COMPUTERS

These rethermalizers are equipped with Computer Magic III computers that have been modified for this specialized application. Although similar in appearance to standard Computer Magic III computers, the standard CM III computers will not operate the unit correctly. Only part number 806-8063 may be used in FBCR18 units and only part number 806-9352 may be used in FBKR18 units.

INTERFACE BOARD

An interface board is located in the component box directly behind the control panel. The interface board provides a link between the computer and the rethermalizer’s individual components without requiring excessive wiring, and allows the computer to execute commands from one central point. The part number for the interface board used in this equipment is 806-9295. A simplified illustration of the board is provided below.

The board contains a heat relay (K4) that switches 24VAC to the ignition and gas valve circuits when the computer heat logic circuit calls for heat. Relay K5 switches 120VAC to the blower motor when K4 closes. The water relay (K6) has two functions. First, it breaks the 24VAC circuit when the water level in the cookpot is below the lower water level sensor. This prevents the burners from firing when the unit is empty. The second function is to supply power to the normally open water
