UNIVERSAL CONTROLLER – INSTRUCTIONS MANUAL – V4.0x B

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:

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.

INSTALLATION

The controller must be installed on a panel with a square opening with

the specified dimensions. In order to fasten to the panel, remove the

clamps from the controller, introduce the controller in the panel’s

opening through the front and put the clamps back on the body of the

controller through the rear side of the panel. Firmly press the clamps in

order to fasten the controller to the panel.
The entire internal part of the controller can be removed from its

housing from the front of the panel, without needing to remove the

housing or clamps, or undo the connections. To extract the controller

from its housing, hold it from the front and pull.
Fig. 1 shows the electrical terminals of the controller.

Fig. 1 - Electrical connections of the controller

Thermocouples must be connected between pins 10 and 11. The

extension cable positive must be connected to terminal number 11.
Pt100 type sensors must be connected in 3 wires to terminals 10, 11

and 12. For Pt100 in 2 wires, terminals 11 and 12 must be

interconnected. For adequate compensation of the cable length, the

conductors of this cable must have the same section (gauge).

CONTROL OUTPUTS AND ALARM (OUTA, OUTB, OUTC AND

OUTD)
The controller can have 2, 3 or 4 outputs, which can be configured as

control outputs or alarm outputs. These outputs are identified on the

rear panel of the controller as OUTA, OUTB, OUTC and OUTD.
The output type (control or alarm) is defined in the controller’s

configuration. The output configuration is individual and defined in the
ovt.A

, ovt.B, ovt.(, and ovt.d parameters respectively.

Output control is the output intended to control the process

temperature. It is possible to configure different outputs as the control

output, however, when the OUTD output is configured as the Analog

Output Control, the other control outputs are disabled.
The output control is always off when the “Erro” message is shown

on the controller’s display, signaling a process failure, defect in the

sensor or connection error.
Alarm outputs are used for signaling and/or safety of the process. For

outputs defined as alarm output, it is also necessary to define the alarm

function (see the Alarm Function Description item of this manual).

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 (A1SP and A2SP),

etc.
PARAMETERS FLOW CHART
The programming parameters are organized in 5 different levels

(parameter groups):

- Operation level

- Tuning level

- Program level

- Input level

- Calibration level

When Turned On, the controller displays the first screen of the

Operation Cycle. This screen shows on the red display (top), the

measured temperature value (PV) and also the Set Point value of the
