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 (TC Pt100 4-20 mA ...) at the “tYPE

tYPE” prompt
according to Table 1;
•output type (relay 0-20 mA 4-20 mA or pulse) at “I/O 1” “I/O

•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.

5.2 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. This
channels are identified as I/O1, I/O2, I/O3, I/O4 and I/O 5.
I/O features on standard model are the following:
I/O 1- Relay output SPST-NA;
I/O 2- Relay output SPST-NA;
I/O 5- current output digital output digital input;
Controller accepts an optional I/O board that may be ordered with the
following functions. See product I entification topic for the
appropriate identification codes:
- 3R: I/O3 with relay output SPDT;
- DIO: I/O3 and I/O4 as input channels and digital output;
I/O functions are user defined according to options presented on
Table 2. Only valid options for the I/O channel being configured will
be available for selection.
I/O channels will start operation 3 seconds after controller power up.
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 1 - Available for all I/O channels.

5.3 ALARM CONFIGURATION
The controller has 4 alarms. Only alarms 1 and 2 have front panel
lamps associated to them.
The alarms can the configured to operate in any of the nine functions
listed on Table 3.
5.4 ALARM TIMER FUNCTIONS
Alarms 1 and 2 can be programmed to have timer functions. The 3
modes of operation are:
- pulse - delayed actuation - oscillator
The desired function can be achieved programming the parameters

The LEDs associated to the alarms will light when the alarm
condition is recognized not following the actual state of the output
which may be temporarily OFF because of the temporization.

5.5 ALARM INITIAL BLOCKING
The initial blocking option inhibits the alarm from being recognized if
an alarm condition is present when the controller is first energized.
The alarm will actuate only after the occurrence of a non alarm
condition followed by a new occurrence for the alarm.
The initial blocking is disabled for the sensor break alarm function.
5.6 ANALOG RETRANSMISSION OF PV AND SP
The analog output when not used for control purposes is available
for retransmitting the SV and SP values in 0-20 or 4-20 mA. This
analog output is electrically isolated from other inputs and outputs.
The analog output signal is scaleable with the output range determined
by the values programmed in the parameters “SPLL
SPLLSPLL
SPLL” and “SPkL
SPkLSPkL
SPkL”.
To obtain a voltage output connect a resistor shunt to the current
output terminals (terminal 7 and 8).

N1100HC Controller
NOVUS AUTOMATION 4/7
5.7 SOFT-START
Defines the time interval for the output to reach its maximum value
(100 %). The soft-start value is programmed in the “SfSt
SfStSfSt
SfSt”
parameter.
The Soft-start is important to processes which require a slow rate of
increase in the applied power preventing the application of 100% of
the power at start-up.
The control output is primarily determined by the PID loop control;
the Soft-start simply limits this output. See also parameters “o1ll
o1llo1ll
o1ll”
and “o1kl
o1klo1kl
o1kl”.
5.8 SQUARE ROOT EXTRACTION
Available when input type 19 is selected. The indicator displays the
square root of the current signal input applied to terminals 10 and 11.

from the rear to a firm grip at the panel.

The N1100HC incorporates a second control output with proportional
action. This second control output is intended primarily for
refrigeration since the control #1 is normally used for heating.

9RAMP AND SOAK PROFILE PROGRAM
Seven ramp and soak profiles with up to 7 segments each can be

linking 2 or more profiles.

The program tolerance “ Ptol

Ptol” defines the maximum deviation
between PV and SV for the execution of the profile. If this deviation is
exceeded the program will be interrupted until the deviation falls to
within the tolerance band.
Programming 0 (zero) at this prompt disables the tolerance and the
profile execution will not to be halted even if PV does not follow SV
(time priority as opposed to SV priority).

Table 5 - Event codes for ramp and soak
To configure and execute a ramp and soak program:
• Program the tolerance value SV time and event.
• If any event alarm is required program the ramp and soak event
function.
• Set the control mode to automatic.
• Select ramp and soak program to be executed at prompt Prn

• Start control at the run prompt rvn

10 AUTO TUNE
During auto tune the process is controlled in ON/OFF mode at the
programmed SetPoint (SV). Depending on the process
characteristics large oscillations above and below SV may occur and
auto tuning may take several minutes to be concluded.
The recommended procedure is as follows:
• Disable the control output at the rvn
rvnrvn
rvn prompt by selecting NO .
• Select auto mode operation at the Avto
AvtoAvto
Avto
prompt by selecting
YES .
• Disable the ramp and soak function (select NO) and program a
new SV value other than the present PV (close to the desired set
point).
• Enable auto tuning at the Atvn
AtvnAtvn
Atvn
prompt by selecting
YES.
• Enable the control output at the rvn
rvnrvn
rvn prompt by selecting YES .
During the auto tune procedure the soft-start function will not operate
and large oscillations will be induced around the setpoint. Make sure
the process can accept these oscillations and fast control output
changes.
If auto tuning results are not satisfactory refer to Table 6 for manual
fine tuning procedure.
