SETUP COLOR CHANGE SCREEN


SETUP COLOR CHANGE SCREEN

You can set up the color change system parameters from the SETUP Color Change screen.

Table 1. Color Change System Setup Items

COLOR CHANGE SETUP ITEM DESCRIPTION

Automatic Color Change

This item enables the automatic color change option in the controller to function in production mode.

Periodic Gun Cleaning

This item determines whether or not the gun will be cleaned at predetermined intervals.

Gun Cleaning Job Count

When periodic gun cleaning is set to YES, the gun cleaning job count is the number of jobs to be painted before an automatic gun cleaning cycle is performed.

Pushout

This item is used to enable the paint pushout option. Paint pushout identifies the time when the paint in the paint lines equals the paint needed to finish painting the current job. When pushout is executed, air or solvent is put into the paint line instead of paint in order to save paint.

The information that controls when to start the pushout is maintained by the selected color value. If the calculated GUN=ON time for a specific job is not available then no pushout is performed. In this case, a full-line purge and color change cycle will be performed.

NOTE Pushout calculations only include the job preceding a color change.

Pushout When Color Unknown

This item is used for a paint pushout to begin when the next color is unknown. Then, when the robot is given the next color, either a color change or a re-fill will be performed.

If set to YES, a pushout will be performed regardless of whether or not the next spray color is known provided the cell controller asserts the Pushout signal.

If set to NO, the next color to spray must be known or the robot will not pushout, regardless of the cell controller signal.

Clean When Color Unknown

This item is used to enable the automatic cleanout of the paint lines option. In production mode, when clean when color unknown is set to YES, and the next color is unknown and the lines are pushed out, the cleanout cycle will be executed. By setting this option, you can save color change time when the next color becomes known. It also automatically clears the lines for breaks in production.

Find Last Gun Off

This item, when YES, turns on an output signal when the last gun off is executed for a job in production mode. This output will turn off when the job is completed.

Start ColorChg at Last Off

This item allows you to run a color change cycle starting at the last gun off signal. The find last gun off option must be set to YES to use this option.

Color Output Select By

This item determines whether the color output is selected by a 5 BIT binary value or a 32 BIT discrete value.

If 5 BIT binary is selected, the GOUT for a color valve (0-31) will use 5 bits (F4 function key) and a color enable output.

If 32 BIT digital is selected, the GOUT for a color valve (0-31) will use 32 bits (F5 function key) with each color valve assigned an output bit.

Wet Valve Delay Time

This item is used when a color change cycle is executed. It represents the amount of time, in milliseconds, that will exist between the selection of a wet valve and a dry valve. The wet valves are the valves of the 16 bit group that control fluid instead of air. If you are turning off a wet valve, the delay occurs after the wet valve is turned off, then the other valves in the step are set. If you are turning on a wet valve, the other valves are set first, then the delay occurs, then the wet valve is turned on.

CC Resume Required

This item defines whether the color change cycle will pause or abort when an error or fault is encountered.

If set to YES, the color change cycle will pause when an error or fault is encountered. When the error or fault is reset, and the continue input signal is triggered, the color change cycle will continue.

If set to NO, the color change cycle will abort when an error or fault is encountered.

When the error or fault is reset, the color change cycle will be cancelled.

Remote CC Stack Option

Group Output Number

This item defines the group output number used for the Remote CC Stack color valve outputs. This can be defined from 1 - 16 valves for this remote stack.

The default = 0, disabled.

1st Remote Valve Number

This item defines the first valve number for the Remote CC Stack. The Controlled Start Setup item, No. of Color Valves is the total number of all color valves on the Regular CC Stack and on the Remote CC Stack.

Example: Regular CC Stack = 16 valves Remote CC Stack = 16 valves No. of Color Valves = 32 1st Remote Valve Number = 17

The default = 0, disabled.

PLC Permissive Input Number

PLC Permissive Input Number - used to define the digital input number for the Remote CC Stack Permissive. When this input is defined (not 0), the robot will wait to execute the Fill or Refill cycle until this input is asserted. The Color Change Status display will be updated to indicate Waiting for Ok to Fill. The default =0, disabled.
