UNIVERSAL PROCESS CONTROLLER – INSTRUCTIONS MANUAL V2.1x

PRESENTATION

The N1100 is a process controller incorporating a PID algorithm and
universal inputs (sensor and standard signals) and outputs (logical,
relay and analog outputs). It holds in one single instrument all de main
features that are needed for the vast majority of industrial processes.

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 or WARNING:

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.

OVER-TEMPERATURE PROTECTION

When designing any control system it is essential to consider what
will happen if any part of the system should fail. In temperature
control applications the primary danger is one in which the heating
remains constantly on. In any application where physical injury or
destruction of equipment might occur, it is recommend to install an
independent protection equipment, with a separate temperature
sensor, to disable the heating circuit in case of overheating. Please
note that the alarm relays within the controller will not give protection
under all failure conditions.

INSTALLATION

Insert the unit into the panel cut-out and slide the mounting clamp
from the rear to a firm grip at the panel.

ELECTRICAL CONNECTIONS

All electrical connections are made to the screw terminals at the rear
of the controller. They accept wire sizes from 0.5 to 1.5 mm2 (16 to
22 AWG). The terminals should be tightened to a torque of 0.4 Nm
(3.5 lb in).

To minimize the pick-up of electrical noise, the low voltage DC
connections and the sensor input wiring should be routed away from
high-current power conductors. If this is impractical, use shielded
cables. In general, keep cable lengths to a minimum.

• Digital Input

I/O3 and I/O4 can be used as digital inputs, accepting either dry
contact or NPN open collector signals. Figure 7a shows a switch
driving the I/O3 digital input. I/O4 can be used analogously. The
digital input at I/O5 is driven only by dry contact signals. Figure 7b
shows a typical digital input wiring for I/O5.

When the controller is turned on, its firmware version is displayed for
3 seconds, after which the controller starts normal operation. The
values of PV and SV are displayed and the outputs are enabled.

Before the controller is ready to be used in a given process, it
requires some basic configuration, such as:

• input type (T/C, Pt100, 4-20 mA,...) at the “tYPE

tYPE” prompt,

tYPEtYPE

according to Table 1.

• output type at “I/O 1”, “I/O 2”,... “I/O 5” prompts (see Table 2).

• setpoint variable SV. Set the remaining parameters.

• PID parameters (or hysteresis for ON / OFF control).

Other functions, including alarms, ramp and soak, timer, digital input,
etc., may be useful for a better system performance. The parameters
are grouped in 7 cycles.

CYCLE ACCESS

• Digital Output

I/O3, I/O4 and I/O5 can also be configured as digital outputs (I/O3 and
I/O4 provide a 5 Vdc output signal whereas I/O5 a 12 Vdc signal). An
example of usage is shown in Figure 8 for the I/O3 and in Figure 9 for
the I/O5. I/O5 is electrically isolated from the sensor input.

Table 2 - I/O channel functions

OUTPUTS, ALARMS AND DIGITAL INPUTS CONFIGURATION

The controller input/output channels can assume multiple functions,
depending on configuration: control output, alarm output, digital
output, digital input, and PV or SV analog retransmission. These
channels are identified as I/O1, I/O2, I/O3, I/O4 and I/O 5.

The basic controller model comes loaded with:

• I/O1 - relay output

• I/O2 - relay output

• I/O5 - analog output (0-20 or 4-20mA), pulse 10V max, digital I/O

The options available are:

• I/O3 - 3rd relay (option 1)

• I/O3 and I/O4 - 2 digital input/output (option 2)

• Heater break protection (option 3).

The function code of each I/O can be selected among the options on
Table 2. Only valid function codes are displayed for each I/O (for
example, I/O1, which is a relay, can be configured with functions 0 to
5 only; on the other hand, I/05 can perform all 16 functions).

The description for the functions follows:

• CODE 0 - No function. The I/O channel programmed with code 0

will not be used by the controller. It is available to be used by serial
communication as digital output.

• CODES 1 to 4 - Alarm output - Available for all I/O channels. The

selected channel can be used as output to Alarms 1 to 4.

• CODE 5 - PWM control output - Available for all I/O channels.

• CODE 9 - Digital input - Standard for I/O5 and optional for I/O3 and

I/O4.

Opened: enables R&S program
Closed: holds R&S program (the program resumes when the
contact is opened again)

• CODE 10 - Digital input - Standard for I/O5 and optional for I/O3 and

I/O4. Selects R&S program 1. Used to alternate between the main
Setpoint and a second Setpoint defined by the R&S program 1.

Closed : selects program 1
Opened: uses main Setpoint

• CODE 11 - Analog control output - I/O5 only. 0-20 mA control

output.

• CODE 12 - Analog control output - I/O5 only. 4-20 mA control

output.

• CODES 13 to 16 - Analog retransmission. I/O5 only. Configures

I/O5 to output a 0-20 mA or 4-20 mA analog signal proportional to
PV or SP.

ALARM FUNCTIONS

The controller has 4 independent alarms. They can be programmed
to operate with nine different functions, represented in Table 3.

• Open sensor

It is activated whenever the input sensor is broken or disconnected.

• Event alarm

It activates alarm(s) in specific segments of the program.

• CODE 6 - Digital input - Standard for I/O5 and optional for I/O3 and

I/O4.

Closed : Manual control
Opened: Automatic control

NOVUS AUTOMATION 3/8

• Resistance fail

Detects a heater broken condition, by monitoring the load current
when the control output is activated. This alarm function requires an
optional device (option 3). Details of the "resistance fail" option can
be found in a specific documentation that is sent with the product
when the option is purchased.
