TEMPERATURE CONTROLLER – INSTRUCIONS MANUAL – V1.0x D
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 / CONNECTIONS
The controller must be fastened on a panel, following the sequence
of steps described below:
•
Prepare a panel cut-out of 45 x 93 mm;
•
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.
ELECTRICAL CONNECTIONS

RECOMMENDATIONS FOR THE INSTALLATION
•
Leads of input signals may travel the plant, separately of output
and feeding leads, if is possible in grounded conduits.
•
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.
FEATURES
INPUT TYPE SELECTION
The input type to be used by the controller is defined in the
equipment settings.

Notes:
1-
The specification of controller accuracy does not consider the
error showed by the temperature sensor used.
2-
Suitable extension cables must be used with thermocouples.
3-
In order to use 2-wire Pt100 thread, connect 23 and 24 terminals.
The sensor must be connected between 22 and 23 terminals. If
the sensor is 4-wired, keep one of the wires disconnected close to
the controller. The wires used must always have the same section
(same gauge).
OUTPUTS
The controller offers two, three or four output channels, depending on
the loaded optional features. Those channels are configured by the
user to act as control outputs, alarm outputs, LBD Function or PV or
SP retransmission.

-
Logical pulse, 5 Vdc / 25 mA
Available at terminals 19 and 20 of controller
OUT2
-
Relay SPST-NA
Available at terminals 17 and 18 of controller
OUT3
-
Relay SPST-NA
Available at terminals 15 and 16 of controller
