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 the manual thoroughly
before installing and operating
the equipment.
CAUTION OR DANGER:
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
equipment may be impaired.
INSTALLATION / CONNECTIONS
The controller must be fastened on a panel, following the sequence
of steps described below:
•Prepare a panel cut-out according Specifications;
•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.
ELECTRICAL CONNECTIONS
Fig. 01 below shows the electrical terminals of the controller:
Fig. 01 - Connections of the back panel
RECOMMENDATIONS FOR THE INSTALLATION
•All electrical connections are made to the screw terminals at the
rear of the controller.
•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 cannot assure
total protection.

ierr
Alarms of the Sensor Break (Sensor Break Alarm). It
is activated when the Input presents problems such
as interrupted sensor, bad connection, etc.
Table 02 – Alarm functions
Note: Alarm functions on Table 02 are also valid for Alarm 2 (SPA2).
INITIAL BLOCKING OF ALARM
The initial blocking option inhibits the alarm from being recognized
if an alarm condition is present when the controller is first energized
(or after a transition from run YES NO). 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
ierr
.
SAFE OUTPUT VALUE WITH SENSOR FAILURE
This function defines an output value (user defined) to be assigned to
the control output in the event of a sensor failure.
When the input sensor is identified as broken, the controller switches
the control mode to MANUAL while forcing MV to assume the user
configured value in the
1E.ov
parameter. This function requires that
one of the alarms be configured as
1Err
and the
1E.ov
parameter
(control output percentage) programmed with a value other then 0
(zero).
Once this function is triggered, the controller remains in SAFE mode
(MANUAL control output) even after the sensor failure appears to be
fixed. The operator intervention is required for switching back to
AUTO mode.
1E.ov
values are only 0 and 100 % when in ON/OFF control mode.
For PID control mode any value in the range from 0 to 100 % is
accepted.
LBD FUNCTION – LOOP BREAK DETECTION
The parameter defines a time interval, in minutes, within which the
PV is expect to react to a control output signal. If the PV does not
react properly within the time interval configured in
lbd.t
, the
controller interprets this as a control loop break and signals this
occurrence in the display.
A LBD event may be sent to any output channel. Simply configure
the LDB function to the desired output channel (OUT1 or OUT2): the
selected output will be activated when a LDB condition is detected.
When the
Lbd.t
parameter is programmed with 0 (zero), the LDB
function is disabled.
The LBD is useful in detecting system failures, such us defective
sensors or actuators, loads and power supply, among others.
OFFSET
Allows fine adjustments to the PV reading for compensation of
sensor error.
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.

STARTUP
When the controller is powered up, it displays its firmware version for
3 seconds, after which the controller starts normal operation. The
value of PV and SP is then displayed and the outputs are enabled.
In order for the controller to operate properly in a process, its
parameters need to be configured first, such that it can perform
accordingly to the system requirements. The user must be aware of
the importance of each parameter and for each one determine a valid
condition.
The parameters are grouped in levels according to their functionality
and operation easiness. The 5 levels of parameters are:
1 – Operation / 2 – Tuning / 3 – Alarms / 4 – Input / 5 – Calibration
The “P” key is used for accessing the parameters within a level.
Keeping the “P” key pressed, at every 2 seconds the controller jumps
to the next level of parameters, showing the first parameter of each
level:
PV >>
atvn
>>

To enter a particular level, simply release the “P” key when the first
parameter in that level is displayed. To walk through the parameters
in a level, press the “P” key with short strokes. To go back to the
previous parameter in a cycle, press
:
Each parameter is displayed with its prompt in the upper display and
value/condition in the lower display. Depending on the level of
parameter protection adopted, the parameter PASS precedes the
first parameter in the level where the protection becomes active. See

Controller serial number is displayed by pressing
for 5 seconds.
DETERMINATION OF PID PARAMETERS
During the process of determining automatically the PID parameters,
the system is controlled in ON/OFF in the programmed Setpoint. The
auto-tuning process may take several minutes to be completed,
depending on the system. The steps for executing the PID auto-
tuning are:
•Select the process Setpoint.
•Enable auto-tuning at the parameter “
Atvn
”, selecting
FAST
or
FULL
.
The option
FAST
performs the tuning in the minimum possible time,
while the option
FULL
gives priority to accuracy over the speed.
The sign TUNE remains lit during the whole tuning phase. The user
must wait for the tuning to be completed before using the controller.
During auto tuning period the controller will impose oscillations to the
process. PV will oscillate around the programmed set point and
controller output will switch on and off many times.
If the tuning does not result in a satisfactory control, refer to Table 05
for guidelines on how to correct the behavior of the process.

CALIBRATION OF THE INPUT
All 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) Configure the input type to be calibrated in the
type
parameter.
b) Configure the lower and upper limits of indication for the maximum
span of the selected input type.
c) Go to the Calibration Level.
d) Enter the access password.
e) Enable calibration by setting YES in
(alib
parameter.
f) Using an electrical signals simulator, apply a signal a little higher
than the low indication limit for the selected input.
g) Access the parameter “
inLC
”. With the keys and adjust
the display reading such as to match the applied signal. Then
press the key.
h) Apply a signal that corresponds to a value a little lower than the
upper limit of indication.
i) Access the parameter “
inLC
”. With the keys and adjust
the display reading such as to match the applied signal.
j) Return to the Operation Level.
k) Check the resulting accuracy. If not good enough, repeat the
procedure.
Note: When checking the controller calibration with a Pt100
simulator, pay attention to the simulator minimum excitation current
requirement, which may not be compatible with the 0.170 mA
excitation current provided by the controller.
SERIAL COMMUNICATION
The controller can be supplied with an asynchronous RS-485 digital
communication interface for master-slave connection to a host
computer (master).
The controller works as a slave only and all commands are started by
the computer which sends a request to the slave address. The
addressed unit sends back the requested reply.
Broadcast commands (addressed to all indicator units in a multidrop
network) are accepted but no reply is sent back in this case.
