Lincoln 1200, 1400, 1000 operating instructions Finger Housing Baffle Plate Adjustements

FINGER HOUSING BAFFLE PLATE ADJUSTEMENTS

The finger housing has a baffle mounted inside to balance the air flow to the rear and front of the oven. If the product is cooking more or less in the rear of the oven than in the front, it is possible the finger housing baffle needs to be adjusted. If it is deemed necessary to adjust the air balancing baffle, be sure to adjust all eight (8) finger housing to exactly the same opening. Determine if more air (heat) is required at front or rear of oven then open or close off that air by bending the baffle in the proper direction. See drawing above.

PROGRAMMING THE DIGITAL ADVANTAGE 1450 SERIES TOUCH PAD

INTRODUCTION – START-UP AND SUT DOWN

For the operator, the panel has a power up, run, and program menu modes. To start the oven, turn the power switch on. To shut down the oven, turn the power switch off.

FRONT PANEL LAYOUT

The front panel contains four (4) momentary push-buttons: TEMP, TIME, UP &

DOWN. There is a 2 line x 16 character VFD display.

TEMPERATURE SETPOINTS

For Digital Advantage ovens, there is one setpoint. To enter the setpoint mode, press the TIME & TEMP buttons together and hold for 5 seconds. Pressing the UP or DOWN push-buttons will raise or lower the temperature to the desired setting. In the Fahrenheit, F mode, the temperature is adjusted in 5 degree increments. When in Centigrade, C mode, the temperature adjustment will be in 1 degree increments. Pressing and holding the UP or DOWN keys will allow the settings to “roll” at a much faster rate. When the

desired temperature is indicated, release all keys. After 5 seconds, the selected setpoints will be stored and remain in memory.

TIME SETPOINTS

There is one setpoint for the conveyor speed. Enter the setpoint mode as mentioned above. The speed can be set as follows:

1:00 to 9:55 in 5 second increments 10:00 to 12:45 in 15 second increments 13:00 to 19:30 in 30 second increments 20:00 to 30:00 in 1 minute increments

JUMPING BETWEEN MENUS

Pressing the TIME push-button while in the TEMP setting mode (and vice versa) will cause the menu selection to jump over to that mode.

DIAGNOSTIC MESSAGES

The Digital Advantage ovens have diagnostic messages within the control. In the unexpected event that there is a failure in the oven operation, the following messages will appear in the control.

OPEN PROBE

This occurs when there is no temperature being sent to the controller from the baking chamber.

SHORTED PROBE

This occurs when a constant temperature signal (as opposed to the normal cyclical cavity temperature) is being sent to the controller from the baking chamber.

CAUTION: This message can also occur when there is no gas supply to the oven. If the oven does not detect a temperature fluctuation in 5 minutes, the error message will appear. Be sure to check the gas valve and gas hose for proper connections.

BELT JAM

This occurs when the conveyor motor fails.
