Automatic Ignitor Sensor System
Basic System Model S6E
The heart of the system is the SmartBake® ISPU-3 solid-state module that provides the high voltage spark to ignite and monitor a direct-fired oven burner. A small electric current flows from the ignitor to the burner, when the burner is lit. The ISPU-3 generates and monitors this electric current. The presence of electric current indicates burner flame is present. The ISPU-3 module keeps the burner solenoid fuel valve open as long as the burner flame is present. Should the burner flame fail, the ISPU-3 module reinitiates the high voltage ignition spark for approximately 10-seconds. If the burner flame is not reestablished at the conclusion of the 10-second period, the ISPU-3 module closes the solenoid fuel valves, shutting off gas to the burner. Coinciding with a flame failure of the burner the two color LED on the SmartBake® S6E unit turns red, indicating that the burner is down on safety lockout and is not functioning properly. In order to reset the ISPU-3 module and burner, the switch located on the SmartBake® S6E unit must be turned to the reset position for approximately 10 seconds and then turned on again to re-ignite the burner. If the burner fails to re-ignite, it should be inspected to determine the reason for the malfunction. When the LED turns green, this indicates that the burner is turned on and firing properly. In addition, the S6E unit comes equipped with a 24 VAC input port to allow maintenance personnel to test the burner operation.
