Zeroing the Z-axis Using the Spark Detector
If you set zero using the optional ACU-RITE spark detector, you can easily com-
pensate for spark gap and electrode erosion from one cut to the next.
1.
Preset the depth of the cut (explained on page 11).
2.
Verify the readout is in ABS mode. If not press
A
.
3.
Press the
z
key next to the
Z
key once.
The Z-AXIS display will look like this;
“_ _ _ _ _ _ _ 0”.
4.
Start the cut. When the first spark is detected,
the readout sets the top of the workpiece to zero.

When the retract point is reached, any programmed dwell and/or retract will
occur.
EDM Parameters
Pressing the
e
key allows the operator to access four EDM function parameters.
When
e
is pressed, “EDM” is displayed along with a flashing dash. A flashing dash
indicates that the key to the right of it has a function. Pressing the
X
key will
advance you to the next parameter. Pressing the
Y
key will allow you to change the
parameter setting. Pressing the
C
key will clear information entered or take you back
to the normal display.
Enable
This parameter allows you to suspend all EDM functions. When “ON” the Dwell,
Retract and Position Hold relays are active. When “OFF”, all relays remain in their
relaxed states. Turning off all functions allows you to setup a job without the concern
of activating the retract or dwell functions accidentally. To indicate all functions are
off, the entire Z-axis display will blink.
