5.2. Convection cooking control
The digital programmer circuit controls the ON-OFF time of
upper and convection heater inorder to control the oven cavity
temperature, see table and figure.
1. The digital programmer circuit generatesthe power relays
control signals at a specific timing as shown in table.
2. When the oven reaches the selected temperature, the
digital programmer circuit senses the temperature through
oven temp sensor and stops supplying 12V DC to the
power relays resulting in turn off of uper and convection
heaters. After the heaters have been turned off, the oven
temperature will continue to increase a while then decrease
as shown in figure.
3. When the oven temperature drops below selected
temperature, the digital programmer circuit senses the oven
temperature and starts supplying 12V DC to the coils of
5.3. Grill cooking control
1. The digital programmer circuit generates the power relays
control signals at a specific timing as shown in figure.
2. When the oven temperature reaches the predetermined
temperature, the digital programmer circuit stops supplying
power relays control signas resulting in both upper to
turnoff.
3. When the oven temperature drops below the
predetermined temperature, the digital programmer circuit
generates power relays control signals again at the timing
predetrmined.
NOTE 1:
After grill process, if oven temperature is higher than
power relays alternately again.
NOTE 1:
When convection is selected with temperature setting of
100-250°C, off period of both heaters is also programmed
while
oven temperature is lower than selected
temperature, asshown in figure.
NOTE 2:
After convection process, if oven temperature is higher
than predetermind temperature, fan motor rotates for 5
minutes at maximum time to cool the electric components
and oven.
predetermind temperature, fan motor rotates for 5 minutes
at maximum time to cool the electric components and
oven.
