Touch 1 / 1100-H+ Null Relay Modification

BACK STORY:

Cirris Systems implemented a new "Null Relay" Touch1/1100H+ scanner daughter card design in January 2010. The new design resolves "high" contact resistance issues that began occurring in Omron relays after changes were made by the manufacturer to bring the components into RoHs compliance. Most frequently, this condition would be encountered as a failure in the zero-ohm portion of the performance check process with failure measurements ranging from a few tenths of an ohm to several ohms, although it could also produce high resistance failures while testing.

TESTERS AFFECTED:

The new null relay scanner daughter cards can be used in all 1100H+ testers and in Touch1 testers with serial numbers 25000-T1 or higher. The new null relay cards cannot be used in the Signature 1000H+, 1000HX, 1000HN testers or in Touch1 testers with serial numbers beginning with the digits "10" (i.e. S/N 10XXX-T1).

SOFTWARE VERSION:

EXCEPTIONS:

It should be noted that customers using equipment that meets the hardware requirements, but who are unable to upgrade to the required software versions for other reasons, will not be able to use the new scanner daughter cards in their testers. Such circumstances may include those companies that cannot upgrade their tester software because they have had their test processes approved in accordance with FDA regulations and cannot make any changes to their processes, including software modifications, without the prior approval.

Frequently Asked Questions:

How can I tell the new null relay scanner daughter cards from the older scanner daughter cards? The new scanner daughter cards released January 2010 will include a RED barcode label on the edge of the card and have the top corner of the printed circuit board card clipped at a 45 degree angle, as shown below.

Can I mix null relay scanner daughter cards with the older "white-labeled" scanner daughter cards?
Yes, the new 'null relay' scanner daughter cards can be used with older scanner cards in the same Touch1 or 1100H+ tester as long as the tester meets the hardware and software requirements noted above.

What about my older Cirris HiPot testers that do not support the new scanner daughter design?
Cirris will continue to sell and support high voltage scanner daughter cards for the 1000H+, 1000HX, 1000HN and older T1 testers. Also, keep in mind that the scanner daughter cards from existing 1000H+, 1000HX, 1000HN and older Touch1 testers can often be transferred to new 1100H+ or Touch1 testers. Call Cirris for upgrade pricing details 1-800-441-9910.

How will I know if 'null relay' daughter cards have been installed in a tester that cannot accommodate the cards due to hardware or software incompatibilities?
The tester will report the error messages detailed in the table below.
