INTRODUCTION
ML-410 MACHINE OPERATIONAL SUMMARY
The model ML-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 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 7 MICROPROCESSOR CONTROLLER (Computer) display will
light when the EMERGENCY STOP (E-Stop) BUTTON is in the released mode. To turn ON the ML-
410s control voltage, press the green ON push-button located on the Right Front Control Door.
The ML-410 has two (2) electronic controllers:
PHASE 7 MICROPROCESSOR CONTROLLER (Computer) ... for drying material
MODICON PLC (Programmable Logic Controller) ... for loading, unloading auto doors, and burner
status monitoring
The PHASE 7 MICROPROCESSOR CONTROLLER (Computer) only response to keyboard (touchpad)
commands when the ML-410s tumbler (basket) section is level with the loading doors and lint drawer/basket
door closed. Likewise, the MODICON 1 PLC (Programmable Logic Controller) responses to load or unload
selections when the ML-410 is not drying material.
ML-410 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)
CONTROL POWER (Indicator/Control Power On Push-Button)
CONTROL POWER (Off Push-Button)
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 7 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 machine (enable the machine to run).

6
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 (basket). JOG functions are only enabled when the doors are open.
NOTE: There is a PLC 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 ML-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, machine level), an operator
will be able to select a drying cycle on the Phase 7 Microprocessor Controllers (computer) keyboard (touchpad)
located on the Right Front Control Door. Refer to the Phase 7 Operators Manual for details.
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/AIR JET
This amber colored indicator located on the top of the ML-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. TheAir 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).

ML-410 MACHINE OPERATION TROUBLESHOOTING INFORMATION
END OF CYCLE/HEATER FAULT INDICATOR
The End of Cycle light located on the top of the ML-410, is triggered by the End of Cycle Signal of the Phase 7
Microprocessor Controller (computer) I/O (input/output) board. 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.
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 (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 machine for detailed signal information
for higher level troubleshooting.
AIR JET
The Air Jet signal is sent from the Phase 7 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 [5.512 bars]).
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.
(light emitting diode) is not on it may be an indication of a failed Phase 7 Microprocessor Controller
(computer) I/O (input/output) board.

8
3. IfAir Jet L.E.D. (light emitting diode) is on then check the wiring from the Phase 7 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 machine 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 load doors only
If this selection does not operate;
1. Check that 80 PSI (5.512 bars) 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 (basket) 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.
2. Check that 80 PSI (5.512 bars) of compressed air is supplied to the machine 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 machine.
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 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).
2. Check that 80 PSI (5.512 bars) 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.

9
DRY
This selection prepares the machine for a Material Drying Command from the Phase 7 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 (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 senses that the load 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 side of the lint drawer door.
IMPORTANT: THE LINT DRAWER MUST BE CLOSED BEFORE BRINGING THE
MACHINE 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 (5.512 bars) of compressed air is supplied to the machine and that the Front Down or
Rear Down solenoid is being actuated by the PLC.
3. Verify that the Lint Drawer 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 machine.
ONE or BOTH BURNERS DO NOT IGNITE
The model MLG-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. (light emitting diode) 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. (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: BURNER 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.

10
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).
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 gas valve to measure the manifold pressure.
IMPORTANT INFORMATION
Once the Blower Motor starts, both the FRONTAIRFLOW SWITCH and the REARAIRFLOW SWITCH
must pull in to indicate that there is sufficient airflow through the machine for safe ignition of both the
Front Burner and the Rear Burner.

11
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

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.
