This Lab may be performed using jumps or subroutines, your choice. Process Problem: A mixing vat can use one of two recipes for mixing cleaning products. A selector switch chooses the recipe. The Start Pushbutton runs the selected recipe. If the Stop Pushbutton is pressed, the recipe aborts by shutting all related valves, running a drain cycle, and running a vat cleaning cycle. Window Cleaner: Water - Open valve_1 for 15-seconds Ammonia - Open valve_2 for 5-seconds Blue dye - Open valve_3 for 1-second Bathroom Cleaner: Water - Open valve_1 for 10-seconds Bleach - Open valve_4 for 5-seconds Green dye - Open valve_5 for 1-second At the end of each recipe fill, the Mixer_Motor runs for 3- minutes after which the Drain_Valve is opened to feed the bottle filling line until the Vat_Empty limit is reached. Then the Drain Valve is closed. If the recipe selector is changed, a cleaning cycle is performed. Water - Open valve_1 for 20 seconds, Mix for 5-minutes, and drain until empty This Lab may be performed using jumps or subroutines, your choice.
