Program Operation
To Start: (after power on to unit)

TEMP Display
For fill steps and temperature controlled steps (thermal fill):

• Pressing both TEMP keys . . . displays programmed set temperature (thermal fill steps only).

TIME Display
Total program time is normally displayed. While a program is running:

• Press TIME up and down keys to change step time (and overall program time). Only available in Program and Run2 modes.
• Pressing both TIME keys displays the step time remaining, and flashes the step display.
• For fill steps and temperature controlled steps (thermal fill), pressing both TIME keys displays the time step has been running.

To exit the wash cadence programming mode:
Press Select Key once more after the REV LED is flashing.

A different wash cadence can be selected for each step.

• The default wash cadence is 26 (forward); 4 (pause); 26 (reverse); 4 (pause).
• The minimum pause time is 3 seconds.
• The maximum forward/reverse rotation time is 99 seconds.

DRAIN
Press the DRAIN key . . . turns LED on or off.

When the LED is on . . . the drain valve is open.

The valve will automatically open when the machine is in an extract step, is not operating or when power to the unit is removed.

The drain cannot be:

• closed during an extract step or,
• opened during: water/supply injection or, heat control or, Polycool.

If the DRAIN LED is on and OPTIONS -Water Reuse- is selected, the unit will drain to the water reuse tank (see Water Reuse in the OPITIONS section).

HOT AND COLD WATER
There are two methods to fill the wash tub with water:

1. Non-temperature control fill; and
2. Thermal fill (fill to temperature).

Non-Temperature Control Fill
For non-temperature control operation the hot and cold inject valves follow the status of the HOT and COLD LED’s.

1. Pressing the HOT and COLD keys toggle the status of the LED’s. The valves are independently programmable, and are disabled during any extract step.

Temperature Control Fill (Thermal fill)

For filling the wash tub to a specific pre-set temperature.

1. Temperature control injection can be enabled only when both the HOT and COLD LED’s are turned on.
2. To enable the temperature control: Press the TEMP up or down arrow key to set controlled temperature.

If temperature control is enabled and the unit is running:

• The hot and cold valves will open and close to regulate to the temperature . . .
• HOT and COLD LED’s will be on
• The blinking LED indicates which valve is open.

If a FILL level is also selected for the step, the unit will attempt to control the temperature until the fill level is reached.

If a FILL level and TIME are not selected for the step, the unit will attempt to control the temperature:

• until the temperature is reached, or
• until an overflow fill level is reached or
• until a time-out of 30 minutes.

If a TIME is entered for the step, the unit will:

• regulate for that period of time or
• until an overflow fill level is reached.

The temperature band for valve operation is +/- 5 oF to prevent "chatter" of valves.
The set temperature range is 45 to 205 oF.

CHEMICAL Supplies
The CHEMICAL supply injection:

• can only be selected during programming mode . . .
• and can only inject during a wash step without a FILL level.

Select chemicals to be injected as follows:

1. Press CHEMICALS Select Key . . . all chemical LED’s turn off - Liquid/Dry Supplies 1 LED will blink.
2. Pressing the Inject Key toggles this supply on or off. If the Inject LED is on the chemical is selected. The TIME display indicates the length of the signal in seconds. Program a time between 1 and 99 seconds. The default time is 60 seconds.
3. Press the Select Key again - only the liquid/dry supply 2 LED blinks . . . This can be selected or de-selected using the Inject Key.
4. Pressing the Select Key advances selection of all chemicals. After the last chemical status is selected, all the chemical LED’s selected for the step will be on.

When programmed into a step, supplies signals will fire the corresponding supply number for the length of time programmed from the start of the step and then automatically turn off.

• Pressing the FILL Select Keys toggles through the 5 fill levels.
• The fill level LED that is on corresponds to the desired fill level.
• If the fill level is not reached in 15 minutes a time-out error occurs.

EXTRACT
Press the EXTRACT Select key to select the extract speed. There are 2 extract speeds available. Only the LED’s corresponding to the speeds available will turn on during EXTRACT select. The following occurs during the start of an extract step:

1. The wash motor is deactivated and the distribution motor is enabled for 60 seconds. The drain is opened.
2. The distribution motor is deactivated and the low extract motor is enabled for 30 seconds.
3. The low extract motor is deactivated and the set extract speed for the step motor is activated.
4. After time out of extract step, there is a one-minute break delay.

HEAT Control
Pressing the Heat Key to turn on the Heat LED and enables heat control.

• The hot and cold LED’s must be off to enable heat control.
• The heat control valve will not turn on if there is less than the low level of water.
• Heat control cannot be enabled during an extract step.

A set temperature must be entered for heat control.

The step will end when:

• temperature is reached or
• until a 30 minute time-out occurs.

POLYCOOL
Pressing the OPTIONS Polycool key toggles the Polycool function.

1. When the Polycool LED is on, the temperature will display a set temperature.
2. The TEMP up and down arrow keys are used to set the Polycool temperature.
3. The Polycool valve will remain open until the drum temperature is less than or equal to the set temperature.

The high water level error is ignored when the Polycool function is invoked.
The drain cannot be open when the Polycool function is activated.
Polycool cannot be activated during a fill or an extract step.

When running a program, the Polycool step is complete when:

• temperature is reached or . . .
• until a 30 minute time-out error occurs.

WATER REUSE (Extra Drain and Extra Water Inlet)
Selecting OPTIONS - Water Reuse - without the Drain selected, fills the drum from the water reuse tank. Selecting OPTIONS - Water Reuse - with the Drain selected, drains to the water reuse tank.

The key sequence for programming Water Reuse is as follows:

• To program Water Reuse inlet - press Drain key, Water Reuse, Fill Select (water level). The Drain LED will turn off after the Fill Select is selected.
• To program Water Reuse drain - press Drain key, Water Reuse.

When filling the drum from the Water Reuse tank, if water level is not reached after 10 minutes, cold water is automatically injected.

DOOR LOCK
The door lock is automatically released at the end or termination of a program. The lock remains released for 20 seconds or until the door is opened. At this point, to open the door again, press the STOP/PAUSE button - the door lock will open for another 20 seconds.

When the door LED is:

• OFF - the door is closed.
• ON - the door is open.
• BLINKING - a request has been made to open the door but one or more of the following conditions has not occurred:

1. Temperature in machine is greater than 130 oF.
2. Level of water in machine more than 1 inch.

For safety, manual operation cannot be enabled and a program will not be allowed to start if the door is open. All machine operations (except for Fwd/Rev Jog on three pocket models) are prohibited when the door is opened.

BRAKE
The brake relay is activated for 1 minute after an extract function has been executed. While the brake function is active the motor(s) will not rotate. If a wash or extract function is selected the WASH or EXTRACT LED’s will blink to indicate that the brake action is in effect. When the brake is completed the motor will be allowed to rotate. For safety, if power is removed during a brake cycle the brake time will continue when power is resumed.

VIBRATION FAULT SEQUENCE
The vibration switch is not sensed until the motor is running an extract speed. If the switch is tripped at this point, the unit will execute the vibration recovery sequence. While the switch is tripped:

• an alarm will sound . . .
• an error will be displayed indicating the switch is still tripped.
• pressing the reset button (located on the machine) will remove the error.

The vibration recovery sequence is as follows:

1. The TEMP display will flash "BAL" for balance during the entire sequence.
2. The brake timer is activated . . . TIME display counts down 60 seconds for braking.
3. When the brake time is complete, the wash cadence is activated.
4. Distribution will run for 30 seconds. TIME display will count down.
5. When the distribution function is complete, the motor will resume extract speed, and the entire extract step will be repeated.

The fault recovery sequence will be executed a maximum of three times.

After three executions:

• the program or extract step is terminated,
• an alarm sounds, and an error is displayed.

What is a Program?
A program is the assembling of a series of logically ordered steps.
There are a total of 39 programs. The are configured as follows:

• 30 empty programs;
• 8 factory programs which can be edited; and
• 1 test program.

What is a Step?
A step controls a specific machine operation. For example, a fill step would allow for hot and cold water injection into the machine to either a level or temperature while rotating the basket.

There are a total of 24 steps per program. (In the ES version of the software code, total program steps is increased from 24 to 48 and total number of programs is decreased from 39 to 19.)

1. Press and hold both PROG keys until a beep sounds to delete the entire program.

The CONFIGURATION allows for viewing and setting specific control parameters. With the diagnostics jumper removed, powering on the unit while holding the START key sets the unit for configuration mode.

1. The TIME display will read "FL" and the TEMP display will read the pressure sensor a/d (analog / digital) counts. Pressing the FILL Select Key toggles through the FILL levels. The pressure a/d counts can be entered in for each fill level by using the TEMP display’s up and down arrows keys to set desired water levels. When all FILL LED’s are on, the a/d value entered in should represent 1 inch of water in the tub for the machine’s safety level.
2. Press the STOP/PAUSE key to view the machine’s Total Operation Hour Counter. By pressing either the up or down arrow keys under the TIME display, the display will toggle between "tt" and "tH". The TEMP displays 3 digits: time in thousands for "tt" and the time in hundreds for "tH". Add these numbers together to obtain the machine’s total operating time (ie: if 001 is displayed for tt and 852 for tH, then total operating time is 1,852 hours). This control timer can count to a maximum of 999,999 operating hours.
3. Press the START key to view, set and reset the Programmable Service Timer. By pressing either the up or down arrow keys under the TIME display, the display will toggle between "St" and "SS". The TEMP displays 3 digits: time in hours of operation since the Service Timer ("St") was last reset and time in hours for the Service Timer Limit ("SS"). During machine operation, when the Service Timer reaches the Service Timer Limit, "Ser" will flash in the TEMP display whenever the door switch is activated (ie: end of a program or door open request). This will not prohibit operation of the machine, its function is to remind for periodic maintenance. To set the Service Timer Limit, toggle to "SS" and use the up and down arrow keys under the TEMP display to select a number between 1 and 999. To reset the Service Timer, toggle to "St" and press either the up or down arrow key.
4. Press the STOP/PAUSE key. The TEMP display reads "PAr" and the TIME display reads the model setting. Pressing the TIME up and down arrow keys changes this setting. Set to "d4". Press the START key to exit configuration.

The TEMPERATURE CALIBRATION allows for adjustment of the temperature probe’s readings. With the diagnostics jumper removed, hold both PROG keys and power the unit on.

1. The STEP display will read "CA" and the TEMP will display the current temperature read by the probe.
2. The TIME display will be a number from 0 to 40. The default value is 20. Pressing the TIME up and down keys changes the temperature value. This function can be used for precise calibration of the temperature probe.
3. Press the STOP/PAUSE key to exit calibration mode.

The MEMORY TEST will clear all contents in memory and reset all configurations and programs to default values.

To test the memory:

1. Enter diagnostics mode - when "VEr" is displayed press both PROG keys.
2. Temperature and time displays will count for a few minutes while the test is conducted.
3. If an error is displayed one or more of the EPROM’s may be bad. If no error is displayed the diagnostics mode will continue.
4. Pressing both STEP keys while "VEr" is displayed will reset only the 8 pre-programs and not perform the memory test.
