The solenoids perform the following operations (confirm that LEDs on
the solenoids turn on for the duration of each test):
•
Blower
— Turns on low air pressure to the output tracks. There is no
air on the input track.
•
Cutoff
— Turns low air pressure to the beam on and off. If you are
running all tests, perform the cutoff test first when you enter the
diagnostic tests. At the start of the diagnostic tests, the beam should
be up. Pressing
3
directs air to the beam, allowing it to rise.
Note: After you run this test you must press
RESET
to exit the solenoid tests
and then reselect the solenoid tests. If you do not press
RESET
, the Beam
Up/Down and the High Pressure tests will not operate correctly.
•
Beam Up/Down
—Directs low air pressure to raise the beam.
Pressing the
4
key allows the beam to lower.
•
Blow Off
—Turns on low air pressure to the chuck tip to assist in
releasing a device. Feel for air blowing out of the chuck tip.
•
High Pressure
—Turns on high pressure. The beam will lower
quicker than the Beam Up/Down test, which uses low air pressure.
•
Vacuum
—Turns on the vacuum generator. Place your finger over
the end of the chuck and feel the vacuum.
•
Clamp
—Activates the programming module holding clamps. They
should both advance and clamp the module.
