AL CONTROLLER – INSTRUCTIONS MANUAL – V4.0x

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 – Controller electrical connections

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

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.

Control output is Always OFF when an error in the input signal is

detected.

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).

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
