Preliminary Information
About the Control
This control is a programmable computer that lets the
owner control most machine features by setting dip
switches and pressing buttons on the back of the
control.
The control allows the owner to program custom
cycles, set vend prices, retrieve audit information, run
tests and other programmable features. Refer to
Programming Control for a list of features.
IMPORTANT: In the event of a power failure, the
control will not have to be reprogrammed. It is
designed with a memory system that will remember
how it was programmed until the electrical power
is restored.
IMPORTANT: It is extremely important that the
machine has a good ground connection and that all
mechanical and electrical connections to the control
are made before applying power to or operating the
machine.
Glossary of Terms
The following are a few terms and abbreviations to
learn. These are referred to throughout the instructions.
Display – This term refers to the window area of the
control that displays words and values.
LED (Light Emitting Diode) – This term refers to the
lights next to the status words of the control.
Power Failure Recovery
If a cycle is in progress and the power fails, the cycle
status is saved in memory. When the power recovers,
the machine will resume into the previously active
cycle if the power outage is less than five (5) seconds
and the door is closed and locked.
If the length of the power failure is greater than five
(5) seconds, the control will enter Start Mode and
require pressing the start switch. If the power failure is
greater than five (5) seconds and OPL Mode is
enabled, the cycle can not be resumed.

Display Identification
Light Emitting Diodes (LEDs)
(Refer to Figure 1)
Light Emitting Diodes (LEDs) are used to indicate the
cycle status and door lock information. See below for
information on each LED.
WASH LED
Wash LED is lit during the wash and prewash portion
of the cycle.
RINSE LED
Rinse LED is lit during the rinse portion of the cycle.
SPIN LED
Spin LED is lit during the Final Extract portion of the
cycle.
DOOR LED
Door LED is lit whenever the door is locked. The door
can’t be opened when this LED is lit.
BLEACH LED
Bleach LED flashes one (1) second on and one
(1) second off when the bleach dispenser is flushing.
Four 7-Segment Digits
The 7-Segment Digits are used to display the time
remaining in a cycle, vend price, error messages and
descriptive codes. During manual programming of the
control, these digits will display descriptive codes and
values (as described in Entering the Manual Mode).

Washer-Extractor Operation
Start Up
When power is applied to the machine, the control will
display its software version as “S xx” (“xx” is the
version number) for one (1) second. If the control was
not powered down during a running cycle, it will enter
the Ready Mode. The display will show “PAUS” if
there is coast-down time remaining.
Ready Mode
For coin models, the full current vend price for the
cycle appears in the display.
To start the cycle, the user must satisfy the vend price
(on coin models) and then press the START switch.
The user will be able to select a different cycle/water
temperature by turning the CYCLE/TEMPERATURE
selector switch when the machine is in the Ready
Mode or in the first fill step.
Partial Vend Mode (Vended Models
Only)
The control enters this mode when part of the vend
price has been entered, but not enough vend is entered
to satisfy the vend price. The control will display the
remaining vend price needed to start the cycle.
Signals
1. Coin Models - A signal will sound for a quarter
of a second for every coin insertion.
Start Mode
The control enters this mode when the full vend price
is satisfied, the vend price is zero or the control is in
OPL Mode. The display will show “PUSH” for one
(1) second, “Strt” for one (1) second and the current
cycle time for one (1) second. If Start Mode is entered
because the vend price is zero, the display will show
“FrEE”.
After pressing the START switch, the door will lock
and the cycle will begin.
Door Locking Mode
The control enters this mode after the START switch is
pressed in Start Mode. The control stays in Door
Locking Mode until it confirms the door is closed and
locked.
Run Mode
The control enters this mode when a cycle is running.
The time remaining appears in the display, the status
LEDs are lit and the loading door is locked.
Changing Cycles
Cycle/temperature can be changed anytime during the
first fill step.
Door Unlock Mode
The control enters this mode after cycle has ended. The
control waits for confirmation that door is unlocked.
Once confirmation is received that door is unlocked,
control will enter End of Cycle Mode.
End of Cycle Mode
When a cycle is complete, the control will display “00”
until the washer door is opened, cycle switch is changed,
or a coin is entered. When one of these options occurs, the
display will revert back to the Ready Mode.

Special Features
Programming Control
The control allows the machine owner to program the
control with the use of buttons on the back of the
control. Cycle and vend options may be programmed.
For details on programming cycle and vend options,
refer to Programming Control.
Collecting Audit Information
The control will store audit information in its memory
that can be retrieved in the Manual Mode.
The audit information stored is total cycle counts and
total Rapid Advanced Cycle counts. The counters are
not resettable.
Production Test Cycle
Special test features built into the control allow the
owner to run specific tests.
The Production Test Cycle is entered by connecting
the test harness to the test input on the control.
For detailed information, refer to Production Test
Cycle.
Rapid Advance Feature
This feature allows the user to quickly advance
through active cycles. This feature is useful when tests
must be performed immediately on a machine
currently in an active cycle. In this case, the user can
quickly advance through the cycles to Ready Mode. At
this point, the user can perform the required tests and
then return the machine to the point it was interrupted.
For detailed information on using the Rapid Advance
feature, refer to Rapid Advance Feature.
Coin Drop
The control will accept pulses from a single or dual
coin drop to satisfy vend price. Each coin drop will
have the ability to start a cycle.
OPL Mode
This feature allows the user to start a cycle without
satisfying the vend price.
For details on enabling OPL Mode, refer to
Programming the DIP Switch.
Power Save Mode (OPL Models
Only)
This feature powers down the display after machine is
idle for 4 minutes and 15 seconds.
To “wake up” the machine display, press the START
switch.
The Power Save Mode is a feature of the control and
cannot be disabled in programming.

Opening the Top Cover
To manually program the control, the top cover must
be opened. Opening and closing the top cover trips a
switch which allows access to various programming
options.
The top cover is located on the top of the machine.
1. Unlock top cover.
2. Slide the top cover forward slightly to move the
notches away from the pegs on the front of the
cabinet.
3. Lift the top cover up. To completely remove, lift
top cover away from both top cover hinges. Refer
to Figure 2.

United States the coin value for one quarter would be
measured in cents (25). Therefore, the coin value
entered for one quarter would be 0025.
If the Vend Price (option 1) is set for “0075”, and the
Coin Value is set for “0025”, the vend price displayed
will decrease by .25 for each coin entered.
How to Program Coin #1 Value

Entering the Manual Mode.
2. Press the Right or Left Programming button to
scroll through the programmable options until
“dEn1” appears in the display.
3. When “dEn1” appears in the display, press the
Right and Left Programming buttons at the same
time. The current Coin #1 value will appear in
the display.
4. Press the Right or Left Programming button to
increase or decrease the Coin #1 value.
NOTE: The coin value can be set from 1 to 9,999.
The default value is 25.
5. Press the Right and Left Programming buttons at
the same time to save the new value. The next
available programming option will be displayed.
