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.
INTRODUCTION
The N1200HC is an extraordinarily versatile process controller. It
accepts in a single model virtually all the sensors and signals used in
the industry and provides the main output types required for the
operation of diverse processes.
The configuration can be performed directly on the controller or through
the USB interface. The
NConfig
software (free) is the configuration
management tool. Connected to the USB of a Windows computer, the
controller is recognized as a serial communications port (COM) running
with a Modbus RTU protocol.
Through the USB interface, even if disconnected from the power
supply, the configuration performed in a piece of equipment can be can
be saved in a file and repeated in other pieces of equipment that
require the same configuration.
It is important that the users read carefully this manual before using the
controller. Verify if the release of this manual matches the instrument
version (the firmware version is shown when the controller is
energized). The N1200HC main characteristics are:
•
Multi-sensor universal input, with no hardware change;
•
Protection for open sensor in any condition;
•
Two separate control outputs: heating and cooling;
•
Self-tuning of PID parameters;
•
Automatic / Manual function with “bumpless” transfer;
•
Three alarm outputs in the basic version, with functions of
minimum, maximum, differential (deviation), open sensor and
event;
•
Timer functions that can be associated to the alarms;
•
Retransmission of PV or SP in 0-20 mA or 4-20 mA;
•
Input for remote setpoint;
•
Digital input with 5 functions;
•
Programmable soft-start;
•
20 setpoint profile programs with 9 segments each, with the ability
to be linked together for a total of 180 segments;
•
Password for parameters protection;
•
Universal power supply.

CONFIGURATION OF OUTPUTS, ALARMS AND DIGITAL INPUTS
The controller input and output channels (I/O) can assume multiple
functions: control output 1 or 2, digital input, digital output, alarm
output, retransmission of PV and SP. These channels are identified
as
I/O 1
,
I/O 2
,
I/O 3
,
I/O 4
and
I/O 5
.
The basic controller model comes loaded with the following features:
I/O 1- output to Relay SPST-NA;
I/O 2- output to Relay SPST-NA;
I/O 5- current output, digital output, digital input;
Optionally, other features can be added, as shown under the item
Identification
in this manual:
-
3R
: I/O3 with output to SPDT relay;
-
DIO
: I/O3 and I/O4 as digital input and output channels;
-
485
: Serial Communication;
The function to be used in each channel of I/O is defined by the user
in accordance with the options shown in the
Table 2
.
