N960 Controller

NOVUS AUTOMATION 3/6

T SP

Level Time: Time interval in minutes, that the process

must remain in the temperature defined in SP.

Adjustable from 0 to 9999.

It is available when the Rate option is selected in the

Pr.ty

parameter of the Input cycle.

E pr

Enable

Program

Program Execution – It determines the level and ramp

program execution.

Yes

Executes program

Does not execute program

With enabled outputs (

RvN

YES), the selected

program immediately enters in execution.

It is available when the Pr option is selected in the

Pr.ty

parameter of the Input cycle.

Rvn

Run

Screen that enables or disables action of the controller

over the process. It acts as a switch, turning the

controller on or off.

YES

Outputs enables.

Outputs not enabled.

TUNING LEVEL

Atvn

Auto tune

AUTO-TUNE: It enables automatic tuning of the PID

parameters (

). See chapter Determine PID

Parameters herein and at

www.novusautomation.com

for more details.

YES

-Auto-tune enable

-Do not execute auto tune

Proportional

band

PROPORTIONAL BAND: Value of the term P of the

control mode PID. In percentage of the maximum

span of the input type.

When set to zero (0), control action is ON/OFF.

Adjust of between 0 and 500.0 %.

Integral rate

INTEGRAL RATE: Value of the term I of the control

mode PID, in repetitions per minute. This constant is

not used when controller is set to ON/OFF action

(

). Adjustable between 0.00 and 55.20.

derivative time

DERIVATIVE TIME: Value of the term D of the control

mode PID, in seconds. This constant is not used when

controller is set to ON/OFF action (

). Ajustable

between 0 and 250.

Cycle time

CYCLE TIME: Pulse Width Modulation (PWM) period

in seconds. This constant is not used when controller

is set to ON/OFF action (

). Adjustable between

0.5 and 99.99

KySt

HYSterisis

CONTROL HYSTERESIS: Is the hysteresis for

ON/OFF control (set in temperature units). This

parameter is only used when the controller is in

ON/OFF mode (

A1SP

A2SP

Alarm SP

SETPOINT for Alarm 1 and 2: Tripping point for

alarm 1 and 2.

PROGRAM LEVEL

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

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 the program segments. It defines the

duration in minutes, of each of the 9 program

segments. Configurable between 0 and 9999 minutes.

Pe1

Pe9

Program

event

Program Segment Alarm (Event Alarm). Parameters

that define the alarm must be activated during the

execution of a certain program segment:

OFF Do not activate alarm in this segment.

A1 Activate alarm 1 when program reaches this

segment.

A2 Activate alarm 2 when program reaches this

segment.

A1A2 Activate alarms 1 and 2 when program

reaches this segment.

The alarms chosen must have its function configured

as “

”.

rPt.P

Repeat Program

It determines the number of times the program must be

REPEATED, besides the initial execution. Configurable

between 0 and 9999 times. After the last execution, all

controller outputs are turned off (

RvN

OFF

INPUT LEVEL

Type

tYPE

INPUT TYPE: Selects the input signal type to be

connected to the process variable input. Refer to

Table 1 for the available options.

This must be the first parameter to be configured.

Dp.po

Decimal Point

DECIMAL POINT. Defines the decimal point position.

Vnit

unit

UNIT: Defines the indication unit in Celsius or

Fahrenheit

(

Degrees Celsius (°C);

Degrees Fahrenheit (°F);

A(t

ACtion

CONTROL ACTION:

Reverse action. Generally used for

heating.

Dir

Direct action. Generally used for

cooling.

f.fnc

F Key Function:

It allows to define a function for the F

key. Functions available are:

Off

– Not used / No function assigned;

RvN

– Commands control and alarm outputs (function of

the

RvN

parameter);

kprg

–

Interrupts the execution of the ramp and soak

program;

epr

–

Triggers the execution of the ramp and soak

program;
