Calibration

State

Indicates that during a job calibration,

the unit is waiting for the user to

manually adjust the valve position to

the desired 100% open position.

Use the buttons on the posi-

tioner to adjust the valve to the

desired fully open position. See

the explanation of Jog Calibrate

in the QUICK-CAL section of

main document for operation.

Command

Loop Range

Too Small

Warning

Indicates that during a Command

Loop (Analog Input) Calibration, the

difference between the signal at 0%

and the signal at 100% was too small.

The system is designed to accept a

difference greater than 2 mA.

Recalibrate making sure to use

a larger difference between

command signal limits. The dif-

ference must exceed 2 mA.

Warning

Indicates that during Command Loop

(Analog Input) Calibration, the 100%

signal was out of range.

The system is designed to

accept a signal between ap-

proximately 3.5 mA and 22 mA.

Recalibrate making sure to set

the limits inside that range.

Indicates that during Command Loop

(Analog Input) Calibration, the 0%

signal was out of range.

The system is designed to

accept a signal that is between

approximately 3.5 mA and 22

mA. Recalibrate making sure to

set the limits inside that range.

signal at 100% was too small.

Recalibrate making sure to use

a larger difference between

Pressure

Sensor Board

Present/Ab-

sent

Indicates pressure sensors are physi-

cally present in the positioner. Other-

wise the sensor option has not been

installed. The sensors are required for

many of the diagnostic features.

Pressure sensors are available

to install in the device. Contact

your Flowserve sales repre-

sentative.

N/A

None

Analog Output

Board Pres-

ent/Absent

Indicates an analog output board is

physically present in the positioner.

Otherwise the board option has not

been installed.

An analog output board is

available to install in he device.

See your Flowserve sales

representative.

N/A

None

Pressure

Control

Locked/

Inactive

Indicates that the positioner feedback

sensor is rotating clockwise to close.

This affects the fail safe position of the

valve in the event of linkage failure. In

normal configurations, a spring will

turn the sensor counter-clockwise

upon release of the feedback linkage.

Use the Valve Stability DIP

switch to toggle this mode on

or off. If high friction is set and

this indicator never comes on,

the error band limits may need

to be adjusted.

Reversed/

Normal

Indicates that the positioner feedback

sensor is rotating clockwise to close.

In normally configured position-

ers, a spring will turn the sensor

counter-clockwise upon release of the

feedback linkage. This affects the fail

safe position of the valve in the event

of linkage failure.

Ensure the feedback sensor

spring will lead to a proper fail

safe position. If needed, an

optional internal biasing spring

is available that can change

the direction of failure position

if the feedback linkage should

break.
