Making Timed Deposits of Medium to Thick Fluids
(1500XL, 1500DV and 1500D)
You are now ready to test the prefilled, nontoxic, blue test fluid. This
material is representative of thick, non-leveling fluids like sealants,
pastes or greases.
Check your initial settings:
A) Air gauge reads 30 psi.
B) Timer is set at 0.25 (refer to page 6
for complete details on the microprocessor controls).
C) Green tapered tip is on the test barrel.
D) Press the timer bypass button
once so that dashes
appear in the display segments.
(Fig. 1)
Holding the barrel as shown, rest the tip on a piece of paper. Press
the foot pedal until the tip fills and some fluid is pushed out onto the
paper. Repeat this whenever you change to a new tip.
With the tip filled, re-press the timer bypass button and the
dashes will be replaced by the dispense time previously set.
(Fig. 2)
Take the Dot Test sheet and put the tip on a 1/4" circle, holding the
barrel as shown. Press the foot pedal. Check the dot size. Make
several more similar dots and note the size consistency.
Changing Deposit Size, Drawing Stripes
The dot size is determined by the tip diameter, the output air
pressure setting and the pulse time. For large dots, use a large tip,
higher pressure and more time. Normally, you want to use as short
a time pulse as possible. To increase the dot size, slightly increase
output air pressure, or increase tip size, or both.
To make stripes, press the timer bypass button . Dashes replace
the time indication. With the tip in contact with the test sheet, press
and hold down the foot pedal while making a bead or stripe.
Correct angle for consistent deposits.
Remember - always bring the tip
into contact with the work surface
at the illustrated angle. After the tip
is in position, press the foot pedal.
Release pedal and remove tip by
lifting straight up.
