DATA ACCUFLOW SCREEN


DATA ACCUFLOW SCREEN

To use AccuFlow, you must set up the pulsing pump supply (refer to Table 1, " AccuFlow Color Data " ). All other items are for display only.

Table 1. AccuFlow Color Data

ACCUFLOW COLOR DATA DESCRIPTION

Color Valve Number

This item is the number of the selected color valve.

Pulsing Pump Supply(boolean)

This item, when set to YES, allows AccuFlow to use the Pulsing Pump Gain Modifier for colors whose supply pressure is expected to pulse or change by a significant amount on a regular basis.

Maximum Controllable Flow(cc/min)

This item is what AccuFlow has determined to be the highest attainable flow rate within the linear portion of the yield curve. This number serves as the tenth point in the calibration table. This number must be greater than the highest used flow rate preset for this color. This parameter is automatically determined and cannot be changed.

Hysteresis(cc/min)

This item, determined during calibration, is the difference between two midlevel flow rate readings; one when approached from zero flow rate and the other when approached from maximum flow rate. Hysteresis is not used for any closed loop operations and the sequence can be disabled during calibration. This parameter is automatically determined and cannot be changed.

Last flow error

This item tells what the percentage difference was between setpoint and actual flow the last time this color was sprayed in production. This is very useful to determine that a system is giving good paint quality jobs. It is used as a quality indicator to determine whether the system is performing good quality paint jobs. This parameter is automatically determined and cannot be changed. If this value exceeds the alarm parameter Max error from setpoint , the alarm "Flow rate average error high" is displayed. This value is updated during production operations only. It is only valid if the color displayed has been used in a production cycle and the current job cycle does not include a color change pushout cycle. A typical value is in the range of 2 to 20 %. This is only updated if the value of max error from set point is larger than zero.

Auto cal result code(text)

This item is a status updated after a calibration and during production to indicate any problems encountered during the calibration sequence or any adaptations during production. This parameter is automatically determined and cannot be changed.

Average cal yield((cc/min)/count)

This item is the average of the slopes of lines between individual refer ence calibration points and calibration origin. The slopes of the lines themselves represent the volume of fluid achieved per unit change in regulator pressure. The range for this parameter should be between 0.5 - 2.0. No default is given as this is color specific and the value is determined automatically during calibration. This value cannot be changed.

Average dyn. yield((cc/min)/count)

This item is the average of the slopes of lines between individual dynamic calibration points and calibration origin. This can be used as a snapshot status of that color's current behavior when compared with Average cal yield. The range for this parameter should be between 0.5 - 2.0. No default is given as this is color specific and changes throughout production to reflect the current paint characteristics. This parameter is automatically determined and cannot be changed.
