Changing Deposit Size, Drawing Stripes
The dot size is determined by the tip diameter, the air pressure output 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.
Dot Test with Green Tapered Tip
First, follow the settings illustrated on the right, and you will get dots about
the size shown. Try other times and pressures to see how easy it is to get
just the dot size you want.
Dot Test with Blue Tapered Tip
These tests show the effect of using a smaller diameter tip.
Replace the green tip with the blue (22 gage) tapered tip. Now, turn on the
timer bypass switch and press the foot pedal to fill the tip. Then, turn off the
timer bypass switch (yellow light out) and press the foot pedal.
To make stripes, press the timer bypass switch (yellow light on). With the tip
in contact with the test sheet, press and hold down the foot pedal while
making a bead or stripe.
Programmable Timer
Each 900 series dispenser has a digital timer with programmable time ranges.
The DIP switch that controls the timer has been set at the factory for a time
range of 0.01 to 1.0 second, with the initiation set to MOMENTARY contact.
If a longer time range is required, or foot pedal operation needs to be changed
from momentary to maintained, choose the appropriate dip switch setting in
the chart below.
