Preliminary Information

About the Control

The UniLinc control on the tumble dryer is an advanced, graphical, programmable computer that lets the owner control most machine features by interacting with the control.

UniLinc allows the owner to program custom cycles, run diagnostic cycles, and retrieve audit and error information.

Tumble dryers shipped from the factory have default cycles and other settings built in. The owner can change the default cycle or any cycle.

IMPORTANT: It is extremely important that the tumble dryer has a positive ground and that all mechanical and electrical connections are made before applying power to or operating the tumble dryer.

DIP Switch Configuration

Make sure DIP switches are configured properly for the machine. Refer to Figure 2 below.

Power Failure Recovery

If a cycle is in progress when the power fails, and if the power outage lasts three or more seconds, the cycle is lost and cannot be resumed when power recovers. If the power outage lasts less than three seconds, the control will resume the cycle when the power recovers.

Communications

The control has the ability to communicate with a PDA and a laptop with an IrDA device running the UniLinc software. Devices such as PDAs and laptops that are IrDA capable (able to transmit information to machine) that have been tested and approved for use with the UniLinc software can be used as a tool for managing the machine.

The control will also accept communication with a network which allows the control to be linked to a personal computer. This network link allows an owner to program, collect data and run diagnostics on any machine. For detailed information on network communications, refer to the network instructions.

Figure 2

TMB1445R

Operation Modes

General Modes of Operation

In each mode of operation, the user may press keypads or communicate with the control to change the displayed menu.

Power-up Mode

The control enters this mode at power-up. After the control completes operation in the Power-up Mode it will enter Idle Mode. The display is blank during Power-up Mode.

Idle Mode

The control is ready for operation in Idle Mode. Control can display different menus depending on user input (keypad press, opening or closing the loading door, or PDA communication). If there is no user input for one minute, control will turn off the LCD backlight. The control will light when there is user input. If there is no user input for 10 minutes, the display will go blank.

If the control is in Idle Mode, Cycle Menu is displayed, loading and lint door closed, and the

keypad is pressed, control will enter Run Mode.

Run Mode

The Control enters Run Mode during a cycle. The Display shows machine cycle time remaining, the current cycle type, segment, temperature, and graphical indicators. Loading and lint doors are closed

during Run Mode. Press keypad to stop cycle and enter Pause Mode. Press keypad to enter

Run Diagnostic Menu. Control enters Pause Mode if loading or lint door opens. Press to Rapid

Advance.

Rapid Advance Mode

If the Rapid Advance Option is enabled, the user can advance a running machine cycle by pressing the

keypad. In a Time Dry cycle, pressing the

keypad will decrease the remaining time by one minute. Pressing and holding the keypad will

decrease the remaining time by four minutes per second until the end of the cycle.

In the Cool Down segment, pressing the keypad will decrease the remaining time by one minute.

When the cycle is completed, the audit counter, Total Rapid Advance Cycles is incremented rather than the Total Machine Cycles audit counter. In addition this cycle is recorded in the audit list “Last 25 Machine Cycles Completed”. If the Rapid Advance Option is disabled preventing a manual Rapid Advance, the user may still execute a Rapid Advance using the PDA or PC. Refer to UniLinc PC and PDA Application User Instructions for additional information on using a PDA or PC to Rapid Advance a cycle.

Cycle Menu

There are 41 machine cycles that can be selected and run. Machine cycles can be modified or made “unavailable” by manually editing them in Modify Cycle Menu or by using the PDA or network to download a modified machine cycle into the control. Machine cycles cannot be deleted, but can be made “unavailable” so that they are not visible from the Cycle Menu. New machine cycles cannot be created, but existing machine cycles that have been edited to be “unavailable” may be re-edited to be available again.

Machine Cycle Operation

When a cycle is run, the control runs the cycle segment by segment in a sequence. First the control examines the Cycle Type chosen to determine if it is a Time Dry, Auto-Dry or Moisture Dry (if equipped) cycle type. Then the first segment is examined to see if it is programmed to “On” or “Off”. If the segment is programmed to “Off”, control skips to the next segment.

At the start of some machine cycles, the control displays a Total Remaining Cycle time. This time is taken from the machine cycles as they are programmed. The Total Remaining Cycle Time begins to count down as soon as the cycle is started.

Rotation Sensor Equipped Machines

On machines equipped with a rotation sensor, the control monitors the rotation sensor to verify the cylinder is rotating. The control calculates the cylinder’s RPM. If the RPM drops to zero while the cylinder is supposed to be rotating, the control will advance to the Cool Down segment of the cycle and an error message will be displayed.

Cycle Menu

Time Dry Cycle

In this type of cycle, the control will regulate the temperature and time duration as programmed for the cycle chosen.

Auto-Dry Cycle

If this type of cycle is selected, the control determines the cycle time based on the temperature and dryness level programmed for the cycle chosen.

Moisture Dry Cycle (if equipped)

In this type of cycle, the control checks the programmed material type, programmed target moisture content, programmed temperature and the data received from the moisture sensing system to achieve the desire results.
