SECTION 7 - MAINTENANCE INFORMATION
GENERAL CLEANING
•
Isolate the electrical power from the chassis and ensure that no user I/O signals are being applied.
•
Wipe the product & chassis surfaces with a clean dry anti-static cloth only.
SOFTWARE UPDATE
For PXI modules operating in a PXI chassis, no module software updates are required. For the latest version
of the driver please refer to our web site
where links to our Software Download page will
provide the latest version of the driver software for the various programming environments encountered.
For PXI modules which are supported in one of Pickering Interfaces’ Modular LXI Chassis (such as the 60-102B
and 60-103B) no module software update is required. If the module was introduced after the LXI chassis was
manufactured the module may not be recognized, in this case the chassis firmware may need upgrading. This
is a simple process which is described in the manual for the Modular LXI Chassis.
SWITCHING SYSTEM TEST TOOLS
We recommend the use of
e
BIRST
to provide a check of the correct operation of relays and to identify the
location of any faulty relay. For more information on

PERIODIC MAINTENANCE
This product and its corresponding chassis do not require any periodic maintenance.

Refer to the Warnings and Cautions at the front of this manual
RELAY LOOK-UP TABLES
The following pages provide a cross reference between the signal paths of the product and the physical relays
on the PCB. The tables can be used in the fault finding process and should be used in conjunction with the
corresponding PCB layout diagrams to identify the position of faulty relays. Users of
e
BIRST
switching system
test tools do not need to use this information to locate faulty relays.
NOTE
This is a very high density design, as a consequence removal of the relays can be awkward since there is
no access to the relay sides to grip them during de-soldering. Further guidance on removal can be obtained
on our Knowledgebase http://wiki.pickeringtest.net/ReRelays or search the Knowledgebase for
“Replacing Relays”.
