ProMix 2KS Integration Specifics

Digital Outputs

See Automation Flow Charts, pages 55-59.

Purge_CC_Active: This output will remain High during the manual Purge or Color Change purge sequence. See the Color Change Charts (FIG. 109-FIG. 126) for fur- ther information.

Fill_Active: This output will remain High while the Pro- Mix 2KS is in the Mixed Material Fill at the end of a typi- cal color change sequence.

Mix_Active: This output will remain High while the Pro- Mix 2KS is in Mix mode. There may be alarm outputs while this output is High; these are typically High/Low Flow Warnings. Always monitor this output and the alarm outputs to provide feedback of the actual status of the ProMix 2KS. (See the Modbus charts in the Graco Gateway manual 312785.)

Mix_Ready: This output will remain High while there are no alarms and the ProMix 2KS is ready to go to Mix mode.

General Alarm: This output will remain High when any alarm is active. See Table 16 on page 115 for a com- plete list of alarms.

NOTE: It is important to monitor this output along with Mix_Active to understand the alarm’s true meaning.

Alarm_Potlife: This output will remain High along with the Alarm output when the potlife time has been reached for the active recipe. The Mix_Active output will drop Low, even if the Mix_Start input is High. This out- put will remain High until the potlife volume is dispensed or the ProMix 2KS completes a Purge or a Color Change. The Alarm Reset input will not stop this output but will silence the audible alarm on the EasyKey.

NOTE: The Alarm Reset

key will also reset the

audible alarm.

To dispense the potlife volume, the ProMix 2KS

Mix_Start input must be turned Off then back to High to spray material. At this point, Mix_Active, Alarm, and Alarm_Potlife outputs will be High until the potlife vol- ume is sprayed.

Digital Out Supply: This is the supply for the digital out- puts. It is the same supply for the digital inputs. (See Common under Digital Inputs, page 52.)

Analog Inputs

Flow Command: This is the positive side of the 0 – 10 Vdc signal. (See Common under Digital Inputs, page 52.) This input corresponds to the Flow Range setting in Advanced Setup Screen 5, page 41. For example, if the setting is 0 – 300 cc/min, the 0 Vdc analog input is 0 cc/min, therefore the 10 Vdc analog input is 300 cc/min.
