Problem:
• The PS288 is putting the wrong number of devices into the tubes.
Check this:
) From the Setup window, on the Options tab, ensure that Input and/or
Output options are set to tubes. Click the System icon, then click Gan-
try to open the Gantry window. Click the yellow Vib1 label to move
the PNP head to the first position of the input vibration controller.
Figure 5-67—Enter correct number of devices
) Click the Tubes tab, and then enter the correct number of devices per
tube in the Chips/Tube box.
) Click Save to store the new settings to the package file.
Programmer Errors
Programmer errors discussed:
• Clearing a Programmer Disabled Status
• Fixing Programmer Continuity Failures
• Fixing Programming Failures in All Programmers
• Disabling a Programmer that Fails Self-test
Clearing a Programmer Disabled Status
If the status indicator disappears from any of the programmer outlines, or the
PNP head skips a programmer, first try to clear the programmer disabled sta-
tus.
1. Prepare the system—
1a) On the Run window, click Pause, then click Exit.
1b) From the Setup window, select the Programmers tab.
1c) Note which programmers are disabled. In Figure 5-68 below, Program-
mer 1 and Programmer 4 are disabled.

1d) Click the label for the disabled programmer, and then click the EMPTY
(grey) button. The programmer label changes to grey.
2. Repeat Step 1 for other disabled programmers.
3. Restart job—
3a) Remove any devices in programmer sockets.
3b) Click Run, and then click Run again.
Fixing Programmer Continuity Failures
If only one programmer fails to program devices and continuity failures pre-
dominate in the Statistics window, try the following:
) Move the socket module to another programmer. If the failure moves
with the socket module, check for bent, damaged or worn pins on the
socket and socket module. If the failure persists in the same program-
mer, re-calibrate the device centers for this socket. For information
regarding calibration of the PNP head, see “Teach the Package File” on
page 3-33.
Data I/O does not encourage you to perform repairs on the programmer,
especially if still under warranty. However, you can check for these possible
failures:
Fixing Programming Failures in All Programmers
If all programmers fail to program devices, try the following:
) Check that the Programmer Simulation switch on the Setup window
is OFF.
) Ensure the network hub has power.

Disabling a Programmer that Fails Self-test
If a programmer is not performing and you cannot correct the error, you can
continue to use other programmers after disabling the non-functional pro-
grammer.
To disable a programmer:
1. From the Setup window, click the Programmers tab.
2. Click the label for the failed programmer.
3. Click the black DISABLED button. The programmer label changes to
black and the programmer is disabled.
I/O Controller Problems
Problem:
• The I/O Controller green power LED doesn't light when the START
button is pressed.
Check this:
) Check the power source.
) Make sure that the front circuit breaker is on.
) Check that the loop back plug is inserted into the connector labeled
"Remote ON/OFF 24V" at the rear of the I/O Controller.
) Make sure that the top I/O Controller I/O module lid is screwed tight.
There is a safety interlock switch inside the lid.
) Check the fuse at the rear of I/O Controller; if you can hear the contac-
tor “clunk” internally, and the START switch lights, this indicates the
24 VAC low voltage loop circuit works, but the 5VDC supply is not
working.
Problem:
• The I/O Controller shuts off by itself after a while.
Check this:
) Check for power surges causing the circuit breakers to open.
Problem:
• An output relay is not activating, and its corresponding green LED is
off at the front panel.
