NOVUS Controller N120 - Manual (Page 2)

NOVUS AUTOMATION 2/14
The parameters in the operation level have easy access through the
key
P
. The access deeper levels use the combination of keys:
P and B pressed simultaneously
Press P to advance or B to retrocede parameters within a level. At
the end of each level, the controller returns to the operation level.
Keep pressing the P key to move fast forward in the level.
Alternatively, the controller returns to the operation level after
pressing the B key for 3 seconds.
All configuration parameters are stored in protected memory. The
values are saved when the Keys P or B are pressed after changing a
parameter value. The value of SP is saved upon pressing the P key
or every 25 seconds.

OUTPUTS
Up to 3 outputs can be configured for control (1 or 2) or alarm. The
available outputs are identified on the rear panel as OvT1, OvT2 e
OvT3. Electrical characteristics of each output are:
OUT1: Voltage Pulse, 5 Vdc / 25 mA;
OUT2 output to Relay SPST-NA;
OUT3 output to Relay SPST-NA;
The option to be used on each output is user-defined according to the
options shown in Table 3 e Table 4.
Outputs Functions Code

Alarm 1 output A1
Alarm 2 output A2
Alarm 3 output A3
Alarm 4 output A4
Loop break detection output Lbd
Control 1 output (TR1
Control 2 output (TR2
Table 3 – Outputs Functions
• In the channel configuration are shown on the display, only the
valid options for each channel. These functions are described
below:
• off - No function.
The I/O channel programmed with code 0 will not be used by the
controller.
• Note: Even though functionless, this channel can be activated by
commands via serial communication (MODBUS command 5).
• a1, a2, a3, a4 - - Alarm output.
Available for all I/O channels. The selected channel can be used as
output to Alarms 1 to 4.
• Lbd – Loop Break Detector function.
Assigns the output of the Loop Break Detector alarm to an I/O
channel. Available to all I/O channels.
•
(tr1 - Control output 1.
• (tr2 - Control output 2.
DIGITAL INPUT
Defines the operation adopted by the available digital input terminals
7 and 8 of the controller. The D.in1 parameter defines the desired
function. There are 5 options possible.
Digital Input Functions Code
No function OFF
Automatic/Man mode change
mAN
Run/Stop mode change RVN
Freezes program execution K.PRG
Program 1 selection PR 1
• Table 4 – Functions for the digital input channels
• These functions are described below:
• mAn - Digital Input with Auto/Manual function
Closed: Manual control
Opened: Automatic control
• rvn - Digital Input with RUN function
Closed: = outputs enabled
Opened = outputs disabled
• kprg - Digital Input with Hold Program function
Closed: = Enables execution of the program
Opened: = Interrupts (freezes) execution of the program
• Note: Even when the execution of the program is interrupted, the
control output remains active and controlling the process at the
point (Setpoint) of interruption. The program will resume its
normal execution starting from this same point when the digital
input is closed.
• Pr 1 - Digital Input with function to Execute Program 1
Defines the IO channel as Digital Input with the function of
commanding the execution of the setpoing profile program 1.
Closed: = Selects program 1
Opened: = Uses main Setpoint
Even with ED in OFF the LogChart can start Logging.
ALARMS FUNCTIONS
The controller has 4 independent alarms. They can be programmed
to operate with eight different functions, represented in Table 5.
• off – Alarms turned off.
• ierr – Sensor break alarm.
It is activated whenever the input sensor is broken or disconnected.
• rs – Ramp & soak program event alarm
This alarm is activated by the Ramp & Soak program (refer to the
programs of ramp and soak section on how to set the event alarm).
