Dot Beads
When this bead type is enabled, the normal bead length is broken into dots.
The size of each dot is programmed in 0.1 ms increments with a maximum
value of 50.0 ms. The spacing between the dots (pitch) is programmed in
millimeters from 2 - 9999 mm.
Finally, the position of the dot on the product is defined. Four dot series can
be programmed for the product.
Once the Dot bead is selected, all the beads for that channel will be in dot
mode. In this mode the start position of the dot pattern will be speed
compensated but the size of the dot is not.
NOTE: Interval (also known as pitch) is the distance from the start of one
bead to the start of the next bead
.
NOTE: If the production machine speed is above the maximum dot speed
(Max Dot), a normal bead is applied (also refer to Page 15).
NOTE: When this mode is active, masking of the trigger has no effect (also
refer to Page 31).

1. To set the size of each dot (Time):
a. Press the or button for the cursor to appear beside the numeric
value.
b. Press the or button to enter the desired gun-on time value
from 0.1 - 50.0 ms.
2. To set the Pitch between dots:
a. Press the or button for the cursor to appear beside the numeric
value.
b. Press the or button to enter the desired pitch value from
2 - 9999 mm.
3. After setting Time and Pitch, press the top SETUP button to open the
Dly/Dur setup menu screen, refer to Normal Beads.
4. Press the or button for the cursor to appear beside Dly (delay).
5. Press the or button to set the desired delay value from
0 - 9999 mm.

Random Dot Beads
When this bead type is enabled, the normal bead duration is broken into
dots. The size of each dot is programmed in 0.1 ma increments with a
maximum value of 50.0 ms. The spacing between the dots (pitch) is
programmed in millimeters from 2 - 9999 mm.
The pattern controller automatically determines the length of each product
as it passes the trigger and then sizes the beads to fit the product.

NOTE: If the production machine speed is above the maximum dot speed
(Max Dot), a long dot bead is applied (also refer to Page 51).
NOTE: When this mode is active, masking of the trigger has no effect (also
refer to Page 31).
