INTRODUCTION

AD-410MACHINE OPERATIONAL SUMMARY

The model AD-410incorporates one (1) “EMERGENCY STOP (E-Stop)BUTTON” located centrally on the Right Front Control Door. This "RED" MUSHROOMPUSH-BUTTONis “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 “ONpush-buttonlocated on the Right Front Control Door.

The dryer has two (2) electronic controllers:

PHASE 5 MICROPROCESSOR CONTROLLER (Computer) - for drying material

MICRO-1PLC (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-1PLC (Programmable Logic Controller) responses to load or unload selections when the dryer is not drying material.

AD-410OPERATOR 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/ReversePush-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)

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

This "red" mushroompush-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 buttonmust be in the released mode to power the machine (enable the machine to run).

JOG (Forward/ReversePush-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 aPLC (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 Drawermust 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. Thispush-buttonmust be “ON” for drying or load/unload function to occur.
