CHECK CONTACTS?
This message indicates that the Z plunger has somehow become out of step and has moved too far up in
the Z motor assembly. At this point, the display may read Z MOTOR CRASH ? only, or it may first read
Z MOTOR CRASH and then blink CHECK CONTACTS?
If the message CHECK CONTACTS? is displayed, the handler may have inadvertently dropped the
device under test onto the contacts. Immediately check the handler contacts and remove any dropped
device.
If the message Z MOTOR CRASH ? only is displayed, the device has been picked up but the Z plunger
and the device are too high up.
You may press the [Clear] button to flush all devices from the handler and start over.
You may also run the Self Adjust Z Procedure as described at the end of Chapter 5, Diagnostics.
CHECK EXIT SEN?
A device may have become jammed when exiting the test site en route to the output shuttle; or the Exit
Sensor #5, may not be working properly. First, visually inspect the exit track and free any jammed
devices. If this does not resolve the situation, run the "Test Site Sensors, 1 Through 8 Diagnostic" as
described in Chapter 5.
CHECK PICK UP ?
The handler has indexed a device but the pick up sensor has not located this device in order to pick it up
for testing/programming. The device may be jammed, or the Test Site/Pick-up Sensor may not be
working properly. First, visually inspect the test site and free any jammed devices. If this does not resolve
the situation, run the "Test Site Sensors, 1 Through 8 Diagnostic" as described in Chapter 5.
CHECK SUM ERROR
The programmer/tester/PC has sent new RAM data to the handler. The handler has calculated the check
sum for the file and it does not match the check sum sent by the programmer/tester/PC.
Press the [Enter] button to skip past this error.
From the programmer/tester/PC, stop the job and start over again.
CHK OUTPUT DOOR
The output door is open and the handler will not operate until the door is closed.
CHK VAC ADJUST
The handler has tried to pick up a device and has failed to detect that the device was already suctioned up
by the plunger’s vacuum. To resolve this condition:
1. Press the [PAUSE] button: HANDLER PAUSED. Wiggle the plunger manually to slightly shift
the device. Watch the red LED on the vacuum generator. When the LED lights up, stop
wiggling the plunger. Press any button on the handler's controller. The handler will
automatically resume operation if the device is now detected.
2. Verify that the vacuum line is installed from the vacuum generator to the plunger. Verify that
the plunger fitting is not leaking.
