Setup & Operation

SECTION 1 SETUP & OPERATION

1.1

Control Setup

The Accuset 2 is programmed for operation with DC saw-
mills by default. If your sawmill is an 

AC

 model, press and

hold the toggle button when first turning the key switch on.
The display will read “Overwrite Parameters with
Defaults?”. Push the button labeled “Yes” to change the set-
tings for operation with AC mills.

See Figure 1-1. 

Turn the key switch to the accessory (#3) position on DC mills or (#1)

position on AC mills. The Accuset control starts in Manual Mode by default. See the figure
below for identification of the control buttons and display.

About using the Up/Down Adjustment Buttons:

 To make adjustments to a setting,

push the Up or Down arrow buttons to scroll to the desired setting. As you push and hold
the up or down buttons, the setting scrolling speed will automatically increase.

In Manual Mode, the up and down arrow buttons have special functions. You can enter
configuration menus by pushing the Up button. Pushing the Down button moves the saw
head to the nearest nominal inch (or centimeter). 

About the Toggle button:

 Use the Toggle button to exit configuration menus and return

to the main menu. Pressing and holding the Toggle button during startup will reset the
Accuset programming to factory default settings. Pressing the Toggle button in Manual
Mode will place Accuset in Reference Mode.
