2. Assign a unique Site Name to each site
3. Programme for each site, the number of forward (Feed) and reverse auger feed steps.
When sites are selected, the parameter indicators Feed and Reverse show the number of
programmed steps for the auger movements.
4. Set the Stinger Dispense Gap
The dispense gap is the height between the nozzle tip and the upper surface of the product. It
is the height at which dispensing takes place. This can be any value in the range; 0 to 5mm;
zero is the top of the board. The larger the gap, the higher the adhesive dot dispensed. Typic-
ally the gap is set to between 1.5 and 2 times the nozzle inside diameter. For information on
nozzle inside diameters refer to nozzles in the introduction section of this manual.

The Dispense and Measure options are: None (grey) - site measurement is disabled; Measure
Only (yellow) - the laser measures the site at the given co-ordinates to output height corrections;
Dispense Only (red) - adhesive is dispensed at the programmed dispense gap; and Measure and
Dispense (amber) - the site is measured by laser to give height corrections before dispensing
takes place. There is also an option to place sites where a purge operation can take place. Purge
After Downtime sites are programmed as sacrificial sites, and are used to clear the nozzle of any
adhesive, which may have hardened after a downtime period; the sites are denoted by a blue
rectangle; they are the first sites to be added.
