4.6 PURGE TOGGLE
This screen performs the same function as in Section 4.5, except it is for the Toggle Valve instead of Valve #1.
This purge routine can be accessed through the front panel LCD in program 98.
From time to time, you may want to run the purge routine from the PDA. This can be
accomplished by selecting “Util” in the Program
mode then select “Purge Main” or “Purge Toggle”
from the drop-down menu.
4.7 SAFE Z
This feature allows a lower “safe” Z height (reference to Z=0) to be set so as to reduce
the time it would otherwise take if the Z head has to return to the “0” position before
each XY movement. It is especially useful if the part is very low i.e. daylight is large.
The safe Z height is the height the Z head will move to before any XY non-dispense movements. Note that the height the Z
head moves to between dispense locations within a program, is dictated by the retract distance specified for that line or dot
type.
The safe Z height should be a high enough position to clear any objects in the machine’s XY envelope. If the Safe Z is not
configured, the machine will move the Z head up to the “0” position before any XY movements.
To set a safe Z height:
1. Select Safe Z from the top right-hand drop-down box.
2. The probe will be actuated and drop down. If a toggle bracket is used, the toggle
will also be actuated.
3. Using the probe and toggle, if applicable, as reference, move the Z head to a
height where both the probe and toggle clears any object in the XY envelope. The
probe should not be touching anything.
4. Tap “Teach”.
5. Your Safe Z height has been set
