9.24 Line Dispensing Adjustments
9.24.1 Valve Feed On Delay - Lines
Usually, when a dispensing valve has been stationary for a period of time, for example at the beginning of a
dispensing program, there is a requirement for the initial dispensing to have a delay applied. This delay is usually
small, such as 50-100ms, which allows the fluid to flow and adhere to the correct position at the start of the pattern.
If no delay is applied, to the first dispensing location, the dispensing will be smaller than the rest or the start of the
line will be without adhesive.
Example of line with and without feed on delay:
From the Line Start screen:
Press
To go to the Points Parameters
screen.
Press
Select an available Feed
function, 1-5.
Press
Up to 5 Feed On delay or 5 Feed Off delay times can be set per program. Valve Feed Off Delay is the time the robot
will stay at the end of the dispensing location before moving to the next dispensing position. No fluid will be dispensed
during to the Feed Off time period. Note that dots use a feed slot and could conflict will line start delay if the same
slot is chosen for a dot and a line.
Press 2, to go to the Teach
Parameters screen.
Input the Feed On delay
time.
Press until the Line
Start screen is reached.

starts the cycle.
Feed on delay, for a dot, sets the dot dispensing time. Up to 5 dots sizes (set by time) can be inputted per program.
Feed Off delay times can be set also. Valve Feed Off Delay is the time the robot will stay at the end of the dispensing
location before moving to the next dispensing position. No fluid will be dispensed during the Feed Off time period.

Press to select
an available “Feed On”
function: 1-5. For a new
program all 5 functions are
available.
Press
Repeat the process for
additional dots, either
selecting the same Feed On
function or selecting a new
one and inputting a different
time.
It is common, when dispensing dots, to see that the first few dots, of a new program, are smaller than the rest, if all
dots are programmed with the same dispensing time. This is due to the fluid being stationary, within the syringe or
pressure tank, whilst the valve is idle. The above process can be used to program the few dots slightly longer in time
to compensate but it is also common practice to dispense 2-3 test dots somewhere outside of the working area, to get
the fluid moving at a normal pace.
Dots 1 -3 require more dispensing time (Feed ON
Delay) to achieve the same volume as the other dots,
in the program.

9.24.3 Line On/Off Distance
On Distance - the robot will move for a set distance before the valve starts dispensing. This prevents the first
dispense being too large, for example in a jet valve line. By dispensing, whilst moving, the first dot is the same size
as all other dots, within the jetted line.
Move and dispense and at the same time.
Move for preset distance and dispense whilst moving.
Off Distance – the robot will continue to move past
the finished dispensing pattern, preventing a build up
of fluid.

Note: If the pattern is 50mm in length and a 5mm
On and Off Distance is set, the actual pattern will be
40mm (50mm – 5mm On – 5mm Off = 40mm).
On/Off Distances should be added to the pattern
length during programming or during editing.
