Model Identification
Information in this manual is applicable to these washer models:
The Electronic Control on the commercial washer is
an advanced, programmable computer that lets you
control most machine features by pressing a sequence
of SELECT CYCLE and SELECT WASH TEMP
pads. See Figure 1.
The Electronic Control allows the user to program
custom cycles, set vend prices, retrieve audit
information, program and run diagnostic cycles, and
program special vend features. Washers shipped from
the factory have a default cycle and wash temperature
setting of PERM PRESS, WARM built in. However,
the user can change the default cycle, or any cycle, as
needs permit.
IMPORTANT: In the event of a power failure, the
Electronic Control will not have to be
reprogrammed. It is designed with a memory
system that will remember how it was programmed
(for a minimum of 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 the
Electronic Control are made before applying power
to or operating the washer.
Glossary of Terms
Power Failure Recovery
If a cycle is in progress and the power fails, the cycle
status is saved in memory for a minimum of six years
without power. When the power recovers, the washer
will resume into the previously active cycle if so
programmed by the owner.
The owner may program a special feature called
POWER FAIL RESET which sets a maximum power
failure duration. To program this feature, see Section VIII, option 22.
If the length of the power failure is greater than the
POWER FAIL RESET time, the washer will return to
the default mode when power is restored.
NOTE: The washer will first spin if the pressure
switch was open at the time of the power failure
before returning to the default mode.
If the length of the power failure is less than the
POWER FAIL RESET time, the washer will resume at
the point it was interrupted when power is restored.
Infra-red Communications
(Optional)
The Electronic Control may be programmed manually
or by an optional hand-held infra-red computer called
the Micro-Wand III
TM

Washer Operation
Start Up
When power is applied to the washer, the control will
display PRICE, INSERT COINS, the decimal point,
and the vend price. The PRICE and INSERT COINS
light will remain lit until the vend price has been
satisfied. The default cycle setting is PERM PRESS,
the wash water fill temperature is WARM, and the
rinse water temperature is COLD. The LED’s will be
lit on PERM PRESS and WARM at the start of the
cycle. See Figure 2. These default settings are owner
programmable. Refer to Section VIII.
“Ready” Mode
Cycle Sequence
Upon the start of a cycle, the Electronic Control will
display TIME REMAINING and the total cycle time.
The appropriate status words will light while the
machine passes through different cycle steps. Any coin
entered after the first fill cycle, and before the final
three (3) minutes of the final spin cycle will be added
to the total coin counter. If coins are added during the
final three (3) minutes of the final spin cycle, the
control will return to the “Ready” mode and ask the
user to satisfy the vend price if needed.
Opening the Washer Lid
Any time the washer lid is opened while a cycle is in
progress, the control will deactivate all motor and
water relays. If the lid is opened during a non-spin
cycle, the control display will freeze and the timer will
stop. Once the lid is reclosed, the cycle will restart
from the point of interruption. If the lid is open during
a spin cycle, the status word UNBALANCE will flash,
the display will appear blank, and the timer will stop
any time other than the final three minutes of the final
spin cycle. If the lid is opened in the final three
minutes of the final spin cycle, the timer will continue
to count down to the end of the cycle. When the timer
reaches 0 minutes, the control will return to the
“Ready” mode. See Figure 2.
Figure 2
The user will be able to select a different cycle or wash
water temperature by pressing a cycle pad when the
machine is in the “Ready” mode or in the first fill
cycle. If not enough coins are entered to satisfy the
vend price, the control will display the remaining vend
price needed to start the cycle. If the first fill was
interrupted to change the temperature (which requires
more money), and the vend price is not satisfied within
one minute, the washer control will go back to the first
selection and the cycle will restart from the point it
was stopped. After the first fill, all key presses will be
ignored, allowing the washer to go through the
complete cycle.
When a cycle is complete, the control will display
TIME REMAINING, “00” until the washer lid is
opened, a key is pressed, or a coin is entered. When
one of these three options occur, the display will revert
back to the “Ready” mode. See Figure 2.
3619811
Signals
There are four options when a signal can be used
during the washer operation. The owner may program
when the signal will sound and at what volume level.
These four options are listed below:
1. End of Cycle Signal
By default, this signal is turned off. If turned on, the
signal sounds for three seconds at the end of a
cycle, at one of the three programmable volume
levels.
2. Signal On Keypad Depression
By default, this signal is set at the lowest volume
level, and sounds for .25 seconds each time a
keypad is pressed. This signal can be programmed
at one of three volume levels.
3. Signal On Coin Drop
By default, this signal is turned off. If turned on,
this signal will sound for .25 seconds each time a
coin is entered at one of the three programmable
volume levels.
4. Signal On Unbalance
By default, this signal is turned off. If turned on,
this signal will sound on for three seconds and off
for two seconds for a total of one minute when the
machine is in the Spin cycle and becomes
unbalanced. The signal will sound until the
unbalance condition is over. The signal can be
programmed at one of the three volume levels.
If the machine becomes unbalanced during the
final three minutes of the final spin cycle, the signal
will not sound.
NOTE: Refer to “Programming the Electronic
Control,” Section VIII, to program signal options.
