ADC AD-410 ONE 1 Burner will not Ignite AT the Beginning of a Cycle, System Ladder Diagram

ONE (1) BURNER WILL NOT IGNITE AT THE BEGINNING OF A CYCLE

This condition can be caused by the following:

•DEFECTIVE DSI (Direct Spark Ignition) MODULE

•DEFECTIVE SPARK IGNITOR/FLAME-PROBE ASSEMBLY

•DEFECTIVE GAS VALVE

•INSUFFICIENT GAS PRESSURE

•DEFECTIVE ELECTRICAL HEAT CIRCUIT

Refer to the ladder diagram and the schematics provided with this machine for reference to the above listed information.

ONE (1) BURNER WILL NOT IGNITE DURING A DRYING CYCLE

This condition can be caused by the following:

•DEFECTIVE DSI (Direct Spark Ignition) MODULE

•DEFECTIVE SPARK IGNITOR/FLAME-PROBE ASSEMBLY

•DEFECTIVE GAS VALVE

•DEFECTIVE ELECTRICAL HEAT CIRCUIT

•LOSS OF GAS PRESSURE

Refer to the ladder diagram and the schematics provided with this machine for reference to the above listed information.

CONTROL POWER (Indicator/Control Power On Push-Button)

This “GREEN LIGHTED” push-button is for enabling the 24 VAC control voltage to the control circuits of the machine. This push-button indicator must be “ON” for the system to load or dry material.

Refer to the ladder diagram included with the dryer for the function of this push-button in the 24 VAC control voltage latching control circuit.

CONTROL POWER (Off Push-Button)

This “RED NON-LIGHTED” push-button is for disabling the 24 VAC control voltage to the control circuits of the machine.

Refer to the ladder diagram included with the dryer for the function of this push-button in the 24 VAC control voltage latching control circuit.
