ELECTRONIC SPARK IGNITION

COOKTOP BURNER OPERATION

The top burner spark ignition system is initi- ated when the burner control is turned to the LITE position.

120 VAC is supplied through the ignition switch from the L1 side of the circuit to the direct spark ignition control at input J1-9on the control. The circuit is completed through output pin J1-4to the neutral side of the circuit.

Cooktop Strip Circuit

This 120 VAC is detected by the control, and generates two sparks-per-second to all of the top burners. Note that in the strip circuit be- low, 120 VAC is present at the control at all times through input pin J1-10, and output pin J1-4.

120 VAC is required to:

a)Monitor the internal self-diagnostics of the control board.

b)Monitor the flame safety circuits to both of the oven burners.

NOTE: The top burners are operator-moni- tored, and do not require electronic monitor- ing.
