Safety Information
Explanation of Safety Messages
Precautionary statements (“DANGER,” “WARNING”
and “CAUTION”), followed by specific instructions,
are found in this manual and on machine decals. These
precautions are intended for the personal safety of the
operator, user, servicer and those maintaining the
machine.
Additional precautionary statements (“IMPORTANT”
and “NOTE”) are followed by specific instructions.
IMPORTANT: The word “IMPORTANT” is used
to inform the reader of specific procedures where
minor machine damage will occur if the procedure
is not followed.
NOTE: The word “NOTE” is used to communicate

Introduction
Model Identification
Information in this manual is applicable to these models:
Introduction
The “B” electronic control is composed of the
electronic control unit and the control fuse board with
wiring harness. Only an authorized person should look
inside the machine. First TURN OFF POWER, open
lid and remove any cover present. Make sure door lock
circuit has fully discharged. The door unlock capacitor
can retain high electrical charge, even when the
machine’s electrical inputs are disconnected, until it
has discharged. Some machines are equipped with an
“amber” indicator light facing upward in the control
compartment. If this is on, wait until it goes off
(indicating when high voltage in the door lock circuit
has discharged).
Electronic Control Unit
This portion of the control contains the “intelligence” –
the micro-controller and the miscellaneous components
on the printed circuit (PC) board. The board has a
metal cover, which MUST be in place at all times
during machine operation. Operation of the machine
without this cover installed will void the warranty.
The control unit monitors and responds to input, gives
information about the status of the washer and
monitors and responds to inputs from the user
interface (keypad). The control provides signals to the
control output unit, which in turn operates the
components that control the machine functions. This is
located behind the machine control panel.

Control Output Fuse Board
This portion of the control contains the power supply
for the control unit, and also the switching devices
which power the components in the machine, all of
which are on the output PC board. The switching
devices are controlled by the control unit, and are solid
state.
Harnessing
Wiring harnesses are modular – harnesses common to
various configurations are similar, while those specific
to a certain configuration can be added. There are
harnesses for inputs to the control unit, for outputs
from the control power/output unit to the machine
components, and for the main incoming power to the
control power/output unit.
Communications
Central Pay System
(Central Pay System Models Only)
The models are usually designated by the “Prep for
Central Pay” option. The control will accept
communications with the central pay system in order
to perform vending transactions to pay for cycles.
For detailed information on the Central Pay System
Communications, refer to the manufacturer.
Card Reader
(Card Reader Models Only)
The models are usually designated by the “Prep for
Card Reader” option. The control will accept
communications with a Card Reader in order to
perform vending transactions when a card is inserted
to pay for cycles. The Card Reader can also allow the
owner to program and collect audit information.
For detailed information on the Card Reader
Communications, refer to the manufacturer.
