AC/DC
All AC/DC fail in the low level diagnostic
All AC/DC LEDs for AC/DC Power Units installed on the Power Backplane are lit
Fault Isolation :
Check the +/-15V LED on power backplane (voltage generated on Rack Interface)
AC/DC Problems
22 - TroubleshootingPage 6
Verigy Restricted
Failure Condition
All DC/DCs fail in the low level diagnostics
All LEDs on the power control board don’t indicate a failure
Fault Isolation
Check the +/- 15V by measuring the voltage directly on the power control board capacitors (voltage generated on Rack Interface)
DC/DC Problems

DPS cannot be recognized
Fault conditions
Raw power of the DPS is missing (possible defective 12V source from DC/DC; Replacement of DC/DC may be necessary)
OR
DPS was in over-current state and switched off by the SW (Power cycle the system and restart the V93000 s/w. If this does not clear the problem DPS baseboard replacement may be necessary)

Sequencer Time Outs
Failure Condition• SW hangs during bootup for a given amount
of time, ~2 min. • Once SW resumes, missing channels are
seen in the channel lists.
Repair Recommendation• If single channel missing, replace channel
module.• If all four channels on channel module
missing, replace interface module.
22 - TroubleshootingPage 9
Verigy Restricted
Failure Condition
• Tester shuts down in red light condition after SW startup.
• Red ‘Ground Offset’ LED on power backplane is lit.
Fault Isolation
• Manually measure DCOM to chassis, nominal 5k ohm.
• Inspect interface module LED’s on channel boards for
fault condition.
• Run low level diagnostics.
• Pull boards from card cage.
• Other possibilities: shorted pressure sensor, power
control board.
• Once hardware has been identified with grounding
issue, repair or replace.
DCOM Issues

1. SW crash from time to time during running production
2. Starting V93000 software ends with a Fatal error in the report window
Prerequisite:
System can be powered-up
Fatal Errors
22 - TroubleshootingPage 11
Verigy Restricted
This kind of “Fatal error” can be generated by:Defective Channel module
Defective Clock boardDefective Master Clock Ring Defective Data & Address Bus of the Backplane/Control Boards
Defective Communication Path
Steps to find this failure:1. Run several DIS Tests (DFLT & DCIC & DADR)2. Bring the tester down to the minimum configuration, CS1 Only.
8CC (CC1 & CC5) 4CC (CC1 & CC3)
3. Verify physical connections of the clock ring cables on front planes.

Run DIS tests
DFLT DIS Fiber Link Test
DCIC DIS Computer Interface card
DADR* DIS Address & Data Bus Test
• You must manually verify that all installed hardware is identified in this test. It will pass even if some hardware is missing. You must also cycle power on the system after running this test.
NOTE: View di_log_file for results of above tests even if you get a passing result.

Failure tracing to the card cage (CC) level:1. Remove all the jumper boards between the CCs except between
CC1 & CC5 in 8CC TH and CC1 & CC3 in 4CC TH.2a. Disconnect all fiber-optic lines from the control
boards, except 1 line (CC1 on 512 TH or CC5 of 1024 TH).2b. Boot the SW and look for fatal errors. If there are no errors, add cards (control
board, channel cards, clock, DPS, DC/DC) from other card cages, 1 card cage at a time.
2c. When you find the cards that causes the error proceed to step 33. Try replacing the suspect control board/backplane assembly.4. Remove all of the channel cards in the suspect card cage and reinstall them
one at a time.5. Try replacing the clock board in the suspect card cage.

Backplane Assembly InstallationNOTE: It’s a must to use two ‘T’ handlesfor even insertion of all connectors.If only one ‘T’ handle is used, one mustswitch between top and bottom screws every3 turns.
CAUTION: Once top and bottom connectorshave engaged, stop tightening and check forproper alignment on all slots before continuing.

Use the ground pin extractor (left hand drill bit 0,8mm with chuck)
Place the drill on the broken ground pin, use little pressure and turn counterclockwise to remove the broken pin.
NOTE: The drill is very fragile, please handle with the utmost
caution.

There are 2 ways a signal pin can break:
1. Signal pin breaks ~3mm above the isolator.
2. Signal pin breaks right at the isolator.
For case 1, just use needle nosed pliers
and pull the pin.

For case 2:
Use the signal pin extractor and place the tip of the tap on the isolator of the signal pin.
Turn the tap until you reached around 3-4 mm. (3-4/32“)
Pull out the pin
NOTE: The tool is very fragile! Please handle with the utmost caution.
