Gas Oven Control Board with CSA approval BW-TK081

Gas Oven Control Board with CSA approval BW-TK081
Basic information

This gas oven controller is applied to gas oven. The design consists of two GND
electrodes which can spark at the same time, two separated flame sensors and
one solenoid valve. CSA certification is requested.The rated operating voltage
is 120V and sparking rate is 60Hz.

Function , al description
 
With the oven being connected to power supplies, the control system can detect
automatically if the flame sensor circuit and valve circuit are in good
condition . The sparking won’t happen once the failure is detected in either
of the circuits.
 
After the automatic detection is passed, the controller system will start
sparking and turn on the gas valve. Sparking will stop once flame is detected.
Then the whole oven will be in operation. In the operation, the flame is sensed
all the time. If without flame being sensed, a total of 3 sparking attempts
shall be allowed and the interval of each sparking is 12±2s.

There are two burners for oven and the oven will be in operation with the flame
being detected in either of the two burners. Without flame being detected from
both burners, the controller will turn off the gas valve within 2s. The
sparking will begin after 12s and no more sparking after total 3 flameouts.
 
In the oven operation, simulated no flame signal is released every minute to
detect the status of flame sensing circuit which will improve the security of
end users. Furthermore,the flame will be sensed by watch dog chip and the main
chip at the same time. The gas valve will be controlled by these two chip as
well.
 
The oven using this controller has been approved by CSA certification per the
standard of IEC60730-2-5.
