INTRODUCTION
AD-310 MACHINE OPERATIONAL SUMMARY
The model AD-310 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 machine and “TURN TO RELEASE” or “PULL TO RELEASE” type control device. This button must be in the released mode to power the machine. The PHASE 5 MICROPROCESSOR CONTROLLER (Computer) display will light when the “EMERGENCY STOP (E-Stop) BUTTON” is in the released mode. To turn “ON” the control voltage, press the green “ON” push-button located on the Right Front Control Door.
The dryer has two (2) electronic controllers:
PHASE 5 MICROPROCESSOR CONTROLLER (Computer) - for drying material
MICRO-1 PLC (Programmable Logic Controller) - for loading, unloading auto doors, and burner status monitoring
The Phase 5 Microprocessor Controller (computer) only response to keypad (touchpad) commands when the tumbler section is level with the loading doors and lint drawer/basket door closed. Likewise, the Micro-1 PLC (Programmable Logic Controller) responses to load or unload selections when the dryer is not drying material.
AD-310 OPERATOR CONTROLS/INDICATORS
The Right Front Control Door incorporates the following operator controls/indicators: EMERGENCY STOP (E-Stop) BUTTON (Push To Stop/Turn or Pull To Release) JOG (Forward/Reverse Push-Buttons)
UNLOAD/DRY / LOAD (Selector Switch)
TILT FUNCTION (Off - On Selector Switch)
HEATER FAULT (Indicator/Reset Push-Button)
CONTROL POWER (Indicator/Control Power On Push-Button)
CONTROL POWER (Off Push-Button)
5
EMERGENCY (E-Stop) 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 pushbutton. This button must be in the released mode to power the machine (enable the machine to run).
JOG (Forward/Reverse Push-Buttons)
These two (2) push-buttons, located towards the left side of the Right Front Control Door, are for either loading or unloading the tumbler. “JOG” functions are only enabled when the tumbler section is in a tilted position.
NOTE: There is a PLC (Programmable Logic Controller) controlled “DWELL TIME” between forward jog or reverse jog selection to prevent plug starting the tumbler drive motor.
LOAD / DRY / UNLOAD (Three [3] Position Selector Switch)
TILT (Off - On) (Two [2] Position Selector Switch)
The “LOAD / DRY / UNLOAD” and “TILT (Off - On)” selector switches work in conjunction with each other. If the “TILT” selector is in the “OFF” position, an “UNLOAD" or “LOAD” selection will open the front horizontal doors, allowing an operator to load or unload the tumbler in the level position.
NOTE: The “JOG” feature will respond in the level position. The Lint Drawer must be closed for the “JOG” feature to operate.
If the “TILT” selector is in the “ON” position, an “UNLOAD” selection will open the front vertical doors and tilt the tumbler section towards the front (Rear Up). Likewise, a “LOAD” selection will the front horizontal doors and tilt the tumbler section towards the rear (Front Up).
The “DRY” selection will bring the tumbler section to a level position and close the front horizontal doors. Once ALL safe conditions are met (i.e., front doors closed, lint drawer closed, machine level), an operator will be able to select a drying cycle on the Phase 5 Microprocessor Controller’s (computer) keypad (touchpad), located on the Right Front Control Door. Refer to the Phase 5 Operator’s manual for details.
HEATER FAULT (Indicator/Reset Button) for GAS MODELS ONLY
During a drying cycle the PLC (Programmable Logic Controller) monitors the status of the Phase 5 Microprocessor Controller’s (computer) “Heat On/Off” signal, the control status of the front and rear gas valves, and the state of both the front and rear burner air flow switches. If a fault is sensed, the "HEATER FAULT" indicator and “END OF CYCLE" indicator will begin to flash at a rate of one (1) per second. Both indicators will flash until the operator presses the “HEATER FAULT" reset push-button. For more details on “HEATER FAULT” refer to the operation section in this manual.
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.
6
CONTROL POWER (Off)
This "RED 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.
END OF CYCLE / HEATER FAULT INDICATOR / AIR JET
This amber colored indicator located on the front/top of the dryer has two (2) functions:
1.To indicate that a drying cycle has been completed and that the dried material is ready for attention. Once the dryer is attended (i.e., lint drawer is opened, or the “UNLOAD - DRYLOAD” selector is turned to either the “UNLOAD” or “LOAD” position and the vertical doors open) the indicator will go off.
2.To indicate that a “HEATER FAULT” has occurred.
Note that during a “HEATER FAULT” this indicator will flash in conjunction with the “HEATER FAULT" indicator/reset push-button” located on the Right Front Control Door. Refer to the “HEATER FAULT" Indicator/Reset Push-Button explanation on the previous page (page 6), for more information concerning “HEATER FAULTS.”
3.The Air Jet will be activated at the end of the drying cycle when the “END OF CYCLE “light has been energized. The Air Jet will remain active for approximately thirty (30) seconds to remove lint which may have accumulated on the Blower Wheel (squirrel cage).
7
AD-310 MACHINE OPERATION TROUBLESHOOTING INFORMATION
END OF CYCLE/HEATER FAULT INDICATOR
The “END OF CYCLE” light located on the top/front of the dryer, 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. Refer to the electrical blueprints included with this machine for detailed signal routing.
The “HEATER FAULT” signal is an output of the PLC (Programmable Logic Controller) to the “END OF CYCLE” light. A “HEATER FAULT” is an indication that a malfunction has occurred in the “Gas Heat Circuit” and needs attention. Refer to the “HEATER FAULT” explanations on page 10 and page 11 for more information on this subject.
If this “END OF CYCLE" light fails to display at the end of every cycle;
1.Check the bulb.
2.Check voltage to the bulb (24 VAC).
3.Refer to the ladder diagram and the schematics provided with this machine for detailed signal information for higher level troubleshooting.
JOG (Forward / Reverse Push-Button)
Forward “JOG” is in the clockwise (CW) direction and Reverse “JOG” is in the counterclockwise (CCW) direction.
There is a seven (7) second dwell (delay) time between a selection of a different rotation direction. This delay is to prevent plug starting the tumbler drive motor.
If the “JOG” function does not operate in the tilted position;
1.Check that the Main Doors are fully opened.
2.Check that the Overload for the Drive Motor is in the “Start” position.
3.Check that the Overload for the Tumbler Motor is in the “Start” position.
4.Check that the Lint Drawer is closed.
5.Refer to the ladder diagram and the schematics provided with this machine for detailed signal information for higher level troubleshooting.
AIR JET
If this selection does not operate;
1. Check the air supply to the dryer (set at 80 PSI).
8
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.Bad air valve.
LOAD / DRY / UNLOAD (Selector Switch) and TILT FUNCTION (Off - On Selector Switch)
As mentioned in the machine summary (refer to page 6), the “LOAD / DRY / UNLOAD” selector switch and “TILT Off - On” selector switch work in conjunction with each other.
UNLOAD or LOAD LEVEL...opens the Vertical Doors ONLY
If this selection does not operate;
1.Check that 80 PSI of compressed air is supplied to the machine and that the door solenoid is being actuated. The “Door Open” signal is generated by the PLC (Programmable Logic Controller). Refer to the PLC information included in the ladder diagrams and schematics supplied with the machine.
UNLOAD TILTED
This selection causes the front horizontal doors to open. Once the “Door Open” signal is sensed, the PLC enables the “Rear Up” solenoid to tilt the machine. Once the tumbler section releases the tilt switch, the “JOG” functions become enabled for an operator’s selection.
If the tumbler section does not tilt forward;
1.Verify that a “Door Open” signal is being sensed by the PLC (Programmable Logic Controller).
2.Check that 80 PSI of compressed air is supplied to the machine and that the “Rear Up” solenoid is being actuated by the PLC (Programmable Logic Controller).
Refer to the PLC (Programmable Logic Controller) signal information included in the ladder diagrams and schematics supplied with the machine.
LOAD TILTED
This selection causes the front horizontal doors to open. Once the “Door Open” signal is sensed, the PLC (Programmable Logic Controller). enables the “Front Up” solenoid to tilt the machine. The “JOG” functions then becomes enabled for an operator’s selection.
If the tumbler section does not tilt towards the rear;
1. Verify that a “Door Open” signal is being sensed by the PLC (Programmable Logic Controller).
9
2.Check that 80 PSI of compressed air is supplied to the machine and that the “Front Up” solenoid is being actuated by the PLC (Programmable Logic Controller).
Refer to the PLC (Programmable Logic Controller) signal information included in the ladder diagrams and schematics supplied with the machine.
DRY
This selection prepares the machine for a “Material Drying Command” from the Phase 5 Microprocessor Controller (computer).
NOTE: Before a drying cycle can be selected, the tumbler section must be in the level position and both the Front Horizontal Doors as well as the Lint Drawer must be closed.
The PLC (Programmable Logic Controller) senses that the machine is level by the two (2) level switches located on the left side of the base section. One (1) switch is towards the rear of the machine and the other switch is towards the front of the machine.
The PLC (Programmable Logic Controller) senses that the vertical doors are closed by the two (2) proximity switches located at the top center, of the dryer above the doors. These switches are magnetically actuated by magnets located on the doors.
The PLC (Programmable Logic Controller) senses the Lint Drawer by a push type switch located on the right side of the lint drawer door.
IMPORTANT: THE LINT DRAWER and LINT DRAWER GUARD MUST BE CLOSED BEFORE BRINGING THE MACHINE TO A LEVEL POSITION.
If the tumbler section does not return to a level position;
1.Verify that a “Door Closed” signal is being sensed by the PLC (Programmable Logic Controller).
2.Check that 80 PSI of compressed air is supplied to the machine and that the “Front Down” or “Rear Down” solenoid is being actuated by the PLC (Programmable Logic Controller).
3.Verify that the Lint Drawer and Lint Drawer Guard is in the closed position. This signal can be easily verified since it is a PLC (Programmable Logic Controller) input.
Refer to the PLC (Programmable Logic Controller) signal information included in the ladder diagrams and schematics supplied with the machine.
HEATER FAULT (Indicator/Reset Push-Button) for GAS MODELS ONLY
“HEATER FAULT” refers to a problem in the Gas Heating portion of the machine.
The PLC (Programmable Logic Controller) monitors the Phase 5 Microprocessor Controller’s (computer’s) Heat Off/On signals to the two (2) individual gas valves that supply the two (2) separate burners.
When a “HEATER FAULT” occurs within the first twenty-five (25) seconds of the drying cycle, the dryer will go to a “FILL” message on the Phase 5 Microprocessor Controller’s (computer’s) display and both the “HEATER FAULT" reset push-button and the “END OF CYCLE" light will flash.
1 0
When a “HEATER FAULT” occurs after the first twenty-five (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” reset pushbutton and the “END OF CYCLE" light will flash.
NOTE: If the “HEATER FAULT Reset Push-Button” is pressed any time during the PLC (Programmable Logic Controller) controlled cool down cycle, the machine will come to a stop since the machine is being attended to by a qualified operator.
“HEATER FAULT” occurs during the following conditions:
Front and/or rear or both air flow switches are in the closed position at the start of a drying cycle.
IMPORTANT: At the start of a drying cycle, the tumbler will begin to turn and a few seconds thereafter, the “FAN “ signal will be asserted.
IF BOTH AIR FLOW SWITCHES ARE NOT OPEN AT THIS TIME THE
BLOWER WILL NOT START and A “HEATER FAULT” WILL OCCUR.
Both HEATER FAULT Indicators” will flash and the machine will come to a complete halt/stop until the “HEATER FAULT" reset push-button is pressed.
ONE or BOTH BURNERS DO NOT IGNITE
The dryer has two (2) burner boxes. Each burner box has its own Gas Valve, Spark Ignitor/Flame-Probe Assembly, and DSI (Direct Spark Ignition) Module.
DSI (Direct Spark Ignition) Module
When the dryer calls for heat, and ALL dryer safety switches are satisfied, a 24 VAC control signal is supplied to both DSI (Direct Spark Ignition) Modules. The DSI Module L.E.D. (light emitting diode) indicators will light “red” for approximately 1.5-seconds of pre-purge, the L.E.D. indicators will light “green”. Each DSI Module will energize its’respective gas valve and provide an 8-second spark to its’Spark Ignitor/Flame-Probe Assembly. The gas in both burner boxes should ignite. If ignition does not occur in one or both burners after 8-seconds, the flame will not be sensed by the Spark Ignitor/Flame-Probe Assembly and the DSI Module will go into the “LOCK-OUT” mode lighting the L.E.D. (light emitting diode) indicator(s) “red” continuously. THERE ARE NO IGNITION RETRIES BY THE DSI MODULE. Stop the dryer at this point and restart another drying cycle. It may take several restarts to clear the gas supply piping of air.
NOTE: “HEATER FAULT” will occur during the initial set up of the machine, indicating that the burners are not lighting due to air in the gas line.
GAS PRESSURE
The natural gas pressure supplied to the dryer must be between 6-inches and 12-inches of W.C. (water column) pressure. If the supply pressure is above 12-inches water column than an external regulator must be installed to reduce the gas supply pressure to between 6-inches and 12-inches of water column.
1 1
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 3-1/2 inches W.C. (water column) 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 3-1/2” water column (W.C.). Unscrew the slotted regulator cover which is located on the top of each gas valve, and turn the regulator adjustment screw located underneath the cover (clockwise [CW] to increase manifold pressure and counterclockwise [CCW] to decrease manifold pressure).
MAN2633
The L.P. (liquid propane) gas pressure measured at each gas valve pressure tap must be 11-inches water column (W.C.) pressure, when the flame is established in both burner boxes. There is no means to adjust this pressure supplied with the dryer so the downstream L.P. pressure regulator must be adjusted to provide the 11inch water column (W.C.) outlet manifold pressure. Connect a water tube manometer to the 1/8” F.P.T. gas pressure tap on the downstream side of each gas valve to measure the manifold pressure.
IMPORTANT INFORMATION
Once the Blower Motor starts, both the FRONT AIR FLOW SWITCH and the REAR AIR FLOW SWITCH must pull in to indicate that there is sufficient air flow through the machine for safe ignition of both the Front Burner and the Rear Burner.
Refer to the system ladder diagram for “HEAT” signal information. There are several safety devices that must be satisfied prior to ignition. Any one of these safety devices can cause NO IGNITION, therefore a “HEAT FAULT”...i.e., FRONT AIR FLOW SWITCH
REAR AIR FLOW SWITCH EXHAUST HI-LIMIT SWITCH
FRONT BURNER INTAKE HI-LIMIT SWITCH
REAR BURNER INTAKE HI-LIMIT SWITCH

SECTION II
ROUTINE MAINTENANCE
A. CLEANING
A schedule should be established for periodic inspection, cleaning, and removal of lint from various areas of the dryer, as well as throughout the duct work system. The frequency of cleaning can best be determined from experience at each location. Maximum operating efficiency is dependent upon proper air circulation. The accumulation of lint can restrict this air flow. If the guidelines in this section are met, an ADC dryer will provide many years of efficient, trouble-free, and - most importantly - safe operation.
WARNING: LINT FROM MOST FABRICS IS HIGHLY COMBUSTIBLE. THE ACCUMULATION OF LINT CAN CREATE APOTENTIAL FIRE HAZARD.
WARNING: KEEP DRYER AREA CLEAR AND FREE FROM COMBUSTIBLE MATERIALS, GASOLINE, and OTHER FLAMMABLE VAPORS and LIQUIDS.
NOTE: REMOVE POWER FROM THE MACHINE BEFORE PERFORMING ANY MAINTENANCE IN THE MACHINE.
