OPERATING MANUAL
1. SAFETY SUMMARY
The symbols below are used on the equipment and throu hout this document to draw the user’s attention to
important operational and safety information.
CAUTION or WARNIN :
Read complete instructions prior to installation
and operation of the unit.
CAUTION or WARNIN :
Electrical Shock Hazard
All safety related instructions that appear in the manual must be observed to ensure personal safety and to
prevent dama e 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 mountin clamp
and insert the controller into the panel cut out. Place the unit into the panel cut-out and slide the mountin
clamps from the rear to a firm rip at the panel.
The internal circuitry can be fully removed from the housin without disconnectin any wirin . Grab firmly the
front panel and pull out the circuitry from the housin .
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 ti htened to a torque of 0.4 Nm (3.5 lb in).
The installation must include a power isolatin switch or circuit breaker that disconnects all current carryin
conductors. The device should be mounted close to the controller, within easy reach of the operator and
marked as the disconnectin device for the instrument.
Fi ure 1 shows the electrical terminals of the controller.

3.1 TEMPERATURE SENSOR INPUT
Thermocouples are connected to terminals 10 and 11 with positive in terminal 11. Pt100 sensors are
connected to terminals 10, 11 and 12, as indicated in fi ure 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 housin for proper power
indication.
3.3 CONTROL AND ALARM OUTPUTS
Up to 4 outputs can be confi ured 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: Volta e 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 confi uration, parameters IO A

Control Output is used to control the process variable usin PID al orithm. More than one output can be
selected as control output. When OUTD is confi ured 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
ErroErro
Erro”).
Alarm Outputs are used to si nal abnormal PV values, sensor error or end of pro ram. The alarm function
must be selected for each alarm output. (Refer to chapter 9).
4. CONFI URATION AND OPERATION
Prior to first operation the controller should be fully confi ured. The user must set basic parameters as
temperature type (“TYPE
TYPETYPE
TYPE”), the desired control set point (“ SP

“SPA2

4.1 PARAMETERS FLOW CHART
The pro rammin parameters are or anized 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 chan e of parameters is necessary (except for Set Point
chan e). To reach these other parameters the user must keep the PRO Key (
