manufacturer's instructions may result in
conditions which can produce bodily injury
and/or property damage.

WARNING
instructions appearing in this manual are not meant
to cover all possible conditions and situations that
may occur. It must be understood that common
sense, caution, and carefulness are factors which
cannot be built into these washers. These factors
MUST BE supplied by the person(s) installing,
maintaining, or operating the washer.
Always contact the distributor, service agent, or the
manufacturer about any problems or conditions you do
not understand.
MDC on the commercial washer is a programmable
control that lets the owner control machine features by
pressing sequences of SELECT CYCLE keypads.
MDC allows the owner to program cycle steps, set
vend prices, retrieve audit information and run
diagnostic tests. Washers shipped from the factory
have a default cycle (PERM PRESS/WARM) built in.
IMPORTANT: In the event of a power failure,
MDC will not have to be reprogrammed. It is
designed with a memory system that will remember
how it was programmed (for up to six years) until
the electrical power is restored.
IMPORTANT: It is extremely important that the
washer has a positive ground and that all
mechanical and electrical connections to MDC are
made before applying power to or operating the
washer.
Glossary of Terms
The following are a few terms and abbreviations to
learn. These are referred to throughout the manual:
Power Failure Recovery
If power fails during an active cycle, the cycle status is
saved in memory. If door is locked when power is
restored, the washer will automatically resume the
cycle. If door is unlocked when power is restored, the
user must press the START keypad to resume the
cycle.
Card Reader Communications
Card Models Only
The control will communicate with a third party card
reader, available at extra cost from various card reader
manufacturers. Contact the card reader manufacturer
of your choice for availability and additional
information.
Four-Digit Display – This term refers to the window
area of the control that displays values.
LED (Light Emitting Diode) – This term refers to the
lights on the keypads and status words of the control.
SELECT CYCLE keypads are used to select the
specific washer cycle. These keypads include
NORMAL/HOT, NORMAL/WARM, PERM PRESS/
WARM, and DELICATES/COLD. The selection of
one of these keypads will light up the corresponding
LED. The default cycle is PERM PRESS/WARM. The
SELECT CYCLE keypads are not active after the first
fill cycle of the washer. Pressing the flashing START
keypad will confirm selection and cycle will begin
when vend is satisfied.
START Keypad
The START keypad is used to start the washer after the
full vend price has been satisfied.
Both the START keypad and the SELECT CYCLE
keypads are used in various combinations for
programming cycles, retrieving audit information,
running diagnostic tests, and other operations
described in Entering the Manual Mode.
LIGHT EMITTING DIODES (LEDs) are used to
indicate the chosen cycle status. Refer to LED
descriptions below.
START LED
The START keypad LED flashes whenever the washer
is not in a cycle and the full vend price has been
satisfied. When the START keypad is pressed, the
cycle will begin or resume. The START LED will shut
off when the START keypad is pressed.
WASH LED
The WASH LED is lit at the beginning of a wash cycle
and will remain lit until the wash cycle is complete.
RINSE LED
The RINSE LED is lit at the beginning of the rinse or
extra rinse cycle and will remain lit until the cycle is
complete.
SPIN LED
The SPIN LED is lit for all spin cycles.
DOOR LOCKED LED
The DOOR LOCKED LED is lit whenever the door is
locked. The door cannot be opened when the DOOR
LOCKED LED is lit.
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. When displaying the time
remaining, the time value is displayed on the right side
of the display. When displaying the vend price, the
value is displayed on the left side of the display.
During diagnostic testing or manual programming of
the control, these digits will display descriptive codes
and values (as described in Entering the Manual Mode).
When power is applied to the washer, the control will
display its software version as “SXXX” (“XXX” is the
version number) for two seconds. If the control was
not powered down during a running cycle, it will enter
the Ready Mode.
Ready Mode
When the START keypad is pressed, the door will lock
and the washer will start. The START LED will stop
flashing and the WASH LED will be lit. The display
will change to show the remaining cycle time on the
right side of the display. The appropriate LEDs will
light while the machine passes through different cycle
steps. Any coin entered after the first fill cycle will be
added to the total coin counter, but the user will not be
able to change cycles.
When a cycle is complete, the Four-Digit Display will
show “00” until the washer door is opened, a keypad is
pressed, a coin or card is entered, or a start pulse is
received. When one of these instances occurs, the
Four-Digit Display will revert back to the Ready
Mode.
Closing the Washer Door
If the door is not closed when the vend price is
satisfied, the Four-Digit Display will show “door”
until the door is closed. Once the door is closed, the
START keypad must be pressed again to lock door and
start cycle. If the door does not lock within 15 seconds
of being closed, “E dl” will be displayed indicating a
door lock error and the machine will shut off.
FLW2R
Figure 2
In Ready Mode, the PERM PRESS/WARM (default
cycle) LED is lit, and the full vend price is displayed
as left justified. The user may select a different cycle,
if desired. (In card reader machines, if the current
cycle has a vend price which differs from the default
cycle, the display will be updated to show the new
price.) If another cycle is selected, the control will
flash the amount needed to satisfy the vend price
shown on the display. If the vend price is not satisfied
within one minute, the washer control will stop
flashing the vend price and return to the default cycle.
The display will continue to show the remaining vend
price needed to start a cycle and will credit any vend
entered by the user.
Vends may be satisfied by a coin drop, start pulses, or
by a third party card reader. If a coin drop is used, the
remaining vend price will decrease with each coin
entry. If start pulses are used, the remaining vend price
will decrease with each received pulse. Once the vend
price is satisfied, the START LED will begin to flash.
If a third party card reader is used, the START LED
will begin to flash when a valid cash card is entered
into the reader.
Signals
There are four instances when a signal may sound
during washer operation. The owner may program the
signal to be turned on or off (refer to Programming MDC, option 6). These four instances are listed below:
1. Keypad Depression Signal
The signal will sound for.25 seconds each time a
keypad is pressed.
2. Coin Input/Start Pulse Input/Card Insertion
Signal
The signal will sound for.25 seconds each time a
coin or start pulse is received or a card is entered.
3. Machine Error Signal
The signal will sound for 15 seconds if an error
occurs.
4. Vend Satisfaction Signal
The signal will sound one second on and one
second off for 10 seconds when the vend price is
satisfied.
