Solid State Relay - K11 Bake and Convection Elements (Double Wall Oven Only)
The K11 solid state relay is a 240 VAC, dual 40 amp relay. This relay supplies L1 voltage to the lower oven’s bake and convection elements (24 VDC control voltage).
Solid State Relay - K12 Broil Elements: Inner and Outer (Double Wall Oven Only)
The K12 solid state relay is a 240 VAC, dual 40 amp relay. This relay controls the L1 voltage to the lower oven’s inner and outer broil elements. The control board sends 24 VDC to the K12 SSR to independently “open” and “close” each side of the SSR, over 100 times per second, for absolute temperature control.
Speaker
The speaker provides audible feedback to the operator whenever a key is pressed or a task (such as a cook cycle) is completed, etc. See page 4.1 for adjustments.
Temperature Switch (Lower Oven)
The temperature switch uses a
Transformer, Clock, 12 VAC
The 12 VAC transformer supplies voltage to the Speedcook oven clock. For Gen 2 ovens, the 12 VAC transformer is located on the relay board (terminals
Thermostat, Cooling Fan Control
The cooling fan control thermostats are normally- open snap switches that will close if the temperature within the upper electrical compartment exceeds 140°F (60°C), or if the temperature within the lower electrical compartment exceeds 160°F (71°C). They supply voltage from the terminal block to the upper and lower cooling fans, allowing them to operate
if they are needed after the CookWheel or selector switch has been turned to the off position. If either thermostat closes, both cooling fans will be powered on.
USB Port
The USB port allows the oven operator to load software updates from a USB drive. For instructions, see page 4.3.
Connecting the USB Board (Gen 1 Oven)
The USB board connects to the control board via a
