Controller N1200

NOVUS AUTOMATION 7 / 13

ovkl

Output High

Limit

Upper limit for the control output - Maximum

percentage for

the control output when in

automatic mode and in PID. Typically configured

with 100 %. Default value: 100 %

sfst

Softstart

SoftStart Function –: Time in seconds during which

the controller limits the MV value progressively

from 0 to 100 %. It is enabled at power up or when

the control output is activated. If in doubt set zero

(zero value disables the Soft start function).

Sp.a1

Sp.a2

Sp.a3

Sp.a4

ALARM SETPOINT: Tripping point for alarm 1, 2, 3

and 4. Value that defines the point of activation for

the programmed alarms with the functions “

” or

“

”.

For the alarms configured with Differential type

functions, this parameter defines deviation (band).

Not used for the other alarm functions.

CYCLE OF PROGRAMS

Pr.tb

Program time

base

Defines the time base that will be used by all Ramp

& Soak programs.

Se(

- Time basis in seconds;

Min

- Time basis in minutes;

Pr n

Program

number

Selects the ramp and soak profile program to be

edited/viewed. The sequence of parameters that

follows refer to this selected program. Total of 20

programs possible.

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

(the

program progresses regardless of the difference

between PV and SP).

Psp0

Psp9

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

define the Ramp and Soak profile segments.

Pt1

Pt9

Segments durations

, 1 to 9: Defines the time of

duration, in second or minutes, of

the segments of

the program being edited.

Pe1

Pe9

Program event

Alarms of Event, 1 to 9: Parameters that define

which alarms are to be activated during the

execution of a certain program segment. The alarms

chosen must have its function configured as “

.”

(See Table 3)

Link Program

Link Programs: Number of t

he next profile program

to be linked following the current program

. Profiles

can be linked together to produce larger programs

of up to 180 segments

0 – do not link to any other program.

CYCLE OF ALARMS:

Fva1

Fva2

Fva3

Fva4

FUNCTIONS OF ALARMS 1 to 4. Defines the

functions for the alarms among the options of the

Table 3.

bla1

bla2

bla3

bla4

BLOCK ALARM 1 TO 4: This function blocks the

alarms when the controller is energized.

YES

- enables initial blocking

- inhibits initial blocking

When enabled, the alarm will not be active at

power-up, waiting for PV (Process Variable) to

reach a non-alarm situation. From this point on the

alarm will be free to actuate should a new alarm

situation occur.

xya1

ALARM HYSTERESIS: Defines the difference

between the value of PV at which the alarm is

xya2

xya3

xya4

triggered and the value at which it is turned off (in

engineering units).

A1t1

A2t1

A3t1

A4t1

Alarm Time t1

Defines the temporization time t1, in seconds, for

the alarms. Defines the temporization time t1, in

seconds, for the alarms time functions. The value 0

(zero) disables the function.

Refer to Table 4 for configuring this parameter

timed functions. The value 0 (zero) disables the

function.

Refer to Table 4 for configuring this parameter.

A1t2

A2t2

A3t2

A4t2

Alarm Time t2. Defines the temporization time t2,

in seconds, for the alarms time functions. The

value 0 (zero) disables the function. Refer to Table

4 for configuring this parameter

flsh

Flash

Allows visual signalization of an alarm occurrence

by flashing the indication of PV in the operation

level. The user chooses which alarms are to be

associated with this feature.

CYCLE OF SCALE

Type

INPUT TYPE: Selects the input signal type to be

connected to the process variable input. Refer to

Table 1 for the available options.

fltr

Filter

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.

Dppo

Decimal Point

Selects the decimal point position to be viewed in

both PV and SP

vnI t

Unit. Temperature indication in ºC or ºF:

root

Square Root

Square Root Function. Applies the quadratic

function on the input signal, within the limits

programmed in “

SPLl

” and “

spkL

.”

YES

Enables the Function

Does not enable the Function

The indication assumes the lower limit value when

the input signal is below 1 % of programmed span.

Parameter available for lineal inputs only.

0ffs

Offset

SENSOR OFFSET: Offset value to be added to

the PV reading to compensate sensor error.

Default value: zero.

e.rsp

Enable Remote

Enables remote SP.

YES

Enables the Function

Does not enable the Function

This parameter is not displayed when the remote

SP selection is defined by a Digital Input.

rsp

Remote SP

type

Defines the signal type for the remote SP.

0-20

current of 0-20 mA

4-20

current of 4-20 mA

0-5

voltage of 0-5 V

0-10

voltage of 0-10 V

Parameter displayed when remote SP is enabled.

rsll

Remote SP

Low Limit

REMOTE SETPOINT LOW LIMIT: used in

conjunction with the

rSxL, scales the remote SP

input defining the initial value in the remote SP

indication range.

Parameter displayed when remote SP is enabled.
