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.
To exit the solenoid test and return to the Diagnostic menu, press

displays:
WARNING:To perform the motor tests, the hood has to be raised for
better visibility. To avoid electrical shock or mechanical
injury, these tests should be performed only by a service
technician trained on electromechanical equipment.
The beam moves quickly. To avoid injury, keep your
hands, hair, and loose clothing away from the path of the
beam while running these tests.
Refer to the motor test table and Figure 5-17. Press the number for the
motor you wish to test, and then press
START
to activate the motor.

Note: The beam traverse motor (tests 1 and 2) may appear to stall or fail. This
could be caused by a dirty or dry lead screw. Refer to page 5-63 for the lead
screw cleaning and lubricating procedure. If this does not resolve the
problem, adjust the motor speed by entering the STOP command

CAUTION: Be sure to open the hood during traverse motor test 1 to
prevent the beam from hitting the hood shock mount.

This option inserts devices into the programming module without
programming them. It differs from the diagnostic tests because it allows
you to assess the following system operations under operating conditions
without having to program devices:
• Beam movement
• Vacuum generator functionality
• High and low air pressure
• Applying labels to devices
To select Cycle Parts, press
4
from the Diagnostic menu. The 2500
displays:

Use the arrow keys to select the pin 1 position of the device as it goes into
the receiving tube. Press

The next display prompts you to enter the number of parts per tube. The
default value appears in parentheses.
