Solenoid Test
Run this test to evaluate the operation of the solenoids.
Note: You can also manually test each solenoid by pressing on the actuator
button on the side of each solenoid.
WARNING:Performing these diagnostic procedures will expose you to
harmful high voltage. Only a service technician trained on
electromechanical equipment should perform the
diagnostic tests described in this manual. If you are not a
service technician who has been trained on the 2500, do
not lift the main plate as described in some of the
diagnostic test procedures.
From the Diagnostics menu, press
2
. The 2500 displays:
When you test a solenoid, confirm that the action it controls is taking
place. If it is not, check the LED mounted directly on the solenoid to see if
it is illuminated. Refer to Figures 5-15 and 5-16 for the location of the
solenoids. An illuminated LED on the solenoid indicates that it is active.
Each solenoid is turned on and off by a control circuit on the handler
controller board.
PRESS NUMBER OF SOLENOID, E TO EXIT
1 - UNUSED 4 - BEAM UP 7 - VACUUM
2 - BLOWER 5 - BLOWER OFF 8 - CLAMP

To see the LEDs on this board (located in the 2500’s base), loosen the two
corner screws that hold the main plate in position on the base and raise
the main plate. Figure 5-19 shows the location of the board. An LED on
that board illuminates when the solenoid control circuitry is sending a
signal to activate the solenoid.
If the LED on the solenoid is not on during the test, make sure that the
logic drive circuit associated with that solenoid is operating correctly.
Refer to the table below to determine the LED associated with each test. If
the LED is on during the test, you can be fairly certain that the solenoid
driver is getting the proper logic signal.
Refer to the table below to select and enter the test number for each
solenoid you wish to evaluate. Press
ENTER
. Then press
START
to begin
the test.
