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).
