SOFTWARE SETUP

6.2.2.10 RATIO SET

This parameter is a Ratio Multiplier that is applied to the

input command signal. It ranges from .2 to 2.  A setting of 1

results in no change to the input command signal.

6.2.3 CLOSED LOOP CONTROL PARAMETERS

6.2.3.1 PV UNITS

This is a four character label that will be displayed with the

process variable and it’s associated parameters.  It is entirely

configurable by the operator.  When selected for update, the

first of the four characters is highlighted.  The 

 / 

 selections

are used to scroll through the available characters: A-Z, a-z,

space, -, % and /.  Selecting 

E

nter will set the displayed character

and continue to the next.  When all four characters have been

set, the label is saved.  At anytime prior to the final character

being set, 

C

ancel may be selected and no change to the label

will be made.

6.2.3.2 PV MAX

This is Process Variable reading that is to be associated with

the maximum input signal of 20ma or 5V, and local setpoint.

6.2.3.3 PV MIN

This is Process Variable reading that is to be associated with

the minimum input signal of 4ma or 1V, and local setpoint.

6.2.3.4 PV DAMP

Dampening is the amount of time over which the Process

Variable input signal is averaged.  The setting may range from

0 seconds (no dampening) to 25 seconds. This is used to

smooth out rapid fluctuations of the input signal.

6.2.3.5 PV HI ALRM

This is the Alarm level that signifies that the Process Variable

signal is too high.  When the process variable input rises

above this level an alarm is generated.

6.2.3.6 PV LO ALRM

This is the Alarm level that signifies a Process Variable signal

is too low.  When the Process Variable input falls below this

level an alarm is generated.

6.2.3.7 PV ALRM DB

This parameter determines when the Process Variable High

and Low Alarms are cleared.  The Process Variable signal

must rise above the Low Alarm level by the Deadband

amount in order to clear a Process Variable Low Alarm.  The

Process Variable signal must fall below the Process Variable

High Alarm level by this amount to clear a Process Variable

High Alarm.  The parameter may be set from 0.3% to 25% of

the Process Variable signal range.

6.2.3.8 PV LOS ACTION

This is the action taken when the Process Variable input

signal is lost.  It may be configured as

LOCK – actuator locks in place at its current position

DTZ – actuator drives to the Zero position

DTS – actuator drives to the Span position

DTP – actuator drives to a user selected position

6.2.3.9 PV LOS POS

This is the position to which the actuator will drive when the

PV LOS ACTION parameter is set to Drive To Position and

that signal is lost.

6.2.3.10 PROPOR GAIN

This is the gain applied in the PI control loop of the Closed

Loop control scheme.  It tells the actuator what percentage

of the difference between the Set Point and the Process

Variable signals to use as the step up or down. The

percentage is equal to 100 divided by the PROPOR GAIN

setting. It may be set from 0 to 255%. A gain setting of

100% results in the step up or down being equal to the

difference of the two signals.

6.2.3.11 INTEGRAL TIME

This is the time over which the correction of the PI control

loop is applied to the system.  It ranges from 0 to 60

minutes.  The correction to be made to the system is

calculated and it is applied incrementally over the Integral

time.  The correction and the size of its incremental

application is continually calculated and applied to the

system.  A setting of 0 minutes would apply any required

correction immediately rather than spread out over a period

of time.

6.2.3.12 LOC/RMT SP

This parameter configures whether the Process Variable set

point of the system is obtained locally (SP) when set to

LOCAL, or if it is obtained from the input signal (on input pair

number 3) when set to REMOTE.

6.2.3.13 SET POINT

When LOC/RMT SP is set to LOCAL, this is the Local Set

Point Parameter that the system uses.  It is only available

when REM SP is set to REMOTE.

6.2.3.14 SET POINT DEV ALRM

This is the percentage of the Process variable Signal by which

the Set Point and the Process Variable signal may differ

before an alarm is triggered.
