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. To turn “ON” the AD-410’s control voltage,
press the “green” “ON” push-button located on the right front control door.

The AD-410 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 keyboard (touchpad)
commands when the AD-410’s tumbler (basket) 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 AD-410 is not drying material.

AD-410 OPERATOR CONTROLS/INDICATORS

The right front control door incorporates the following operator controls/indicators:

“EMERGENCY STOP” (E-Stop) BUTTON (Push To Stop/Turn To Release or Pull To Release)

JOG (Forward/Reverse Push-Buttons)

LOAD/DRY/UNLOAD (Three [3] Position Selector Switch)

TILT (Off - On) (Two [2] Position Selector Switch)

HEATER FAULT (Indicator/Reset Push-Button) Gas Models Only

CONTROL POWER (On)

CONTROL POWER (Off)

END OF CYCLE/HEATER FAULT INDICATOR/AIR JET

6

“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).

JOG (Forward/Reverse Push-Buttons)

These two (2) push-buttons, located towards the left hand side of the right front control door, are for either loading
or unloading the tumbler (basket). “JOG” functions are only enabled when the tumbler (basket) 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 (basket) 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 (basket) in the level position.

NOTE: The AD-410 “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 (basket) section towards the front (Rear Up). Likewise, a “LOAD” selection will open the front
horizontal doors and tilt the tumbler (basket) section towards the rear (Front Up).

The “DRY” selection will bring the tumbler (basket) 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, dryer level), an operator will
be able to select a drying cycle on the Phase 5 microprocessor controller’s (computer’s) keyboard (touchpad),
located on the right front control door. Refer to the Phase 5 Operator’s Manual for details.

HEATER FAULT (Indicator/Reset Button) Gas Models Only

During a drying cycle the PLC monitors the status of the Phase 5 microprocessor controller’s (computer’s) “Heat
On/Off” signal, the control status of the front and rear gas valves, and the state of both the front and rear burner
airflow 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 button. For more details on “HEATER FAULT” refer to the AD-410 operation section in this
manual.

7

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.

END OF CYCLE/HEATER FAULT INDICATOR/AIR JET

This “amber” colored indicator located on the front/top of the AD-410 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 - DRY - LOAD” 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 Button” located on the right front
control door. Refer to the “HEATER FAULT Indicator/Reset 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 30-seconds to remove lint which may have
accumulated on the Blower Wheel (squirrel cage).

8

AD-410 DRYER OPERA TION TROUBLESHOOTING INFORMATION

END OF CYCLE/HEATER FAUL T 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. Refer to the electrical blueprints
included with this dryer for detailed signal routing.

The “HEATER FAULT” signal is an output of the PLC 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 dryer 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 7-second dwell (delay) time between a selection of a different rotation direction. This delay is to prevent
plug starting the tumbler (basket) 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 (basket) 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 dryer for detailed signal information for
higher level troubleshooting.

AIR JET

The Air Jet signal is sent from the Phase 5 microprocessor controller (computer) at the end of the drying cycle. If
the air valve fails to operate:

1. Check the air supply to the dryer (set to 80 PSI [5.51 bars]).

9

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.

LOAD/DRY/UNLOAD (Selector Switch) and TILT FUNCTION (Off - On Selector Switch)

As mentioned in the dryer summary (refer to page 5), 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 (5.51 bars) of compressed air is supplied to the dryer 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 dryer.

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 dryer. Once the tumbler (basket) section releases the tilt switch, the “JOG”
functions become enabled for an operator’s selection.

If the tumbler (basket) section does not tilt forward:

1. Verify that a “Door Open” signal is being sensed by the PLC.

2. Check that 80 PSI (5.51 bars) of compressed air is supplied to the dryer and that the “Rear Up” solenoid is

being actuated by the PLC.

Refer to the PLC signal information included in the ladder diagrams and schematics supplied with the dryer.

LOAD TILTED

This selection causes the front horizontal doors to open. Once the “Door Open” signal is sensed, the PLC enables
the “Front Up” solenoid to tilt the dryer. The “JOG” functions then becomes enabled for an operator’s selection.

If the tumbler (basket) section does not tilt towards the rear:

1. Verify that a “Door Open” signal is being sensed by the PLC.

10

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).

NOTE: Before a drying cycle can be selected, the tumbler (basket) section must be in the level

position and both the front horizontal doors as well as the lint drawer must be closed.

The PLC senses that the dryer is level by the two (2) level switches located on the left hand side of the base section.
One (1) switch is towards the rear of the dryer and the other switch is towards the front of the dryer.

The PLC 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 senses the lint drawer by a push type switch located on the right hand side of the lint drawer door.

IMPORTANT: THE LINT DRAWER and LINT DRAWER GUARD MUST BE CLOSED

BEFORE BRINGING THE DRYER TO A LEVEL POSITION.

If the tumbler (basket) section does not return to a level position:

1. Verify that a “Door Closed” signal is being sensed by the PLC.

2. Check that 80 PSI (5.51 bars) of compressed air is supplied to the dryer and that the “Front Down” or “Rear
Down” solenoid is being actuated by the PLC.

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 input.

Refer to the PLC signal information included in the ladder diagrams and schematics supplied with the dryer.

HEATER FAULT (Indicator/Reset Push-Button) Gas Dryers Only

“HEATER FAULT” refers to a problem in the gas heating portion of the dryer.

The PLC 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 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” push­button and the “END OF CYCLE” light will flash.

11

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.

NOTE: If the “HEATER FAULT” reset push-button is pressed any time during the PLC

(Programmable Logic Controller) controlled cool down cycle, the dryer will come to a
stop since the dryer is being attended to by a qualified operator.

“HEATER FAULT” occurs during the following conditions:

Front and/or rear or both airflow switches are in the closed position at the start of a drying cycle.

IMPORTANT: At the start of a drying cycle, the tumbler (basket) will begin to turn and a few

seconds thereafter, the “FAN” signal will be asserted.

IF BOTH AIRFLOW 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 dryer will come to a
complete halt/stop until the “HEATER FAULT” push-button is pressed.

ONE or BOTH BURNERS DO NOT IGNITE

The model ADG-410 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 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 “LOCKOUT” mode lighting the
L.E.D. 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 dryer, 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 (14.92 mb) and 12 inches of W.C. (water
column) - 29.9 mb - pressure. If the supply pressure is above 12 inches water column (29.9 mb) than an external
regulator must be installed to reduce the gas supply pressure to between 6 inches (14.92 mb) and 12 inches of
water column (29.9 mb).

12

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).
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).

The L.P. (liquid propane) gas pressure measured at each gas valve pressure tap must be 11 inches water column
(27.4 mb) 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 11 inch water
column (27.4 mb) outlet manifold pressure. Connect a water tube manometer to the 1/8” F.P.T. gas pressure tap
on the downstream side of each valve to measure the manifold pressure.

IMPORTANT INFORMATION

Once the blower motor starts, both the FRONT AIRFLOW SWITCH and the REAR AIRFLOW SWITCH
must pull in to indicate that there is sufficient airflow through the dryer 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 AIRFLOW SWITCH

REAR AIRFLOW SWITCH
EXHAUST HI-LIMIT SWITCH
FRONT BURNER INTAKE HI-LIMIT SWITCH
REAR BURNER INTAKE HI-LIMIT SWITCH
DEFECTIVE ELECTRICAL HEAT CIRCUIT

13

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.

ONE 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 dryer 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 dryer.
This push-button indicator must be “ON” for the system to load or dry material.

Refer to the ladder diagram included with this AD-410 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 dryer.

Refer to the ladder diagram included with this AD-410 for the function of this push-button in the 24 VAC control
voltage latching control circuit.

SYSTEM LADDER DIAGRAM

The SYSTEM LADDER DIAGRAM is an overview on the electrical connections of the AD-410. This diagram
is for signal flow information and is a tool to direct an individual in the correct direction for troubleshooting this
dryer.

14

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. Right Base Electrical Enclosure

The RIGHT BASE ELECTRICAL ENCLOSURE is located towards the front of the right base section. An
industrial multi-pin connector is used to connect the base section control signals to the tumbler (basket)
section’s main control panel. This electrical enclosure is labeled CAUTION, HIGH VOLTAGE IS
PRESENT IN THIS ENCLOSURE and incorporates the following electrical devices:

The MAIN ELECTRICAL POWER to the dryer

The ELECTRICAL CONNECTION for the “OPTIONAL” SPRINKLER CIRCUIT POWER

The THERMAL/MAGNETIC OVERLOAD and REVERSING CONTACTOR for the TUMBLER
(BASKET) MOTOR

The THERMAL/MAGNETIC OVERLOAD and REVERSING CONTACTOR for the BLOWER
MOTOR

3. Right Base Interface Junction Box

The RIGHT BASE INTERFACE JUNCTION BOX is located towards the rear of the right base section and
is used as a central location to interface the base section electrical components to the TILTING tumbler
(basket) section. An industrial multi-pin connector is used to connect the base section control signals to the
tumbler (basket) section’s main control panel. The control signals incorporated in the right base interface
junction box are:

SOLENOID CONTROL

Front Up/Front Down
Rear Up/Rear Down
Open Front Door
Supply Air Enable
Air Jet

LINT DRAWER/GUARD STATUS

TUMBLER (BASKET) TEMPERATURE and HI-LIMIT INFORMATION

TUMBLER (BASKET) LEVEL SENSE

Front Level Switch
Rear Level Switch

OPTIONAL SPRINKLER CONTROL SIGNALS

15

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.

IMPORTANT INFORMATION

A. RECEIVING and HANDLING

The dryer is shipped in a protective stretch wrap cover with protective cardboard corners and top cover (or
optional box) as a means of preventing damage in transit. Upon delivery, the dryer and/or packaging, and wooden
skid should be visually inspected for shipping damage. If any damage whatsoever is noticed, inspect further
before delivering carrier leaves.

Dryers damaged in shipment:

1. ALL dryers should be inspected upon receipt and before they are signed for.

2. If there is suspected damage or actual damage, the trucker’s receipt should be so noted.

3. If the dryer is damaged beyond repair, it should be refused. Those dryers which were not damaged in a
damaged shipment should be accepted, but the number received and the number refused must be noted on
the receipt.

4. If you determine that the dryer was damaged after the trucker has left your location, you should call the
delivering carrier’s freight terminal immediately and file a claim. The freight company considers this concealed
damage. This type of freight claim is very difficult to get paid and becomes extremely difficult when more
than a day or two passes after the freight was delivered. It is your responsibility to file freight claims. Dryer/
parts damaged in transit cannot be claimed under warranty.

5. Freight claims are the responsibility of the consignee, and ALL claims must be filed at the receiving end.
ADC assumes no responsibility for freight claims or damages.

6. If you need assistance in handling the situation, please contact the ADC Traffic Manager at (508)
678-9000.

IMPORTANT: The dryer must be transported and handled in an upright position at ALL times.
