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 / CONECTIONS
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.
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 can not assure total protection.

Table 01 Input types
The input type should be the first parameter to be configured on the
controller. Any modifications on the input type will automatically change
other related parameters. The user must verify the configuration every time
that an input type modification occurs.
OUTPUTS The controller has two outputs. The user can configure these outputs
to operate as Control Output ((trl) or Alarm Output (al).
OUT1 – Output Voltage pulse, 5 Vdc / 25 mA or Output Relay SPST-NO
OUT2 – Output Relay SPST-NO
CONTROL OUTPUT ((TRL) The control strategy can be ON/OFF (when PB = 0.0) or
PID. The PID parameters can be automatically determined enabling the
autotuning function (ATvN).
ALARM OUTPUT (al) The controller contains 2 alarms that can be directed
(assigned) to any output channel. The alarm functions are described in Table
02.
off Output is not used as alarm.
Alarm of Absolute Minimum Value. Triggers when the lo value of measured PV is below the value defined for alarm Setpoint (SPAL).
PV SPAL
Alarm of Absolute Maximum
Value. Triggers when the PV
ki value of measured PV is
above the value defined for
SPAL
alarm Setpoint.
Alarm of Differential. In this function the parameters, SPAL represent the deviation of PV in relation to the SP of CONTROL.

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
Important note: Alarms configured with the ki, dif, and difk functions also trigger their associated output when a sensor fault is identified and signaled by the controller. A relay output, for example, configured to act as a High Alarm (ki), will operate when the SPAL value is exceeded and also when the sensor connected to the controller input is broken.
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.
OFFSET
Allows fine adjustments to the PV reading for compensation of sensor error.
OPERATION
The controller’s front panel, with its parts, can be seen in the Fig. 02:

Increment key and – Decrement key: allow altering the values of the
parameters.
Back key: used to retrocede parameters.
OPERATION 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 3 levels of
parameters are
1 Tuning / 2 Input / 3 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 >> type >> PASS >> PV …
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 level, 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 section
Configuration Protection.

rstr Pas.( Prot
Restore. Restores the factory calibration for all inputs and outputs,
disregarding modifications carried out by the user.
Password Change. Allows defining a new access password, always different from
zero.
Protection. Sets up the Level of Protection. See Table 03.
CONFIGURATION PROTECTION
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 03.
PROTECTION LEVEL 1 2 3 4
PROTECTION LEVELS
Only the Calibration level is protected. Calibration and Input levels.
Calibration, Input and Tuning levels. All levels are protected, including SP.
Table 03 Levels of Protection for the Configuration
ACESS 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 levels.
The prompt PASS precedes the parameters on the protected levels. If no
password is entered, the parameters of the protected levels can only be
visualized.
The Access Password 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 ACCESS PASSWORD
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.
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.
Controller serial number is displayed by pressing for 3 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 autotuning 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.
3/5
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 04 for
guidelines on how to correct the behavior of the process.
