11. Solution viewer function
The solution viewer is a check function to help the user to use the SD-29 satisfactorily.
When the sewing machine actually performs sewing with the condition (thread, material, sewing pattern and
the number of revolutions) applied to the sewing process, the solution viewer measures the detection-ON
transit time and difference in the quantity of light received (difference in light quantity between ON and OFF
states of the detection).
11-1. Specification values and handling method
Transit time,
specification value =
120 μs or more
(milliseconds are all acceptable). If the transit time is smaller than 120 μs, the
threshold should be increased.
* The threshold can be changed with the "+" and "-" while the solution viewer mode is
placed in ON.
Difference in the quantity of light received,
specification value =
5500 or more.
If it is smaller than 5500, carry out the procedure described in
again.
If the difference in the quantity of light received is still smaller than 5500 even after you have
carried out tuning of the Sensör, carry out the procedure described in
The specification of the difference in the quantity of light received may differ with the thread to
be used. (The specification value "5500 or more" has been obtained by the test with FUJIX Ltd.
for Resilon #60 thread.)
