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).

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).
