Controller N480D
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
