Compressed Air Requirements
The i3070 uses compressed air to pressurize air cylinders that actuate fixture
pull-down towers. Pull-down towers are used to pull and hold a fixture down onto
the testhead, enabling contact between the pins on the fixture and the
spring-loaded interface pins in the testhead.
Connecting Air to the Testhead
Install compressed air lines using rigid line to a point near the testhead. An air cutoff
valve is recommended for situations when the air line must be disconnected.
When the system is installed, connect the air to the testhead with a flexible line that
has a Hansen Series 3000 Push-tite 1/4-inch female coupling or equivalent. The
testhead air input connector is shown in Figure 7-1.
