Power switch

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.
Note:
The following steps refer to the 1500DV dispenser. For the 1500DV-15
dispenser, refer to
"Making Timed Deposits of Watery-thin Fluids"
on page 22.
The first step is to remove the tip cap from the prefilled 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
❷
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
❷
clockwise.
To reduce the pressure, turn the knob counterclockwise until the gauge
❸
reads
a lower pressure than desired. Then increase and stop at desired pressure.
Push knob in to lock.
Press power switch
❶
to turn on the dispenser. The digital display will show
the time that was set when the dispenser was turned off.
Set the digital time to 0.25 seconds as follows:
On the display and control pad
❹
,
press the decimal button until the
decimal is moved to the left and appears in the left display segment. This puts
the time range within 0.00 to 0.99 seconds. (
Fig. 1)
Now, use the time set buttons
❺
to set the length of the air pulse.
Press the
bottom right button until a 5 shows. Then press the bottom middle button until
a 2 shows. Finally, press the bottom left button until a 0 shows. This display is
equal to 0.25 seconds.
(Fig. 2)
Be sure barrel vacuum control
❻
is turned off.
Note:
A separate vacuum control
❼
powers the pickup pen. The second foot
pedal
B
turns on the solenoid that controls the vacuum. Turn the control
counterclockwise until sufficient vacuum is obtained. Place the pad on the
component and press the foot pedal to provide pickup vacuum. Position the
component where needed and release the foot pedal.
Please continue to page 20 for test procedures.
Refer to pages 6 - 7 for
complete details on the
microprocessor controls.
