OPERATING MANUAL
1. SAFETY SUMMARY
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
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.
2. INSTALLATION
The controller should be installed in a panel cut out as specified in item 2. First remove the mounting clamp
and insert the controller into the panel cut out. Place the unit into the panel cut-out and slide the mounting
clamps from the rear to a firm grip at the panel.
The internal circuitry can be fully removed from the housing without disconnecting any wiring. Grab firmly the
front panel and pull out the circuitry from the housing.
2.1 ELECTRICAL CONNECTIONS
All 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 AWG). The terminals should be tightened to a torque of 0.4 Nm (3.5 lb in).
The installation must include a power isolating switch or circuit breaker that disconnects all current carrying
conductors. The device should be mounted close to the controller, within easy reach of the operator and
marked as the disconnecting device for the instrument.
Figure 1 shows the electrical terminals of the controller.

connected to terminals 10, 11 and 12, as indicated in figure 1. For full compensation of cable resistance only
cables with equal wire electrical resistance should be used. Table 1 shows the sensor types accepted and
their respective codes.

3.2 POWER
Mains power is connected to terminals 1 and 2. Check the upper side of the housing for proper power
indication.
3.3 CONTROL AND ALARM OUTPUTS
Up to 4 outputs can be configured for control or alarm. The available outputs are identified on the rear panel
as OUTA, OUTB, OUTC or OUTD. Electrical characteristics of each output are:
OUTA: SPST Relay, 1,5 A / 250 Vac (3 A / 30 Vdc); Resistive load; 100 k cycles;
OUTB: Voltage Pulse, 5 Vdc / 20 mA;
OUTC: SPST Relay, 1,5 A / 250 Vac (3 A / 30 Vdc); Resistive load; 100 k cycles;
OUTD: SPDT Relay, 3 A / 250 Vac (3 A / 30 Vdc); Resistive load; 6 k cycles;
or 4-20 mA output. With 80 count resolution, precision: 0,25 mA, maximum load: 500 Ohms.
The output function is defined on controller configuration, parameters IO A, IO B, IO ( and IO d.
Control Output is used to control the process variable using PID algorithm. More than one output can be
selected as control output. When OUTD is configured as Analog Control Output, all other outputs selected
as Control Output will not operate.
Control Outputs are turned off when a sensor error is detected (display “Erro”).
Alarm Outputs are used to signal abnormal PV values, sensor error or end of program. The alarm function
must be selected for each alarm output. (Refer to chapter 9).
4. CONFIGURATION AND OPERATION
Prior to first operation the controller should be fully configured. The user must set basic parameters as
temperature type (“TYPE”), the desired control set point (“ SP “), the alarms set points (“SPA1” and
“SPA2”), etc.
4.1 PARAMETERS FLOW CHART
The programming parameters are organized in 4 different sets or levels
Operation level / Alarms and tuning level / Configuration level / Calibration level
At power up the controller displays a prompt at the Operation Level and remains in this level while under
normal operation.
The other levels are only accessed when a change of parameters is necessary (except for Set Point
change). To reach these other parameters the user must keep the PROG Key (
P ) pressed for about
three seconds. After this time the controller will show the first parameter of the next level. By keeping the
P key pressed for another 3 seconds the next level will be accessed.
Release the P key when the desired level is reached. Press once the P to go to the next prompt in the
same level. When a parameter is shown the display will alternate its name and value. The value can then be
changed by pressing the
or key.
After the last parameter in one level is reached the controller returns to operation level and the display will
indicate the measured temperature.
The display will also go back to the measured temperature whenever the display is inactive for 20 seconds
or more. When a parameter value is changed via keyboard the controller will only accept the new value after
the user presses the
P key to go to next prompt or if the keyboard is left inactive for 20 seconds.
4.2 PROGRAM SECURITY
To avoid tampering, parameter “Prot” and a hardware jumper can be used to disable access to
programming parameters.
With the jumper in the OFF position, all program levels are unprotected. The “Prot” parameter can only be
changed with the jumper in the OFF position.
With the jumper in the ON position or removed, the protection level is defined by the current value of the
“Prot” parameter:
0 No protection. All parameters can be accessed;
1 No access to the calibration level;
2 No access to calibration and configuration levels;
3 No access to calibration, configuration and tuning and alarms levels;
4 No access to calibration, configuration, tuning and alarms and operation (except SP) levels;
5 Fully blocked.

INDICATION
END
SP
TEMPERATURE measured by the sensor. At power up, the upper display shows the
process temperature value. It also shows the messages described in chapter 5 of this
manual. The lower displays shows the set point value which is the temperature value
desired for the process.
rAte TEMPERATURE RATE OF RISE: The user defines the rate of temperature rise from the
starting temperature to the value set in “ SP ”. Rate is defined in °C / minute.
T Sp TIME FOR SOAK: Time in minutes which the temperature will remain at the selected “
SP “. Refer to item 4.
Rvn

RUN: At this prompt the user sets the control output and alarms to active or to inactive.
0 - inactive outputs; 1 - active outputs;
4.4 TUNING AND ALARMS LEVEL
Atvn AUTO-TUNE: Activates the auto-tuning of PID parameters.
0 - Auto-tune is off; 1 - Auto-tune is on;
Pb
Proportional band
PROPORTIONAL BAND: percentage of maximum input span.
When set to zero (0), control action is ON/OFF.
Ir
integral rate
INTEGRAL RATE: Integral time constant in repetitions per minute (Reset). This
constant is not used when controller is set to ON/OFF action (Pb=0).
Dt
derivative time
DERIVATIVE TIME: Derivative time constant in seconds. This constant is not used
when controller is set to ON/OFF action (Pb=0).
(t
Cycle time
CYCLE TIME: Pulse Width Modulation (PWM) period in seconds. This term is not
used when controller is set to ON/OFF action (Pb=0).
