Installing a WBK16/LC
CAUTION
Remove the StrainBook from power and disconnect the unit from the host PC and
from all externally connected equipment prior to connecting cables, signal lines,
and/or removing the cover to install or remove components. Electric shock or
damage to equipment can result even under low-voltage conditions.
Take ESD precautions (packaging, proper handling, grounded wrist strap, etc.)
Use care to avoid touching board surfaces and onboard components. Only handle
boards by their edges (or ORBs, if applicable). Ensure boards do not come into
contact with foreign elements such as oils, water, and industrial particulate.
Be careful to avoid component damage while the StrainBook is open. Always remove
the WBK16/LC from the unit before soldering resistors.
Be careful to avoid bending the pins and ensure that the card is correctly oriented.
Note that the associated channel’s two jumpers (located on the StrainBook board)
must be removed prior to installing the card.
You can easily install a WBK16/LC as follows:
Note: If a shunt calibration resistor is to be mounted on the WBK16/LC it should be done prior to the
installing the WBK16/LC. Shunt calibration resistors should be soldered in location R1 on the
WBK16/LC.
1. Review the preceding CAUTIONS.
2. Remove the StrainBook [or WBK16] from power and disconnect the unit from all external
devices and signals.
3. Observe proper ESD precautions.
4. Remove the cover from the StrainBook [or WBK16].
5. Locate the CN-115 channel header(s) in which the WBK16/LC modules are to be installed.
6. If the header socket is occupied, remove the CN-115-1 (or CN-115) to expose the header
socket.
7. Remove one shunt jumper from each of the two 3-pin headers. The 3-pin headers are located
the edge of the CN-115 16-pin header sockets (see following figure).
Note: For each channel the jumper headers are labeled in sets of two: JP101/JP102 for
channel 1, through JP801/JP802 for channel 8. The first digit after “JP” signifies the
associated channel number.
8. Carefully plug the module into the header socket.
9. Re-install the cover to the StrainBook [or WBK16].
CN-115 Headers for Channels 1 and 2
Channel 1 has jumpers removed and has a WBK16/LC
installed. Channel 2 still has jumpers. These would
have to be removed if a WBK16/LC was to be
installed.
Jumpers Removed for WBK16/LC Plug-in
For each channel that is to have a WBK16/LC
installed, jumpers must be removed as indicated
above. Each channel has a jumper header next to
the edge of its CN-115 header.
