configured.
The parameters are grouped in levels according to their functionality
and operation easiness. The 7 levels of parameters are:
LEVEL ACCESS
1- Operation
Free access
2- Tuning
Reserved access
3- Programs
4- Alarm
5- Scale
6- I/Os
7- Calibration
Tabele5– Cycles of Parameters
The parameters in the operation level (1st level) are easily accessed
through the
P
key. The access deeper levels use the combination
of Keys:

Press to advance or to retrocede parameters within a level.
At the end of each level, the controller returns to the operation level.
Keep pressing the
P
key to move fast forward in the level.
Alternatively, the controller returns to the operation level after
pressing the key for 3 seconds.
All configuration parameters are stored in protected memory. The
values are saved when the keys or are pressed after changing
a parameter value. The value of SP is saved upon pressing the
key or every 25 seconds.

PROTECTION OF CONFIGURATION
The controller provides means for protecting the parameters
configurations, not allowing modifications to the parameters values,
avoiding tampering or improper manipulation.
The parameter Protection (
PROt
), in the Calibration level,
determines the protection strategy, limiting the access to particular
levels, as shown by the table below.

Table7- Levels of Protection for the Configuration
Access Password
The protected levels, when accessed, request the user to provide the
Access Password for granting permission to change the
configuration of the parameters on these cycles.
The prompt PASS precedes the parameters on the protected levels.
If no password is entered, the parameters of the protected cycles can
only be visualized.
The Access Code is defined by the user in the parameter Password
Change (
PAS.(
), present in the Calibration level
The factory default for the password code is 1111.
Protection of the access code
The protection system built into the controller blocks for 10 minutes
the access to protected parameters after 5 consecutive frustrated
attempts of guessing the correct password.
Master Password
The Master Password is intended for allowing the user to define a
new password in the event of it being forgotten. The Master
Password doesn’t grant access to all parameters, only to the
Password Change parameter (
PAS(
). After defining the new
password, the protected parameters may be accessed (and
modified) using this new password.

N1100 Controller
NOVUS AUTOMATION 9/11
The master password is made up by the last three digits of the serial
number of the controller added to the number 9000.
As an example, for the equipment with serial number 07154321, the
master password is 9 3 2 1.
PROGRAMS OF RAMP AND SOAK
This feature allows the creation of Ramp and Soak Setpoint Profiles
(Programs). Up to 7 different profiles with 7 segments each can be
programmed. Longer profiles of up to 49 segments can be created by
linking 2 or more profiles together.
The figure below displays a profile model:
Figure 8 - Example of a Ramp and Soak program
Once a profile is defined and selected for execution, the controller
starts to generate the SP profile automatically in accordance with the
elaborated program.
To execute a profile with fewer segments just program 0 (zero) for
the time intervals that follow the last segment to be executed.
SV
Time
T1
T2
T3

Figure 9 - Program example with few segments
The program tolerance “
ptol
” defines the maximum deviation
between PV and SP for the execution of the profile. If this deviation is
exceeded, the program will be halted until the deviation falls to within
the tolerance band.
Programming 0 (zero) in the “
Ptol
” parameter disables the program
tolerance and the profile execution will continue regardless of the PV
value (time priority as opposed to SP priority).
LINK OF PROGRAMS
It is possible to create a more complex program (up to 49 segments),
joining two or more programs. This way, at the end of a program
execution the controller immediately starts to run the next one, as
indicated in the parameter “
LP
".
To force the controller to 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.

EVENT
The Event Alarm function associates the alarms to specific segments
of a program. The information of which alarms are to be activated or
deactivated is given in parameters “
PE1
“ to “
PE7
. Press the and
keys until the desired alarm numbers are displayed.
The Event Alarm requires that the Alarm function be configured as
“
rS
“.
Notes:
1. If
PtoL
is different than zero, the controller will wait for the PV to
reach the first program set point SP0 in order to start the
program execution. Otherwise, it will start promptly.
2. Should any power failure occur, the controller resumes the
program execution at the beginning of the segment where it was
interrupted.
DETERMINATION OF PID PARAMETERS
During the automatic tuning the process is controlled in ON / OFF
mode in the programmed SP. Depending on the process behavior,
oscillations may occur above or below the Setpoint. The automatic
tuning may take many minutes to the concluded, particularly in slow
processes.
When the parameter ATUN is altered to YES, the automatic tuning
is immediately initiated by the controller (provided RUN=YES,
otherwise it will wait until this condition becomes true).
Some recommendations for the automatic tuning process are:
•
avto
= YES: make sure the controller is set for automatic control
mode.
•Disable Ramp & Soak programs configuring
Pr n
= 0. (the
automatic tuning algorithm expects a stable Setpoint value)
•Select a Setpoint that is close or equal to the desired process
Setpoint.
•Enable the automatic tuning (
atvn
= YES).
•Enable outputs if not yet enabled (
rvn
= YES).
The “TUNE” indicator on the display stays lit until the completion of
the automatic tuning process.
For control output types relay or pulse, the automatic tuning
calculates the longest suitable period (cycle time (t) for the PWM
output. The cycle time period may be reduced if the process
experiences some oscillation. When driving a SSR, it’s
recommended to set (t = 1 s.
If the automatic tuning does not result in a satisfactory control, refer
to Table 7 for guidelines on how to correct the behavior of the
process.
