I have built this circuit over and over and i cant get the mixer motor to come on and turn off when specified. the problem is to be done in logix pro. i could use some help with a schematic if at all possible.
8-38 Two ingredients, A and B, are to be heated and mixed. Two pumps, P1 and P2, provide the necessary pressure to send the ingredients through the lines. The procedure is as follows:
The start pushbutton is pressed to start the process and pump P1.
After 100 gallons of ingredient A are pumped into the tank, pump P1 stops automatically and the heater is automatically turned on.
The heater is automatically turned off after 2 seconds, and pump P2 is energized.
Ingredient B is pumped into the tank, by pump P2, until the liquid reaches the high-level sensor.
The mixer motor starts automatically and runs for 10 seconds.
After the mixer motor stops, P3 discharge pump starts automatically and runs until the low-level sensor is actuated.
The process stops.
The process can be stopped at any time, by means of the stop button, without loss of the counter accumulated count or the timer accumulated time.
The idle light is energized whenever the process is stopped.
The run light is energized whenever the process is in operation.
The full light is energized whenever the tank is full.
