Hello all. We are conducting a life test and wanted to use Labview to cycle frypot burners and a water circuit. We are at a snag on how to code the cycling and wanted some suggestions. Here is our situation:
1. Activate the burners to heat oil until 350°F.
2. At 350°F, turn off the burners and activate the water circuit to cool down the oil.
3. At 315°F, turn off the water and activate the burners again.
Steps 2 and 3 repeat indefinitely.
We thought we could use Case Statements to handle this, but we don't see how to handle step 2 if we use this method. We thought of the following:
Case 1: . . . 350 <this would activate the burners until 350°F>
Case 2: 315..350 <this would activate the water circuit>
Case 3?: . . .315 <this case would be another burner activation to keep the burners going if the oil temperature gets below 315. Would this even be needed?>
As you can see, we have an issue here in that the water circuit would turn on while the burners are going using the logic we have now. The main problem is getting past the startup--heating from room temperature to 350. If we were just looping between 315 and 350, we could work with this, but that initial heatup is confusing us as to what to do.
Is there another way to do this besides Case Statements?
Thanks.
