Temperature Calibration; Conveyor Speed Calibration - Lincoln Impinger II 1100 Series Service Manual

Operation

Temperature Calibration:

1. Place your temperature meter probe directly on the conveyor belt centered in the oven cavity front to back and left to
right.
2. Turn oven ON; set oven temperature to 500 F (260 C). Allow 30 minutes preheat for temperatures to stabilize in oven
cavity.
1. Access the Calibration Mode to enter and change the "Offset". The average temperature value on your meter while the
oven is set for 500 F (260 C) and blowers running at 100% is the value that you will enter.
Note: For best result, we recommend disconnecting the drive coupling to stop the conveyor from moving. Insert the
temp wire into 1/4" (6mm) tubing with the tip of the wire exposed. Do not place a pan or any other object around the
tip as this will change the air flow and accuracy of this reading.

Conveyor Speed Calibration:

1. Conveyor speed is verified by placing an object on the conveyor belt and timing the travel starting from when it first
enters the chamber to when it first exits the chamber. This is also known as leading edge in to leading edge out. Pizza
Pans are commonly used for this test since they can handle the heat and are usually available on site.
2. Before checking conveyor speed, allow conveyor to run for 10 minutes. If speed is off 25%, verify the control board is
initialized correctly for (1100).
3. If speed is a few seconds off, bring up the Conveyor Calibration screen on the controller (Down Button while in the
Calibration Mode). Increase the value to increase the speed and decrease the value to decrease the speed (.003 is
approximately 1 second). Default value on the screen would be 1.000. A new setting of 1.003 would increase speed by 1
second. A new setting of 0.997 would decrease speed by 1 second.
