LVDT Jumper Settings
The following may be set on the signal conditioning module by means of jumpers: Buss
out pin assignments, buss in pin assignments, bussed in signal sum and difference, and
input amplification.
Output Jumpers
To buss a signal from one Trendsetter II to another connect an interface cable, Edmunds
#4550200, from the Input/Output "A" connector on the rear of one column to the
Input/Output "B" connector on the rear of the next column. Multiple columns may be
connected in this way.
If a signal is to be bussed out to another Trendsetter II or external device the pin
assignment, from 1 to 6, must be set using the jumpers as follows.
Note:
To avoid buss
contention, assign one pin per signal.
ANLG OUT (Analog Output)
- Is a high level output, +/-2.5VDC, of all signals after
they have been amplified. This output can be assigned to any pin number 1
through 6.
SUM OUT -
Use this jumper to assign a pin number, 1 through 6, to buss out the sum of
all inputs including any auxiliary inputs. For example, if input A and input B are
connected to LVDTs in a gage fixture and inputs C and D are bussed in from
another Trendsetter II then the SUM OUT signal will be equal to A + B + C + D.
This is a low level signal.
A OUT -
Use this jumper to assign a pin number, 1 through 6, to buss out the signal from
input A. This is a low level signal.
B OUT -
Use this jumper to assign a pin number, 1 through 6, to buss out the signal from
input B. This is a low level signal.
NOTE:
Each pin can have only one input or output assigned. For example, if A OUT is
assigned to pin number 6 then no other input or output can be assigned to pin number 6.
NOTE:
If an output is not used place the jumper on only one pin .
For an example of the use of the output jumpers consider a gage fixture with two LVDT
probes measuring a part's outside diameter. The two LVDTs are inputs A and B on the
first Trendsetter II column. Jumper "A OUT" is set to pin number 1 and jumper "B
OUT" is set to pin number 2. An interface cable, Edmunds #4550200, is connected to the
Input/Output "A" plug on the rear of the Trendsetter II and to the Input/Output "B" plug
on a second Trendsetter II with an E8302 module. A second cable is connected from
Input/Output "A" of the second column to the Input/Output "B" plug of a third column.
The input A signal from the first column can be bussed in to either or both of the other
columns from pin number 1 by setting the appropriate input jumpers for input C or D on
the E8302 modules of the second and/or third columns or the input B signal may be used
from pin number 2.
