NOVUS AUTOMATION 5/7

PROGRAMS CYCLE

Ptol

Program Tolerance - Maximum admitted deviation of

PV with respect to SP. If exceeded, the program

execution is suspended (the internal timer freezes) until

the deviation be returns back within the defined

tolerance.

The value 0 (zero) disables the function.

Psp0

Psp9

Program SP’s, 0 to 9: Group of 10 values of SP that

define the Ramp and Soak profile segments.

Pt1

Pt9

Program Time - Time intervals of program

segments. Defines the time of duration, in minutes,

of each 9 program segments. Configurable between 0

and 9999 minutes.

Pe1

Pe9

Program event - Program Segment Alarm.

Parameters that define which alarms are to be

activated during the execution of a certain program

segment:

OFF Do not start the alarm in this segment.

A1 Start alarm 1 when the program reaches

this segment.

A2 Start alarm 2 when the program reaches

this segment.

A1A2 Start alarm 1 and 2 when the program

reaches this segment.

The alarms chosen must have its function configured

as “rS”.

rPt.P

Repeat Program - Determines the number of times

which one program must be REPEATED besides the

first execution. Configurable between 0 and 9999

times. After the last execution, all controller outputs

are turned off ((RUN=OFF).

ALARMS CYCLE

Fva1

Fva2

Function Alarm. Defines the functions for the alarms

among the options of the Table 02.

Sp.a1

Sp.a2

Alarm SP: Value that defines the alarms actuation

point. For alarms programmed with functions of

Differential type, these parameters define deviations.

bla1

bla2

Blocking Alarm.

YES Enables initial blocking.

NO Inhibits initial blocking.

xya1

xya2

Alarm Hysteresis. Defines the difference between the

value of PV at which the alarm is triggered and the

value at which it is turned off (in engineering units).

Flsh

Flash. Allows visual signalization of an alarm

occurrence by flashing the indication of PV in the

operation level.

YES Enables the alarm signalization blinking PV.

NO Disable the alarm signalization blinking PV.

INPUT CYCLE

Type

Input Type. Selects the input signal type to be

connected to the process variable input. Refer to

Table 01.

fltr

Digital Input Filter. Used to improve the stability of

the measured signal (PV). Adjustable between 0 and

20. In 0 (zero) it means filter turned off and 20 means

maximum filter. The higher the filter value, the slower

is the response of the measured value.

Dp.po

Decimal Point. Determines the presentation of the

decimal point.

vni t

Unit. Defines the temperature unit to be used:

( Indication in Celsius.

f Indication in Fahrenheit.

0ffs

Offset. Parameter that allows the user to correct the

PV value indicated.

Spll

SP Low Limit. Defines the SP lower limit. To 0-50

mV input type sets the lower range for SP and PV

indication.

Spxl

SP High Limit. Defines the SP upper limit.

1e.ov

Percentage value to be applied to the output when a

failure in the sensor connected to the controller input

occurs.

Lbd.t

Time interval for the LBD function. Defines the

maximum interval of time for the PV to react to a

control command. In minutes.

f.en

F Enable. Enables the utilization of F key to execute

the RUN function.

YES Enables F key to execute the RUN function.

NO Disables it.

m.en

M Enable. Enables the utilization of key to change

the control mode to Automatic or Manual.

YES key enabled.

NO key disable.

CALIBRATION CYCLE

All types of input are calibrated in the factory. If a new

calibration is required, it should be performed by a skilled

professional. If this cycle is accessed accidentally, do not

change its parameters.

pass

Password. This parameter is presented before the

protected cycles. See item Protection of Configuration.

(alib

Calibration. It enables the calibration possibility of

the controller. When are disabled, the related

parameters calibration are hidden.

inL(

Input Low Calibration. Enter the value

corresponding to the low scale signal applied to the

analog input.

ink(

Input High Calibration. Enter the value

corresponding to the full scale signal applied to the

analog input.

0vL(

Output Low Calibration. Analog output calibration.

Introduction of lower value present in the analog

output.

0vk(

Output High Calibration. Analogic output

calibration. Introduction of higher value present in the

analog output.

rstr

Restore. Restores the factory calibration for all inputs

and outputs, disregarding modifications carried out by

the user.

Cold Junction. Temperature of controller cold

junction.

Pas.(

Password Change. Allows defining a new access

password, always different from zero.

Prot

Protection. Sets up the Level of Protection. See

Table 03.
