a.Major Burner Components

1)Burner Controller Module (BCM)

The burner controller module (BCM) provides effective burner flame safeguard control through adjustable purge and trial-for-ignition timing. The BCM insures that ALL dryer safety switch circuits are closed, delays ignition to allow the combustion chamber to vent, and insures that a healthy pilot flame is established before opening the main gas valves. Five (5) L.E.D.’s (light emitting diodes) on the cover of the BCM allow for easy troubleshooting. Dip switches on the back of the module allow for easy programming.

(a)Dip Switches Selections

(1)Loosen the two (2) screws on the burner control module cover and pull the module cover off of its base. The dip switches are on the back of the cover.

Switch #1 - Recycling Mode

With this switch in the “ON” position, the burner will recycle the ignition sequence once during each drying cycle after a burner fan air switch or main flame failure, but only if the failure occurs more than 35-seconds after ignition. If this switch is “OFF," the burner will lock out at once.

Switch #2 - Intermittent Pilot

This switch is “ON” for intermittent pilot or “OFF” for interrupted pilot. ADC utilizes intermit tent pilot so that the pilot flame stays lit during the entire drying cycle. With interrupted pilot, the pilot flame would go out once the main flame is established. This is used mainly on oil burners lit by a gas pilot.

Switch #3 - Trial for Ignition (TFI) Time

When this switch is “ON” a Trial for Ignition (TFI) of ten (10) seconds is set. If it is in the “OFF” position, the TFI is five (5) seconds. The Trial for Ignition Time is the length of time that the pilot is given to light. A ten (10) second TFI is best for the dryer.

Switch #4, Switch #5, Switch #6, Switch #7- Purge Time

Switch #8 is for post purge selection. With switch #8 in the "ON" position, the post purge time will be 15-seconds. When switch #4, switch #5, switch #6, and switch #7 are in the “OFF” position, the post purge time will be 0- seconds.
