INTRODUCTION AD-410 DRYER OPERATIONAL SUMMARY The model AD-410 incorporates one (1) “EMERGENCY STOP” (E-Stop) BUTTON located centrally on the right front control door. This “red” mushroom push-button is “PUSH TO STOP” the dryer and “TURN TO RELEASE” or “PULL TO RELEASE” type control device. This button must be in the released mode to power the dryer. The PHASE 5 MICROPROCESSOR CONTROLLER (computer) display will light when the “EMERGENCY STOP” (E-Stop) BUTTON is in the released mode.
“EMERGENCY STOP” (E-Stop) BUTTON (Push To Stop/Turn To Release or Pull To Release) This “red” mushroom push-button, located in the center of the right front control door almost directly under the Phase 5 microprocessor controller (computer) is a “Push To Stop” and “Turn To Release” type push-button. This button must be in the released mode to power the dryer (enable the dryer to run).
CONTROL POWER (On) This “green” lighted operator, located on the right front control door, is for enabling the dryer’s control voltage. This push-button must be “ON” for drying or load/unload function to occur. CONTROL POWER (Off) This “red” non-lighted operator, located on the right front control door, is for disabling the dryer’s output control voltage. This push-button is mainly for use as a troubleshooting function.
AD-410 DRYER OPERATION TROUBLESHOOTING INFORMATION END OF CYCLE/HEATER FAULT INDICATOR The “END OF CYCLE” light located on the top/front of the AD-410, is triggered by the Air Jet Signal of the Phase 5 microprocessor controller (computer) to the input of the PLC (Programmable Logic Controller). If this signal is not sensed by the PLC the light will not turn on. The “1-second flashing” is accomplished by a “Flasher Module” located on the main control panel in the right front control cabinet.
2. Check to see that the Air Jet L.E.D. (light emitting diode) is on at the end of the drying cycle. If the L.E.D. is not on it may be an indication of a failed Phase 5 microprocessor controller (computer). 3. If Air Jet L.E.D. is on then check the wiring from the Phase 5 microprocessor controller (computer) to the air valve. 4. Faulty air valve.
2. Check that 80 PSI (5.51 bars) of compressed air is supplied to the dryer and that the “Front Up” solenoid is being actuated by the PLC (Programmable Logic Controller). Refer to the PLC signal information included in the ladder diagrams and schematics supplied with the dryer. DRY This selection prepares the dryer for a “Material Drying Command” from the Phase 5 microprocessor controller (computer).
When a “HEATER FAULT” occurs after the first 25-seconds of the drying cycle, a “CLEAR/STOP” will be sent to the Phase 5 microprocessor controller (computer), a “FILL” message will be displayed on the Phase 5 microprocessor controller’s (computer’s) display, and both the “HEATER FAULT” push-button and the “END OF CYCLE” light will flash.
Once the flame has been established in both burner boxes, the natural gas outlet manifold pressure measured at each gas valve pressure tap must be 3.5 inches W.C. (water column) - 8.7 mb - pressure. Connect a water tube manometer to the 1/8” F.P.T. gas pressure tap on the downstream side of each gas valve. There is a pressure regulator in both gas valves so the manifold pressure can be adjusted to 3.5 inches water column (8.7 mb).
ONE 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 dryer for reference to the above listed information.
The AD-410 system is divided into a number of “electrical” sections which are as follows: 1. Right Front Control Panel The RIGHT FRONT CONTROL PANEL is located in the right front control cabinet of the AD-410. This panel is the heart of the drying system, where ALL control signals interface to or from this panel. The signals that interface to this panel are too many to list here, however, they are ALL identified on TB1 of its schematic diagram. 2.
4. Optional Sprinkler Circuit The OPTIONAL SPRINKLER CIRCUIT main control panel will be located in the left front electrical enclosure. If a SPRINKLER OPTION is included with this AD-410, this panel will include an “AUTOMATIC ‘EMERGENCY STOP’ (E-Stop)” feature. This feature requires the Sprinkler Circuit be functional for the dryer to be powered. NOTE: There will be a dedicated electrical connection in the right electrical junction box for the sprinkler circuit.

Reconnect the 1/4” (6.
B. FRESH AIR SUPPLY REQUIREMENTS When the dryer is operating, it draws in room air, heats it, passes this air through the tumbler (basket) and exhausts it out of the building. Therefore, the room air must be continually replenished from the outdoors. If the make-up air is inadequate, drying time and efficiency will be adversely affected. Ignition problems and sail switch “fluttering” problems may result, as well as premature motor failure from overheating.
C. EXHAUST REQUIREMENTS NOTE: For 1 door AD-410 dryer models, the 28-inch (71.12 cm) diameter exhaust duct exits from the rear of the base. For 2 door AD-410 dryer models, the 28-inch (71.12 cm) diameter exhaust duct exits from the left hand side of the base. NOTE: For 1 door/2-way tilt AD-410 dryer models, keep the exhaust ducting at least 36-inches (91.44 cm) away from the back of the dryer so that the dryer will not hit the ducting when the dryer tilts to the rear. 1.
2) Vertical Venting IMPORTANT: Minimum duct size for a vertical run must be 32-inches (81.28 cm) for a round or 30” x 28” (76.2 cm x 71.12 cm) for a square duct. Duct size must not be reduced anywhere downstream of the dryer. THE AD-410 MUST BE INDEPENDENTLY EXHAUSTED. COMMON DUCT WORK IS NOT ACCEPTABLE. The exhaust duct should be laid out in such a way that the duct work travels as directly as possible to the outdoors with as few turns as possible.
b. Steam Models 1) Horizontal Venting THE AD-410 MUST BE INDEPENDENTLY EXHAUSTED. COMMON DUCT WORK IS NOT ACCEPTABLE. The exhaust duct should be laid out in such a way that the duct work travels as directly as possible to the outdoors with as few turns as possible. It is suggested that the use of 90° turns in ducting be avoided; use 30° and/or 45° angles instead. The shape of the exhaust duct work is not critical so long as the minimum cross section area is provided.
ALL duct work should be smooth inside with no projections from sheet metal screws or other obstructions which will collect lint. When adding ducts, the duct to be added should overlap the duct to which it is to be connected. ALL duct work joints must be taped to prevent moisture and lint from escaping into the building. Inspection doors should be installed at strategic points in the exhaust duct work for periodic inspection and clean-out of lint from the duct work.
D. COMPRESSED AIR SUPPLY SYSTEM The compressed air system of the AD-410 tilting dryer consists of a number of pneumatic pistons located throughout the dryer. The pneumatics are actuated by solenoid and flow control valves that are under computer control.
Each valve has five (5) 3/8” F.P.T. ports and two (2) electric solenoid operators, one (1) on each side of the valve. To tilt the dryer forward, a 24 volt signal is applied to the rear pistons solenoid connector “12” and no voltage is applied to the solenoid connector “14.” The internal spool in the valve will move and 80 PSI (5.51 bars) of air will enter the bottom port of the rear tilting pistons, extending the rear tilting piston rods and tilting the dryer forward for unloading.
4. OPTIONAL Automatic (Piston Operated) Load/Unload Doors If the dryer is equipped with the AUTOMATIC DOOR OPTION, then the loading doors are operated by two (2) pneumatic pistons located above the load doors. On two (2) door models, the unloading doors on the back of the dryer will also be controlled by two (2) pistons, located above the unload doors. The 24 volt solenoid valve operators controlling the door pistons are located on the pneumatic plate in the rear of the dryer’s base.

SECTION X PROCEDURE FOR FUNCTIONAL CHECK OF REPLACEMENT COMPONENTS 1. Microprocessor (computer) Board a. Upon completing installation of the replacement microprocessor (computer) board, reestablish power to the dryer. b. Start the drying cycle. c. Verify that the motor(s) and the heat indicator dots, in the microprocessor (computer) L.E.D. (light emitting diode) display are on. (Refer to the illustration below.) d.
e. Open main door. The dryer must stop and ALL indicator lights on the back side of the microprocessor (computer) board must go out. (Refer to the illustration on previous page [page 77].) f. Try to restart the dryer with the main door open. g. The microprocessor (computer) board’s L.E.D. (light emitting diode) display must read “DOOR.” h. Close the main door and restart the dryer. i. Functional check of microprocessor (computer) board is complete. 2.
3. For Direct Spark Ignition (DSI) System Models Manufactured With ADC Module Part No. 880815 a. Upon completing installation of the replacement Direct Spark Ignition (DSI) module, reestablish power to the dryer. b. Start the drying cycle. c. The ignition (DSI) module’s L.E.D. (light emitting diode) indicator will be “off” for up to approximately 1.5-seconds (prepurge time). d. The module’s indicator light will then turn “green.
SECTION XI BURNER and LINT (TUMBLER) CHAMBER MANUAL RESET HI-LIMIT INSTRUCTIONS I M P O R TA N T MANUAL RESET HI-LIMIT INSTRUCTIONS FOR GAS MODELS WITH PHASE 5 WITH HEATER FAULT This dryer was manufactured with a burner manual reset hi-limit and tumbler/lint chamber hi-limit thermostat which is monitored by the Phase 5 computer. If either manual reset thermostat is open prior to start of the drying cycle, the dryer will start momentarily and then shut down displaying a “heater fault” condition.
I M P O R TA N T MANUAL RESET HI-LIMIT INSTRUCTIONS STEAM MODELS WITH PHASE 5 This dryer was manufactured with a manual reset tumbler/lint chamber hi-limit thermostat. If the manual reset thermostat is open prior to the start of the drying cycle, or during the cycle, the dryer will not recognize the open state of the hi-limit thermostat and will start or conitnue through the drying cycle with no heat. Manual reset hi-limit must be reset manually.
