TEMPERATURE CONTROL OUTPUT
The process control output can operate in the following modes: 1) ON/OFF Mode
or 2) PID Mode.
To operate in ON/OFF Mode, you must set the PB parameter to 0.0. The values of
the PID parameters can be set automatically with the Auto-tuning function
(ATvN).
ALARM OUTPUT
The controller has an alarm, which can be directed to any output channel and
can operate with one of the functions described in Table 2:

Important note: Alarms configured with functions ki, diff, and diffk will also trigger the related output when the controller identifies and signals a sensor failure. A relay type output configured to act as a Maximum Alarm (ki), for example, will act when the SPAL value is exceeded and when the sensor connected to the controller input is broken.
NOVUS AUTOMATION
N1040T Controller
ALARM INITIAL BLOCK
The Initial Block feature inhibits the alarm from being activated if an alarm
condition exists in the process when the controller goes into operation. The
alarm will only be enabled after the process has passed a non-alarm condition.
This function is useful, for example, at the beginning of the process control
operation. At this point, the PV value is still far from the value set with
SP. Thus, alarm situations are expected and often their signaling is unwanted.
The Initial Block is not valid for the ierr function (Open Sensor).
OFFSET
Feature that allows you to make small adjustments to the PV indication. It
allows you to correct measurement errors that appear, for example, when
replacing a temperature sensor.
LOOP BREAK DETECTION FUNCTION
The lbd.t parameter sets a maximum time interval, in minutes, for PV to react
to the command from the control output. If there is not a minimal and proper
reaction throughout this interval, the controller will signal the occurrence
of a LBD event on its display. This indicates problems in the control loop. If
you set the lbd.t parameter to 0 (zero), this function is disabled. This
function allows you to detect problems in the installation, such as a bad
actuator or a failure in the power supply process to the load.
SAFE OUTPUT FUNCTION DURING SENSOR FAILURE
Function that puts the control output into a safe condition for the process
when identifying an error in the sensor input. When identifying a sensor
failure, the controller will set the percentage value (set in 1E.ov parameter)
for the control output. The controller will remain in this condition until the
sensor failure disappears. When in ON/OFF Mode, the values for 1E.ov are only
0 and 100 %. When in PID Mode, any values between 0 and 100 % are accepted.
USB INTERFACE
The USB interface is used to CONFIGURE, MONITOR, or UPDATE the FIRMWARE. To do
this, you must use QuickTune software, which offers features to create, view,
save, and open configurations from the device or from files on your computer.
The feature to save and open configurations in files allows you to transfer
configurations between devices and create backups. For specific models,
QuickTune allows you to upgrade the firmware (internal software) of the
controller via USB interface. To MONITOR, you can use any supervisory (SCADA)
or laboratory software that supports Modbus RTU communication over a serial
communication port. When connected to the USB interface of a computer, the
controller will be recognized as a conventional serial port (COM x). You
should use QuickTune software or consult the Device Manager in the Windows
Control Panel to identify the COM port assigned to the device. Refer to the
Modbus memory mapping in the device communication manual and the supervisory
software documentation. To use the USB communication, follow the steps below:
1. Download QuickTune software, free of charge, from our website and install
it on the computer to be used. The USB drivers required for the operation of
the communication will be installed with the software.
2. Connect the USB cable between the device and the computer. The controller
does not need to be powered. The USB interface will provide enough power for
the
2/7
communication to operate (other device functions may not operate). 3. Run
QuickTune, configure the communication, and start the device recognition.
The USB interface IS NOT ISOLATED from the signal input (INPUT) and possible
digital inputs and outputs of the controller. Its purpose is temporary use
during CONFIGURATION and MONITORING periods. For the safety of people and
equipment, it should only be used when the equipment is fully disconnected
from the input/output signals. The USB interface can be used in any other
situation, but it requires careful consideration by the people performing the
installation. For MONITORING over long periods and with the inputs and outputs
connected, it is recommended to use the RS485 interface, available or optional
in most of our devices.
TIMERS
The controller has 2 timers, which can operate independently of the
temperature control.
T1 TIMER
T1 is the main timer. It has several features that provide different modes of
operation.
T1 TIMER – STARTUP MODES
T1 Timer has 4 trigger modes:
RUN Allows you to start time counting when activating control (RvN = YES).
SP Allows you to start time counting when the PV value reaches the SP value
set for the process.
F Allows you to start time counting by using the key. Once the timing has
started, pressing the key again will interrupt the process.
To start a new cycle, press the key again.
DI Allows you to start time counting via Digital Input. When you trigger the
DI (close contact), the time counting will start. If the DI is disabled (open
contact) before the end of the timer, it will be interrupted. Returning to DI
will start a new cycle.
Note: If you manually set the RvN parameter to NO (control disabled), the
triggering options via key and DI will not allow you to re-enable control (RvN
= YES).
T1 TIMER – OPERATION MODES
T1 Timer has 3 operation modes:
off T1 output turns off at the end of T1. In this mode, T1 output turns on at
the beginning of T1 and turns off at the end of T1. The A1 flag turns on at
the beginning of the timer and flashes after the end of the T1 interval.
On T1 output turns on at the end of T1. When T1 timer starts, the T1 output
remains off. At the end of the timer, T1 output is turned on and will remain
in this condition until a new cycle starts. The A1 flag flashes during the
timing of T1. After T1, it
NOVUS AUTOMATION
N1040T Controller
turns on permanently, signaling that the output is still on. On.x T1 output
remains on at the end of T1. The T1 output is switched on at the beginning of
T1 timer and remains in this condition even at the end of the timing. The A1
flag turns on during the timing of T1. After T1, it starts flashing, signaling
that the output is still on. The operation modes define the behavior of the
outputs linked to the timer. You can link to any available output: OUT1, OUT2,
OUT3, or OUT4. The A1 flag indicates the current stage of the timer.
T2 TIMER
Secondary timer. It starts its timing at the end of T1. It can also be linked
to any available output on the controller. The linked output always turns on
at the beginning of T2 and turns off at the end. The A2 flag indicates the
condition of timing T2:
T2 in progress A2 on. T2 not started or already finished A2 off.
TIMING DIRECTION
The time counting for the timers can occur in 2 modes: 1) Increasing Mode or
2) Decreasing Mode. In Increasing Mode (UP), counting starts at 0 and goes up
to the programmed time interval (T1, T2) In Decreasing Mode (DOWN), it starts
at the programmed time value and goes down to 0.
BEHAVIOR OF THE TEMPERATURE CONTROL AT THE END OF THE TIMER
During the timing intervals of T1 and T2, the temperature control has normal
operation. The output defined as Temperature Control acts to bring the PV
value to the value set in SP. However, at the end of the T1 + T2 interval, it
is possible to configure the controller to disable temperature control,
setting the RvN parameter to NO. See T.E.(.0 Parameter (Timer Cycle).
TIMER TIME BASE
The TBAS parameter (Timer Cycle) allows you to set the time base to be used.
The options are:
Sec MM:SS. The time intervals T1 and T2 are shown in minutes and seconds.
Min HH:MM. The time intervals T1 and T2 are shown in hours and minutes.

STARTUP
When powered up, the controller displays its software version number for the
first 3 seconds. After that, it will show the measured process variable (PV)
value (temperature) in the upper display and the SP value in the lower
display. This is the Indication Screen. To be used in a process, you need to
configure the controller. To configure it, you must define each of its
parameters. The configuration parameters are gathered into affinity groups,
called parameter cycles:
Operation / Tuning / Timer / Alarms / Input / Calibration The key gives access
to the cycles and their parameters. By holding down the key, the controller
jumps from one cycle to another every 2 seconds, displaying the first
parameter of each cycle: PV >> atvn >> t1 >> fva4 >> type >> pass >> PV … To
enter the desired cycle, simply release the key when its first parameter is
displayed. To advance through the parameters of this cycle, press the key with
short touches. At the end of each cycle, the controller will return to the
Indication Screen. The symbol for each parameter will be shown in the upper
display while its respective value/condition will be shown in the lower
display.

The controller is supplied with the Access Password set to 1111.
PASSWORD PROTECTION
The controller has a safety system. It helps prevent the input of several
passwords in an attempt to get the correct password right. Once 5 consecutive
invalid passwords are identified, the controller will stop accepting passwords
for 10 minutes.
MASTER PASSWORD
If you forget your password, you can use the Master Password feature. When
inserted, this password allows you to change the Password Change parameter
(PAS.() and set a new password for the controller.
The master password is composed of the last three digits of the controller’s
serial number plus the number 9000.
For a device with serial number 07154321, for example, the master password is
9 3 2 1.
You can obtain the serial number of the controller by pressing for 5 seconds.
SETTING THE PID PARAMETERS
During automatic tuning, the process is controlled in ON/OFF mode at the
programmed Setpoint (SP).
In some processes, automatic tuning can take many minutes to complete.
The recommended procedure for running it is:
· Set the desired SP value for the process.
· In the Atvn screen, enable automatic tuning by selecting between FAST or
FULL options.
The FAST option performs the tuning in the shortest possible time. The FULL
option prioritizes more precise tuning.
During automatic tuning, the TUNE flag will remain lit on the front of the
controller. You must wait until the tuning process is finished before you can
use the controller.
During the Auto-tuning, PV oscillations can be induced in the process around
the Setpoint.
If the tuning does not result in satisfactory control, Table 5 gives
guidelines for correcting the process behavior:
