PS288 Owner’s Manual 5—25

WARNING: Failure to replace the laser vacuum filters at the

appropriate intervals could create a hazardous operating environ-

ment.

WARNING: This procedure should be performed only by quali-

fied service personnel who have successfully completed

Data I/O's laser training class. This procedure involves exposure

to hazardous by-products from the laser marking process.

WARNING: Electric shock hazard. Shut down the PS288 (see

“Shut Down the System” on page 3-12) and turn off the main

power switch.

WARNING: Hazardous materials. Wear safety goggles and dis-

posable protective gloves. Do not clean the laser vacuum filters by

blowing with compressed air, shaking, or using any method that

allows the particulate trapped by the filters to be released into the

work environment.

To replace all filters:

1. Prepare the system—

1a) Verify that the PS288 is shut down and the main power switch is in the

OFF position.

1b) Remove lower back laser housing panel by removing the eight screws

highlighted in yellow in Figure 5-25.

2. Take safety precautions—

Put on the disposable protective gloves and open the sealable plastic

bag.

3. Detach vacuum hose—

3a) Loosen the clamp holding the vacuum hose to the extractor top and

detach the vacuum hose from the extractor top. See Figure 5-27.

3b) Carefully set the vacuum hose aside.

WARNING: Hazardous materials. Do not allow particulate mat-

ter in the vacuum hose to be released into the work environment.

4. Release spring clips—

4a) Release the four spring clips (one on each side) that secure the extrac-

tor top to the filter system. See Figure 5-28 for location of one spring

clip.

4b) Remove the extractor top and set aside.

5. Remove filters—

5a) Remove all four filters and carefully place in the sealable bag.

5b) Pull off the disposable protective gloves and place in the sealable bag.

5c) Seal the bag and dispose of as hazardous waste.

WARNING: Numerous government regulations apply to the stor-

age and disposal of hazardous waste. Ensure that contaminated

filters are properly labeled and stored in your hazardous waste

storage area. Also, make sure that they are not stored on your site

longer than government regulations allow (the typical limit is 90

days). Check your government (local, state, and federal) regula-

tions for hazardous waste storage requirements.

6. Replace filters—

6a) Replace the pre-filter with Data I/O Model Name Pre-Filter, Polyes-

ter.

6b) Replace the pleated filter with Data /O Model Name Filter, Panel,

Pleated.

6c) Replace the HEPA filter with Data I/O Model Name Filter, HEPA,

Particle, BD Frame.

6d) Replace the carbon filter with Data I/O Model Name Activated Car-

bon Cell, 3lb NET.

Testing and Calibrating FlashCORE Programmers

To optimize programming yields, voltages within the FlashCORE program-

mer need to be calibrated once each year.

You will need:

• Diagnostic Adapter Board (DAB), Data I/O part number 910-2200-003

(or later).

This Diagnostic Adapter Board (DAB) detects and isolates problems related

to FlashCORE programmers containing either RPX-Lite DW or

DW-LGMEM. The DAB tests the Waveform Circuit Board and Backplane

Circuit Board. The DAB can also be used to locate problems that have not

yet shown symptoms.

Data I/O suggests performing the programmer diagnostic test annually. This

DAB requires a minimum firmware version 03.00.00.C.

The DAB performs these nine tests:
