Page 9: Display Information
DISPLAY INFORMATION When operating the oven, there are three levels of access: 1. Store Level - General employees would know these functions and how to change them. While the oven is running, enter this mode by holding the DOWN and UP arrows ( simultaneously for four seconds. The TIME display goes blank and the TEMP setpoint is displayed. Adjust with the DOWN or UP arrows. The ENTER button ( ) toggles between TIME and TEMP. The parameter that can be adjusted is displayed, the other is blank. When TIME and TEMP are adjusted as needed, wait five seconds and SAVE is displayed. The values are accepted and the controller begins controlling to these new values. The conveyor continues to operate at the same speed until a new value is accepted. The temperature control output should be OFF during changes. - Page 10 BAKE TIME VERSUS TEMPERATURE 1. Bake time is actually conveyor speed and is defined as the time the product is actually in the oven. This is measured by noting the time when the leading edge of the product enters the oven and the time the leading edge of the product leaves the oven. This is adjusted by using the conveyor speed controller. 2. Bake temperature is adjusted by changing the setpoint of the temperature controller to the desired bake temperature. When the oven reaches the desired temperature, the red dot in the lower right corner of the temperature display will turn off and on as the controller maintains the temperature. 3. When establishing a bake time and temperature for a given product, the general rule shall be as the bake time increases the bake temperature decreases and the reverse is also true; increase temperature, decrease time. However, there are limits to the above rule. Going to extremes will result in a burnt exterior and raw interior or it will result in a very light color but over-baked product. 4. Once a good bake has been established, the fine adjustments should be made by holding either the bake time or bake temperature constant, then varying the other.

CONVEYOR BELT TENSION The conveyor belt of the Ultra-Max Conveyor Oven does not have a tension adjustment. If the belt becomes too loose, a link will have to be removed to tighten. A belt that is too tight will also cause operational problems due to excessive drag. We suggest that you have a qualified service technician perform this adjustment. CAUTION Careful consideration should be exercised prior to removing a belt link because a belt that is too tight will impede the smooth operation of Remove the outside master links on the right and left the conveyor. sides of the conveyor belt. Remove the center splice clips next. CONVEYOR BELT LINK REMOVAL An entire link can be removed with the conveyor assembly either in or out of the oven. This may be necessary as the belt stretches after continuous use. Following are the necessary steps for removing links: 1. Move the splice clips to either end of the oven for easy access. 2. Unhook the splice clips using long nose pliers. 3. Unhook the full link to be removed and slide it out. Do not discard the link removed as it may be used for making spare splice clips. Unhook the end loop and pull up on the link section. 4. Reconnect the inside splice clips.
