Operating Instructions
Ignition Control Operation
Power Up
After 24 VAC is applied to the ignition control pins
24V and GND, the Diagnostic LED on the ignition control will turn orange/yellow. If a fault is detected the ignition control will enter Lockout Mode. If no faults are detected, the Diagnostic LED will turn
Green and the ignition control will enter Standby
Mode.
Standby Mode
While in Standby Mode, the ignition control will continually monitor the system for faults. Once
24VAC is applied to terminals TH and GND on the control, the ignition control will enter Start Up Mode.
Start Up Mode
During Start Up Mode, the ignition control will monitor the system for faults and begin the ignition sequence. If no faults are present, the ignition control will begin the ignition sequence by entering an 18 second waiting period. During this time the Green
LED on the ignition control will switch between Red and Green, before maintaining a Green color.
After the waiting period, the ignition control will turn on the igniter and gas valve. The igniter will remain on until a flame is sensed, or up to 10 seconds.
Once a flame has been sensed the ignition control will stop sparking, the gas valve will remain on and ignition control will enter Run Mode.
If a flame is not sensed, the ignition control will then begin two additional retrials for ignition. The ignition control will re-enter the 18 seconds waiting period before the ignition control makes another attempt at ignition. If the three attempts at ignition fail, the ignition control will enter Lockout Mode.
Run Mode
While in Run Mode the ignition control leaves the gas valve on, monitors the flame signal, and leaves the igniter off.
If a flame signal is lost during Run Mode, one additional retrial for ignition will take place within one second. The ignition control will restore the spark for approximately 10 seconds. If the ignition re-attempt fails, the ignition control will enter Lockout Mode.
The ignition control will remain in Run Mode until
24VAC is removed from terminals TH and GND on the control.
Termination of Flame
The flame will go out when power is removed from ignition control. The ignition control will turn off the gas valve and enter Standby Mode.
Lockout Mode
When Lockout Mode is entered, the ignition control will remove power to the gas valve, the igniter will turn off, the Lockout/Reset Light will turn on, and the
Diagnostic LED will display the appropriate Error
Code.
Lockout Manual Reset
Lockout Mode is cleared by pressing an external reset switch for three seconds. The ignition control will clear all error codes and enter Standby Mode. During
Lockout Manual Reset, the Diagnostic LED on the ignition control flashes red and orange, and the Reset
Light remains on until the ignition control is reset.
After the Reset Light turns off, stop pressing the switch. Holding the reset for three seconds after lockout has been cleared will cause a fault and result in entering Lockout Mode again.

System Tests
The following system tests are performed during normal operation. System tests are performed at a minimum of every 24 hours.
Low Voltage Detection
If the voltage between terminals TH and GND on the control is below 18.75VAC +/- 0.75VAC for more than
3 seconds the ignition control will turn off the gas valve and will not attempt to spark. The Diagnostic
LED will display Error Code 5. The ignition control will not enter Lockout Mode if a low voltage condition is detected, but will enter Standby Mode and wait for the low voltage condition to be cleared.
If the voltage between terminals TH and GND on the control rises above 19.75VAC +/- 0.1VAC for at least
3 seconds, the ignition control will then enter Start Up
Mode.
Low Voltage Detection test is disabled during Run
Mode.
Gas Valve
The ignition control verifies that the gas valve is connected. Failure of this test results in the ignition control entering Lockout Mode with the Diagnostic
LED displaying Error Code 2.

Maintenance
WARNING
To reduce the risk of electric shock, fire, explosion, serious injury or death:
• Disconnect electric power to the tumbler before servicing.
• Close gas shut-off valve to gas tumbler before servicing.
• Close steam valve to steam tumbler before servicing.
• Never start the tumbler with any guards/panels removed.
• Whenever ground wires are removed during servicing, these ground wires must be reconnected to ensure that the tumbler is properly grounded.
Daily
1. Inspect the area surrounding tumblers, remove all combustible materials, including lint, before operating the machines.
2. Check cylinder for foreign objects to avoid damage to clothing and equipment.
3. Clean lint from lint compartment and screen to maintain proper airflow and avoid overheating.
WARNING
To reduce the risk of serious injury, do not open the lint panel while the tumbler is in operation. Before cleaning the lint screen, open tumbler door and allow cylinder to completely stop.
W410 a. Open the lint panel.
b. Remove all accumulated lint in the lint compartment area. Lightly brush any lint that may be left on the lint screen. Lint left in the lint compartment is drawn back onto the lint screen and will restrict airflow.
c. Be sure the lint screen is not torn. If it is, replace immediately. A torn lint screen allows lint to pass from the tumbler to the ductwork system and may restrict airflow.
d. The lint screen is designed to completely cover the entire opening in the lint screen panel. Be sure that it does so. Excessive gaps between the lint screen and the lint screen panel allow lint to pass into the ductwork system and may restrict airflow.
