Adding Additional Modules
To add additional modules you will need to wire in additional Eurocard connectors to the back
panel. You must have a soldering iron and 24AWG bus wire as well as insulated wire to
connect any outputs that are required to the display or the back panel.
Warning: The integral power supply in racks utilize high voltage
(120 or 240VAC). Unplug the unit before servicing.
1) Using the back plane template provided in fig. 15 map out the wiring of the unit.
Power and ground connections from the power supply are shown in the diagram.
Measuring channel and function cards I/O is shown in tables at the top of the
template. You should refer to the specific manual on the module you are adding
for further pinout information. The measuring channel sensor SMA pigtail
connectors will already attached to the Eurocard connector.
2)
Determine the connector required:
If you are adding a measuring channel:
you will need to have the 853503-001 or 853503-002 (depending on whether the
measuring channel has one or two coils) connector with the coaxial bulkhead
SMA connector (which comes with a measuring channel).
If you are adding a function card:
you will need to have the 826020-002 Eurocard connector which comes with a
function card.
3) Insure that the power cord is removed from the unit
4)
Remove the back panel
On subracks:
you should only remove two screws and carefully flip the panel up to avoid
breaking any wires already connected.
On instrumentation cases:
you should remove the top panel and the back panel being careful not to put
any excess strain on connections already made.
5)
Install the connector spaced the same number of holes as the rest of the
connectors in the unit (there should be 6 empty holes between connectors). The
2 M2.5x6 screws (supplied -- Kaman PN 826028-146) should be used to secure
the connector firmly in place. If you are installing a measuring channel and
have and SMA pigtail it is best to wait until later to secure the SMA to the back
panel.
