emergency stop button: the machine stops and the drain opens. Unlike the emergency stop
button, resumed formulas start at the beginning of the step in which power was lost, but
chemicals are not injected in the resumed step.
Operator signal cancel button (
buzzer and turn off the operator signal light (see below), or to allow injection of a chemical
programmed to require a signal before injection.
Operator signal light—indicates that the machine has encountered an error or that the operator
must perform some action, such as pressing the start button or unloading the machine. The
operator signal circuit includes a buzzer behind the control panel, and may include an optional
beacon light mounted separately from the control panel.
Liquid crystal graphic display—displays information and help about the machine. The
information on the display changes according to the status of the machine and the function
selected by the operator.
Keypad—allows the operator to communicate with the machine control system. The keypad is
divided into three areas: alphanumeric buttons, general buttons, and function-specific buttons.
Each button may perform more than one function, based on the current machine status. Some
buttons are also used in combinations for additional functions.
Start button (
)—starts the selected wash formula. The start button energizes the 3-wire circuit

to allow the machine to operate.
Stop button (
)—stops machine operation. Like the emergency stop button, the stop button

disables the 3-wire circuit; however, the stop button doesn't require you to manually reset it
after use.

Other buttons and switches are used to control additional standard and optional machine
functions. These miscellaneous controls are located and described in this section.
Mildata/Local selector switch

connects several machines together and allows them to share wash formulas and other data
with the Mildata computer. When this switch is in the Mildata position (
formula number, the machine requests the contents of the formula from the Mildata computer.
