1000XL -- Setup for Testing
Power switch 6 should be off.
The amount of material dispensed each cycle depends on the
combination of air pressure, time of air pulse, viscosity of material
and dispensing tip size.
The first step is to remove the tip cap from the pre-filled barrel of blue
test material (twist and pull). Replace it with an 18 gage (green)
tapered dispensing tip. Press the tip on and twist clockwise to lock.
Pull out air pressure regulator knob 1 until it "clicks" into the unlocked
position. Turn clockwise to adjust the air pressure to 30 psi (2.1 bar)
for the initial tests.
Always set the pressure desired by turning the air regulator knob 1
clockwise. To reduce the pressure, turn the knob counterclockwise
until the air gauge 2 reads a lower pressure than desired. Then
increase and stop at desired pressure. Push knob in to lock.
Set the time control 3 to #7. Dispense cycle time increases from
0.01 second minimum to 1.0 second as knob is turned clockwise.
Be sure vacuum control 4 is shut off. In the initial tests, the vacuum
pressure gauge 5 will indicate zero pressure. You may notice the
needle on this gauge (when turned off) will jump slightly after each
cycle. This is normal.
Press power switch 6 to turn on the dispenser. It will light green.
Press timer bypass switch 7. It will light yellow. In this operation
mode, the timer will be bypassed to fill the dispensing tip before you
begin testing. A continuous flow of material will occur as long as the
foot pedal is pressed.
